kEYLESS CHUCk (Fig. 6)
The drill has a keyless chuck to
tighten or release drill bits in the
chuck jaws. The arrows on the chuck
indicate the direction in which to
rotate the chuck body in order to
LOCK (tighten) or UNLOCK (release)
the chuck jaws on 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 bit. This could cause an accident resulting in
serious personal injury.
TWO-SPEED GEAR BOX (Fig. 7)
The drill has a two-speed gear box
designed for drilling or driving at
LO or HI speeds. A slide switch is
located on the top of the drill to
select either LO or HI speed.
When using drill in the LO speed
range, the speed will decrease and
the drill will have more power and
torque. When using drill in the HI
speed range, the speed will increase
and the drill will have less power and
torque. Use LO speed for high power and torque applications and HI speed
for fast drilling or driving applications.
Use LO speed for starting holes without a center punch, drilling metals or
plastic, drilling ceramics, or in applications requiring a higher torque (see
below).
HI speed is better for drilling wood and wood composites and for using
abrasive and polishing accessories.
NOTE: Avoid running the drill at LO speed for extended periods of time.
Running at LO speed under constant usage may cause the drill to become
overheated. If this occurs, cool the drill by running it without a load at HI
speed.
CAUTION!
Never change gears while the tool is running. Failure to obey this
caution could result in serious damage to the drill.
