Counter Dial
The counter dial can be set to limit the amount of
grease dispensed. Set the dial to ON to dispense
grease as long as the trigger is pulled. Set the dial
to "1" through "50" to dispense grease for a specifi c

Clearing Contamination
If the motor runs when the trigger is pulled, but there
is no pumping sound and grease is not dispensed,
there may be contamination in the grease gun.
Always make sure the barrel (inside and outside)
and surfaces contacting the barrel are clean of dirt,
dust and debris. This debris can be pulled into the
grease gun and clog the valve.
To clear the contamination:
1. Check to be sure the tool is properly primed and
that there is suffi cient grease in the barrel.
If the problem persists...
2. Remove the hose assembly.
3. Pull and hold the trigger for up to 45 seconds. If
grease begins to pump out of the tool the debris
has been cleared. Reattach the hose assembly
and begin using the tool.
If the problem persists...
4. Remove the bolt from below the hose assembly.
5. Pull trigger for 15 seconds to clear the contami-
nation.
6. If a spring or ball are
expelled, wipe away
any contamination and
re-insert, as shown.
7. Reattach the bolt and
tighten securely.
8. Pull trigger for 30 sec-
onds.
9. Reattach the hose as-
sembly and begin us-
ing the tool.
Bulk Grease Loading
Bulk grease can be loaded 2 ways, using the barrel
for suction loading, or using a pump to load grease
through a coupler.
Suction Loading
1. Remove the battery pack.
2. Unscrew and remove the barrel.
3. Insert the open end of the barrel below the sur-
face of the bulk grease.
4. Pull back the rod, and push it sideways into the
retaining slot.
5. Remove the barrel from the bulk grease.
6. Wipe excess grease from the outside of the bar-
rel and screw it into the grease gun.
7. Release the rod from the retaining slot and press
it completely into the barrel.
8. Prime the grease gun according to "Priming the
Grease Gun"
