Battery tool use and care
▶ Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type
of battery pack may create a risk of fire when used with another battery pack.
▶ Use power tools only with specifically designated battery packs. Use of any other battery packs may
create a risk of injury and fire.
▶ When battery pack is not in use, keep it away from other metal objects, like paper clips, coins,
keys, nails, screws or other small metal objects, that can make a connection from one terminal to
another. Shorting the battery terminals together may cause burns or a fire.
▶ Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact
accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid
ejected from the battery may cause irritation or burns.
▶ Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may
exhibit unpredictable behaviour resulting in fire, explosion or risk of injury.
▶ Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature
above 130° C (265 °F) may cause explosion.
▶ Follow all charging instructions and do not charge the battery pack or tool outside the temperature
range specified in the instructions. Charging improperly or at temperatures outside the specified range
may damage the battery and increase the risk of fire.
Service
▶ Have your power tool serviced by a qualified repair person using only identical replacement parts.
This will ensure that the safety of the power tool is maintained.
▶ Never service damaged battery packs. Service of battery packs should only be performed by the
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.
2.3 Additional safety instructions for rotary hammer drill
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.
▶ Use auxiliary handles supplied with the product. Loss of control can cause personal injury.
▶ 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.
▶ Always hold the tool with both hands on the grips provided. Keep the grips clean and dry.
▶ Hold the product by the insulated gripping surfaces when performing work in which the accessory tool
might come into contact with concealed wiring. If the accessory tool comes into contact with a live wire,
metal parts of the power tool can also become live, resulting in an electric shock.
▶ 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 protective gloves when changing the accessory tool. Touching the accessory tool can result in
cuts and burns.
▶ Wear eye protection. Flying fragments can injure the body and eyes.
