OPERATION
KEYLESS CHUCK
See Figure 4.
The drill has a keyless chuck to tighten or release drill bits
in the chuck jaws. The arrows on the chuck indicate which
direction to rotate the chuck body in order to
LOCK (tighten)
or
UNLOCK (release) the drill bit.
WARNING:
Do not hold the chuck body with one hand and use
the power of the drill to tighten the chuck jaws on
the drill bit. The chuck body could slip in your hand,
or your hand could slip and come in contact with
the rotating drill bit. This could cause an accident
resulting in serious personal injury.

VARIABLE SPEED
The variable speed switch trigger delivers higher speed and
torque with increased trigger pressure and lower speed with
decreased trigger pressure.
NOTE: You might hear a whistling or ringing noise from the
switch during use. Do not be concerned; this is a normal
part of the switch function.
DIRECTION OF ROTATION SELECTOR
(FORWARD/REVERSE/CENTER LOCK)
See Figure 3.
The direction of bit rotation is reversible and is controlled
by a selector located above the switch trigger. With the drill
held in normal operating position, the direction of rotation
selector should be positioned to the left of the switch trigger
for drilling. The drilling direction is reversed when the selector
is to the right of the switch trigger.
Setting the switch trigger in the
OFF (center lock) position
helps reduce the possibility of accidental starting when not
in use.
CAUTION:
To prevent gear damage, always allow the chuck
to come to a complete stop before changing the
direction of rotation.
To stop the drill, release the switch trigger and allow the
chuck to come to a complete stop.
NOTE: The drill will not run unless the direction of rotation
selector is pushed fully to the left or right.
Avoid running the drill at low speeds for extended periods
of time. Running at low speeds under constant usage may
cause the drill to become overheated. If this occurs, cool the
drill by running it without a load and at full speed.
TWO-SPEED GEAR TRAIN
See Figure 5.
The drill has a two-speed gear train designed for drilling or
driving at
LO (1) or HI (2) speeds. A slide switch is located on
top of the drill to select either
LO (1) or HI (2) speed. When
using drill in the
LO (1) speed range, speed will decrease
and unit will have more power and torque. When using drill in
the
HI (2) speed range, speed will increase and unit will have
less power and torque. Use
LO (1) speed for high power
and torque applications and
HI (2) speed for fast drilling or
driving applications.
