INSTRUCTION MANUAL
S1840, REV D
Foot Operated
Grease Pump
FOP-10
High Pressure Portable Grease
Pump for quick eortless
greasing in everyday lubrication
such as greasing of excavators &
other earth moving equipment,
automotive & agricultural
equipment etc.
Hands free operation; pump
operates using the Foot Lever,
which greatly reduces eort &
allows high pressure greasing
with highest comfort
Can be operated by hand when
under low machinery
Economical, pump is operated
by a single person & uses low
cost bulk grease
Designed with all moving parts
submerged in the same grease
which needs to be pumped,
thereby staying lubricated at all
times
Moving parts create wave action
in grease, auto removing air
pockets & eliminating the use of
a follower plate
Pump is available in 2 variants:
a. With Pistol Handle
b. With Quick Dis-connect
Coupler
WETTED COMPONENTS
Steel, Nitrile Rubber, Zinc*
(*only in FOP-10Q)

The pump has a spring loaded wave action mechanism installed
at the bottom of the bucket.
Pressing the foot lever makes
the cylinder to move forward
leaving empty space behind
it. The grease due to its
weight fills this empty space
On releasing the foot lever,
the cylinder returns to its
original position pushing the
accumulated grease into a
hollow piston that throws the
grease from the pump outlet
into delivery hose

WORKING OF PUMP
PRIMING THE PUMP
While using it for the first time, the pump comes pre-primed.
But when the pump is refilled, It may required priming
Priming is getting the pump started by operating foot lever for
1-2 minutes until grease gets dispensed from the coupler
Always PRIME the pump when the pump is refilled with grease
PARTS LIST FOR ASSEMBLY
Note: When working in cold weather or using a thicker grease,
keep grease thin for easy workability in one of the following
ways:
• Mix some oil (SAE30) with grease. Bump the bucket to
remove any air pockets
• Heat grease bucket with a Barrel Warmer or Heating Jacket.
The temperature should be kept at 0 - 30°C (32 - 86°F)
GREASE FILLING
While filling grease for the first time:
• Do ensure that grease is well settled down
• Use steel plate or tap the bucket on the ground 5 to 6 times
to allow the grease to settle and drive out big air pockets
OPERATION & USE
Fill recommended grease grade into the pump bucket
Tap the bucket on a firm surface to push the grease to displace
air pockets trapped in the cavities in the base of the bucket
Operate the pump by pressing the foot lever a few times until
grease comes out
Now the pump is ready for dispensing
DISCONNECT COUPLER ENGAGEMENT & DISENGAGEMENT
(FOP/10Q)
To engage the coupler, simply press the thumb lever & slide the
coupler jaws onto the grease fitting
Once greasing is completed, disengage the coupler simply by
pressing the thumb lever again to disconnect coupler from the
grease fitting

PROBLEM CAUSE SOLUTION
Pump doesn’t dispense grease
Air pockets/trapped air inside grease Follow priming steps
Use of very thick grease mainly in winters Warm the grease bucket using heating jacket/ barrel warmer
Damage in the Piston Kit Send it back to Service centre
Grease leaking out through the locking
pins (25)
Locking pins(25) could be damaged Replace the locking pins (25) from the repair kit components
Locking pins (25) do not go inside, when the
lever is pressed
Spring (26) could be damaged Replace the spring (26) from the repair kit components
