OPERATION

Fig. 5

Fig. 4

WARNING:

If any parts are missing, do not operate tool until the
missing parts are replaced. Failure to do so could result
in possible serious personal injury.

SWITCH

See Figure 4.

Your drill starts and stops by depressing and releasing the
switch trigger. Release the switch trigger to turn drill OFF.

VARIABLE SPEED

See Figure 4.

Your drill has a variable speed feature in the switch. The
switch delivers higher speed and torque with increased
trigger pressure. Speed is controlled by the amount of
switch trigger depression.

SWITCH LOCK

See Figure 4.

The switch trigger can be locked in the OFF position. This
feature helps reduce the possibility of accidental starting
when not in use. To lock the switch trigger, place the direction
of rotation selector in the center position.

REVERSIBLE

See Figure 4.

This tool is reversible. The direction of rotation is controlled
by a direction of rotation 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 for drilling. The drilling direction is reversed
when the selector is to the right of the switch. When the
selector is in center position, the switch trigger is locked.

CAUTION:

To prevent gear damage, always allow chuck to come to
a complete stop before changing the direction of rotation.

To stop, release switch trigger and allow the chuck to come
to a complete stop.

WARNING:

Battery tools are always in operating condition. Therefore,
switch should always be locked when not in use or when
carrying at your side.

TWO SPEED GEAR TRAIN

See Figure 5.

Your drill has a two-speed gear train designed for drilling or
driving at LO (1) or HI (2) speeds. A slide switch is located
on top of your drill to select either LO (1) or HI (2) speed.
When using drill in the LO (1) speed range, speed will
decrease and unit will have more power and torque. When
using drill in the HI (2) speed range, speed will increase and
unit will have less power and torque.  Use LO (1) speed for
high power and torque applications and HI (2) speed for
fast drilling or driving applications.
