Inserting and removing bits

This drill has a keyless chuck, which means that a chuck key is not needed to secure a bit in the drill.

1.Open the chuck by holding the rear section of the chuck firm and rotating the front section in a anti-clockwise direction, sufficiently enough to allow the drill bit required to fully enter the jaws of the chuck.

2.Ensure the drill bit is fully inserted, so that the chuck

jaws grip the straight section of the bit.

3.Holding the rear section of the chuck firmly, rotate the front section of the chuck clock-wise until the jaws tighten on the drill bit. The front section of the chuck needs to be tightened firmly to ensure the drill bit is held securely.

4.To remove the drill bit, hold the rear section of the chuck firmly and rotate sharply the front section of the chuck in a anti-clockwise direction, sufficiently enough to allow the drill bit to be removed.

Adjustable side handle

1.Turn the side handle clamp knob (6) anti-clockwise

to loosen the collar fully and slip it over the chuck (1) onto the drill.

2.Adjust the position of the side handle (5) to suit the application and tighten the side handle clamp knob (6) to secure it in place.
