• This equipment is not insulated against contact with an electric cable. It is vital to avoid all contact with electric cables. The equipment is not suitable for use in explosive atmospheres.
• • The equipment is not suitable for use in explosive atmospheres. Sparks may be created when you work with this equipment. It is important therefore that you never work with this equipment near combustible materials, liquids, or gases.

Dangers due to dust and vapors

• Depending on the material you wish to process, dust and gases may arise that are a health hazard for the user (for example causing cancer, birth defects, asthma and / or dermatitis).
• Make sure that escaping air whirls up as little dust as possible.
• Wear a suitable protective dust mask which complies with the particular case of application and the generally applicable safety rules.

Dangers due to noise

• Noise can cause permanent damage to your hearing. Unprotected exposure to high levels of noise can result in loss of hearing and other problems such as tinnitus (ringing, buzzing, whistling or droning noises in your ears). Wear ear-muffs.
• To keep noise and vibration levels as low as possible, follow the maintenance and operating instructions in the manual. For example, vibration-damping material used as an intermediate layer when working on sheet metal can also reduce noise.

Dangers due to vibrations

• Vibrations can injure the nerves and cause blood circulation disorders in your hands and arms.
• Wear warm clothing when you work in cold surroun – dings. Keep your hands warm and dry.
• Stop using the equipment if you experience numbness, tingling, pain, or whitening of the skin on your fingers or hands, and consult a doctor.
• Do not hold the plug-in tool with your free hand as this will lead to a higher vibration load.
• Hold the equipment with a light but secure grip, noting the reaction forces which arise in the process.
• The risk of disorders caused by vibrations is always greater with a tight grip.

Additional safety information for pneumatic machines

• Compressed air can cause serious injuries.
• Disconnect the compressed air coupling and depressurize the equipment before your service, repair, or transport the equipment and before you change the chisel.
• Never direct compressed air at yourself or at any other persons.
• Whipping hoses may cause serious injuries. You must always make sure therefore that the hoses and their fasteners are undamaged and have not become disconnected.
• When you release the quick-lock coupling, hold the hose securely in your hand and never use defective connectors. This will help to prevent injuries caused by a whipping compressed air hose.
• Do not let cold air flow over your hands.
• Do not use any quick-lock couplings at the air inlet. Use hose connections with a hardened steel thread (or a material with comparable resistance to vibrations).
• If universal rotary couplings (claw couplings) are used, lock pins must be installed, and a retention system for compressed air hoses used in order to protect against possible faulty connections („hose to tool“ or „hose to hose“).
• Do not exceed the maximum permissible operating pressure.
• Do not carry compressed air tools by their hoses.
• Keep this safety information in a safe place.
