VARIABLE SPEED
See Figure 5.
Your hammer drill has a variable speed control switch
that delivers higher speed with increased trigger pres-
sure. Speed is 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 over-
heated. 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 inwood, 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 assem-
bling parts, making adjustments, installing or
removing drill bits, or when not in use. Discon-
necting your drill will prevent accidental starting
that could cause serious injury.
