VARIABLE SPEED
The variable speed switch delivers higher speed 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)
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 forward drilling. The drilling direction is reversed when
the selector is to the right of the switch trigger.
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 4.
The drill has a two-speed gear train designed for drilling or
driving at LO (1) or HI (2) speeds. A switch is located on the
side 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, usually for drill bits larger than 3/8
in. Use HI (2) speed for fast drilling or driving applications,
usually for drill bits smaller than 3/8 in.
CAUTION:
To prevent gear damage, always allow the chuck to come
to a complete stop before changing gear speed.
