ASSEMBLY AND ADJUSTMENTS
WARNING: Prior to assembly and adjustment, ALWAYS unplug
tool.
Forward/Reverse Lever (Fig. 1)
The forward/reverse lever (C) 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 (viewed when holding the drill in the
operating position).
After any reversing operations, return lever to forward position.
OPERATION
WARNING: Always observe the safety instructions and applicable
regulations.
WARNING: To reduce the risk of serious personal injury, turn
tool off and disconnect tool from power source before making
any adjustments or removing/installing attachments or
accessories.
WARNING: To reduce the risk of personal injury, ALWAYS
ensure workpiece is anchored or clamped firmly. If drilling thin
material, use a wood “back-up” block to prevent damage to the
material.
WARNING: Do not attempt to tighten or loosen drill bits (or any
other accessory) by gripping the front part of the chuck and turning
the tool on. Damage to the chuck and personal injury may occur.
Trigger Switch (Fig. 1)
To start the drill, depress the trigger switch; to stop the drill, release
the trigger switch.
NOTE: Use lower speeds for starting holes without a center punch,
drilling in metal or plastics, driving screws or drilling ceramics.
Higher speeds are better for drilling wood and composition boards
and using abrasive and polishing accessories.
VARIABLE SPEED
A variable speed trigger switch (A) permits speed control—the
farther the trigger is depressed, the higher the speed of the drill.
For continuous operation, press and hold the variable speed switch,
move the lock-on button (B) up, then release the switch.
To stop continuous operation, press the switch briefly and release
it. Always switch the tool off when work is finished and before
unplugging.

WARNING: To reduce the risk of
serious personal injury, ALWAYS hold
securely in anticipation of a sudden
reaction.
Proper hand position requires one hand under the the housing, with
the other hand on the main handle (G).
Drilling
