pressure from the internal spring. Be extremely
careful when removing either end of the barrel. Connections of the hose
must be secured tightly to avoid any oil leakage.
SPECIFICATIONS
Always before refilling make sure that the plunger
rod is completely outward and is in locked position
Always use safety goggles when using the grease
gun.
Excess grease if left on floor, tools or equipment can
create slippery surfaces.

ASSEMBLY INSTRUCTIONS
3
1. Assembly of rigid extension
Rigid extension can be used in easily accessible grease fittings and it also makes
greasing a one hand operation. Rigid extension has two threaded ends, one end
closer to the bend must be used to screw coupler & the other end must be screwed
with the gun head opening.
2. Removing empty cartridge
Remove any cartridge in the grease gun barrel prior to refilling. To check if a cartridge
is in the barrel, first compress the spring by pulling the plunger handle fully outward.
Remove the grease gun head by turning it counter clockwise. Release the plunger
rod from the notch and push it forward allowing the grease cartridge to come out.
3. Locking and unlocking the plunger rod
This gun incorporates a groove on its plunger rod just below the follower & a notch in
its end cap. Plunger rod can be locked in its extreme position by simply pushing the
groove inside the notch. To release the plunger rod simply pull out the rod from the
notch & slowly push the plunger rod inside.Ensure slow movement, as releasing the
plunger rod quickly with open barrel can cause accident.
4. Priming
Usually after loading, all grease equipment have some trapped air pockets in grease.
Trapped air causes zero or reduced grease discharge. Removing these air pockets
from grease is referred to as Priming or Air Bleeding. It is highly recommended to
prime the grease gun after every loading. If the grease gun has been in regular use,
priming can be done without having to remove the grease gun extension & coupler
from the grease gun head.

Remove the plastic cap
from the cartridge and
insert the open end of the
cartridge into the grease
gun barrel until the rim
of the pull-tab end meets
the rim of the barrel. Now
remove the pull-tab seal.
Screw back the grease
gun head tightly onto the
barrel.
Fill the barrel with grease
using a scoop. When the
barrel is completely lled
with grease, shake the
grease gun barrel to allow
the grease to settle down.
Then screw back the
grease gun head tightly
onto the barrel.
Start operating the transfer
pump, keeping your hand
on the grease gun, lightly
pushing it down onto the
ller pump.
Once the gun barrel is
lled, pumping would get
very hard. Stop now &

valve from the ller pump
line. Wipe the bulk loader
valve again.
prime the grease gun
1. Release and push the plunger rod 2-3 times inwards and simultaneous press
the manual air release valve present at the top of the grease gun head allowing
trapped air to escape.
2. Operate the gun, if the grease comes out smoothly from the coupler, then the
grease gun is primed. If not then repeat step 1-2.

Grease gun and extension should be kept clean and checked for damage before each
use.
Greasing a grease fitting / nipple

construction. The coupler jaws snaps on to a grease fitting and maintains a tight fit.
2. When connecting the coupler to the grease fitting, press the coupler straight onto
the grease fitting to form a snug fit. Start operating the grease gun with the coupler
as square to the grease fitting as possible.
3. Once greasing is completed, slightly tilt the coupler, twist and pull back. The tilt and
twist action will allow easy removal of the coupler from the grease fitting.
