DIRECTION OF ROTATION SELECTOR
{FORWARD/REVERSE/CENTER LOCK)
See Figure 4.
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.

helps reduce the possibility of accidental starting when not
In use.
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.
