IMPORTANT! Vibration may cause failure if a quick coupler is connected
directly to the air tool. To overcome this, connect a leader hose to the tool. A
quick coupler may then be used to connect the leader hose to the air line hose.
OPERATION
TOOL OPERATION
1.
Clean the air drill of packing grease before first use. See the Air Tool
Lubrication section for instructions.
2.
Install a drill bit into the chuck and hand-tighten. Make sure the bit's shaft
is straight. Tighten using the chuck key. Remove the chuck key.
3.
Connect the air drill to the end of the air hose.
4.
Set the compressor to the correct air pressure and flow (see Specifications).
Start the compressor.
5.
Push the lever (Fig. 1) behind the trigger upward to set
it in forward. Push down to set the drill in reverse.
6.
Test the drill under no load to confirm the bit is
installed correctly.
7.
Place the drill bit point onto the workpiece surface.
a.
Use a center punch to mark the spot to prevent
the drill bit from skittering across the surface.
b.
A larger drill bit may require a pilot hole. Use a
narrower bit to drill the pilot hole first, then
install the larger bit.
c.
Apply a drop of cutting oil to the drill bit and surface before drilling metal.
8.
Squeeze the trigger and lightly push the drill against the workpiece. Continue
to apply pressure until the proper depth is reached.
9.
Hold the trigger until the drill bit is removed from the hole, then release
the trigger.
10. Shut the compressor off once the task is completed. Squeeze the trigger to
release residual compressed air from the hose and tool. Disconnect the tool.
11.
Remove the bit and store both the bit and the drill.
PRESSURE DROP
Apply the air consumption and pressure rate numbers to the tool's air inlet, not
the compressor's outlet. Calculate the pressure drop for your air supply set-up
and increase the compressor outlet pressure to compensate. Make sure you do
not exceed the maximum pressure for any part of your air supply system.
Installing a pressure gauge at the tool inlet is the best way to measure the air
pressure and adjust the compressor's output.
