Handling instruction
2 Safety warnings
2.1 General power tool safety warnings

WARNING! Read all safety warnings, instructions, illustrations and specifica-
tions 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.
Follow the operating manual for the charger and the battery pack.
2.2 Machine-specific safety notices
- 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.
- Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the workpiece by hand or against your body leaves it unstable and may lead to loss of control.
- Use appropriate detection devices to look for any hidden supply lines or consult your local utility company. If the insertion tool makes contact with live cables, it can result in fire and electric shock. Damage to a gas pipe can lead to an explosion. Penetration of a water pipe can result in damage to property.
- Harmful/toxic dust may be produced during your work (e.g. paint containing lead, certain types of wood and metal). Only qualified persons are permitted to handle materials containing asbestos. Aontact with or inhalation of this dust may pose a risk for the operating personnel or persons in the vicinity. Comply with the safety regulations that apply in your country.
Wear a P2 respiratory mask to protect health.





Wear suitable personal protective equipment: Ear protection, protective goggles, dust mask for work that generates dust, protective gloves for working with rough materials and for changing tools.
- Grip the electric power tool securely so that your body never comes into contact with the operating tool, especially when working with saw blades or cutting tools directed towards the grip area, for example. Contact with sharp blades or edges can result in injuries.
- After machining materials that contain gypsum: Clean the vents of the power tool and on/off switch using dry, oil-free compressed air. Otherwise, gypsum dust deposits may build up inside the power tool's housing and on the on/off switch and hard-en when exposed to humidity. This may impair the switching mechanism
- Wait until the power tool has come to a complete halt before placing it down. The insertion tool can get caught and lead to a loss of control of the power tool.
- Do not use power supply units or third-party battery packs to operate cordless power tools. Do not use third-party chargers to charge the battery packs. The use of accessories not expressly authorised by the manufacturer can result in electric shocks and/or serious accidents.
- Do not use the power tool in the rain or in damp surroundings. Moisture in the power tool may cause a short circuit and fire.
2.3 Metal processing

When processing metal, the following measures must be taken for safety reasons:
- Connect the machine to a suitable dust extractor.
- Regularly blow out the motor housing of the machine to remove dust deposits.

Wear protective goggles.
2.4 Emission levels
The levels determined in accordance with EN 62841 are typically:
Sound pressure level L _PA = 83 dB(A)
Sound power level L _WA = 93 dB(A)
Peak sound pressure level L_pC_peak = 97 dB(C)
Uncertainty K = 3 dB


CAUTION
Noise generated when working Risk of damage to hearing
▶ Use ear protection.
Vibration emission level a_h (vector sum for three directions) and uncertainty K measured in accordance with EN 62841:
- are used to compare machines.
- They are also used for making preliminary estimates regarding vibration and noise load during operation.
- They represent the primary applications of the power tool.

CAUTION
The emission values may deviate from the specified values. This is dependent on how the tool is used and the type of workpiece being machined.
▶ The actual load during the entire operating cycle must be evaluated.
▶ Depending on the actual load, suitable protective measures must be defined in order to protect the operator.
