4. Unscrew the Plunger Nut (7) and remove Rub-
ber Plunger (8).
5. Unscrew Plunger Rod (9) from Connecting Rod
(43) and remove Slider (30). Remove Slider Guide
(38), its outer O Ring (37), Seals (39), Seal Support
(40) & its inside O Ring (11).
6. Open the two Screws (29) & remove Clip (28),
Nylon Slider (27), Slider Guide (26), Seat (25) &
Paper Seal (24).
7. For reassembly of Air Motor, follow the above-
mentioned steps 1-6 in reverse order taking care
of the points below:
· When fitting Pushers (15), open Inlet Cover (32) &
ensure correct installation of Pusher Buttons (19).
· Conical side of Seals (39) must face upwards. As-
semble Slider guide (38), its outer O Ring (37),
Seals (39), Seal Support (40) & its inside O Ring
(11). Hold them as a set & mount on Connecting
Rod (43).
TROUBLESHOOTING
PUMP OPERATES, BUT DOES NOT DISPENSE ANY
GREASE
Grease is too thick/too cold. Store grease in a
warm place.
Air pockets in grease. Shake the Grease Bucket
(64) & manually force down the Follower Plate
(65) to remove air pockets.
Dent in the Grease Bucket (64) restricting move-
ment of Follower Plate (65) leading to formation
of air pockets in the bucket and inefficient work-
ing. Get the dent removed to ensure proper move-
ment of Follower Plate (65).
PUMP NOT WORKING / LESS DISCHARGE
Inlet pressure is too less. Increase inlet pressure. It
must be at least 30 PSI (2 BAR).
Nylon Slider (27) is jammed / overtight.
· Loosen both Screws (29) & remove Clip (28) .
Check for any build-up edge on Clip (28) & tighten
it again. Make sure the movement of Nylon Slider
(27) is neither very loose nor very tight.
· If needed, replace Nylon Slider (27). Also replace
the Paper Seal (24), Seat (25), Slider Guide (26) &
Clip (28) to ensure the best fitting.
Piston / Piston Rod / Plunger jammed.
NOTE: Especially check Extension Rod (46), Cylin-
der (51), Top Coupler (52), Slide Bush (53) & Piston
Rod (55) as shown in PARTS DRAWING.
· Remove suction tube. Disconnect Air Motor As-
sembly from Pumping Section by removing the
upper two Slotted Spring Pins (44) from Connec-
tor (45).
· Supply input air to Air Motor. If it works properly
without the barrel assembly, then the problem lies
with the pumping section. Otherwise check the
10
Air Motor for smooth movement
· After locating the faulty section, check the re-
spective Piston / Plunger & the associated washers
& seals for any overlap or wear & tear. Replace the
defective parts from Repair Kit
· Ensure to replace the moving parts having close
tolerances (such as Piston & Cylinder alongwith
Non Return Springs & balls) as a SET to ensure the
best fitting.
PUMP CONTINUES TO OPERATE EVEN AFTER THE
TRIGGER OF GREASE CONTROL VALVE (69) HAS
BEEN RELEASED
Leakage in the assembly. Check all the connec-
tions to ensure they are air tight. Use thread seal-
ant. Check O rings & seals for damage. Replace the
defective parts from Repair Kit.
GREASE COMES THROUGH THE AIR EXHAUST
VALVE (23)
Grease leaks into the Air Motor. Check Slider
Guide (38), O Ring (37), lower O Ring (11), Seals
(39) & Seal Support (40) for wear & tear. Replace
the damaged parts from Repair Kit.
AIR PASSES DIRECTLY FROM INLET TO THE OUTLET
& PUMP DOES NOT WORK
Nylon Slider (27) is jammed / overtight.
· Loosen both Screws (29) & remove Clip (28) .
Check for any build-up edge on Clip (28) & tighten
it again. Make sure the movement of Nylon Slider
(27) is neither very loose nor very tight.
· If needed, replace Nylon Slider (27). Also replace
the Paper Seal (24), Seat (25), Slider Guide (26) &
Clip (28) to ensure the best fitting.
DISCHARGE SUDDENLY STOPPPED WHILE THE
PUMP WAS RUNNING
Seals/O-Rings Damage. Check all seals / O-Rings &
replace the damaged parts from Repair Kit.
Chip / Other foreign particles get clogged at dis-
charge coupler. Open the coupler, remove all for-
eign particles / chips & reassemble properly.
Clogging of Filter Tube (57). Open Filter Tube (57),
clean it & reassemble it properly.
