PRECAUTIONS ON USING ROTARY HAMMER

1.Wear earplugs to protect your ears during operation.

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.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.
