    DESCRIPTION
    GENERAL
    The Portable Signal Distortion Test Set, herein described, is a motor driven unit arranged to transmit normal or distorted signals for testing Teletype circuits and checking the efficiency of start-stop selectors on Teletype apparatus.
    The type of distortion set up may be marking or spacing bias, or marking or spacing end distortion.
    The test set is arranged to transmit continuously any one of four test signals; R, Y, SPACE, or a test message. Since it may be desired to use the test set with Creed apparatus, the test message is a 68 character line. The test set is equipped with a governed motor so that the normal speed of 368.1 O.P.M. may be changed to 404 O.P.M.
    The test set (Figure 1) consists essentially of an A.C. governed motor, a code disc transmitter, a distributor mechanism, and a panel equipped with control switches and local test jacks, all mounted on a base casting. The base is equipped with a power fuse, radio suppression filters, an output signal cord, a local test battery cord, and a power cord.
    115 volts A.C. (50 or 60 cycle) is required for operating the motor, and 115 volts D.C., for the operation of the local line circuits.
    DISTRIBUTOR TEST SIGNAL TRANSMISSION
    (A)	Code Disc Transmitter (Figure 2)
    The transmitter, which sets up combinations for transmitting the test message, consists principally of five code disc cams, contact levers, contact tongues, and contacts. The code disc cams actuate the contact levers which in turn position the contact tongues against their proper contacts.
    The code disc cam assembly is driven through a series of gears from the distributor shaft and is thus synchronized with the distributor brush arm.
    A friction assembly located at the end of the code disc cam assembly shaft (Figure 1), applies a drag on the shaft and prevents backlash.
    (B)	R, Y, and Space Selections (Figure 1)
    The repeated R, Y, and SPACE signals are obtained by electrically disconnecting the transmitting contacts and establishing, by means of the character control switch, the proper electrical circuit required for the transmission of the desired signal.
    DISTRIBUTOR (Figure 1)
    The distributor completes electrical connections between the transmitting contacts or the character control switch, and the signal line in the correct sequence and at the required speed. This is accomplished by brushes
    which are drawn across the commutator segments by the distributor brush arm attached to the distributor shaft. The brush arm mounts two sets of brushes: one pair of brushes makes contact with the inner solid collector ring and the. segments of the stationary ring; the other pair of brushes makes contact with the other solid collector ring and the segments of the outer movable ring. The latter brushes and rings only are used to transmit undistorted signals. Both sets of brushes and rings are used to transmit distorted signals by connecting electrically the corresponding segments of the movable ring and the stationary ring, either in series or in parallel.
    The outer segmented ring of the distributor is movable and is usually set to cause a 35% bias or end distortion of the transmitted signals; however, it may be adjusted to send any distortion from 0 to 50%. The amount of distortion is indicated on a scale at the side of the distributor disc.
    CONTROL SWITCHES (Figure 1)
    The distortion switch, motor switch (on and off), and character selecting switch are mounted on a panel above the motor.
    The distortion switch is used to select the type of distortion required and may be set at any of the following positions:
    (1)	BIAS M (Bias Marking), which advances the beginning of each marking impulse with respect to the character cycle. The segments of the commutator rings are connected in parallel.
    (2)	BIAS S (Bias-Spacing), which delays the beginning of each marking impulse. The segments of the commutator rings are connected in series.
    (3)	ZERO (no distortion), normal signal transmission.
    (4)	EDM (End Distortion-Marking), which delays the end of each marking impulse. One stop segment and the selecting segments are connected in parallel.
    (5)	EDS (End Distortion-Spacing), which advances the end of each marking impulse. The corresponding segments of both segmented rings are connected in series, and the two stop segments are connected in parallel.
    The character selecting switch is used to select the type of repeated signals to be transmitted, and may be set in any of the following positions:
    (1)	STOP, which short-circuits the signal line cord.
    (2)	TEST MSG. (Test Message), which sends the following 68 character sentence repeatedly:
    1
    THE QUICK BROWN FOX JUMPED OVER A LAZY DOG’S BACK 1234567890 TESTING
    followed by carriage return and line feed combination.
    (3)	RPT SP (Repeat Space), which sends repeated SPACE signals.
    (4)	R, which sends repeated R signals.
    (5)	Y, which sends repeated Y signals.
    RADIO FILTER CUTOUT SWITCH
    A toggle switch is provided in the left wall of the base casting to disconnect the radio filter from the signal line when checking the operation of the test set with a Teletype Signal Distortion Test Set with stroboscope (see Calibration Adjustment on page 6).
    ADJUSTMENTS
    GENERAL
    The following adjustments are arranged in a sequence that would be followed if a complete readjustment of the test set were undertaken. This fact should be kept in mind when a single adjustment is to be made because a change in one adjustment may affect other adjustments. If one adjustment is changed, related adjustments should be checked.
    The spring tension values given in this bulletin were derived from measurements made with Teletype spring scales. The scales are calibrated for use in a vertical 'pull” position. When used in any other position, the reading is an indicated value. Therefore in order to obtain the specified scale readings, the spring scales which are included in the Teletype parts bulletin tool list should be used. Springs which do not meet the requirements specified and for which no adjusting procedure is given, should be replaced with new springs. Ordering information may be obtained from the Teletype parts bulletin.
    Before proceeding to adjust, remove the chest cover. Then remove the test set from the base of the chest and remove the base plate.
    MAIN SHAFT POSITION ADJUSTMENT (Figure 3)
    The center of the main shaft bakelite gear should line up with the center of the motor shaft and pinion gear as gauged by eye. To adjust, position the main shaft by means of its upper and lower bearing cap mounting screws. Tighten the cap mounting screws.
    MOTOR POSITION ADJUSTMENT
    There should be a minimum amount of backlash between the motor pinion and the main shaft bakelite gear throughout a complete revolution of the main shaft (Figure 3). To adjust, loosen the motor mounting screws and position the motor. Tighten the screws.
    MOTOR ARMATURE THRUST SPRING COMPRES-
    SION (Figure 4)
    Apply the push end of a twelve pound scale horizontally against the governor outer contact disc and push
    toward the pinion end of the motor. It should require at least seven pounds to start to overcome the compression of the armature spring.
    REMOVE THE BRUSH SPRING PLATE AND GOVERNOR COVER
    REMOVE THE SPEED ADJUSTING SPRING
    Note.—Before making any adjustments, see "General,” on this page.
    GOVERNOR SHELL ADJUSTMENTS (Figure 5)
    (1) The governor contact points should meet squarely and there should be at least .010" clearance between the governor spring bracket and the rim of the governor shell. To adjust, remove the governor from its shaft and position the governor spring bracket by means of its mounting screws.
    Note.—If necessary, reposition the "fixed contact” bracket to facilitate squaring up the contacts.
    (2) There should be a gap of .015" to .040" between the governor contacts. To adjust, bend the governor contact spring.
    REPLACE THE SPEED ADJUSTMENT SPRING
    GOVERNOR SPEED ADJUSTING WHEEL FRICTION
    WASHER ADJUSTMENT (Figure 5)
    Turn the governor speed adjusting wheel to a point where the tension on the governor contacts is from 13 to 14 ozs. as measured by hooking a 32 oz. scale over the spring arm next to the contact and pulling parallel to the speed adjusting spring. Then insert a bank pin radially in the leather rim of the speed adjusting wheel. Hook a 32 oz. scale over the pin and pull at a tangent to the periphery of the adjusting wheel. It should require 16 to 20 ozs. to start the wheel moving. To adjust the friction, remove the friction washer and bend the large projections.
    GOVERNOR INNER AND OUTER DISC CONTACT
    SPRING ADJUSTMENT (Figure 6)
    The inner and outer disc contact springs should conform to the following requirements:
    2
    (1)	The distance from the inside surface of the governor cover to the highest point on the contact springs should be 25/32" to 27/32".
    (2)	Place a D (138-26) socket wrench over the nut located in the center of the governor cover that is used to hold the contact springs in place. With a 6" scale measure the radial distance from the vertical surface of the wrench to the point where the scale touches the curved surface of the inner disc contact spring. This distance should be 17/32" to 19/32'".
    (3)	In a similar manner measure the distance from the wrench to the point of contact on the outer disc contact spring. This distance should be 7/16" to l/2".
    To make the adjustments for the foregoing requirements, bend the inner and outer disc contact springs.
    Note.—Before making any adjustments, see "General,” page 2.
    REPLACE THE GOVERNOR COVER, TARGET, AND BRUSH SPRING PLATE
    GOVERNOR BRUSH SPRING PLATE BRACKET AD-
    JUSTMENT (Figure 4)
    The governor brush spring plate bracket should be positioned to meet the following requirements:
    (1)	A line through the center of the outer disc should also pass through the centers of both contact brushes.
    (2)	The surface of the brush spring plate bracket, on which the brush spring plate is mounted, should be in alignment with the outer surface of that part of the governor cover on which the target is mounted.
    (3)	The brush spring plate bracket should be parallel to the surface of the governor cover.
    To make the adjustments for the foregoing requirements, loosen the brush spring plate bracket mounting screws and position the bracket. Tighten the screws.
    GOVERNOR BRUSH SPRING PRESSURE ADJUST-
    MENT (Figure 4)
    (A)	Inner Disc Brush Spring
    Hook an 8 oz. scale over the inner spring just in front of the carbon contact brush. Pulling horizontally away from the motor, it should require 41/2 to 51/2 ozs. to start the brush moving away from the disc.
    (B)	Outer Disc Brush Spring
    Apply the push end of an 8 oz. scale against the outer brush spring just in front of the carbon contact brush. Pushing horizontally toward the motor, it should require 41/^ to 51/2 ozs. to start the brush moving away from the disc.
    To obtain the correct brush spring pressure, remove and bend the brush springs. When the springs are replaced and the spring pressure obtained, see that the
    contact brushes lie Hat against their respective discs and that the outer edges of the brushes are either flush with or not more than 3/64" inside the outer edges of the discs.
    Note. If necessary, level off the brushes by passing a piece of No. 0000 sandpaper between the brush and the disc.
    REMOVE THE INTERMEDIATE SHAFT GEAR GUARD
    INTERMEDIATE SHAFT END PLAY ADJUSTMENT
    (Figure 7)
    The intermediate shaft should have some end play, not more than .003". To adjust, unscrew the intermediate shaft collar set screws and position the collar. Tighten the set screws.
    Note. Before making any adjustments, see "General,” page 2.
    INTERMEDIATE SHAFT BAKELITE GEAR ADJUST-
    MENT (Figure 7)
    The center of the intermediate shaft bakelite gear should be in line with the center of the main shaft pinion gear as gauged by eye, and the play between the gears should be a minimum without bind throughout a complete revolution of the bakelite gear.
    To meet the foregoing requirements, proceed as follows :
    (1)	Loosen the intermediate shaft gear clamping screw and position the gear. Tighten the screw.
    (2)	Loosen the four mounting screws that fasten the code disc unit sub-base to the distributor base and position the assembly by means of its mounting screws. Tighten the mounting screws. Recheck adjustment (1).
    CODE DISC SHAFT END PLAY ADJUSTMENT (Figure 7)
    The code disc shaft should have some end play, not more than .006". To adjust, position the code disc assembly on its shaft by means of its mounting screw.
    CODE DISC SHAFT GEAR ADJUSTMENT (Figure 7)
    The code disc shaft gear should line up with the driving gear on the intermediate shaft as gauged by eye, and the play between the gears should be a minimum without bind throughout a complete revolution of the code disc shaft gear. To adjust, position the code disc bracket by means of its mounting screws.
    CONTACT BRACKET ASSEMBLY ADJUSTMENTS
    (Figure 8)
    Note.—To check these adjustments it will be necessary to remake them.
    (A)	Contact Lever Bracket Position Adjustment
    Loosen the contact screw set screws and back off the upper and lower contact screws all the way. With the
    3
    No. 1 and No. 5 contact levers resting on a high part of their respective code discs, there should be .020" to .030" clearance between the No. 1 and No. 5 upper contacts and their respective contact tongues. To adjust, position the contact lever bracket by means of its mounting screws.
    (B)	Contact Tongues Adjustment
    With all the contact levers on the low part of their respective code discs, contact tongues No. 2, No. 3 and No. 4 should line up with contact tongues No. 1 and No. 5 with a variation not to exceed .030". Adjust by bending the contact tongues.
    Note.—Before making any adjustments, see "General,” page 2.
    (C)	Contact Screws Adjustment
    With the No. 1 contact lever on the high part of its code disc, turn in the No. 1 upper contact screw so that it just makes contact with the No. 1 contact tongue, and then advance it 21/2 additional turns and tighten its set screw. Adjust the No. 1 lower contact screw so that there is a gap of .006'" to .010" between the tongue and the lower contact. Tighten the set screw. Adjust Nos. 2, 3, 4, and 5 upper and lower contact screws in the same manner.
    CONTACT LEVERS SPRING TENSION ADJUSTMENT
    (Figure 8)
    With the No. 1 contact lever resting on the low part of its code disc, hook an 8 oz. scale under the horizontal portion of the contact lever (the scale rod just clearing the contact tongue pivotal mounting) and pull vertically upward. It should require from 3 to 3% ozs. to separate the contacts. To adjust the No. 1 contact lever spring tension, position the spring anchor by means of its clamping screws. Use a test lamp to determine when the contacts break. Adjust Nos. 2, 3, 4, and 5 contact lever springs in the same manner.
    DISTRIBUTOR BRUSH ADJUSTMENT (Figure 9)
    Note.—If either of the brushes that ride on the two segmented rings is readjusted or replaced, the calibration adjustment on page 6 should be remade.
    Rotate the motor manually until the brush arm is parallel to the inscribed line on the commutator disc. Under this condition the trailing edge of the inner segment brush should make contact with its associated ring at a point in line (within .020") with the inscribed line on the stationary disc. All brushes should be centrally located with respect to their associated commutator rings. To adjust, loosen the brush spring damping screws and position the brushes. Tighten the clamping screws.
    DISTRIBUTOR BRUSH SPRING TENSION ADJUSTMENT (Figure 9)
    Caution.—Brush springs that are kinked or have sharp bends should not be used.
    Hook an 8 oz. scale under the end of each distributor brush spring and pull upward at right-angles to the end of the brush spring. It should require 21/2 to 31/^ ozs. to lift the brush from its commutator ring. To adjust, loosen the brush holder clamp screw so that the brush holder is friction tight and rotate the brush holder clockwise until the brushes rest against the segments with a pressure of 21/^ to 3^ ozs. Tighten the brush holder clamping screw.
    Note.—If it is found necessary to readjust the brush holder to obtain the proper spring tension, the brushes should be resurfaced in accordance with the following instructions.
    Place a piece of No. 0000 sandpaper (approximately 1" wide) face up on the distributor disc so that the brush will pass over the 1" width and draw the brushes across it two or three times or until the bottoms of the brushes are parallel to the surface of the segments. Recheck the spring tension and readjust if it does not meet the requirements.
    Note.—Before making any adjustments, see "General,” page 2.
    CODE DISC POSITION ADJUSTMENT
    Each lower (marking) contact should close before the distributor brush is within two segment lengths of the associated distributor segment and should remain closed until the brush has passed beyond the associated segment by two segment lengths. Use the inner stationary segmented ring when determining the adjustment. (See Figures 8 and 9 for location of parts.) To adjust, proceed as follows:
    Rotate the motor in its normal direction slowly by hand until the intermediate shaft bakelite gear clamping screw is accessible. Continue to rotate it slowly until the No. 3 marking (lower) contact just closes. Loosen the clamping screw and with the code disc held stationary, again rotate the motor until the brush riding on the inner segmented ring is within three segments plus or minus l/2 a segment length of the front end of the No. 3 segment. (l/2 segment length refers to the length of l/2 of any segment length except the stop segment.) Tighten the clamping screw on the intermediate shaft bakelite gear. Recheck the requirement for all contacts. Check the Code Disc Shaft End Play Adjustment on page 3.
    CODE DISC FRICTION ASSEMBLY TORQUE ADJUSTMENT
    With the motor running at least ten minutes hook a 32 oz. scale in the bottom of the slotted end of the fric
    4
    tion drag lever (next to the stop post) and pull up vertically. It should require 20 to 32 ozs. to start the arm moving away from the stop post. To adjust, loosen the lock nut on the end of the code disc shaft and regulate the tension by means of the capstan nut. Tighten the lock nut. (See Figure 7 for location of parts.)
    REPLACE THE INTERMEDIATE SHAFT GEAR GUARD DISTORTION SWITCH ADJUSTMENTS (Figure 10)
    Note.—Before making the following adjustments the switch knob and shaft detent cam should be positioned to meet the following requirements:
    (1)	The switch knob set screw should engage the flat side on the shaft, and there should be some clearance, not more than .025'" between the knob and the dial.
    (2)	The shaft detent cam set screw should engage the flat side on the small diameter end of the shaft, and the vertical position of the cam should be such that the detent lever roller rides centrally on the cam.
    Adjust by means of the set screws.
    DETENT ADJUSTMENT (Figure 10)
    With the detent roller in the center indent of the detent cam, the switch knob indicator should point to the center of the ZERO mark on the dial. To adjust, position the detent lever by means of its eccentric mounting screw.
    Note.—Before making any adjustments, see "General,” page 2.
    SWITCH CONTACT CAM ADJUSTMENT (Figure 10)
    The set screws of the switch contact cam should be at right-angles to the switch knob pointer and the heads of the set screws should be toward the left side of the unit when the switch knob is in the ZERO position. To adjust, position the cam by means of its set screws.
    SWITCH DETENT LEVER SPRING TENSION (Figure 10)
    With the detent lever roller in an indent on the cam, hook a 32 oz. scale over the roller and pull horizontally and at right-angles to the lever. It should require 22 to 30 ozs. to start the roller moving away from the cam.
    SWITCH CONTACT ASSEMBLY ADJUSTMENT
    (Figures 10 and 11)
    With the switch knob in the ZERO position, the contact pile-ups (numbered 1 to 8, from top to bottom) should be as follows:
    #	1—All Open
    #	2—All Open
    #	3—Open
    ^4—Back closed, front open
    d±5—Back closed, front open
    #6—Back closed, front open #7—Back closed, front open #8—Open
    (1)	With the switch knob at the ZERO position, the eight cam follower springs should bear against the cam. Holding the long contact springs (swingers) out of the way, hook an 8 oz. scale over the end of each cam follower spring at the cam and pull at right-angles to the spring. It should require some tension, not more than 1 oz. to start each spring moving away from the cam.
    (2)	Turn the knob to the EDM (End Distortion-Marking) position. The cam follower spring of the pile-ups #3 to ^:8 inclusive should assume the same position (within .010") as in the ZERO position. If necessary, refine the Switch Contact Cam Adjustment on page 10. Turn the knob to the BIAS S (Bias Spacing) position and check the cam follower springs of contacts ^1 and d+2 for the same requirements.
    (3)	With the switch knob in the ZERO position, the long contact springs (swingers) should bear against the cam follower spring or the next inner long contact spring (swinger). The short contact springs and the outer long contact springs (swingers) should be held out of the way while measuring the pressure of the inner long contact springs. The short contact springs should be held out of the way while measuring the pressure of the outer long contact springs (swingers) of pile-ups 4£5 and ^76. Hook an 8 oz. scale over the end of the long contact springs (swingers) and pull at right-angles to the springs. It should require ll/2 to 3 ozs. to start the springs moving. Adjust by bending the springs.
    Note.—Before making any adjustments, see "General,” page 2.
    Note.—For the following requirements, (4) and (5), refer also to the contact list on this page.
    (4)	Turn the switch knob to the EDS (End Distortion-Spacing) position. The contacts which were closed (when the switch knob was in the ZERO position) should now have a gap of .015" to .025". Adjust by bending the short contact springs.
    (5)	Turn the switch knob to the ZERO position. The contacts which are now open should have a contact gap of .015" to .025". Adjust by bending the short contact springs.
    (6)	With the switch knob in the ZERO position, the swinger spring studs of pile-ups #4 to #7 inclusive may not normally rest against the preceding swinger or cam follower springs. This is permissible if the requirements of (2) and (3) are met.
    MOTOR SPEED ADJUSTMENT
    The speed of the governed motor is checked by viewing the ten spot target on the motor governor through
    5
    the vibrating shutters of a speed indicator (tuning fork). In checking the speed of 368.1 O.P.M., an 87.6 V.P.S. fork should be used; and for the speed of 404 O.P.M., a 96.19 V.P.S. fork. The target is visible through a door on the switch mounting panel.
    With the motor running and the target lamp turned on, tap the speed indicator lightly to make it vibrate and hold it so that the shutters are close to the eye. If the motor is running at the correct speed, the target will appear stationary. If the motor speed is too fast, the target will appear to be moving in the direction of rotation; and if too slow, in the opposite direction.
    Note.—There is a possibility of setting the speed incorrectly, due to getting a speed multiple; i.e., the speed could be half or two-thirds the desired speed, or some other multiple, even though the spots appear to be stationary when viewed through the speed indicator shutters. This should be kept in mind if trouble is experienced in the operation of the unit.
    To adjust the speed, stop the motor, and turn the governor adjusting wheel in one direction or the other. Check the speed after each adjustment until the correct speed is obtained. Replace the chest cover.
    CALIBRATION ADJUSTMENT
    (1)	Connect the local test circuit plug to 115 volts D.C.
    (2)	Insert the signal line plug into one of the local test jacks.
    (3)	Plug an ammeter that will register approximately .060 amperes into the other local test jack. (Any device that will indicate when the circuit opens and closes, such as a Teletype unit with receiving magnets and armature, may be used.)
    Note.—Before making any adjustments, see "General,” page 2.
    (4)	Turn the character selecting switch to the Y position.
    (5)	Loosen the adjustable distributor disc clamping screws and rotate the disc clockwise until the pointer is off the calibration scale.
    (6)	Place the distortion switch in the EDM (End Distortion-Marking) position and rotate the motor shaft slowly in the normal direction until the brush arm approaches the beginning of the No. 5 segment of the stationary disc. Continue slowly to rotate the motor shaft until the ammeter just registers current. Allow the brush arm to remain in this position and turn the distortion switch to the BIAS S (Bias-Spacing) position. The ammeter should now register no current. Now
    rotate the adjustable distributor disc ring slowly counterclockwise until the ammeter again just registers current. Clamp the adjustable disc ring in this position by means of the three ring clamping screws. Then adjust the position of the indicator by means of its mounting screws, to register 0 on the calibration scale. Tighten the indicator mounting screws.
    After the disc and indicator have been adjusted according to the foregoing instructions, the disc is usually set for 35% bias or end distortion; however, it may be adjusted for any value from 0 to 50%.
    A Teletype Signal Distortion Test Set with stroboscope may be used to check various operations of the test set. However, an accurate check of the calibration adjustment cannot be made due to variation in speed caused by the governed motor of the test set. These speed variations will cause a wavering of the impulse as viewed on the stroboscope, making it very difficult to measure accurately the impulse length.
    Note.—The radio filter cut-out switch should be placed in the OUT position during the time that the test set is being checked by a Teletype Signal Distortion Test Set with stroboscope, to prevent signal distortion in the form of a "tailing” effect as viewed on the stroboscope.
    LUBRICATION
    The oil and grease specified in the supplement furnished with this bulletin should be used to lubricate the test set.
    Unless otherwise specified, one or two drops of oil at each of the places indicated will be sufficient. Use oil for lubrication at all places listed below except where the use of grease is specified.
    Friction Assembly Felt Washers—Saturate.
    Main Shaft—At bearings.
    Code Disc Shaft—At bearings.

    88970 1 Qt. of KS-7470 Oil
    88971 1 Gal. of KS-7470 Oil
    88973 1 Lb. of KS-7471 Grease
    88975 KS-8319 Grease Gun
    97116 4-oz. Tube of KS-7471 Grease
    The above grease is recommended instead of oil for lubricating motors equipped with ball bearings. The 88975 grease gun should be used for injecting grease into the bearings of Teletype ball bearing motors. The gun may be used also for applying grease to other parts of the apparatus and no other grease container need be carried. If this grease gun is not available, the oil listed in the foregoing should be substituted for lubricating ball bearing motors.
    Instructions for Filling the Grease Gun
    1.	Unscrew the lubricant tube from the cap casting of the grease gun.
    2.	Insert fresh lubricant through the open end of the tube with the fingers. Apply gradually to eliminate air pockets.
    3.	Tamp the lubricant down solidly in the tube by pounding the closed end solidly against the palm of the hand. Continue to add lubricant until the tube is completely filled and the metal follower rests against the perforated tube cover.
    4.	Fill the cap casting with lubricant flush to the bottom side of the tube threads.
    5.	Screw the lubricant tube into the cap casting part way only. Then insert a pencil or rod through the
    perforated tube cover and exert pressure against the metal follower so as the expel any entrapped air past the tube threads. When lubricant begins to ooze through the threads, tighten the lubricant tube securely in the cap casting.
    6.	Operate the handle back and forth for several strokes or until lubricant is pumped from the nozzle. The gun is then ready for use. If the lubricant does not flow from the nozzle in a solid stream, it is an indication that all air has not been expelled from the lubricant tube. Invert the gun and pound the cap casting end against the palm of the hand to jar the lubricant into the pump cylinder.
    Instructions for Lubricating Motor Ball Bearings
    The motor bearings are packed with grease before the motor leaves the factory and under ordinary operating conditions need no additional lubrication for approximately two months. At the regular lubricating intervals one or two strokes of the plunger of the gun should apply sufficient grease to each bearing. To lubricate, press the nozzle of the gun against the ball oiler and force the grease into the hole by pushing on the plunger of the gun. Care should be taken that the bearings are not overloaded. Overloading will result in the grease oozing out of the end castings and being forced into the motor or being thrown on other parts of the mechanism. After lubricating, the motor should be run for a few minutes and then any excess grease that has been forced out of the ends of the castings should be wiped off. Each time that the gun is used for lubricating a motor bearing, the plunger should first be depressed slightly to make sure that grease will be delivered.
