VARIABLE SPEED SWITCH
See Figure 2,
To turn the drill ON, depress the variable speed switch. To
turn it OFF, release the switch.
VARIABLE SPEED
The variable speed switch delivers higher speed and
torque with increased pressure and lower speed with
decreased 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.
UNLOCK
(RELEASE)
KEYLESS CHUCK
See Figure 2.
The drill-driver has a keyless chuck that makes it simple 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 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 drill bit. This could cause an
accident resulting in serious personal injury.
FORWARD/REVERSE
See Figure 2.
The direction of bit rotation is reversible and is controlled
by a selector located above the variable speed switch.
With the drill held in normal operating position, the direc-
tion of rotation selector should be positioned to the left
of the switch for drilling. The drilling direction is reversed
when the selector is to the right of the variable speed
switch.
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 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.
