Grease or empty cartridge in the barrel is under pressure
from the internal spring. Be extremely careful when
removing either end of the barrel
Always use safety goggles when using the grease gun
Do not use gun extension for other applications or at
pressures above the rated pressure level
Excess grease if left on floor, tools or equipment can
create surfaces that become slippery
PREPARING TO LOAD YOUR GREASE GUN
1. 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 anticlockwise to remove any empty cartridge.
2. Locking the plunger rod
: This gun incorporates a groove in its plunger rod that must be aligned with a notch in the
end cap when locking the plunger rod. The plunger rod can simply be pushed out of this notch when releasing the
handle.
3. 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.
4. Flipping the Follower
: Flip Type Follower resembles a cup which opens toward the head assembly when the gun is
used with bulk lubricant. For flipping the direction of this follower, unscrew the End Cap from the grease gun barrel.
Pull on the plunger handle to extract the follower and spring from the barrel. Grasp follower between thumb and
forefinger. Flip the follower lip from the rear to front side for Suction Filling. Flip the follower lip from the front to rear
side to allow for Cartridge Filling. The gun comes pre-assembled with the follower direction for cartridge fill.
CARTRIDGE LOADING
SUCTION FILL
Remove the gun head by rotating it in anticlockwise direction. Flip the follower if needed, as shown in the above figure.
Pull the Plunger Rod Handle all the way back. Lock the
plunger rod with the end cap.
Insert the open end of the barrel about 2” into the grease
container.
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.
Slowly pull the plunger rod handle to draw in grease into
the empty barrel while pushing the barrel deeper into the
grease until the plunger rod is completely extended. Lock
the plunger rod with the end cap.
The grease gun barrel should now be filled with grease.
The outside surface may have a lot of grease stuck to it
and should be wiped clean for safety. Shake the grease
gun barrel to allow the grease to settle down.
PRIME THE GREASE GUN :
For model 15F197 with bleeder valve :
Screw the gun head tightly onto the barrel. The bleeder valve should be held open while moving the plunger rod back
and forth to force out any trapped air.
For model 15F198 & 15F199 without bleeder valve :
Screw back the grease gun head onto the barrel, making sure to tighten only half-way, leaving 2-3 turns before the
barrel is fully tightened against the gasket in the head. Release the plunger rod & move it back and forth to force out any
trapped air. Screw the gun head tightly onto the barrel.
Operate the lever handle several times to remove any last traces of air till the gun starts dispensing grease.
