A General Power Tool Lil Safety Warnings

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.

1. Work area safety
   • Keep work area clean and well lit. Cluttered or dark areas invite accidents.
   • Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
   • Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical safety

• 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. Unmodified plugs and matching outle15 will reduce risk of electric shock.
• Avoid body contact with earthed or grounded surfaces, such as pipes, radiaton, cookers and refrigerators. There is an increased risk of elec­tric shock if your body is earthed or grounded.
• Do not expose power tools to rain or wet conditions. 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 isk of electric shock.
• When operating a power tool outdoors, use an extension cord suitable for outdoor u1e. Use of a cord suitable for outdoor use reduces the risk of electric shock.
• 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.

Personal safety

• Stay alert, watch what you are doing and use common 1en1e when operating a power tool. Do not u1e a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
• 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.
• 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 finger on the switch or energising power tools that have the switch on invites accidents.
• 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.
• Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
• 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.
• 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 dusl-related hazards.

Power tool use and care

• 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 ii was designed.
• 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.
• Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing acceuories, or storing power tools. Such preventive safely measures reduce the risk of starting the power tool accidentally.
• Store idle power tools out of the reach of children and do not allow penons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
• 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 acci- dents are caused by poorly maintained power tools.
• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
• Use the power tool, accessories and tool bits etc. in accordance with these instructions, tak- ing 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.

Service

• 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.

Safety instructions for abrasive cutting appliances

• The blade guard, which is a part of the power tool, must be attached securely and set in a way that ensures maximum safety, i.e. the smallest possible amount of the grinding tool is exposed to the operator. Ensure that you and anyone else in the vicinity remain outside of the range of the rotating grinding disc. The blade guard is designed to protect the operator from fragments and accidental contact with the grinding tool.
• Use only diamond-coated cutting discs for your power tool. Just because you can attach the accessories to your power tool, does not ensure they are safe to use.
• The maximum speed of the accessory tool used must be at least as high as the maximum speed specified for the power tool. Accessories that rotate faster than the maximum permissible rate can break and throw pieces into the air.
• Grinding tools should only be used for the recommended applications. For example: Never grind with the side surface of a cutting disc. Cutting discs are designed to remove the material with the edge of the disc. Any lateral application of force on these grinding tools can lead to breakage.
• Always use an undamaged clamping flange of the correct size and shape for the selected grinding disc. Suitable flanges support the grinding disc and reduce the risk of disc breakage.
• Do not use worn grinding discs from larger power tools. Grinding discs for larger power tools are not designed for the higher rotational speeds of smaller power tools and can break.
• The external diameter and thickness of the accessory tool used must comply with the dimensions of your power tool. Incorrectly dimensioned accessory tools cannot be sufficiently shielded or controlled.
• Grinding discs and flanges must fit precisely onto the grinding spindle of your power tool. Accessory tools which do not fit precisely on the grinding spindle of the power tool will rotate unevenly, vibrate severely and can lead to a loss of control.
• Do not use damaged grinding discs. Check the grinding discs before each use for chips and cracks. If the power tool or grinding disc is dropped, check to see if it either are dam- aged, or use an undamaged grinding disc. After checking and inserting the grinding disc, ensure that you and any other people in the vicinity remain outside of the range of the rotating grinding disc, and allow the tool to rotate at maximum speed for one minute. Damaged grinding discs usually break during th is test period.
• Wear personal protective equipment. Depending on the application, ensure that you use full face protection, eye protection or goggles. If required, use a dust mask, ear protectors, protective gloves or special apron to protect you from grindings and material particles. Eyes should be protected from flying debris that may be generated during certain applications. Dust or filter masks must filter any dust created by the application. If you are exposed to loud noise for any length of time, you can suffer a hearing loss.
• Ensure that other people remain at a safe dis­tance to your workspace. Anyone who enters the workspace must wear personal protective equipment. Fragments of the workpiece or bro­ken accessory tools can fly off and cause injury
  • even outside the immediate working area.
• Hold power tool by the insulated gripping surfaces, when performing an operation where the accessory tool may contact hidden wiring or its own cord. Contact with a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
• Keep the power cord away from any rotating accessories. If you lose control of the appliance, the cord may get cut or caught and your hand or arm could get caught in the rotating accessory tool.
• Never put the power tool down until the ac­cessory tool has come to a complete standstill. The rotating accessory tool could come into contact with the surface and cause you to lose control of the power tool.
• Do not leave the power tool running whilst carrying it. Accidental contact between your clothing and the rotating accessory tool could cause your clothing to get caught and the ac­cessory tool to penetrate a part of your body.
• Clean the ventilation slits of your power tool regularly. The engine fan draws dust into the housing and a strong accumulation of metal dust can cause electrical hazards.
• Do not use the power tool in the vicinity of flammable materials. Sparks can ignite such materials.
• Do not use any accessory tools which require liquid coolant. The use of water or other liquid coolants may lead to electric shock.

Further safety instructions for abrasive cutting applications

• Kickback and corresponding safety instructions Kickback – causes and corresponding safety instructions
• Kickback is a sudden reaction caused when a rotating grinding disc catches or jams. Catching or jamming causes the rotating accessory tool to stop abruptly. If this happens, an uncontrolled power tool turns rapidly against the direction of rotation of the accessory tool caught in the blockage.
• If, for example, a grinding disc catches or jams, the edge of the grinding disc that is projecting into the workpiece can get caught and break off the grinding disc or cause a kickback. The grinding disc can then fly in the direction of the operator or away from him, depending on the direction of rotation of the disc at the blockage. This can also break grinding discs.

A kickback is caused by incorrect use ar misuse of the power tool. This can be avoided by taking proper precautions as given below.

• Hold the power tool firmly in both hands and position your arms so they can absorb the force of a kickback. Always use the additional handle, if available, so you have the maximum control over the kickback force or reaction torques at full speed. By taking adequate pre­cautions, the operator can stay in control of the kickback and reaction torques.
• Never hold your hand close to a rotating accessory tool. The accessory tool could hit your hand in the case of a kickback.
• Avoid the area in front of and behind the rotat­ing cutting disc. The kickback will force the power tool in the opposite direction to the direction of rotation of the grinding disc at the blockage.
• Take special care when working around corners, sharp edges, etc. Avoid allowing the accessory tool to bounce back from the workpiece or jam. The rotating accessory tool is more likely to jam in corners or sharp edges or if it bounces. This can cause a loss of control or kickback.
• Do not use a toothed or chain saw blade or segmented diamond-coated disc with more than 1 0 mm wide slits. Such accessory tools cause a kickback or loss of control over the power tool.
• Avoid cutting disc jams or excessive contact pressure. Do not make any excessively deep cuts. Overloading the cutting disc increases the stress and likelihood of tilting or jamming and thus the possibility of kickback or breakage of the grinding tool.
• If the cutting disc jams or you stop working, switch the tool off and hold it steady until the disc has completely stopped turning. Never attempt to pull a rotating cutting disc out of a cut. This could lead to a kickback. Identify and remove the cause of the jam.
• Do not switch the power tool back on as long as it is in the workpiece. Allow the cutting disc to reach its full speed before you carefully continue the cut. Otherwise, the disc may jam, jump out of the workpiece or cause kickback.
• Support panels or large workpieces to reduce the risk of the cutting disc jamming and causing a kickback. Large workpieces can bend under their own weight. The workpiece must be sup­ported on both sides, namely in the vicinity of the cut and also at the edge.
• Be particularly careful when making “pocket cuts” into existing walls or other obscured areas. The inserted cutting disc may cut into gas or water pipes, electrical wiring or other objects that can cause kickback.
