FORWARD/REVERSE SWITCH.
The forward/reverse switch determines the
running direction of the tool.
1. To select "forward" motion, release the
trigger switch, and push the forward/reverse
switch to the right side of the tool.
2. To select "reverse" motion, release the
trigger switch, and push the forward/reverse
switch to the left side of the tool.
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 (1). Increased pressure increases the
speed.
2. To turn the tool
"OFF", release the
trigger switch (1).
CAUTION: Al-
low the motor to
come to a com-
plete 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 (1) to turn the tool "ON", and
then depress the lock-on button (2). The trig-
ger switch is locked "ON".
2. To disable the lock-on button and turn the
tool OFF, squeeze the trigger switch (1) again.
The lock-on button will disengage. Release the
trigger switch to turn the tool "OFF".

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,
power-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 pres-
sure 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,
release 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, ne-
ver 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
cement, or cinder block),.
3. When drilling in a smooth surface, attach
adhesive paper at the drilling location in order
to prevent the bit from gliding.
