OPERATION
Always check the direction of the rotation before use.
AUTOMATIC SHUT-OFF FEATURE
The automatic shut-off feature will shuts off power to the motor, after the motor has
been stalled while the tool is unable to drill or drive.
When automatic shut-off occurs, the variable speed switch must be fully released first,
and then operate the tool once again. If at the same time the tool has overheating
situation, which is caused by motor’s being severely loaded and stalled, operate the tool
once again after leaving it to take a rest of over five minutes.
OPERATION AS A DRILL
Rotate the Torque Adjustment Collar (see Fig. 2A) to the Drill Position. Install and
tighten the desired drill bit in the chuck. Select the desired speed/torque range using
the dual range gear shifter to match the speed and torque to the planned operation.
Follow these instructions for best results when drilling.
Drilling:
Use sharp drill bits only. For WOOD, use twist drill bits, spade bits, power auger bits,
or hole saws. For METAL, use high-speed steel twist drill bits, or hole saws. Be sure
that the material to be drilled is anchored or clamped firmly. If drilling thin material,
use a “back-up” block to limit damage to the material. Always apply pressure in a
straight line with the bit. Always use enough pressure to keep the drill biting, but do
not push too hard or you could stall the motor or break the bit.
