ASSEMBLY
To reduce the risk of injury, always
WARNING
unplug tool before changing or
removing accessories. Only use accessories
specifically recommended for this tool. Others
may be hazardous.
To reduce the risk of injury, do not grasp the bit
while the chuck is rotating or while the bit is fall-
ing from the chuck.
Installing Bits into Keyless Chucks
These tools are equipped with a hand-tightening key-
less chuck. Always unplug the tool before installing
or removing bits.
1. To open the chuck jaws, turn
the sleeve counterclock-
wise.
When using drill bits, allow
the bit to strike the bottom
of the chuck. Center the bit
in the chuck jaws and lift it
about 1/16" off of the bottom.
When using screwdriver bits, insert the bit far
enough for the chuck jaws to grip the hex of the bit.
2. To close the chuck jaws, hold the collar while turn-
ing the sleeve clockwise. Tighten securely.
To reduce the risk of injury, wear
WARNING
safety goggles or glasses with side
shields.
Chuck Removal
This tool is equipped with a threaded spindle to hold
the chuck. Before removing the chuck, unplug the
tool and open the chuck jaws. A left-handed thread
screw is located inside the chuck to prevent the chuck
from loosening when the tool is operated in reverse
direction. Remove the screw by turning it clockwise.
To remove the chuck, hold the tool so that only the
side of the chuck rests firmly
and squarely on a solid work-
bench. Insert the chuck key
or a chuck remover bar in
one of the keyholes. Turn the
chuck so the key is at about
a 30° angle to the bench top
and strike the key sharply
with a hammer so the chuck
turns in a counterclockwise
direction (looking from the front of the tool). This
should loosen the chuck from the spindle which has
a right hand thread making it easy to remove the
chuck by hand.
NOTE: When replacing the chuck, always replace
the left hand thread screw in the chuck.

tool while the motor is running,
allow it to come to a full stop
before reversing.
To reduce the risk of injury, keep
WARNING
hands and cord away from the bit
and all moving parts.
High rotational force. To reduce the risk of injury,
always hold or brace securely.
Starting, Stopping and Controlling Speed
1. To start the tool, pull the trigger.
2. To stop the tool, release the trigger.
3. To vary the drilling speed, increase or decrease
pressure on the trigger. The further the trigger is
pulled, the greater the speed.
To reduce the risk of explosion,
WARNING
electric shock and property dam-
age, always check the work area for hidden pipes
and wires before drilling.
1. Before drilling, clamp the workpiece securely.
Use backing material to prevent damage to the
workpiece during breakthrough.
2. When starting a hole, place the drill bit on the work
surface and apply firm pressure.Begin drilling at a
slow speed, gradually increasing the speed.
3. Always 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.
4. Reduce pressure and ease the bit through the last
part of the hole. While the tool is still running, pull
the bit out of the hole to prevent jamming.
If the tool seems as if it is about to stall, maintain a
firm grip and reduce pressure slightly to allow the
bit to regain speed. If the tool does stall, release
the trigger immediately. Reverse the motor, remove
the bit from the work and start again. Do not pull the
trigger on and off in an attempt to start a stalled drill.
This can damage the drill.
APPLICATIONS
To reduce the risk of electric shock,
WARNING
check work area for hidden pipes
and wires before drilling or driving screws.
Selecting Bits
When selecting a bit, use the right type for your job.
For best performance, always use sharp bits.
Drilling in Wood, Composition
Material & Plastic
When drilling in wood, composition materials and
plastic, start the drill slowly, gradually increasing
speed as you drill. When using twist drill bits, pull
the bit out of the hole frequently to clear chips from
the bit flutes. Use low speeds for plastics with a low
melting point.
