OPERATION

DIRECTION OF ROTATION SELECTOR

(FORWARD/REVERSE) See Figure 3.

The direction of bit rotation is reversible and is controlled by a selector located above the switch trigger. With the drill held in normal operating position, the direction of rotation selector should be positioned to the left of the switch trigger for forward drilling. The drilling direction is reversed when the selector is to the right of the switch trigger.

CAUTION:

To prevent gear damage, always allow the chuck to come to a complete stop before changing the direction of rotation.

To stop the drill, release the switch trigger and allow the chuck to come to a complete stop.

NOTE: The drill will not run unless the direction of rotation selector is pushed fully to the left or right.

Avoid running the drill at low speeds for extended periods of time. Running at low speeds under constant usage may cause the drill to become overheated. If this occurs, cool the drill by running it without a load and at full speed.

TO INSTALL BITS

See Figures 4 - 5.

Unplug the drill.

Insert the chuck key and twist counterclockwise.

Open or close the chuck jaws to a point where the opening is slightly larger than the bit size you intend to use. Also, raise the front of the drill slightly to keep the bit from falling out of the chuck jaws.

WARNING:

Make sure to insert the drill bit straight into the chuck jaws. Do not insert the drill bit into the chuck jaws at an angle then tighten, as shown in figure 5. This could cause the drill bit to be thrown from the drill, resulting in possible serious personal injury or damage to the chuck.

Insert the drill bit.

Tighten the chuck jaws securely on the drill bit, using the chuck key provided.

Remove the chuck key.

TO REMOVE BITS

See Figure 4.

Unplug the drill.
