OPERATION

VARIABLE SPEED

See Figure 5.

Your hammer drill has a variable speed control selector
designed to allow operator control and adjustment of speed
and torque limits. Speed and torque can be increased or
decreased by rotating the variable speed control selector in
the direction of the arrows shown in figure 5.

NOTE:  Hold your hammer drill in normal operating position
and turn the  variable speed control selector clockwise to
increase the speed and torque of your hammer drill. Turn
counterclockwise to decrease the speed and torque of your
hammer drill.

If you desire to lock the switch on at a given speed, depress
the switch trigger, push in and hold the lock-on button, and
release the switch trigger. Next, adjust the variable speed
control selector until the desired speed is reached.

NOTE: IF THE VARIABLE SPEED CONTROL SELECTOR
IS FULLY TURNED IN THE COUNTERCLOCKWISE
DIRECTION (ZERO SETTING) YOUR DRILL MAY NOT
RUN.

IF YOU DESIRE NOT TO USE THE VARIABLE SPEED
CONTROL SELECTOR, TURN IT IN THE FULL
CLOCKWISE DIRECTION.  THIS WILL ALLOW THE
SPEED OF YOUR DRILL TO BE FULLY CONTROLLED
BY THE AMOUNT OF SWITCH TRIGGER DEPRESSION.

Avoid running your hammer drill at low speeds for extended
periods of time. Running at low speeds under constant usage
may cause your drill to become overheated. If this occurs,
cool your drill by running it without a load and at full speed.

The following guidelines may be used in determining correct
speed for various applications:

LOW speed is ideal when minimum speed and power is
required. For example: starting holes without center punching,
driving screws, mixing paint, and drilling in ceramics.

MEDIUM speed is suitable for drilling hard metals, plastics,
and laminates.

HIGH speed produces best results when maximum power is
required. For example: drilling in wood; soft metals such as
aluminum, brass, and copper; and when using driving
accessories.

WARNING:

Your hammer drill should never be connected to power
supply when you are assembling parts, making adjust-
ments, installing or removing drill bits, or when not in use.
Disconnecting your drill will prevent accidental starting
that could cause serious injury.

INSTALLING AUXILIARY HANDLE

See Figure 6.

AN AUXILIARY HANDLE IS PACKED WITH YOUR DRILL
