=== Installation ===

# Fill the drum with Grease leaving empty space of about 2” from the top rim. Shake the drum after it is filled to remove air pockets. Place the follower plate in the grease drum with the lift handle facing upwards. Push the follower plate down, until some grease is forced through the centre hole on the plate.
# Place the drum cover on the drum. Lift the pump assembly & slide the suction tube through the drum cover & centre hole in the follower plate.
# Push the pump assembly down till the bottom of the pump touches the base of the drum. Adjust the drum cover and tighten it with the thumb screws provided along with the drum cover.
# Tighten the drum cover with the pump suction tube with the help of thumb screws.
# Use a wrench to tighten high pressure hose to the pump outlet.
# 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.
# With the air supply turned off, connect the Air line into the air inlet on the pump.

=== Troubleshooting ===
{| class="wikitable"
|'''PROBLEM'''
|'''POSSIBLE CAUSE'''
|'''SOLUTION'''
|-
| rowspan="3" |

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 & manually force down the Follower Plate to remove air pockets
|-
|Dent in the Grease Bucket restricting movement of Follower Plate leading to formation of air pockets in the bucket and inefficient working
|Get the dent removed to ensure proper movement of Follower Plate
|-
| rowspan="3" |

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
|1.    Loosen both Screws & remove Clip. Check for any build-up edge on Clip & tighten it again. Make sure the movement of Nylon Slider is neither very loose nor very tight

2.    If needed, replace Nylon Slider. Also replace the Paper Seal, Seat, Slider Guide & Clip to ensure the best fitting
|-
|

Piston / Piston Rod / Plunger jammed.

'''NOTE'''

Especially check Extension Rod (46), Cylinder (51), Top Coupler (52), Slide Bush (53) & Piston Rod (55) as shown in PARTS DRAWING
|1.    Remove suction tube. Disconnect Air Motor Assembly from Pumping Section by removing the upper two Slotted Spring Pins (44) from Connector (45)

2.    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 Air Motor

for smooth movement

3.    After locating the faulty section, check the respective Piston / Plunger & the associated washers & seals for any overlap or wear & tear. Replace the defective parts from Repair Kit

4.    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 connections to ensure they are air tight. Use thread sealant

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
|1.    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

2.    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 discharge coupler
|Open the coupler, remove all foreign particles / chips &

reassemble properly
|-
|Clogging of Filter Tube (57)
|Open Filter Tube (57), clean it & reassemble it properly
