SWITCH TRIGGER
See Figure 3, page 11.
To turn the drill ON, depress the switch trigger. To turn it
OFF, release the switch trigger.
VARIABLE SPEED
The variable speed dial delivers higher speed by turning the
variable speed dial clockwise. For slower speeds, turn the
dial counterclockwise.
The variable speed switch delivers higher speed with
increased trigger pressure and lower speed with decreased

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.

OPERATION

LOCK-ON BUTTON
See Figure 3, page 11.
This drill is equipped with a lock-on feature, which is con-
venient for continuous drilling for extended periods of time.
To lock-on:
 Depress the switch trigger.
 Push in and hold the lock-on button, located on the side
of the handle.
 Release the switch trigger.
 Release the lock-on button and the drill will continue
running.
 To release the lock, depress and release the switch
trigger.
If the lock-on feature is engaged during use and the drill
becomes disconnected from the power supply, disengage
the lock-on feature immediately.
WARNING:
Before connecting the drill to a power supply source,
always check to be sure it is not in lock-on position (de-
press and release the switch trigger). Failure to ensure
that it is not locked-on could result in accidental starting
of the drill resulting in possible serious injury. Do not lock
the switch trigger in applications where the drill may need
to be suddenly stopped.
DIRECTION OF ROTATION SELECTOR
(FORWARD/REVERSE)
See Figure 4, page 12.
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 trig-
ger for forward drilling. The drilling direction is reversed
when the selector is to the right of the switch trigger.
NOTICE:
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.
