OPERATION
ELECTRIC BRAKE
To stop the drill/driver, release the trigger
switch and allow the chuck to come to a
complete stop. The electric brake quickly
stops the chuck from rotating. This feature
engages automatically when you release the
trigger switch.
TWO-SPEED
GEARBOX (FIG. 4)
LO
HI
FIG. 4
The drill/driver has a two-speed gearbox for
drilling or driving at low or high speeds. A
slide switch is located on the top of the drill/
driver to select either low or high speed. The
required speed is adjusted depending on
the material and the working conditions.
Use low speed for high power and torque
applications and high speed for fast drilling
or driving applications.
When using drill/driver in the low speed
range, the speed will decrease and the drill/
driver will have more power and torque.
Use low speed for starting holes without
a center punch, drilling metals or plastic,
drilling ceramics, or in applications requiring
a higher torque.
High speed is better for drilling wood and
wood composites.
NOTICE: Avoid running the drill/driver at
high speed for extended periods of time.
Running at high speed under constant us-
age may cause the drill/driver to become
overheated.
CAUTION:
Never adjust the speed
while the tool is running. Failure to obey
this caution could result in serious damage
to the drill/driver.
NOTICE: Make sure that the two-speed
gearbox switch is fully adjusted at the front
or the back position.
KEYLESS CHUCK (FIG. 5)
FIG. 5
The drill/driver has a keyless chuck to
tighten or release bits in the chuck jaws. The
arrows on the chuck indicate the direction in
which to rotate the chuck in order to GRIP
(tighten) or OPEN (release) the chuck jaws
on the bit.
WARNING:
Do not hold the chuck
with one hand and use the power of the
drill/driver to tighten the chuck jaws on
the drill bit. The chuck could slip in your
hand, or your hand could slip and come
in contact with the rotating bit. This could
cause an accident resulting in serious
personal injury.
