 How to use Percussion Tools

Hammers, Rotary Hammer and Hammer Drills: This family of tools is primarily associated with masonry applications as varied as chipping, drilling, anchor setting and breaking of pavement. They range from pistol grip types to large demolition hammers. Normal operating modes include hammering, hammering with rotary motion and rotation or drilling only. Many models incorporate a varied combination of the above modes.

Capacity is normally rated in maximum diameter displayed on the nameplate. Do not attempt to use a bit larger than that which is specified unless otherwise recommended in the owner/operators manual.

Before operating, compare the date on the nameplate with the voltage source and be sure that the voltage and frequency are compatible.

Always wear safety goggles or safety glasses with side shields complying with current national standard, and a full face shield when needed. Use a dust mask in dusty work conditions. Wear hearing protection during extended periods of operation.

Do not wear gloves, loose clothing, jewelry or any dangling objects that may catch in rotating parts or accessories. Tie back long hair.

For maximum control and to resist torque caused by unexpected stalls, use the auxiliary handles provided with the tool.

Do not tamper with clutches on those models that provide them. Have the clutch settings checked at the manufacturer's service facility at the intervals recommended in the owner/operators manual.

Check for subsurface hazards such as electrical conductors or water lines before drilling or breaking blindly into a surface. If wires are present, they must be disconnected at the power source by a qualified person, or be certain they are avoided to prevent the possibility of lethal shock or fire. Water pipes must be drained and capped. Always hold the tool by the insulated grasping surfaces.

Do not force the tool. Percussion tools are designed to hit with a predetermined force. Added pressure by the operator only causes operator fatigue, excessive bit wear and reduced control.

Keep the operators work area clear of debris.

Always provide firm footing.

Percussion tools with rotating features require compliance with all of the operating considerations referred to under drills in this brochure. Remember to unplug the tool before changing bits or servicing.
