GrEaSE GUN
There are air pockets in the container
tube if the tool operates but grease will
not eject from spout . To remove air
pockets from the grease gun, follow
the outlined procedures .
1 . Unscrew the gun head 1 to 1-1/2
turns .
NOTE:
Warming the grease aids in
removing air pockets . Stand the gun in
an upright position to prevent air
pockets from forming in the middle of
the cartridge .
2 . Pull the plunger handle back and
release quickly . Repeat this step
several times .
3 . Push the plunger handle back into
the container tube and screw the
gun head and container tube back
together .
4 . Press the air vent several times to
relieve any air pockets near the top
of the container tube . When all of
the air is gone, grease will start to
seep out of the air vent valve .
Release all pres-
sure from the
system before attempting to install,
service, relocate or perform any
maintenance.
Disconnect the
grease gun from
the air supply before lubricating.
The piston must be lubricated
periodically . Proper lubrication extends
the life of the tool and creates a better
sealing action for the piston . Under
heavy usage, the piston should be
greased with bearing grease every four
months and for light usage only once a
year . To grease the piston, follow the
outlined procedures .
1 . Disconnect the air grease gun from
the air supply .
2 . Remove the four slotted screws on
the gun head and remove the
spring and the piston .
3 . Apply a film of bearing grease
around the exterior of the rubber
skirt of the piston and a thin film of
grease on the inside of the cylinder .
4 . Install the spring, piston and the
four slotted screws .
