(#) Screen arm and fluoroscopic screen. In the eaihei models there is no provision for raising or lowering the fluoroscopic scieen with respect to the screen arm. With the old type the screen arm and fluoroscopic screen are rigidly connected after the scieen has been attached with the lock handle. When replacing the old type screen arm, 9R05244 (fig. 10) without changing the old type fluoroscopic screen assembly (figs. 11 and 12) be sure to specify the correct number. When replacing the old type fluoioscopic scieen assembly, it will be necessary to use the new type screen arm, 9R05246 and the fluoroscopic screen assembly complete, 9R05286. (See figs. 13 and 14.) The later models of the X-ray field unit table unit provide an adjustment for the screen-target distance on the fluoroscopic screen.

W Localizer scale. In the earlier models the localizer scale was shifted manually, with two knobs. The later models provide a small adjusting knob (fig. 15, part 9) for the localizer scale.
(c) Cassette support for horizontal roentgenography. In the early models the X-ray field unit portable grid, 9607000 (fig. 16), had to be ordered separately from the table unit, before horizontal roentgenography with a grid could be done. The wafer grid supplied with this unit was of a specially adapted design. In the case of the new models it is not necessary to order a grid or cassette holder separately. The new tables are equipped with a cassette lilting device assembly (fig. 17) for horizontal roentgenography and stationary grid, which is mounted beneath the fluoroscopic screen during shipment. This new grid is smaller than that supplied with item 9607000 assembly and may be used during fluoroscopy as well as horizontal roentgenography.
fd) Protective shield. The newer models of the field unit table unit are equipped with a protective shield, 9ROS238 (fig. 18) which can be mounted on the table for protection of legs and feet of the operator.
(e) Focal distance checking gauge, 9 R0 599 4 (fig. 19, part 10). This gauge is supplied with the newer models and will be discussed in paragraph 17.

This is done by first taking out the two cable receptacle plugs and releasing the braided strap from the buckle. A slight pressure on the upper retaining ring (fig. 30, part 11) will release the upper end of the tube. Grasp this upper end and lift upward until the tube is released from its mounting. Take particular care of the two moulded cable receptacles when removing the tube head since they are easily broken when struck by any hard object.
(2)	The shockproof cables (fig. 30, part 4), can be removed next by pulling the cable shipping drawer (fig. 30, part 3), out of the chest and placing the drawer as in figure 30. Release the braided strap from the buckle. Pull the cable terminal protectors out of their sockets to the limit of the cord length and unscrew the protectors from the cable terminals.
(3)	The blower motor cable (fig. 30, part 7), as well as the aluminum filters and lead aperture plates (fig. 30, part 18), may be removed by opening the cylindrical compartment door in the center of the cable shipping drawer.
d.	Chest MD X-4 (9608808 or 9608810). (1) Turn the two large wing nuts (fig. 7, part 3), until the two remaining clamps (fig. 7, part 2), can be lifted out of the holes in the handle.
(2) The control unit may now be removed and the outer and rear compartments opened.
(3) The left compartment contains the X-ray operator’s goggles and the footswitch assembly. The rear compartment contains the line cable and protective shield. The right compartment contains the lead gloves, localizer lamps, and the hand timer.
10. Assembling
a. When Chest MD X-l, (new type or old type), is supplied. (1) After the chassis, the lower mast section, and cross-arm carriage have been assembled, join the two separate center sections of the vertical mast to the corresponding lower mast columns.
(2)	Remove the end plate assembly of the horizontal cross arm and carefully insert the twin tubes of this arm into the end of the vertical cross-arm carriage identified by the nameplate “U. S. ARMY FIELD UNIT.” Be sure to guide the twin tubes through the double set of ball bearings and through the shift lock sleeve carefully. Insert the horizontal tube arm into the carriage the full distance and replace the end plate assembly to its original position. (See fig. 31.)
(3)	Complete the mast assembly by joining the upper section of the mast to the center mast sections.
37
Figure 31. Chassis, lower mast section, cross-arm carriage, part of Chest MD X-l, old type, item No. 9609005.
(4)	Unfold the draw bolts and insert them into the top of the mast. Turn the wing screws so that the threaded ends of the draw bolts will engage. Tighten the draw bolts to make the entire mast assembly rigid.
(5)	Insert the high-tension transformer into the well of the carriage. The lock side of the transformer must be facing the mast.
(6)	Release and fold back the cover of the transformer chest.
(7)	Insert the hand crank into the socket provided on the cross-arm carriage.
(8)	Raise the carriage up two-thirds of its travel.
(9)	Remove the two cable supports from the chest and place them in position on the slide provided on the top section of the mast. The slide should be approximately at eye level when attaching the supports. (See fig. 32.)
38

39
(10)	When assembling it is advisable to mount the base handle so that the unit may be moved more easily. (New type).
(11)	Inflate the tires to 35 pounds pressure. (New type).
(12)	Carefully remove the cables, one at a time, from the shipping drawer. Be sure that the four cable inserts as well as the four cable receptacles are clean and dry, and approximately at the temperature of the location in which the unit is to be used. Do not touch the cable inserts or receptacles after they have been cleaned. Apply a liberal coating of vaseline to the cable inserts by means of a clean stick or cloth.
(13)	Remove the two corks from the transformer cable receptacles. Insert one end of each cable into a transformer receptacle, screw down the threaded cap tightly, and uncoil the cables. Place the cables over the support as shown in figures 1 and 2, and let the remaining cable inserts hang free.
Caution: Be certain the transformer is in the well of the carriage before mounting tube head.
(14)	To attach the tube head to the horizontal cross arm, loosen the thumbscrew on the tube hanger in order to allow the clamp to pass over the tapered retaining ring of the horizontal cross arm. Lift the tube head and hanger so that the mounting bearing of the hanger lines up with the projecting part of the horizontal cross arm. Push and rotate the mounting bearing on the projecting part until the tube hanger is completely engaged. Screw down the thumbscrew until the clamp is pulled down over the tapered retaining ring and tube head is secure.
(15)	The tube ends of the cables may now be pushed into the tube cable receptacles and threaded down tightly. Be sure that one cable connects the “anode” receptacle of the transformer and the “anode” receptacle of the tube head. Note that the two shockproof cables are alike, and that the two terminals of each cable are of the same construction.
(16)	Remove the control unit from the chest and place it in position on top of the transformer. (See figs. 1 and 2.) The rear terminal panel of the control should be facing the mast.
(17)	Secure the control unit to the transformer and chassis by means of the two guy retaining rods still attached to the chassis. Pass the short end of each rod under the control handle and engage the hook in the hole provided in the handle escutcheon. Engage the hooks of the long sections in the holes provided in the chassis. Pull down the catches of the retaining rods to clamp the control unit and transformer tightly to the base.
(18)	Use the two short web straps to fasten the cables to the rear of the control.
(19)	The long center strap is to be used for fixation of the horizontal cross arm or the mast while moving the unit between rooms.

(27)	The cone which may be attached to the tube head will be found mounted on the aluminum casting in the chassis and mast chest.
(28)	Aluminum filters and lead aperture plates for the tube head are found in the center compartment of the cable drawer.
b.	When X-ray field unit table unit is supplied. When assembling the X-ray field unit with table unit, set up the table with the L member in position for vertical chest roentgenography.
(1)	Assemble the rail sections to make three complete rails and place these rails, into the cut-outs of the table ends. Be sure that the rails extend into the recesses bored in the cut-outs and that the hinged plates are in the correct position; that is, the table end pillows (fig. 34, part 2) and the floor plates facing toward the center of the table. Tighten tie rods.
(2)	Raise the table ends and slide the detachable legs into position on the operating side of the table.
(3)	. Place the carriage (figs. 35, 36, and 37) on the top rails opposite the operating side, then lower the front of the carriage into position. Be sure that the pointer carriage lock screw (fig. 15, part 1) is loose so that the pointer lock casting clears the rail, that the lock for lengthwise carriage travel is in position, and that the bearing of the carriage support arm rests on the lower rail.
(4)	Tighten locks for lengthwise and crosswise carriage travel.

(7)	Secure the main vertical column by means of the hinged tube lock handle of the mast support.
(8)	Turn the short shaft crank, 9R05648 (fig. 38, part 18), so that the angulating housing cover is turned to the position shown in figure 38 and screw it on the flange of the L member. Unscrew the shutter rods cap from the L-shaped member.
(9)	Insert the L-shaped member assembly into the hole provided in the angulating housing and tighten the lock handle. (See fig. 39, part 3 and fig. 40, part 5.)
(10)	After the X-ray field unit is unpacked as discussed in paragraph 9a, c, and d, section V, position transformer chest in a convenient place on the operating side of the table.
(11)	Release and fold back the cover of the transformer chest.
(12)	To attach the tube head to the end of the L member, loosen the thumbscrew on the tube hanger and allow the clamp to pass easily over the flange of the L member. Lift the tube head and hanger so that the mounting bearing of the hanger lines up with the flange of the L member. Push and rotate the mounting bearing on the flange until the tube hanger is completely engaged. Screw down the thumbscrew until the clamp is pulled down over the tapered retaining ring and the tube head is secure.
(13)	Carefully remove the cables, one at a time, from the shipping drawer. Be sure that the four inserts as well as the four cable receptacles are clean, dry, and approximately at the temperature of the location in which the unit is to be used. Do not touch the cable inserts and receptacles after they are cleaned. Apply a liberal coating of vaseline to the cable inserts by means of a clean stick or cloth.
(14)	Remove the two corks from the transformer cable receptacles, insert one end of each cable into transformer receptacle, screw down the threaded caps tightly, and uncoil the cables. Place the cables over the L member and insert the cable inserts into the tube cable receptacles and screw down the threaded caps tightly. Be sure that one cable connects to the “anode” receptacle of the transformer and the “anode” receptacle of the tube head, and the other to the “cathode” receptacle of the transformer and the “cathode” receptacle of the tube head. Note that the two shockproof cables are alike, and that the two cable inserts of each cable are of the same construction.

11. Adjustments
a. X-ray field unit, machine, X-RAY. (1) Safety precaution. When operating the X-ray field unit, 9608510 on a 205-250-volt line, be sure to use 15 ampere fuses. Check fuses by removing the front terminal panel cover. When operating X-ray field unit 9608510 or 9608508 on 100-130-volt line, use 30-ampere fuses if the unit is operated up to 30 ma.
(2) Zero adjustment for meters. In order to obtain a true reading, the indicators of both meters must come to rest on the line to the extreme left of the scale. If they do not, remove the knurled nuts retaining the meter light cover. Using a small screw driver, turn the small adjusting screw visible in the center until the pointer comes to rest in the proper position. Replace the meter light cover.
(3) Line adjustment, (aj Turn the main switch of the control unit to the “off” position.
(^) Turn all controls to the lowest possible settings.
(c) Connect the male plug of the line cable to a community source, after noting the following line specifications: X-ray field unit, 9608508 requires 100-130-volt, 60-cycle, a-c. The X-ray field unit, 9608510 may be used within a line range of 100-130-volt, 205-250-volt, 50- or 60-cycle, a-c.
{dj If a voltmeter is available determine the line voltage.
(e) Remove the front terminal panel cover.
(/) Set the line adjuster strap of the front terminal panel of the control unit (figs. 53 and 54) on the tap most nearly corresponding to the line voltage. For example, if the line voltage measures between 100-108 volts, the line adjuster should be set on 104, between 108 and 116, set strap on 112, etc. In case a voltmeter is not available, determine the line voltage by using the kilovolt meter of the control unit.
(^) Set the major selector (C) to 6, and the minor selector (D) to 4. If the line adjustor strap is properly set, the kilovoltmeter will indicate 70. If the meter reads more than 70, set the line adjuster strap to a higher numbered tap until the meter indicates between 69 and 71. If the meter reads lower than 70, position the line adjuster strap to a lower numbered tap until the meter reads between 69 and 71.
Caution: When using an X-ray field unit generator as a source, always set the line adjuster strap on the 128 tap. Replace the front terminal panel cover.
(4) Circuit breaker adjustment, (a) Turn the main switch to the “on” position, adjust the major and minor kilovolt selectors until the kilovolt meter reads 70.
(/?) Turn the radiographic and fluoroscopic switch to radiography.
(r) Set the hand timer to 3 seconds.

Section VI. CONTROLS AND INSTRUMENTS
12. Controls on X-ray Field Unit, Machine, X-ray (fig. 56)
a Main switch. The main switch (fig. 57, part 9) is located at the top left ol the control panel. This switch serves to open and close both sides of the incoming line to the autotransformer. When the main switch is turned “on” the kilovolt meter should indicate, the pilot and meter lights should light, the X-ray filament should light, the X-ray tube blower should operate, and localizer lamps should light.
b. Radiographic and fluoroscopic switch. The radiographic and fluoroscopic switch (fig. 57, part 4) is located between the minor kilovolt selector and the milliamperage regulator (par. 12/) on the control panel. The radiographic and fluoroscopic switch is a deck switch. When the switch is set to the fluoroscopic side one deck of the switch selects the footswitch and disconnects the hand timer, the second deck selects below scale of the milliammeter and disconnects the high scale, and the third deck selects the limiting resistor for the filament circuit of the X-ray tube. When the switch is set to the radiographic side, the first deck selects the hand timer and disconnects the footswitch, the second deck selects the high scale of the milliammeter and disconnects the low scale, and the third deck shunts out the limiting resistor of the filament circuit. It should be noted that a red dot marks the radiographic position of the switch indicating caution in operation for this position.
c Kilovolt selector minor. The knob at the bottom center of the control panel is the control for the minor kilovolt selector (fig- 57, part 5). This control allows the kilovoltage to be varied in less than 1 kilovolt per step. The change in kilovolts will be noticed on the kilovolt meter above the control.
Caution: Do not move this control during an exposure since it may cause serious damage to the selector switch.
d Kilovolt selector major. The knob at the bottom left of the control panel is the control for the major kilovolt selector (See fig. 56.) This control allows the kilovoltage to be varied approximately 8 kilovolts per step. The change in kilovolts will be noticed on the kilovolt meter above the control.

i.	Footswitch. The footswitch (fig. 21, part 8) is plugged into the rear of the control unit by a four-prong plug. While in use it is placed near the operator, and while not in use it may be neatly arranged on the chassis base of the machine. The footswitch is used to control intermittent exposures for fluoroscopy. If plugged into the control unit it is automatically switched into the circuit when the radiographic and fluoroscopic switch is set for fluoroscopy.
13.	Instruments on X-ray Field Unit, Machine, X-ray
a.	Kilovolt meter. The kilovolt meter (fig. 56) is located on the left side of the control panel. It is a voltmeter placed in the primary circuit and is calibrated to read kilovolts. The meter used is of the “load on” type which indicates the kilovoltage when under exposure. If a presetting of this meter is desired, it will be necessary to determine what drop in meter reading is developed for each setting of milliamperage used. When the filament check switch is thrown upward, the filament current is indicated on the upper scale of this meter. This scale is printed in red figures and may be used as a basis for a filament chart to predetermine milliamperage values.
b.	Milliammeter. The milliammeter (fig. 56) is located on the right side of the control panel. The milliammeter indicates the amount of current passing through the X-ray tube. The meter has two scales. When the radiographic and fluoroscopic switch is in the radiographic position the 0-40 scale of the meter is used, but when the switch is moved to its fluoroscopic position the 0-8 scale is used. It should be especially noted that part of the scales of this meter are printed in red, indicating that operation is in the danger zone and the milliamperage should be lowered by adjusting the filament control counterclockwise. The milliammeter is provided with a meter light which is lighted by pressing and rotating the button at the bottom of the meter.
14.	Controls on X-ray Field Unit Table Unit
a.	Shutter knobs. The shutter knobs are located at the end of the screen arm where it joins the L member and angulating housing. There are two knobs, identified by their size. The small knob (9R05254) controls the shutters which adjusts the size of image crosswise on the screen, while the large knob (9R05256) controls the shutters which adjusts the size of image lengthwise on the screen.
b.	Vertical lock. The vertical lock (9R05216) is located at the rear of the carriage. This lock secures the vertical column when the table is in use. The crank controlling vertical movement should never be moved before first loosening the vertical lock.
c.	Rotation clamp and lock. The rotation clamp and lock (9R05202) is located on the angulating housing just below the large circular nameplate. (See fig. 59, part 2 and fig. 60.)

This lock secures the screen and tube in position while in use. The crank controlling rotation of the angulating housing should never be moved before this lock is released or injury to the equipment may result. The lock is secured after each adjustment of the tube and screen to hold them firmly in place.
d.	Short shaft crank. The crank with the short shaft (fig. 60, part 5) is used for controlling the rotation of the tube and screen. This crank is located on the upper section of the angulating housing and is identified by a nameplate marked “ROTATION”. The crank should never be moved unless the rotation lock is released.
e.	Long shaft crank. The crank with the long shaft (fig. 60, part 8) is used for controlling the vertical movement of the vertical column. It is located below the rotation crank and is identified by a nameplate marked “UP-DOWN.” Whenever it is desired to move the tube and screen vertically, this crank is used. It should never be moved unless the vertical lock is released.
f.	Carriage locks. The carriage is secured in place by two locks.
(1)	Carriage lock for lengthwise travel. The lock for lengthwise travel is located at the left front of the carriage. When the tube and screen are properly aligned lengthwise as compared to the table, this lock is fastened to retain proper alignment. The lock handle clamps the jaws of the lock to the table rail.
(2)	Carriage lock for crosswise travel. The lock for crosswise travel is located at the left top of the carriage. When tube and screen are properly aligned crosswise as compared to the table, this lock is secured to retain alignment. When lock handle is tightened the jaws of the lock clamp to the tie rod and hold the carriage secure against crosswise movement.
g.	Shutter lock. The shutter lock (fig. 46, part 1) is located on the shutter support and clamps to the L member. This lock secures the shutter assembly in place during fluoroscopic procedure and allows it to be moved out of the way for radiography. When the lock is loosened, the shutter assembly may be rotated and moved to a position from in front of the X-ray tube.
h.	Localizer scale adjustment. The knob for localizer scale adjustment is located at the right of the localizer scale. This knob allows movement of the scale to proper value in centimeters while localizing foreign bodies.

desired or in excess of 4 milliamperes, release the footswitch and turn filament control counterclockwise. If value is lower than desired, turn filament control clockwise. The footswitch must be depressed all the time during the treatment.
17.	X-ray Field Unit Table Unit (foreign body localization)
The focal distance checking gauge (fig. 19, part 10) is placed.on the fluoroscopic screen mounting. If the marks of the checking gauge do not coincide with the outside lines scribed on the fluoroscopic screen when exposed to X-ray, the focal screen distance is either too long or too short. The vertical lock should be released and crank controlling vertical movement adjusted so the lines coincide. The focal distance checking gauge should always be used to check the focal screen distance whenever the table unit is broken down and reassembled. To locate foreign body proceed as follows:
a.	Check fixation locks and align the focal spot with the center of the fluoroscopic screen.
b.	Align the foreign body with the central intersecting lines.
c.	Dampen skin marker pad, on the end of the depth marker with tincture of iodine or ink. Lower the depth marker until the pad rests on the skin, thereby marking it.
d.	Read the depth marker scale. The reading is the distance in centimeters between the screen and skin.
e.	Shift tube and screen so as to align the foreign body to either of the outer intersecting lines.
f.	Slide localizer scale and adjust pointer to the centimeter value read on the scale in step d. Clamp fixation of pointer to the side rail of table.
g.	Move X-ray tube and screen in the opposite direction until the same alignment on the foreign body is secured with the opposite outer intersecting lines.
h.	Read the localizer scale. The reading on the localizer scale is the depth in centimeters of the foreign body beneath the skin.
i.	To check the accuracy of the localization a test block, depth phantom (fig. 22, part 13) is supplied with the table unit and packed with the tools. It is made of wood and has lead numbers imbedded at 3 and 12 centimeters depth. Check to see if the depth measurements located with X-ray correspond with the actual location of the lead numbers. If the depths of the test numbers as read on the localizer scale do not conform to the actual depth of each number, the reading level on the depth marker scale must be adjusted so that it indicates correctly.

Section XIV. MAINTENANCE OPERATIONS
26.	To Check Source of Current
a.	If voltmeter is available it may be used to measure the voltage. This voltage must be within the range specified on the terminal panel of the control.
b.	If a voltmeter is not available, the source can be checked with a 110-volt lamp. If lamp illuminates naturally, the source is near 110-volt, but if lamp burns out, the source is 220-volt or higher. Do not connect machine to 220-volt source unless so specified on the control terminal panel.
c.	Be certain the supply is not d-c. This information should be available from the engineer servicing the area. Observe the line and if a pole transformer is located it is an a-c line.
27.	To Check and Replace Fuses
a.	To check the fuses located on the terminal board, connect a 110-volt lamp across the tops of the fuses. If the lamp does not illuminate, replace the fuses by removing them from their clamps, and either changing the fuse link or replacing the whole cartridge^
b.	If a voltmeter is available it may be placed across the tops of the fuses in the same manner to indicate presence of voltage. Proceed in the same manner as with the lamp.
28.	To Replace Line Plug
To replace the line plug, remove the old plug from the line. Next, pi epai e the tips of the conductors and place new insert in cover. The conductors should then be secured to the prongs and soldered^ (The new insert will be found in the spare parts cabinet under the control).
29.	To Check X-ray Filament
The X-ray filament can be checked by throwing the filament check switch to the “check filament” position, and if meter (G) swings off scale, it indicates the filament circuit is open.
30.	To Service Timer
Remove the back of the timer housing by taking out the three retaining screws, this will give access to the timer contacts. If contacts are burned and pitted, use crocus cloth to smooth them. Adjust by bending contacts so they will make good firm contact when the button is pressed.
31.	To Replace Toggle Mechanism in Foot Switch
Remove the floor plate and take out the old mechanism. Replace with new toggle mechanism being sure to have the conductors prop
88
erly connected to the switch. Be sure to replace the gasket, then reassemble floor plate.
32.	To Dress and Adjust Circuit Breaker Contacts
a.	Remove milliammeter for access to the contacts through meter port.
b.	If contacts are burned and pitted use crocus cloth to dress smooth.
c.	Contacts should be closed when knob is down, adjust by bending contact arm until good contact is established.
d.	Replace milliammeter as it was originally.
33.	To Check for Punctured High-tension Cables
This may be checked by first disconnecting one cable, and then the other to determine which cable caused the circuit breaker to kick out. If cable shows high-tension break-down by arcing or burning of rubber, it must be replaced with another cable.
34.	To Check for a Defective X-ray Tube
Disconnect the high-tension cables from the tube and operate the X-ray unit. If the circuit breaker does not kick out with the cables disconnected and kicks out when connected the trouble lies within the tube. If trouble is evidenced within the tube head it will be necessary to replace it with another as the tube must not be opened in the field.
35.	To Replace Meters
If meters are defective as indicated by operation or physical damage, they may be replaced.
a.	Remove the old meter, observing the connections as it is removed.
b.	Take new meter and make necessary connections. Note that each stud of the meter is marked to correspond with the lug marking for connection. Be certain that none of the lugs are touching, and that they have been properly made before reassembly.
c.	Replace one meter at a time so it will not be possible to interchange meters.
d.	If both meters are defective, in extreme emergency it may be necessary to operate the unit even though the meters ai e out. A shunt must be placed across the milliammeter before this can be accomplished. It would be well to record in some accessible place the setting of the major and minor kilovoltage selectors and the setting of the pointer of filament control for 5 milliamperes operation. The setting as recorded will only apply for one condition as sources of supply will vary. This operation should be limited to fluoroscopy only.
89
36.	To Adjust Chassis Brake
Remove rubber tip of the brake lever, loosen locknut and turn the adjusting screw clockwise. Do not adjust so tight that brake level-will not snap past the center.
37.	To Adjust Vertical Carriage of Tubestand if it Tends to Slip
Loosen the locknut of the adjusting screw beneath the handcrank and turn it clockwise. Be sure to retighten the locknut.
38.	To Adjust if Vertical Carriage Develops Excessive Play
Loosen the locknut of the fiber adjusting screws and adjust for correction. These fiber screws should not be tightened to a point of drag on the motion of the carriage.
39.	To Correct if X-ray Tube Tends to Rotate too Freely on its Axis
a.	The acorn cap nut located at the ring support should be loosened and the adjusting screws behind the cap nut should be tightened. Be certain to relock the cap nut.
b.	Check axis of tube to be certain that the ring supports are not riding on end covers of the X-ray tube.
40.	If Excessive Play Develops in Angulating Housing
a.	Loosen large hex nut located at the inside center of the angulating housing using the adjustable automobile wrench supplied with the table unit.
b With the 1 Winch socket wrench, also furnished, tighten head of bolt found above circular nameplate of the angulating housing just opposite the hex nut. Relock hex nut loosened in step a above.
c.	Loosen adjusting lever above the hex nut at the inside center of angulating housing and adjust proper meshing of gears. This can be determined by turning the. rotation crank and feeling the tension for turning. Relock adjusting lever.
d.	Remove nameplate from the top of the angulating housing and a setsci ew v ill become visible. Remove the setscrew and with Allen wrench tighten the adjusting screw to lower the worm gear so.it will mesh properly. Be sure to replace the setscrew after adjustment.
e.	Recheck all adjustments being sure they are tight.
41.	If Carriage Does Not Move Freely Along Full Length of Table
a. Be. certain the table rails and tie rods are properly assembled and are in the grooves provided in the table ends.
. b. Loosen the bolts holding the eccentric ball bearings and adjust the.carriage bearings until the carriage bears equal'weight on all bearings. Be sure to retighten the bolts holding the bearings.
90
c. If the surfaces of the table rails or bearings have become dirty or irregular, clean off all foreign material to ease operation.
42.	If Fluoroscopic Shutters Do Not Open to Give Full Coverage of Screen or Will Not Close to Give a Small Enough Aperture
a.	Remove the covering at the angle of the L member. This will give access to the joining of the shutter wires with the shutter rods. Adjust length of wires where connection is made to the rods so the shutters will completely close and may be opened to allow coverage of the entire fluoroscopic screen. Make certain all adjustments are tight before replacing the cover.
b.	The levers operating the shutters in the shutter housing should be cleaned and tightened for uniform movement. The aluminum filter on the bottom of the shutter housing must be i e-moved to reach the bottom shutter levers. The aluminum filter should be replaced as soon as the cleaning and tightening is finished. (See figs. 46, 47, and 61.)
43.	If Fluoroscopic Screen Assembly Will Not Hold Depth Marker in Place Two adjusting screws for adjustment of the friction on the depth marker is provided. These screws are located in the screen mounting beside the hole provided for the depth marker. By tightening these screws the depth marker will remain in place.

b. Procedure. (1) The adapter which holds the fork for the small wheels is assembled to the chassis base. This is secured in place by four SR00661 bolts using the holes from which the old caster and caster locks were taken. A SR00336 washer should be placed on the bolts and a SR00359 lock washer is used to hold the SR00526 hex nut secure. The small wheels, tires, and tubes, are assembled in the fork and this is placed in the holes provided in the adapter. The hex cap nuts that were taken from the old casters are used to secure the forks in place. The caster locks are placed in the holes provided in the adapter for locking the small wheels.
(2)	The base handle is now assembled to the adapter. This is held in place by two of the SR00661 bolts. The handle is located between the two small wheels. Use washers and nuts as in the case of the adapter bolts. The handle should be assembled before it is secured in place.
(3)	Brakes, large wheels, and axles are assembled to the base in the following manner: The brake assembly and the large wheels, with tires and tubes inflated, are placed together. With the flat plate surfaces of the brake assembly facing the chassis base, insert the axles through the wheel and brake assemblies which are mounted outside of the new type chassis base. The axles are secured in place by large hex nuts. Be certain all nuts are tight, and bolts are properly aligned.
(4)	Adjust the brakes by turning the brake adjusting screws that are found on the brake assembly between the large wheel and the chassis base. Adjust so the brakes just hold the unit in place when the brake is on.
