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 3).
1. Disconnect the air tool from the air supply.
Figure 3
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 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!
Lubricate Impact Mechanism
Periodically, the impact mechanism and the front bearing needs to be lubricated. (Lubricate 3-4 times a year for
general tool usage and more frequently with heavier tool usage).
1. Disconnect the air tool from the air supply.
Figure 4
2. Remove the allen socket screw from the oil port hole located on the front
of the tool.
3. Add 1 tablespoon of air tool oil or SAE10 nondetergent oil into the oil
port hole. Replace the allen socket screw (see Figure 4).
4. Reconnect the tool to the air supply and run for approximately 30 seconds,
rotating the tool sideways and upside down to lubricate all internal parts.
5. Disconnect the air tool from the air supply and remove the allen socket
screw. Hold the oil port hole over a suitable container to allow excess oil to drain.
6. Repeat the procedure above until the oil comes out clear. Any remaining oil inside the tool will properly
lubricate the tool.
7. Remember to replace the allen socket screw when lubrication is completed.
NOTES:
This lubrication procedure will help reduce moisture, dust and dirt that gradually increases inside the impact
wrench during use and reduces performance levels.
USER-MAINTENANCE INSTRUCTIONS
TROUBLESHOOTING GUIDE
SYMPTOM
POSSIBLE CAUSE(S)
CORRECTIVE ACTION
Tool will not run or runs
slowly
Grit in tool; tool gummed up
No oil in tool
Low air pressure
Torque regulator at low setting.
Air hose leaks
Clean the air motor inside the tool with WD-40®
(see “user maintenance” section).
Add 4-6 drops of air tool oil into the air inlet of the
tool (see “user maintenance” section).
Adjust compressor regulator to 90 PSI.
Adjust torque regulator knob to a higher setting.
Tighten and seal hose fittings with Teflon® tape if
leaks are found.
