OPERATION FOR DRILL/DRIVER
WARNING:
Do not hold the chuck with
one hand and use the power of the tool to
tighten the chuck jaws on the 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.
TWO-SPEED GEARBOX
See Figure 7, page ii
The tool has a two-speed gearbox for
drilling or driving at LO or HI speeds. A slide
switch is located on the top of the tool to
select either LO or HI speed.
1. For LO speed, slide the switch to the side
with the mark "1".
2. For HI speed, slide the switch to the side
with the mark "2".
Use LO speed for high power and high
torque applications; use HI speed for fast
drilling, driving or drilling applications. When
using the tool in the LO speed range, the
speed will decrease and the tool will have
more power and torque. Use LO speed for
starting holes without a center punch, drilling
metals or plastic, drilling ceramics, drilling
holes in brick, concrete or in applications
requiring a higher torque. HI speed is better
for drilling wood and wood composites and
for using abrasive and polishing accessories.
NOTICE:
Avoid running the tool at HI speed
for extended periods of time. Running at HI
speed under constant usage may cause the
tool to become overheated. If this occurs,
cool the tool by running it without a load at
LO speed.
NOTICE:
Never change gears while the tool
is running. Failure to obey this caution could
result in serious damage to the tool.

MODE SELECTOR

See Figure 7, page ii
The tool is equipped with a selector for
driving different types of screws/nuts/holes
into different materials. To use the torque
setting, rotate the mode selector to the driver
mode (1-19 positions), or drill mode (
The proper setting depends on the type of
material and the application.
ADJUSTABLE-TORQUE CLUTCH
See Figure 8, page ii
The higher the torque setting, the more force
the drill produces to turn an object in either
LO or HI rotation speed. When using the drill
for different driving applications, increase or
decrease the torque in order to help prevent
damage to screw heads, threads, workpieces,
etc.
Adjust the torque by rotating the torque-
adjustment ring. The proper setting depends
on the job and the type of bit, fastener, and
material you will be using. In general, use
greater torque for larger screws. If the torque
is too high, the screws may be damaged
or broken. For delicate operations, such as
removing a partially stripped screw, use a low
torque setting. For operations such as drilling
into hardwood, use a higher torque setting.
NOTICE:
When adjusting the torque clutch
make sure that the speed switch is either
completely in the LO or HI position.
NOTICE:
Do not change the torque setting
when the tool is running.
INSTALLING BITS
See Figure 9, page ii
1. Lock the trigger switch by placing the
direction-of-rotation selector in the OFF
(center-lock) position.
2. Open or close the chuck jaws to a point
where the opening is slightly larger than
the bit you intend to use.
3. Raise the front of the drill slightly to keep
the bit from falling out of the chuck jaws.
4. Insert a bit.
5. Rotate the chuck in the direction of the
arrow marked GRIP to close the chuck
jaws.
NOTICE:
Do not use a wrench to tighten or
loosen the chuck jaws.
6. Tighten the chuck jaws securely on the bit.
NOTE:
When the bit is fixed in chuck jaws,
you will hear a 'click'.
