PRECAUTIONS ON USING ROTARY HAMMER

1.Wear ear protections

Exposure to noise can cause hearing loss.

2.Do not touch the bit during or immediately after operation. The bit becomes very hot during operation and could cause serious burns.

3.Before starting to break, chip or drill into a wall, floor or ceiling, thoroughly confirm that such items as electric cables or conduits are not buried inside.

4.Use auxiliary handles supplied with the tool. Loss of control can cause personal injury.

5.Always hold the body handle and side handle of the power tool firmly. Otherwise the counterforce produced may result in inaccurate and even dangerous operation.

6.Wear a dust mask

Do not inhale the harmful dusts generated in drilling or chiseling operation. The dust can endanger the health of yourself and bystanders.
