manufacturer or authorized service providers.
2.2 Hammer safety warnings
Safety instructions for all operations
▶ Wear ear protectors. Exposure to noise can cause hearing loss.
▶ Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.
▶ Hold the power tool by insulated gripping surfaces, when performing an operation where the
cutting accessory may contact hidden wiring. Cutting accessory contacting a "live" wire may make
exposed metal parts of the power tool "live" and could give the operator an electric shock.
Safety instructions when using long drill bits with rotary hammers
▶ Always start drilling at low speed and with the bit tip in contact with the workpiece. At higher
speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in
personal injury.
▶ Apply pressure only in direct line with the bit and do not apply excessive pressure. Bits can bend
causing breakage or loss of control, resulting in personal injury.

Additional safety instructions

Personal safety
▶ Use the product and accessories only when they are in perfect working order.
▶ Never tamper with or modify the product or accessories in any way.
▶ Wear protective gloves when changing accessory tools, because the accessory tool and the tool holder
get hot during use.
▶ In accordance with the applications for which it is designed, the product produces a high torque. Always
hold the tool with both hands on the grips provided. The user must be prepared for sudden sticking and
stalling of the accessory tool.
▶ Check that the side handle is fitted correctly and tightened securely. Always grip the side handle at its
outermost end.
▶ Working on the material may cause it to splinter. Flying fragments present a risk of injury to the eyes and
body. Wear eye protection, a hard hat and ear protection while the product is in use. In addition, wear
light respiratory protection if you are not using a dust extractor.
▶ Apply appropriate safety measures at the opposite side of the workpiece in work that involves breaking
through. Parts breaking away could fall out and / or fall down causing injury to other persons.
▶ When chiseling into ceilings, walls and floors, always make sure that you have a safe and firm stance. A
sudden break-through can affect your balance.
▶ Do not touch rotating parts – risk of injury!
▶ Keep the air vents clear at all times. Risk of burn injuries due to blocked air vents!
▶ Switch the product on only after you have brought it to the working position.
▶ Do not work in an environment heavily contaminated with dust.
▶ 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.
▶ 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 look directly into the light source (LEDs) of the power tool and do not aim the beam at other
persons' faces. Risk of dazzling or eye damage.
▶ Prevent ingress of moisture. A short circuit caused by moisture can result in fire or burn injuries.
▶ Risk of injury by falling tools and/or accessories. Before starting work, check that the battery and installed
accessories are secure.
