2.1 General safety instructions

WARNING! Read all safety warnings, instructions, illustrations and specifications
provided with this power tool. Failure to follow all instructions listed below 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 Machine-specific safety notices for cordless drills
- Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory or fastener may contact hidden wiring. Cutting accessory or fasteners contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.
- 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.

- 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!
- Hold the power tool firmly in your hand. Adjust the torque correctly for screwing. Be prepared for a high reaction torque, which may cause the power tool to turn and possibly lead to injury.
- 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 Emission levels
Levels determined in accordance with EN 60745 are typically:
Sound pressure level L PA=73 dB(A)
Sound power level L WA=84 dB(A)
Uncertainty K = 3 dB

Wear ear protection.
Vibration emission value a_h (vector sum for three directions) and uncertainty K measured in accordance with EN 60745:
Drilling in metal a = 5,6m / s^2
K = 1,5 ~m / s^2
Fastening a h < 2,5m / s^2
K = 1,5m / s^2
The specified emission 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 note of idling and downtimes of machine!
3 Intended use
Cordless drill suitable for
drilling in metal, wood, plastic and similar materials,
- inserting and tightening screws

The user is liable for improper or non-intended use; this also includes continuous industrial operation.
