Fig. 5
Your drill has a variable speed switch designed to
allow operator control of speed and torque limits. The
speed and torque of your drill can be increased by
depressing the switch trigger.
Note: Depress switch trigger all the way for maximum
speed and torque of your drill. Depress switch trigger
only part of the way for less speed and torque.
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.

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