Air Motor and Drive End Lubrication
Air Motor:
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 3).
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 non-detergent oil into the air inlet.
NOTE:
Depressing the trigger helps circulate oil in the air motor.
Drive End:
To maintain the maximum performance of the air tool, it must be
lubricated each time it is used. The yoke and ratchet housing may get
Figure 4
hot if this area of the air tool is not lubricated during the use of the air
tool. The tool can be lubricated manually between the yoke and ratched
housing as shown (see Figure 4).
3. Position the drive end of the tool upwards and while depressing the
trigger, add 4-6 drops of air tool oil or SAE10 non-detergent oil
between the yoke and ratchet housing.
NOTE:
Depressing the
trigger helps circulate oil in the drive end area.
4. 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!

Adjust compressor regulator to 90 PSI.
Air hose leaks
Tighten and seal hose fittings with Teflon® tape if
leaks are found.
Drive end of the tool
