drastically reduce the tool life.
b. To tighten a fastener, turn the forward/reverse button to "F" (clockwise). Start the fastener by hand then
grip the ratchet wrench with your hand and place it on the fastener to be tightened. Gently squeeze the
trigger to tighten down the fastener. Drive the fastener until the ratchet stalls, release the trigger to stop
the tool, and then tighten further by operating the air ratchet wrench in the same manner as you would
operate a manually operated ratchet wrench.
NOTE: Do not use the air ratchet wrench to set torque. Always use a torque wrench to set
torque.
Disconnect the tool from the air supply before lubricating or changing sockets.
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 A). If an in-line oiler is not available, the tool can be lubricated manu-
ally through the inlet port (see Figure C).
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 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 for-
ward 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!
