5. Use a wrench to tighten high pressure hose to
the pump outlet.
6. Use a wrench to tighten the other end of the
hose to Z Swivel of grease control valve. Tighten
the outlet extension & coupler to the control valve
outlet. Use thread sealant on all connections to
ensure leak-proof working.
7. With the air supply
turned off, connect the
Air line into the air inlet
on the pump.
PUMP OPERATION
1. Partially open the on/off air valve ( It helps in
creating initial vacuum when filling a totally dry
pump ). Pump will start operating automatically
until it gets primed. Pump is said to be Primed
when grease is available at the pump outlet, mak-
ing the pump ready to use. Once primed, the air
motor will stop. Open the on/off air valve fully.
2. Hold the grease control valve near a container
& press the trigger. Pump will start operating with
continuous grease discharge as long as the trigger
is pressed. Release the trigger & this will stop the
pump. Check for any leaks from any of the connec-
tions & Tighten again if required.
3. Connect coupler fitted onto the control valve
extension with the grease nipple & press trigger.
Be careful not to over-lubricate as the pump will
keep dispensing grease as long as the trigger is
pressed. Once the trigger is released, pump will
stop dispensing grease & the air motor will stop.
4. When not in use & at the end of each day, air
supply to the pump must be switched off.
MAINTENANCE
Service Precautions
• Before performing any service operation, always
shut off the air supply and release the pressure
of the medium, i.e. let the grease out so that the
pressure decreases. When storing the pump as-
sembly without the bucket, cover the Filter Tube
(57) with Filter Cap (62).
• Be careful not to damage any parts when dis-
mantling. While removing shafts which do not
have key flats, wrap a thick piece of cloth around
the shaft before removing it with a Pipe wrench,
Polygrip wrench or the like. The easiest way to re-
move such a shaft is to grip it in a vice with alumin-
ium or copper jaws, clamp the shaft in a hand-drill
chuck and then turn the chuck by hand.
• Be careful when fitting O-rings and seals. Always
lubricate them with oil or grease before fitting.
They must never be threaded over sharp edges
when being fitted. Lubricate all moving parts with
oil or grease.
• When troubleshooting, be on a lookout for dirt
in valves / ball seats, scratches in sealing surfaces &
damaged O-rings / seals / gaskets.
PUMPING SECTION DISASSEMBLY & REASSEMBLY
1. Hold the complete pump assembly in a vice &
unscrew the Filter Tube (57). Prevent the Piston
Rod (55) from rotating by inserting a rod through
the side hole in Piston Rod. Remove the Nyloc Nut
(61) & Piston Washer (60).
2. Unscrew the Bottom Coupler (54) & remove
Slide Bush (53). Unscrew the Top Coupler (52) &
remove lower Steel Ball (47), Non Return Spring
(48), Valve (49) & both O Rings (50).
3. Unscrew the Barrel (63). Drive out the lower
Slotted Spring Pin (44) taking care not to bend the
Extension Rod (46).
4. Unscrew the Pump Cylinder (51) from Extension
Rod (46). Remove upper Steel Ball (47) & Non Re-
turn Spring (48).
5. Drive out the upper two Slotted Spring Pins (44),
unscrew the Extension Rod (46) and then Connec-
tor (45).
6. Assemble by following the steps 1-5 in reverse
order taking care of the points below:
· Pump Cylinder (51) has a pin-hole end that must
face upwards; towards Extension Rod (46).
· Slide Bush (53) has a slotted end that must always
face upwards; towards Top Coupler (52).
· When fitting Plunger Rod (9), Connecting Rod
(43) & Plunger Nut (7), apply locking fluid on the
threads.
· Replace Component No. 51, 52, 53 & 55 as a SET.
DRIVE SECTION DISASSEMBLY & REASSEMBLY
1. Remove Bend Pipe (1) by opening both the Cou-
pling Nuts (2). Remove both Sealing Rings (3) &
unscrew both Bends (4).Unscrew the Cylinder
Cover (5) and Cylinder (10).
2. Unscrew Inlet Cover (32) & dismantle the two
Pushers (15) with their Pusher Springs (17), Pusher
Nuts (18) & Pusher Buttons (19).
3. Remove Circlip (20), both Filters (21), O Ring (22)
& Exhaust Valve (23).
