5 Safety instructions

General power tool safety warnings

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.

1) Work area safety

a) Keep your work area clean and well-lit. Cluttered or dark areas invite accidents. b) 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. 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. Unmodified 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 electric shock if your body is earthed or grounded. c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. d) 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. e) 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 influence 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 a 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 a power source and/or battery pack, picking up, or carrying the tool. Carrying power tools with your finger on the switch or energizing 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 jewelry. Keep your hair and clothing away from moving parts. Loose clothes, jewelry, 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 remove the battery pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools. Such precautionary measures reduce the risk of starting the power tool accidentally. d) Store idle power tools out of the reach of children 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 and accessories. 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.

5.1 Safety instructions for cut-off machines

a) The protective cover belonging to the electric tool must be securely attached and adjusted so that the highest degree of safety is achieved, i.e. the smallest possible part of the grinding wheel is revealed to the operator. Keep yourself and people nearby out of the plane of the rotating grinding disc. The protective cover is intended to protect the operator from fragments and accidental contact with the grinding wheel.

b) Only use diamond-coated cutting discs for your power tool. Just because you can attach the accessories to your electrical appliance does not guarantee safe use.

c) The maximum speed of the accessory tool used must be at least as high as the maximum speed specified for the power tool. Accessories which rotate faster than the maximum permissible rate can break and throw pieces into the air.

d) Grinding bodies may only be used for the recommended applications. For example: Never grind on the side surfaces of a cutting wheel. Cutting wheels are designed to remove material with the edge of the disc. Lateral forces on this grinding body can break it.

e) Always use undamaged clamping flanges of the correct size and shape for the grinding disc selected by you. Suitable flanges support the grinding disc and reduce the danger of the grinding disc breaking.

f) The external diameter and thickness of the accessory tool used must comply with the dimensions of the power tool. Incorrectly dimensioned accessory tools cannot be sufficiently shielded or controlled.

g) Grinding discs and flanges must fit exactly on your electrical tool's grinding spindle. Insertion tools that do not fit exactly on your electrical tool's grinding spindle rotate unevenly, vibrate very strongly and can cause a loss of control.

h) Do not use damaged grinding discs. Check the grinding discs for chipping and cracks before each use. If the electric tool or grinding disc falls, check whether it is damaged, or use an undamaged grinding disc. Once you have checked and inserted the grinding disc, keep yourself and anyone in the vicinity out of the plane of the rotating grinding disc and allow the appliance to run at maximum speed for one minute. Damaged grinding discs usually break during this test period.

i) Wear personal protective equipment. Depending on the application, use a face shield, safety goggles, or safety glasses. Where appropriate, wear a dust mask, hearing protection, protective gloves, or a special apron that will keep small grinding and material particles away from you. The eye protection must be capable of stopping flying debris generated by various operations. Dust or breathing masks must filter the dust generated during use. Prolonged exposure to high intensity noise may cause hearing loss.

j) Ensure that other people remain at a safe distance from 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.

k) Hold the power tool by insulated gripping surfaces only when performing an operation where the cutting accessory 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.

l) Keep the power cord away from any rotating accessories. If you lose control of the device, the mains cable can be severed or caught, and your hand or arm could be pulled into the rotating insert tool.

m) Never put the power tool down until the accessory tool being used has come to a complete standstill. The rotating accessory tool can come into contact with the surface and cause you to lose control of the power tool.

n) Do not run the power tool while carrying it at your side. Accidental contact of your clothing with the rotating attachment part could lead to injury.

o) 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.

p) Never use the power tool in the vicinity of inflammable materials. Sparks can ignite such materials.

q) Do not use any accessory tools that require liquid coolant. The use of water or other liquid coolants may lead to an electric shock.

5.2 Kick-back and corresponding safety instructions

Kick-back is the sudden reaction resulting from a caught or jammed rotating insert tool, such as a grinding disc, grinding wheel, etc. Catching or jamming results in the rotating insert tool stopping abruptly. As a result, an uncontrolled electric tool is accelerated against the direction of rotation of the tool attachment at the blocking point.

For example, if a grinding disc catches or jams in the workpiece, the edge of the grinding disc that plunges into the workpiece can get caught, causing the grinding disc to break away or kick back. The grinding disc may either jump toward or away from the operator, depending on the direction of the wheel's movement at the point of pinching. Abrasive wheels may also break under these conditions.

Kick-back is the result of incorrect or deficient use of the power tool. It can be prevented by suitable precautionary measures, as described in the following.

a) Hold the power tool firmly in both hands and position your body and arms so they can absorb the force of a kickback. Always use the additional handle, if available, so that you have the maximum possible control over the kickback force or reaction forces at full speed. By taking adequate precautions, the operator can stay in control of the kickback and reaction forces.

b) Never hold your hand close to a rotating accessory tool. The accessory tool could jump out of your hand if there is a kickback.

c) 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.

d) Take special care when working near corners, sharp edges, etc. Avoid allowing the accessory tool to bounce back from the workpiece or jam. The rotating tool attachment tends to jam at corners, sharp edges or when it bounces back. This causes a loss of control or kick-back.

e) Never use a chain or toothed saw blade, or any segmented diamond grinding wheel with slots of a width of more than 10 mm. Such accessories often cause a kickback or loss of control over the power tool.

f) Avoid blocking the cutting wheel or applying too much pressure. Do not make excessively deep cuts. Overloading the cutting wheel increases its stress and susceptibility to tilting or blocking and therefore the possibility of kick-back or breaking of the grinding wheel.

g) If the cutting wheel jams or you interrupt your work, switch the device off and hold it still in the material until the disc has come to a standstill. Never try to pull the cutting wheel out of the cut while it is still running, otherwise kick-back may occur. Determine and remedy the cause of the jamming.

h) Do not switch the electric tool on again while it is in the workpiece. Allow the cutting wheel to reach its full speed first before carefully continuing the cut. Otherwise the disc can get stuck, jump out of the workpiece or cause kick-back.

i) Support plates or large workpieces to reduce the risk of kick-back caused by a jammed cutting wheel. Large workpieces tend to sag under their own weight. The workpiece must be supported on both sides of the disc, that is both close to the cutting wheel and at the edge.

j) Apply particular caution with "plunge cuts" in existing walls or other areas that are not visible. The plunging cutting wheel can cause kick-back when cutting into gas or water pipes, electrical lines or other objects.
