Trigger Switch; Variable Speed; Keyless Chuck; Two-Speed Gearbox - Craftsman nextec 320.10003 Operator's Manual

TRIGGER SWITCH (Fig. 5)
To turn the Drill ON, depress
the trigger switch. To turn it
OFF, release the trigger switch.
VARIABLE SPEED (Fig.5)
The variable-speed trigger
switch delivers higher speed
with increased trigger pressure
and lower speed with de-
creased trigger pressure.

selector
DIRECTION-OF=ROTATION
SELECTOR (FORWARD/
REVERSE/CENTER
LOCK) (Fig. 5)
The direction of bit rotation is reversible and is controlled by a selector located
above the trigger switch.
With the Drill held in normal operating position:
1. Position the direction-of-rotation selector to the left of the tool for drilling.
2. Position the direction-of-rotation selector to the right of the tool for reverse.
3. Setting the switch in the OFF (center lock) position helps reduce the possi-
bility 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.
NOTE: The Drill will not run unless the direction-of-rotation selector is engaged
fully to the left or right.
ELECTRIC BRAKE
To stop the Drill, 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.
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 GRIP (tighten) or
OPEN (release) the chuck jaws
on the Drill bit.
_J_ 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 GEARBOX (Fig. 7)
The Drill has a two-speed
gearbox 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 the Drill in
the HI speed range, the speed will increase and the Drill will have more driving
power and twisting force (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 plas-
tic, 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.
