SAFETY INSTRUCTIONS

DANGER!

• Lack of knowledge of the safety instructions can pose a danger of extremely severe or even fatal injury.
• Lack of knowledge of the safety instructions and operating instructions can lead to extremely serious and even fatal injury.
• Observe all safety instructions] and instructions for use in these operating instructions as well the operating instructions which are referred to before you start using the appliance.
• Keep all supplied documents in a safe place for future reference.

General safety instructions for power tools

WARNING

• Read all safety instructions, instructions, illustrations and technical data that are provided with this power tool.
• Failure to comply with the following instructions can lead to an electric shock, fire and/or series injuries.
• Keep all safety instructions and other instructions for future reference.

The term “power tool” used in the safety instructions refers to mains-operated power tools (with mains line) and to batteryoperated power tools (without mains line).

Electrical safety

• The connection plug of the power tool must fit into the socket. The plug is not allowed to be changed in any way. Do not use any plug adapters together with earthed power tools. Unmodified plugs and matching sockets reduce the risk of electric shock.
• Avoid physical contact with earthed surfaces such as pipes, heaters, cookers, and refrigerators. There is an increased risk of electric shock if your body is earthed.
• Keep electrical tools out of the rain and away from moisture. Water getting intoan electrical tool increases the risk of an electric shock.
• Do not use the cable for incorrect purposes such as carrying the electrical tool, hanging it up, or pulling the plug out of the socket. Keep the cable away from heat, oil, sharp edges or moving parts.
• Damaged or tangled cables increase the risk of an electric shock.
• If you are working outside with a power tool, only use extension leads that are also suitable for outdoor use. Using an extension lead that is suitable for outdoor use reduces the risk of electric shock.
• If the operation of the power] tool in a humid environment cannot be avoided, use a fault current circuit breaker. Using a fault current circuit breaker decreases the risk of electric shock.

Personal safety

• Be alert, pay attention to what you are doing and take a cautious approach to working with a power tool.
• Do not use a power tool if you are tired or under the influence of drugs, alcohol or medicines. A moment’s inattentiveness when using the power tool can result in serious injury.
• Wear personal protective equipment, and always use safety goggles. The injury risk can be reduced by wearing personal protective equipment such as a dust mask, non-slip shoes, a protectivehelmet or ear defenders, depending on the type and application of the power tool.
• Avoid starting to operate the appliance inadvertently.
• Ensure the switch is in the off-position before connecting to a power source and/or battery pack, picking up or carrying the power tool. Accidents can be caused by leaving your finger on the switch when you carry the power tool or when you connect it to the power supply.
• Remove the adjusting tools or spanner before you switch on the power tool. A tool or spanner that is in a rotating part of the power tool can cause injury.
• Avoid an abnormal bodily posture. Make sure you can stand safely and keep your balance at all times. This will enable you to control the power tool better if something unexpected happens.
• Wear suitable clothing. Do not wear baggy clothing or jewelry. Keep your hair and clothing away from moving parts. Loose clothing, jewellery or long hair can be snagged on moving parts.
• If dust extraction and catchment devices can be mounted, then these must be connected correctly used. Using a dust extraction system can reduce the risk caused by dust.
• Do not give yourself a false sense of safety; do not ignore the safety rules for power tools even if you are familiar with the power tool after using it many times. One careless action can lead to serious injuries within seconds.

Use and handling of the electrical tool

• Do not overload the power tool. Use the appropriate power tool for the job you are doing. Using the appropriate power tool will enable you to work more effectively and safely in the specified performance range.
• Do not use a power tool if it has a defective switch. A power tool that can no longer be switched on or off is dangerous and must be repaired.
• Disconnect the plug from the socket and/or remove the battery before you make adjustments to the appliance, replace parts or put the power tool away. This precautionary measure will prevent the power tool from starting inadvertently.
• Keep unused power tools out of the reach of children. Do not allow people to use the power tool if they are not familiar with it or have not read these instructions. Power tools are dangerous if they are used by inexperienced people.
• Look after power tools and the insertion tool with care. Check whether moving parts function perfectly and do not stick, and whether there are any broken parts or parts that are damaged in such a way that the function of the power tool is impaired.
• Have damaged parts repaired before using the power tool. Many accidents are caused by failure to maintain power tools properly.
• Keep cutting tools sharp and clean. Carefully maintained cutting tools with sharper cutting edges are less likely to stick and are easier to control.
• Use power tools, accessories, insertion tools, etc. according to these instructions. When doing so, take account of the working conditions and the activity to be undertaken. Using power tools for applications other than the intended purpose can result in dangerous situations.
• Keep the grips and grip surfaces dry, clean and free from oil and grease. Slippery grips and grip surfaces prevent safe operation and control of the power tool in unforeseen situations.

Safety in the workplace

• Keep your working area clean, and make sure it is well illuminated. Untidiness or dimly lit working areas can lead to accidents.
• Do not work with the power tool in a potentially explosive atmosphere with the presence of flammable liquids, gases or dust. Power tools give rise to sparks that can ignite dust or vapors.
• Keep children and other people away from the power tool when using it. If you are distracted, you may lose control of the power tool.
