NOTE: When you operate the tool in counter-
clockwise rotation, the switch trigger is pulled
only halfway and the tool runs at half speed. For
counterclockwise rotation, you cannot push in
the lock button.
ON/OFF SWITCH AND LOCK-ON BUTTON
TO START THE DRILL:
1. To turn the tool "ON", depress the trigger
switch. Increased pressure increases the speed.
2. To turn the tool "OFF", release the trigger
switch.
CAUTION: Allow the motor to come to a
complete stop before setting the drill down.
LOCK-ON FOR CONTINUOUS OPERATION:
The trigger switch is equipped with a lock-on
button.
1. To activate the lock-on feature, squeeze the
trigger switch to turn the tool "ON", and then
depress the lock-on button. The trigger switch
is locked "ON".
2. To disable the lock-on button and turn the
tool OFF, squeeze the trigger switch again. The
lock-on button will disengage. Release the trig-
ger switch to turn the tool "OFF".
FUNCTION SELECTOR

OPERATION INSTRUCTIONS
DRILLING OPERATION
Hold the drill comfortably, with your finger
on the trigger switch. Use the auxiliary handle
whenever possible in order to gain extra control
and to prevent fatigue.
NOTE:
• Use sharp drill bits only.
• For wood, use twist-drill bits, spade bits, pow-
er-auger bits, or hole saws.
• For metal, use high-speed, steel-twist drill bits
or hole saws.
• For masonry (brick, cement, cinder block, etc.)
use carbide-tipped drill bits.
• Be sure that the material to be drilled is an-
chored or clamped firmly.

• If drilling thin material, use a "back-up" block
in order to prevent damage to the material.
TO BEGIN DRILLING
1. When starting a hole, make a mark on the
surface of the workpiece, and then drill a small
hole.
2. Hold the drill firmly with both hands.
3. Depress the trigger switch to start the drill,
gradually increasing speed. For continuous or
extended operation, hold the lock-On button
while pulling the trigger switch.
4. Apply pressure in line with the bit. Use
enough pressure to keep the drill biting, but do
not push hard enough to stall the motor.
NOTE: If the drill begins to stall, reduce pressure
slightly in order to allow the bit to regain speed.
If the bit binds, reverse the motor to free the bit
from the workpiece.
5. After completing the drilling operation, re-
lease the trigger switch, and allow the bit to
come to a complete stop before setting the drill
down.
6. When work has been completed, clean the
drill in order to allow for smooth operation of
the drill over time.
WARNING: To reduce the risk of injury, never
touch the bit in order to clean the debris until
the drill has stopped rotating and the bit has
cooled down.
DRILLING IN VARIOUS MATERIALS
1. Choose the hammer-drilling function when
drilling in hard masonry (concrete, hard brick,
stone, cement, or marble).
2. Choose the drilling function when drilling in
soft masonry (tile, flooring, soft brick, lime ce-
ment, or cinder block),.
3. When drilling in a smooth surface, attach ad-
hesive paper at the drilling location in order to
prevent the bit from gliding.
DRILLING IN WOOD AND PLASTIC
1. Start the drill slowly, and increase speed
gradually.
2. When using twist drill bits, pull the bit out of
the hole frequently in order to clear chips from
the bit flutes.
3. Use low speeds for plastic that has a low melt-
ing point.
DRILLING IN METAL
1. Lubricate drill bits with cutting oil when drill-
ing in iron or steel.
2. Do not use a lubricant when drilling in nonfer-
rous metals, such as copper, brass or aluminium.
