If any air is leaking, turn off the compressor, disconnect the air hose, and repair

the leak. Repeat steps 3 and 4.

5.

Push in on the Supporter (45) and place the Drill Bit (46) over the spot weld to

be drilled and release the Supporter; then release Supporter (45).

The spot weld must be within two inches from the edge of the metal where the

spot weld is located. The two inch Arm (50) goes under the metal with the spot
weld.

6.

Grip the Air Drill firmly with both hands and press down on the Trigger (12).

Press the Trigger to the first click to operate the drill at low speed so you can

position the bit in place. Press it all the way in to drill.

Caution: If the Air Drill will not turn, or if it stalls while drilling, do not raise the
outlet pressure of the air compressor. Do not continue with attempts to drill
until the problem is resolved.

7.

Press down with steady, even pressure. Let the Drill Bit do the drilling.  While

drilling, turn the adjustment wheel to draw the Arm (50) and Bit (46) together.

8.

When the Supporter (45) will not allow the Drill Bit to continue further, the drilling

is complete.

If part of the spot weld remains, turn the Adjustment Wheel (29) to allow the Drill

Bit to drill deeper, and repeat steps 5 to 8.

9.

When finished drilling, turn the compressor off and remove the hose connection

to the Air Drill.

10. Press and hold in the Trigger (12) to release any air remaining in the Air Drill.

Maintenance

1.

After each use, wipe the Air Drill with a clean cloth to remove any dirt and
grease buildup.

2.

To maintain tool life, always lubricate the air line by adding a few drops of
pneumatic tool oil to the air line before each use. Or, install the automatic
oiler-filter system as illustrated on page 5.

3.

Before each use, drain water out of the air compressor tank and condensation
from the air lines. Refer to the Air Compressor Operator’s Manual.

Manual Tool  Lubrication

1.

Disconnect the Air Drill from the air supply and turn it so the Air Inlet fitting is
facing upward.

2.

Hold the Trigger (12) in and place one teaspoon of pneumatic tool oil into the air
inlet (use SAE #10 weight oil if air tool oil is not available). Holding the Trigger
lever in helps circulate the oil in the air motor.

3.

Connect the Air Drill to the air supply and cover the Muffler Cover (11) with a
towel.  Run for a few seconds. Excess oil with be blown out the Muffler (54).
