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.

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 drill at low speeds for extended
periods of time. Running at low speeds under con-
stant 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.
