Variable Speed - Craftsman 315.119100 Operator's Manual

SWITCH TRIGGER
See Figure 3.
To turn the drill ON, depress the switch trigger. To turn it
OFF, release the switch trigger.

VARIABLE SPEED

The variable speed switch trigger delivers higher speed
with increased trigger pressure and lower speed with de-
creased trigger pressure.
NOTE: You might hear a whistling or ringing noise from
the switch during use. Do not be concerned; this is a nor-
mal part of the switch function.
DIRECTION OF ROTATION SELECTOR
(FORWARD/REVERSE/CENTER LOCK)
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.
Setting the switch trigger in the OFF (center lock) position
helps reduce the possibility of accidental starting when
not in use.
CAUTION:
To prevent gear damage, always allow
the chuck to come to a complete stop before chang-
ing 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.
KEYLESS CHUCK
See Figure 4.
The drill has a keyless chuck to tighten or release drill
bits in the chuck jaws. The arrows on the chuck indicate
which direction to rotate the chuck body in order to LOCK
(tighten) or UNLOCK (release) the drill bit.
WARNING:
Do not hold the chuck 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 drill bit. This could cause an
accident resulting in serious personal injury.
