▶
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.
▶
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.
▶
Risk of injury by falling tools and/or accessories. Before starting work, check that the battery and
installed accessories are secure.
▶
Do not use blunted bits.
▶
Use large, heavy accessory tools only with the power tool set to first gear. There is otherwise a risk
of causing damage to the power tool when switching it off or, under unfavorable circumstances,
the chuck may work loose.
▶
Use auxiliary handles supplied with the product. Loss of control can cause personal injury. Make
sure that the auxiliary handle is firmly seated and securely installed.
▶
Switch the product on only after you have brought it to the working position.
▶
Secure the workpiece. Use clamps or a vice to hold the workpiece in position. The workpiece is
thus held more securely than by hand and both hands remain free to operate the power tool.
▶
Always hold the product with both hands on the grips provided. Keep the grips clean and dry.
▶
Keep the air vents clear at all times. Risk of burn injuries due to blocked air vents!
▶
Do not touch rotating parts – risk of injury!
▶
Wear eye protection, a hard hat and ear protection and suitable respiratory protection while the
product is in use.
▶
Wear eye protection. Flying fragments can injure the body and eyes.
▶
Do not look directly into the light source (LED) of the product and do not aim the beam at other
persons' faces. Risk of dazzling or eye damage.
▶
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.
▶
Wait until the product has come to a complete stop before you lay it down.
▶
Wear protective gloves when changing the accessory tool. Touching the accessory tool can result
in cuts and burns.
Careful handling and use of batteries
▶
Comply with the following safety instructions for the safe handling and use of Li-ion batteries.
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!
