3.3. Simultaneously (at the same time), pull the trigger and pour a teaspoon of oil in the air inlet.
Then, push the forward and reverse button in both directions.
After an air tool has been lubricated, oil will discharge through the exhaust port during the
first few seconds of operation. Thus, the exhaust port must be covered with a towel before
applying air pressure. Failure to cover the exhaust port can result in serious injury.
4. Connect the impact wrench to the air supply and cover the exhaust port with a towel (See Figure
1). Run the impact wrench in both the forward and reverse directions for 20 to 30 seconds. Oil will
discharge from the exhaust port when air pressure is applied.
5. Impact mechanism lubrication.
The impact wrench should be lubricated monthly.
Disconnect the impact wrench from the air supply before lubricating.
5.1. Disconnect the impact wrench from the air supply.
5.2. Remove the slotted screw or allen head screw from the oil port hole on the right side of the tool
that has "OIL" stamped on.
5.3. Put three teaspoons of air tool oil in the oil port hole. Replace the screw.
5.4. Reconnect the air supply to the impact wrench and run for 20 to 30 seconds.
Lubricate the entire impact mechanism by rotating the tool upside down and sideways while running
the tool.
5.5. Remove the screw and hold the oil port hole over a suitable container to allow excess oil to
drain.
5.6. If the oil is dirty, repeat the procedure above until the oil comes out clear. Install the screw and
tighten. The residual oil remaining in the impact mechanism chamber is all that is needed for proper
lubrication.
