3. Maintenance Instruction
1. Lubrication.
Proper lubrication is the owner's responsibility. Failure to lubricate the air tool properly will dramati-
cally shorten the lire of the tool and will void the warranty.
This drill requires lubrication before the initial use and before and after each additional use.
2. Drill requires lubrication throughout the life of the tool and must be lubricated in two separate
areas : the air motor and the scaling mechanism. Follow the outlined procedures.
3. Air Motor Lubrication.
The motor must be lubricated daily. An air motor cannot be oiled too often.
Disconnect the drill from the air supply before lubricating.
3.1. Disconnect the drill from the air supply.
3.2. Turn the drill upside down.
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 drill to the air supply and cover the exhaust port with a towel.
Run the drill 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. Drill mechanism lubrication.
The drill should be lubricated monthly.
Disconnect the drill from the air supply before lubricating.
5.1. Disconnect the drill from the air supply.
5.2. Remove the slotted screw Allen head screw from the oil porthole on the right side of the tool
that has "OIL" stamped.
5.3. Put three teaspoons of air tool oil in the oil porthole. Replace the screw.
5.4. Reconnect the air supply to the hammer and run for 20 to 30 seconds.
Lubricate the entire scaling mechanism by rotating the tool upside down and sideways while run-
ning 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 scaling mechanism chamber is all that is needed for proper
lubrication.
