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.
