OPERATING INSTRUCTIONS (CONTINUED)
Bulk-Filled Grease:
1. Unscrew the grease gun from the
container tube.
2. Insert open end of container tube in
to grease bucket (fully submerging
the opening).
3. Pull the plunger handle back to suck
grease in to the container tube. Pull
slowly and with consistent force to
ensure that the container tube is full
of grease by the time the plunger
handle is fully extended.
4. Thread the grease gun and container tube back together and turn until
tight.
5. Press the handle release tab down to activate the plunger handle rod
and push the plunger handle back into the container tube.
6. Press the air vent valve several times to relieve any air pockets near the
top of the container tube.
TIP: For best results, consider priming
grease gun before first use. To do this,
pack some grease in to the grease inlet
port of the gun, then operate as usual.
(See arrow in Figure 5.)
Connect grease gun to air compressor
system following Air Tool Set Up
Instructions (IN170102AV).
CARE & MAINTENANCE
Failure to lubricate and maintain your air tools properly will dramatically
shorten their life. Use “air tool” oil every time you use your grease gun to
lubricate, clean and inhibit rust in one step. Campbell Hausfeld sells air tool
oil under part number ST1270.
In addition to regular lubrication of your air tool, the grease gun piston must
be lubricated periodically. Under heavy usage, the piston should be greased
with bearing grease every four months. For light usage only once a year.
To grease the piston:
1. Disconnect the tool from the air supply.
2. Remove the 4 screws on the gun head.
3. Separate the gun head from the pistol grip and remove the spring and
the piston.
4. Apply a film of bearing grease around the exterior of the rubber skirt on
the piston and a thin film of grease on the inside of the cylinder.
5. Install the spring and piston and reassemble the gun head and the pistol
grip. Insert and tighten 4 screws.
