The reversing lever (B) is
used for withdrawing bits
from tight holes and
removing screws. It is
located above the trigger
switch. To reverse the
motor, release the trigger
switch FIRST and then push
the lever to the right. After
any reversing operations,
return lever to forward
position.
The locking feature (C) is for
use when the drill is mounted in a drill stand or otherwise firmly held...
NOT BY HAND.
Do not lock the switch "ON" when drilling by hand so that you can
instantly release the trigger switch if the bit binds in the hole.
Be sure to release the switch locking button before disconnecting
the plug from the power supply. Failure to do so will cause the tool
to start immediately the next time it is plugged in. Damage or injury
could result.
Chuck
To insert bit, open chuck jaws by turning collar with fingers and insert
shank of bit about 3/4" (19 mm) into chuck. Tighten chuck collar
by hand. Place chuck key in each of the three holes and tighten in
clockwise direction. It's important to tighten chuck with all three holes.
To release bit, turn chuck key counterclockwise in just one hole, then
loosen the chuck by hand.

OPERATION
WARNING: Always observe the safety instructions and applicable
regulations.
WARNING: To reduce the risk of injury, turn unit off and
disconnect tool from power source before installing and
removing accessories, before making any adjustments or
removing/installing attachments or accessories. An accidental
start-up can cause injury.
Drilling
1. 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. For MASONRY, such as brick,
cement, cinder block etc., use carbide-tipped bits.
2. Be sure the material to be drilled is anchored or clamped firmly.
If drilling thin material, use a wood "back-up" block to prevent
damage to the material.
