OPERATION
VARIABLE SPEED
See Figures 5 & 8.
Your drill has a variable speed dial designed to allow
operator control of speed and torque limits. The speed
and torque of your drill can be increased by turning the
dial on top of the drill.
Avoid running your 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 drill should never be connected to power
supply when you are assembling parts, making
adjustments, installing or removing drill bits, clean-
ing, or when not in use. Disconnecting your drill will
prevent accidental starting that could cause seri-
ous personal injury.
TWO-SPEED GEAR SHIFT KNOB
See Figure 6.
The hammer drill has a two-speed gear shift knob which
provides a high speed of approximately 3,000 RPM and a
low speed of approximately 1,000 RPM (stated speeds are
with the trigger switch in "Full-On" position).
WARNING:
Failure to unplug your drill could result in acciden-
tal starting causing serious injury.
For high speed operation, rotate two-speed gear shift knob
clockwise aligning with indicating mark on knob. For low
speed operation, rotate knob counterclockwise with
indicating mark on knob. It may be necessary to rotate the
chuck by hand while rotating knob.
CAUTION:
Never change gears while the tool is running.
Failure to obey this caution could result in serious
damage to the drill.
TO INCREASE SPEED,
PULL SWITCH TRIGGER
WARNING:
The hammer drill should never be connected to a
power supply when you are assembling parts,
making adjustments, cleaning, performing
maintenance, or when the tool is not in use.
Disconnecting the tool will prevent accidental start-
ing that could cause serious injury.
