Only diamond cut-off wheels must be used. Bonded cut-off wheels must not be used for cutting off. The diamond cut-off wheel used must be matched to the angle grinder. The operating instructions of the angle grinder of the diamond cut-off wheel and the dust extractor must be observed. The safety guard is suitable for professional cutting off (without the use of water) of concrete, granite, marble, ceramic tiles or masonry with the use of suitable diamond cut-off wheels. It is not designed for processing metal, plastic, lumber, fiberglass or others materials that do not contain cement. The user bears sole responsibility for any damage caused by improper use. Generally accepted accident prevention regula- tions and the enclosed safety information must be observed. For your own protection and for the protection of your electrical tool, pay attention to all parts of the text that are marked with this symbol! WARNING – Reading the operating instruc- tions will reduce the risk of injury. Before using this power tool, completely read and understand the enclosed safety information and the instructions. Keep all enclosed documentation for future reference, and pass on your power tool only together with these documents. 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, 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.

2.1 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 atmospheres, such as in the presence of flam- mable 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.

2.2 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 out- lets 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.

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 medi- cation. 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 finger 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

2. General Safety InstructionsENGLISHen

these are connected and properly used. Use of dust collection can reduce dust-related hazards.

2.4 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 before making any adjustments, changing accessories, 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 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. Check for misalign- ment 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. 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.

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. These operating instructions are intended for persons with basic technical knowledge and experi- ence of the operation of machines such as the one described herein. If you have no experience what- soever with such power tools, we strongly recom- mend to seek the advice of an experienced person. Prior to use of the power tool, users must be provided with information, instructions and training. Use a suitable dust extractor that complies with all country-specific specifications.

3.1 Safety instructions for abrasive cut-off

machines The safety guard must be securely attached to the power tool and positioned for maximum safety, so the least amount of wheel is exposed towards the operator. Ensure that neither you or bystanders are positioned within the plane of the rotating diamond cut-off wheel. The guard helps to protect operator from broken wheel frag- ments and accidental contact with the diamond cut- off wheel. Only use diamond cut-off wheels for your power tool. Just because the accessory can be attached to your power tool, it does not assure safe operation. When not in use, place power tool on a stable surface where it will not move inadvertantly, roll or cause a tripping or falling hazard. Serious personal injury may result. Never lay the power tool down until the acces- sory has come to a complete stop. The spinning accessory may grab the surface and pull the power tool out of your control. Do not run the power tool while carrying at your side. Accidental contact with the spinning acces- sory could snag your clothing, pulling the accessory into your body. Do not operate the power tool near flammable materials. Sparks could ignite these materials. Position the cord clear of the spinning acces- sory. If you loose control, the cord may be cut or snagged and your arm may be pulled into the spin- ning wheel. Do not use accessories that require liquid cool- ants. Using water or other liquid coolants may result in electrocution or shock.

3.2 Kickback and Related Warnings

Kickback is the sudden response to a diamond cut- off wheel that is jammed or blocked while rotating. Jamming causes the rotating accessory to stop abruptly, This, in turn, causes the uncontrolled power tool to be forced in the direction opposite to the accessory’s rotation at the point of blocking. If a diamond cut-off wheel jams or blocks in the workpiece, the edge of the wheel entering into the workpiece can snag, thus causing either kickback or the wheel to break off. Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below. a) Maintain a firm grip on the power tool and position your body and arm to allow you to resist kickback forces. Hold the power tool as specified (see chapter 6.1) to ensure maximum control over kickback forces or torque reac- tions during run-up. The operator can control torque reactions or kickback forces, if proper precautions are taken. b) Never place your hand near the rotating accessory. Accessory may kickback over your hand. c) Do not positon your body in line with the rotating accessory. Accessory may kickback over your hand.

d) Use special care when working around corners, sharp edges etc. Avoid bouncing and snagging the accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and cause loss of control or kickback. e) Do not attach a saw chain, woodcarving blade, segmented diamond wheel with a peripheral gap gerater than 10 mm or toothed blade. Such blades create frequent kickback and loss of control. f) Do not jam the cut-off wheel or apply exces- sive pressure. Do not attempt to make an excessive depth of cut. Overstressing the diamond cut-off wheel increases the loading and susceptibility to twisting or jamming of the wheel in the cut and the possibility of kickback or wheel breakage. g) If the diamond cut-off wheel gets jammed or you interrupt operation for any reason, switch off the power tool and hold the power tool still until the wheel comes to a complete stop. Never attempt to remove the diamond cut-off wheel from the cut while the wheel is in motion, otherwise kickback may occur. Investigate and take corrective action to eliminate the cause of wheel jamming. h) Do not restart the power tool while in the workpiece. Let the diamond cut-off wheel reach full speed and carefully reenter the cut. Other- wise the diamond cut-off wheel may bind, jump up or kick back.

i) Support panels or any oversized workpiece

to minimize the risk of wheel pinching and kick- back. Large workpieces tend to sag under their own weight. The workpiece must be supported on both sides of the diamond cut-off wheel near the line of cut and near the edge of the workpiece on both sides of the wheel. j) Use extra caution when making a "pocket cut" into existing walls or other blind areas. The protruding wheel may cut gas or water pipes, elec- trical wiring or objects that can cause kickback.

3.3 Additional Safety Instructions

Always wear protective goggles. Wear personal protective equip- ment. Use a full face shield, safety goggles dust mask, ear protectors, protective gloves, workshop apron, non-slip safety shoes. Dust from material such as paint containing lead, some wood species, minerals and metal may be harmful. Contact with or inhalation of the dust may cause allergic reactions and/or respiratory diseases to the operator or bystanders. Certain kinds of dust are classified as carcinogenic, such as oak and beech dust, especially in conjunction with additives for wood conditioning (chromate, wood preservative). Material containing asbestos must only be treated by specialists. - Use a dust extraction device. - Use a suitable dust extractor that complies with all country-specific specifications. - The work place must be well ventilated. - Always wear a respirator (NIOSH/OSHA- approved). Follow national requirements for the materials you want to work with. Materials that generate dusts or vapors that may be harmful to health (e.g. asbestos) must not be processed. Wear ear protectors when working for long periods of time. High noise levels over a prolonged period of time may affect your hearing. Keep the handles dry, clean and free of oil and grease. Greasy, oily handles can slip, leading to a loss of control. Wear working gloves. Safe guidance of the power tool is not possible with sweaty hands. Working gloves help avoid accidental sliding and thus prevent accidents. Never work on ladders or similar objects. Ensure you stand in a safe position and keep your balance at all times. The workpiece must lay flat and be secured against slipping, e.g. using clamps. Large workpieces must be supported adequately. Do not use any accessories that are not specifically designed and recommended by the tool manufac- turer. Just because the accessory can be attached to your power tool, it does not assure safe opera- tion. Accessories must be stored and handled with care in accordance with the manufacturer's instructions. The outside diameter and the thickness of your accessory must comply with the dimensions of your power tool. Incorrectly sized accessories cannot be adequately guarded or controlled. The operating instructions of the angle grinder used must be observed. The rated speed of the accessory must be at least equal to the maximum speed marked on the power tool. Accessories running faster than their rated speed can break and fly off. Furthermore, only use diamond cut-off wheels certified for a rotational speed of 12000 rpm. Use a diamond cut-off wheel that is suitable and certified for the material being processed. If a segmented diamond cut-off wheel is used, it must have a negative cutting angle and the slots between the segmented material must not be larger than 10 mm. Make sure the direction of rotation is correct. The direction of rotation is marked by arrows on the diamond cut-off wheel and safety guard. The arrows must point in the same direction. Ensure that the diamond cut-off wheel is fitted correctly and securely on the power tool. Damaged, eccentric or vibrating tools must not be used.ENGLISHen

The diamond cut-off wheel must not be overheated. Overheating can result in material failure and lead to serious injury. Do not use damaged accessories. Before use, always check the accessories for chips and cracks. If a power tool or accessory is dropped, inspect for damage or install an undamaged accessory. After inspecting and installing an accessory, position yourself and bystanders away from the plane of the rotating accessory and run the power tool at maximum no-load speed for one minute. Damaged accessories will normally break apart during this test time. Stop immediately if significant vibrations occur or if other defects are noted. If such a situation occurs, check the machine to determine the cause. Never place your hand near the rotating accesso- ries. Never touch the safety guard housing or the protective flap while the accessory is rotating. Keep all body parts well away from the accessory while the machine is running. Pay close attention to all safety guards. One moment's carelessness can result in serious injuries. The lateral protective flap (2) must only be folded away when working on inside corners. During all other work, the protective flap (2) must cover the diamond cut-off wheel. When cutting off, always work against the run of the wheel (see page 2, illustration D). Otherwise there is the danger of the machine kicking back uncon- trolledly from the cut. Guide the machine evenly at a speed suitable for the material being processed. Do not tilt, apply excessive force or sway from side to side. Do not execute abrupt or uncontrolled move- ments which could result in accidents. Do not switch on the machine if tool parts or guard devices are missing or defective. Never use an incomplete machine, or one on which an unauthor- ized modification has been made. Ensure that the point where you wish to work is free of power cables, gas lines or water pipes (e.g. by using a metal detector). Make sure that no other objects can come into contact with the accessory. Cutting accessory contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock. Keep children and other persons well away from the power tool when in use. If you are distracted, you could lose control over the power tool. Keep bystanders a safe distance away from the work area. Anyone entering the work area must wear personal protective equipment. Fragments of work- pieces or a broken accessory may be ejected and cause injury even beyond the immediate area of operation. Pull the plug out of the plug socket before any adjustments, conversions or servicing are performed. Before use, always check that the safety guard is fitted correctly and securely on the angle grinder. Caution: Parts of the diamond cut-off wheel can break and fly off. A damaged or cracked safety guard must be replaced. Never operate a machine with a defective safety guard. Do not switch on the machine if tool parts or guard devices are missing or defective. The safety guard is designed for use with Metabo angle grinders WQ 1000 with 4“, 4-1/2“ or 5" acces- sory diameters. The diamond cut-off wheel used must be matched to the angle grinder. The oper- ating instructions of the angle grinder of the diamond cut-off wheel and the dust extractor must be observed.
