GENERAL POWER TOOL SAFETY WARNINGS

• WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fi re 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.

1. Work area safety
   • a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
   • b) Do not operate power tools in explosive atmos-pheres, such as in the presence of fl ammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
   • c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
2. Electrical safety
   • a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodifi ed plugs and matching outlets will reduce risk of electric shock.
   • b) Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of elec-tric shock if your body is earthed or grounded.
   • Do not expose power tools to rain or wet condi-tions. Water entering a power tool will increase the risk of electric shock.
   • Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
   • When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
   • f) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.
3. Personal safety
   • a ) Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the infl uence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
   • b) Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
   • c) Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool.
   • Carrying power tools with your fi nger on the switch or energising power tools that have the switch on invites accidents.
   • d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
   • e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
   • f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
   • g) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust related hazards.
   • h) Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.
4. Power tool use and care
   • a) Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
   • b) Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
   • c) Disconnect the plug from the power source and/or the battery pack from the power tool be-fore making any adjustments, changing acces-sories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
   • d) Store idle power tools out of the reach of chil-dren and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
   • e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
   • f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
   • g) Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
   • h) Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.
5. Service
   • a) 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.

ADDITIONAL SAFETY INSTRUCTIONS

• Do not use oversized sanding sheets, but follow the manufacturer’s specifi cations for the size of sanding sheets. Sanding sheets which project over the sanding pad may cause injuries as well as block and rip the sanding sheets or cause a kickback.
• It is not recommended to sand lead paint. Lead paint should be removed by a specialist only.
• Do not work on materials which release hazar-dous substances (e.g. asbestos). Take precauti-ons if hazardous, combustible or explosive dust is likely to occur. Wear protective dust mask. Use dust extraction system.
• If plaster board or plaster is sanded, this may cause static electricity to build up on the tool. To ensure your safety, the wall sander is earthed. Remove dust with an earthed dust extractor only.
• Do not work materials containing asbestos. Asbestos is considered carcinogenic.
• Do not use the machine for sanding magnesium workpieces.
• Wear safety goggles. Wear hearing protection. If necessary, use other protective means, such as safety gloves, safety shoes, etc.
• Hold the machine by the insulated gripping surfaces where the accessory may contact hid-den wiring or the mains cable. If the accessory contacts a ‚live‘ wire, the exposed metal parts of the machine can also become ‚live‘. Risk of electric shock.
• Be very careful when sanding painted surfaces.
• Before use, remove all nails and other metal objects from the workpiece.
• Make sure that the workpiece is properly sup-ported or fi xed.
• Only use sanding paper that is suitable for use with the machine.
• Only use sanding paper with the correct di-mensions. Make sure that the sanding paper is properly mounted.
• Inspect the sanding paper before each use. Do not use sanding paper that is worn because of prolonged use.
• Never put the machine down on a table or a workbench before it has been switched off.

Electrical safety

• Always check that the voltage of the power supply corresponds to the voltage on the rating plate label.
• Do not use the machine if the mains cable or the mains plug is damaged.
• Only use extension cables that are suitable for the power rating of the machine with a minimum thickness of 1.5 mm2. If you use an extension cable reel, always fully unroll the cable.
