The Hammer Drill can be switched from IMPACT (impact plus rotation) to ROTATION (rotation only) by rotating the change lever (Fig. 1). When boring concrete, stone, tile or similar hard materials, rotating the change lever to IMPACT side. The drill head impacts against the material while continuing to rotate.

When boring metal, wood or plastic, rotating the change lever to ROTATION side. The drill rotates as an ordinary electric drill.

CAUTION

Do not use the Hammer Drill in the IMPACT function if the material can be bored by rotation only. Such action will not only reduce drill efficiency, but may also damage the drill tip.

In this case, swith ON and operate the machine for few seconds. The spindle shaft will then be pushed forward, and the change lever can be moved smoothly.
