WARNING:
Do not hold chuck body with one hand and use 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.
DIRECTION OF ROTATION SELECTOR
(FORWARD/REVERSE/CENTER LOCK)
SWITCH TRIGGER
See Figure 5.
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 and
torque with increased trigger pressure and lower speed with
decreased trigger pressure.
NOTE: You might hear a whistling or ringing noise from the
switch during use. Do not be concerned; this is a normal
part of the switch function.
DIRECTION OF ROTATION SELECTOR
(FORWARD/REVERSE/CENTER LOCK)
See Figure 5.
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 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 changing 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.
INTERNAL SPINDLE LOCK
The internal spindle lock allows the user single-handed
control of chuck adjustments and bit changes. Squeezing
the chuck body stops the chuck jaws from turning. For bit
changes and chuck adjustments, squeeze the chuck body
and turn.
KEYLESS CHUCK
See Figure 6.
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.
