2 Safety instructions
2.1 General safety instructions

WARNING! Read all safety warnings and all instructions. Failure to follow the warnings
and instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
2.2 Safety instructions for specific drills
- Hold 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.
- Use auxiliary handles supplied with the tool. Loss of control can cause personal injury.
- Wear ear protection. Exposure to noise can result in loss of hearing.
- Use suitable detectors to determine if utility lines are hidden in the work area or call the local utility company for assistance. Contact with electric lines can lead to fire and electric shock. Damaging a gas line can lead to explosion. Penetrating a water line causes property damage or may cause an electric shock.
- Harmful/toxic dust may be produced during your work (e.g. paint containing lead, certain types of wood and metal). Inhaling or coming into contact with this dust may represent a hazard for operating personnel or persons in the vicinity. Comply with the safety regulations that apply in your country.

Wear a P2 dust mask to protect your health.

- Wear suitable protection: such as ear protection, safety goggles, a dust mask for work which generates dust, and protective gloves when working with raw materials and when changing tools.

CAUTION! Power tool can block and cause sudden kickback! Switch off immediately!
- If a tool becomes stuck in the material, it can be removed simply by reversing the rotational direction of the machine.
- Do not use the power tool in the rain or in damp surroundings. Moisture in the power tool may cause a short circuit and burning.
- Do not lock the on/off switch permanently!
2.3 Battery pack and charger safety instructions
- This charger can be operated by persons with re-
GB BHC 18
duced physical, sensory or mental capabilities or a lack of practical experience and knowledge, provided they are supervised or have been instructed to use the machine safely and understand the dangers of machine operation.
Children are not allowed use or play with the machine.
- Do not open the battery pack or the charger!
- Prevent metal parts (e.g. from entering the charger!
- Risk of explosion! Do not use battery packs or chargers from other manufacturers!
- Protect the battery pack from excessive heat > 50 °C or constant heat sources such as sunlight or naked flames!
- Never use water to extinguish burning li-ion battery packs! Use sand or a fire blanket.
- Check the plug and the cable regularly and should either become damaged, in order to avoid a hazard, have them replaced by an authorised after-sales service workshop.
- Protect the machine from moisture.
- Protect the cable from heat, oil and sharp edges.
- Always pull the mains plug out of the socket when the charger is not in use.
- Only for AS/NZS: The tool shall always be supplied via residual current device with a rated residual current of 30 mA or less.
2.4 Emission levels
Levels determined in accordance with EN 60745 are typically:
Hammer drilling in concrete
Sound pressure level L _PA = 88 dB(A)
Noise level L _WA = 99 dB(A)
Uncertainty K = 3 dB

CAUTION
When working with noise
Damage to hearing
▶ Always use ear protection.
Vibration emission value a_h (vector sum for three directions) and uncertainty K measured in accordance with EN 60745:
| a_h | K | |
| Hammer drilling in concrete | 13,8 m/s2 | 3,4 m/s2 |
The specified emissions values (vibration, noise)
- are used to compare machines.
- They are also used for making preliminary estimates regarding vibration and noise loads during operation.
- They represent the primary applications of the power tool.
Increase possible for other applications, with other insertion tools or if not maintained adequately. Take metal chips or fluids note of riding and downtimes of machine!
3 Intended use
Cordless rotary hammer suitable
