INSTRUCTIONS
GFC2A Grease Joint Revitalizer
The Grease Joint Rejuvenator® allows a clogged grease fitting or joint to take
on fresh grease by injecting light penetrating oil into the grease joint via
the grease fitting, thus breaking up and removing any dirt, rust or debris.
The purpose of this tool is to free up the joint and fitting, enabling them to
be greased.
SET UP: First remove the piston from the tool body and fill with non-
chlorinated, non-aerosol, penetrating oil. Once the tool body has been filled,
reinsert the piston, gently working it into the core of the body. Be sure to
clean the piston and O-Ring before inserting, as dirt makes the tool less
effective. NOTE: A spare O-Ring is located near the head of piston shaft and
serves as a marker to show when the tool body is empty. To get the best use
out of this tool, bleed all the air out of it. When the piston is inserted
into the tool body, air may get trapped inside. Any air left in the tool
reduces the hydraulic pressure causing the tool to be less effective. (If the
piston bounces back when tapped, it has air in it!)
REMOVE THE AIR: After filling the tool body with light oil, put the piston
back and turn the tool upside down to allow the air bubble to float to the
top. Place a rag over the end of the tool and tap on the piston lightly with
your hand until the air bubble burps out. You are now ready to use the tool.
When bleeding, be sure and keep your face and eyes away from expelling air and
fluid.
(WEAR SAFETY GLASSES!)
USING THE TOOL: Once the air has been bleed from the tool, you are now
ready to unclog a stuck fitting or joint. If using the Professional Model,
push the Grease Coupler over the grease fitting and tap the piston head with a
light hammer. It may take several taps, but the piston will eventually move
down into the tool body. This is the indication that the joint is being
opened.
Once the piston has pushed all the oil out, remove the tool and grease the
joint. (Note: some joints are more stubborn than others.
Several attempts with the Grease Joint Rejuvenator® may be necessary.) If
using the Pocket Model, gently place the open end over the grease fitting and
hold the tool down firmly. (The O-ring inside the end of the tool creates a
seal and keeps the oil from leaking out.)
PRECAUTIONS: Be sure NOT to hit the tool too hard as you can snap off a
grease fitting or damage the tool. If you find a stubborn fitting, try
loosening the grease fitting one or two turns to expel any trapped air and
increase the cleaning pressure. When the Grease Fitting Coupler on the end of
the Professional Model is new, it may be difficult to remove from a fitting.
Unscrew the head a quarter turn to loosen the jaws holding the fitting. The
jaws can be turned around for extra life. (Note: The jaws are a wearable
item and are not warranted.)
INSTALL AUXILIARY FLEX HOSE: Some applications may require the use of the
auxiliary hose to make a bend. To install the flex hose, remove the female
grease fitting coupler from the Professional Model #GFC2A. Use sealant tape
and install the flex hose into the tool body, then install the grease coupler
on the end of the hose. This gives you flexibility when trying to access tight
places. The use of the hose should only be temporary. The Grease Joint
Rejuvenator® works best without the hose. (Auxiliary hose can only be used
with the Professional Model.)
CLEANING: Keep unit dry and oiled. If unit rusts, use a light steel wool
and oil as soon as possible.
LIFETIME LIMITED WARRANTY: Workmanship and material. If you find a defect
in our material or workmanship, we will repair or replace the unit. It does
not cover use and abuse claims.
