▶ Wear eye protection, a hard hat and ear protection while the product is in use.
▶ Before beginning work, check the working area for concealed electric cables or gas and water pipes.
External metal parts of the product could give you an electric shock or cause an explosion if you
accidentally damage an electric cable or a gas or water pipe.
▶ You and everyone in the work zone must wear personal protective equipment while the product is in
use. Depending on the application, wear a face shield, eye protection or safety glasses that can protect
against flying fragments of the workpiece. If appropriate, wear a dust mask, hearing protection, protective
gloves and a workshop apron that can protect against flying fragments of the workpiece.
▶ Wear protective gloves when changing the accessory tool. Touching the accessory tool can result in
cuts and burns.
▶ Wear eye protection. Flying fragments present a risk of injury to the body and eyes.
▶ Before starting grinding work, carefully remove all protruding parts such as nails, screws, etc.
▶ Tighten the accessory tool and flange securely. If the accessory tool and flange are not tightened
securely, the accessory tool may work loose from the arbor due to the braking effect of the motor after
switching off.
▶ The product is not suitable for removing epoxy resin.
▶ Ensure that the workplace is well ventilated. Exposure to dust at a poorly ventilated workplace may result
in damage to the health.
▶ Dust produced by grinding, sanding, cutting and drilling can contain dangerous chemicals. Some
examples are: lead or lead-based paints; brick, concrete and other masonry products, natural stone
and other products containing silicates; certain types of wood, such as oak, beech and chemically
treated wood; asbestos or materials that contain asbestos. Determine the exposure of the operator and
bystanders by means of the hazard classification of the materials to be worked. Implement the necessary
measures to restrict exposure to a safe level, for example by the use of a dust collection system or by
the wearing of suitable respiratory protection. The general measures for reducing exposure include:
▶ working in an area that is well ventilated,
▶ avoidance of prolonged contact with dust,
▶ directing dust away from the face and body,
▶ wearing protective clothing and washing exposed areas of the skin with water and soap.
▶ Do not use the product if sealing lips on the dust hood are worn; never use the product without a dust
extractor. Replace the sealing lips when they are worn out.
▶ Take frequent breaks and do physical exercises to improve the blood circulation in your fingers. High
vibration during long periods of work can lead to disorders of the blood vessels and nervous system in
the fingers, hands and wrists.
▶ Do not attach a belt hook to this product.
▶ Switch the product on only after you have brought it to the working position.

Failure to comply can lead to skin irritation, severe corrosive injury, chemical burns, fire and/or explosion.
▶ Use only batteries that are in perfect working order.
▶ Treat batteries with care in order to avoid damage and prevent leakage of fluids that are extremely
harmful to health!
▶ Do not under any circumstances modify or tamper with batteries!
▶ Do not disassemble, crush or incinerate batteries and do not subject them to temperatures over 80 °C
(176 °F).
▶ Never use or charge a battery that has suffered an impact or been damaged in any other way. Check
your batteries regularly for signs of damage.
▶ Never use recycled or repaired batteries.
▶ Never use the battery or a battery-operated power tool as a striking tool.
▶ Never expose batteries to the direct rays of the sun, elevated temperature, sparking, or open flame. This
can lead to explosions.
