ROTARY HAMMER
EN
•
When working always hold the tool firmly. It is allowed to work with a tool only holding it with both hands. It is
recommended to use the side handle during each operation. One-hand tool management may lead to loss of
control. Also when chiseling, parts from hard materials such as reinforcing bars, may be dangerous. Tighten the
side handle securely before starting work.
•
Continuous work with this electric tool during a long period of time is not allowed. Vibration produced during
hammering may cause harm to your hands or feet. Use gloves for better anti-vibration protection and limit the
effects of vibration, taking frequent breaks in work.
•
Do not attempt to repair the working tooling by yourself. The repairing must be carried out by a qualified
technician. Chisels, drill bits, etc. which are restored incorrectly may cause injury or tool failure.
•
Wear gloves when working with electric tool or when changing the tooling. Working tooling may become very
hot during the work and cause burns to unprotected hands.
•
Never lay the tool until the full stop of the tooling. Rotating chisel or drill bit may cause injury.
•
Never hit with a hammer on jammed tooling trying to free it. Particles of the workpiece or metal shavings may
bounce off and cause injury.
•
Hold electrical cable away from the rotating working tool. Do not wrap the cable around any part of your body.
Electrical cable, wound on a rotating working tooling, may cause loss of control of the tool and serious injury.
ATTENTION:
It is recommended to use a safety shutdown device with actuation current not more
than 30 mA.
Residual risks
In spite of the compliance with relevant security means instructions and use of safety devices, some residual risks
cannot be completely eliminated. They are:
•
injuries caused by touching hot or rotating instrument parts;
•
impairment of hearing;
•
risk of pinching fingers when changing working tool;
•
damage to health due to vibration appearing at work;
•
damage to health due to inhalation of dust when working with concrete and/or bricks.

Electrical Rotary Hammer represents an impact rotary machine consisting of electric drive and actuator. An electric
drive of the electrical rotary hammer is an alternating current collector motor housed in a plastic case. Actuating
mechanism driving the working tool consists of an impact mechanism combination of the vacuum compression
type (creating a directional impact without returning) and a rotation drive.
