LOCK-ON BUTTON

See Figure 3.

Your drill is equipped with a lock-on feature which is convenient when continuous drilling for extended periods of time is required. To lock-on, depress the switch trigger, push in and hold the lock-on button located on the side of the handle, then release switch trigger. Release lock-on button and your drill will continue running.

To release the lock, depress the switch trigger and release.

If you have the lock-onfeature engaged during use and your drill becomes disconnected from power supply, disengage the lock-on feature immediately.

VARIABLE SPEED

See Figure 3.

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.

TWO SPEED GEAR TRAIN

See Figure 4.

Your drill has a two-speed gear train designed for drilling or driving at LO (1) or HI (2) speeds. A slide switch is located on top of your drill to select either LO (1) or HI (2) speed. When using drill in the LO (1) speed range, speed will decrease and unit will have more power and torque. When using drill in the HI (2) speed range, speed will increase and unit will have less power and torque. Use LO (1) speed for high power and torque applications and HI (2) speed for fast drilling or driving applications.
