A) WARNING: Never modify the power tool or any part of it. Damage or personal injury could result. Refer to Figure A at the beginning of this manual for a complete list of components. Intended Use Your heavy‑duty demolition hammer is designed for professional demolition, chipping and chasing applications in concrete, brick, stone and other masonry materials. DO NOT use under wet conditions or in presence of flammable liquids or gases. Your heavy‑duty demolition hammer is a professional power tool. DO NOT let children come into contact with the tool. Supervision is required when inexperienced operators use this tool. Soft Start Feature The soft start feature allows the impact rate to build up more slowly, thus preventing the chisel or point from "bouncing" around on the masonry when starting up. Active Vibration Control The active vibration control neutralizes rebound vibration from the hammer mechanism. Lowering hand and arm vibration, it allows more comfortable use for longer periods of time and extends the life of the unit. ASSEMBLY AND ADJUSTMENTS WARNING: To reduce the risk of serious personal injury, turn unit off and disconnect it from power source before making any adjustments or removing/installing attachments or accessories. An accidental start‑up can cause injury.

Failure to do so may result in the bail/loop style auxiliary handle slipping during tool operation and subsequent loss of control. Hold tool with both hands to maximize control. The bail/loop style auxiliary handle 5 clamps to the front of the gear case and may be rotated 360˚ to permit right- or left-hand use. Mounting the Bail/Loop Style Auxiliary Handle (Fig. B) 1. Widen the ring opening 8 of the bail/loop style auxiliary handle 5 by rotating the screw for handle mounting 6 counter clockwise. 2. Slide the assembly onto the nose of the tool through the ring opening 8 and onto the chisel position index collar 3 , past the chisel holder and sleeve. 3. Rotate the bail/loop style auxiliary handle to the desired position. 4. Lock the bail/loop style auxiliary handle in place by securely tightening the screw for handle mounting 6 rotating it clockwise so that the assembly will not rotate. 4
