Grease or empty cartridge in the barrel is under
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.
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. Selection of rigid extension or flexible hose
Rigid extension can be used in easily accessible grease fittings and it also makes
greasing a one hand operation whereas the flexible hose is designed to access
inaccessible grease fittings, it requires two hands for its operation one to press the
trigger and the other hand to reach out for the grease fitting.
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.

Cartridge Loading Bulk Loading
Remove the gun head by rotating it in counter-clockwise direction.
Pull the Plunger Rod Handle all the way
back and lock it.
Fill the barrel with grease using a scoop
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.
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.
Prime the grease gun
Release the plunger rod while keeping head assembly open by 2 turns, move
plunger rod back and forth 2-3 times to force out any trapped air. Exert force on the
grease using the plunger handle till the grease oozes out of the head and barrel
interface. Tighten the head and start operating the lever handle of the gun. If the
grease comes out of the coupler smoothly, then the gun is primed. If not, repeat the
priming procedure.

Grease gun and extension/hose should be kept clean and checked for damage before
each use.
Greasing a grease fitting / nipple
1. The grease coupler provided at the end of the grease gun extension has a jaw type
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.
