Air Motor Lubrication
To maintain the maximum performance of the air tool, it must be lubricated
each time it is used. Dust, dirt, rust and oil residue will build up inside the tool
and reduce the performance. An in-line oiler is recommended for proper
automatic tool lubrication (see Figure 1). If an in-line oiler is not available, the
tool can be lubricated manually through the inlet port (see Figure 4).
1.
Disconnect the air tool from the air supply.
2.
Turn the tool upside down and while depressing the trigger,
add 4-6 drops of air tool oil or SAE10 nondetergent oil into the air inlet.
NOTE:
Depressing the trigger helps circulate the oil in the air motor.
3.
Reconnect the tool to the air supply, cover the exhaust port end with a towel and run in forward and reverse
directions for approximately 30 seconds to remove excess oil.
NOTE: If the tool remains sluggish after it has been lubricated, the internal components may need to
be cleaned.
To Clean:
Disconnect the air tool from the air supply and pour or spray a generous amount of WD-40® into the air inlet
with the trigger depressed. Connect the tool to the air supply, cover the exhaust port end with a towel and run in
forward and reverse directions for approximately 30 seconds. Follow the air motor lubrication instructions above
after cleaning is completed to re-lubricate the tool.
After oiling or cleaning, cover the exhaust port with a towel and operate the tool for
a few seconds to safely remove the excess oil. Clean the handle and surface of the tool of any oil residue.
Failure to cover the exhaust port and clean the tool, can result in serious injury.
Note: Keep the towel
away from moving parts!
