GREASE JOINT REJUVENATOR
®
#GFC2A
INSTRUCTIONS
The Grease Joint Rejuvenator
®
allows a clogged grease tting
or joint to take on fresh grease by injecting light penetrating oil
into the grease joint via the grease tting, thus breaking up and
removing any dirt, rust or debris. The purpose of this tool is to free
up the joint and tting, enabling them to be greased.
SET UP: First remove the piston from the tool body and ll with
non-chlorinated, non-aerosol, penetrating oil. Once the tool body
has been lled, 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 lling the tool body with light oil, put the
piston back and turn the tool upside down to allow the air bubble
to oat 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 uid.
(WEAR SAFETY GLASSES!)
USING THE TOOL: Once the air has been bleed from the tool,
you are now ready to unclog a stuck tting or joint. If using the
Professional Model, push the Grease Coupler over the grease
tting 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 tting and hold the tool down rmly. (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 tting or damage the tool. If you nd a stubborn
tting, try loosening the grease tting 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 difcult to remove from a tting. Unscrew the head
a quarter turn to loosen the jaws holding the tting. 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 ex hose, remove the female grease tting coupler from the
Professional Model #GFC2A. Use sealant tape and install the ex
hose into the tool body, then install the grease coupler on the end
of the hose. This gives you exibility 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.)
