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 safety warnings and information for future reference! The term "power tool" in the safety warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

2.1 Work area safety

(62841) 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 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.

2.2 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 power tool. 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 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 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

1. Specified Conditions of Use

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.

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 remove the battery pack, if detachable, 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 and accessories with care. 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 safe handling and control of the tool in unexpected situations.

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. For your own protection and for the protection of your power tool, pay attention to all parts of the text that are marked with this symbol! a) Do not use a damaged accessory. Before each use, inspect the accessory such as abrasive wheel for chips and cracks, wire brushes for loose or cracked wires. 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. b) 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 apart. c) Be aware that wire bristles are thrown by the wire brush even during ordinary operation. Do not overstress the wires by applying excessive load to the wire brush. The wire bristles can easily penetrate light clothing and/or skin. d) Never grind on the sides of a grinding wheel. Grinding on the side can cause the wheel to break and fly apart. The sanding disc must match the machine. Observe the maximum sanding disc diameter and thickness. The hole diameter must match the back flange without play. Do not use adapters or reducers. Do not drill sanding discs. Do not trim discs. The sanding discs must be fitted perfectly and turn freely. Prior to using the grinding wheels, ensure that they are free from defects. A sound inspection has to be carried out to detect cracks. Damaged, eccentric or vibrating or deeply furrowed sanding discs must not be used. When clamping the sanding discs, only the flanges included in the delivery must be used. The intermediate layers between flange and sanding tool must be made of elastic materials, e.g. soft cardboard etc. Protect sanding discs against shocks, bumps and grease. Grinding wheels must be stored and handled with care in accordance with the manufacturer's instructions. Do not touch the rotating sanding disc! Always use the guard (8), the workpiece support (10), the transparent guard/eye protection (11) and the spark deflector (13) as required for the tools; Only work when the safety cover (1) is fitted. Swivel the eye preservers (11) downwards before sanding. Use the perimeter (not the sides) of the grinding wheels for grinding. Do not reduce the speed of the sanding disc by pressing on the sides.

The workpiece to be processed must be large enough, or small enough, to be held safely with both hands. Only work when the grinding wheels are fitted to minimise the risk of coming into contact with the rotating spindle. High temperatures can result after long-term operation. LED light (12): do not observe the LED radiation directly with optical instruments. CAUTION Do not stare at operating lamp. WARNING Always wear eye goggles, hearing protection and protective gloves. Use other available personal protective equipment, e.g. suitable protective work clothing. Ensure that sparks produced during work do not constitute a risk to the user or others and are not able to ignite flammable substances. Areas at risk must be protected with flame-resistant covers. Always keep a fire extinguisher on hand when working in areas prone to fire risk. The workpiece can become hot during sanding. Do not allow water within the vicinity of electric machine parts or close to people in the working area. If a grinding material blockage occurs, switch off the grinder immediately, allow the motor to stop and unplug the grinder. Identify the cause and remove the blockage. Clean, check and perform maintenance work on the machine and guard devices regularly. Regularly clean the inside of the grinding wheels housing. The grinding wheels must be able to rotate freely within the housing. Unplug when the grinder is not in use, before making any adjustments or carrying out modifications, repairs or maintenance. Regularly check the power cable on the grinder and have it repaired by an approved expert if damaged. Regularly check extension cables and replace if damaged. Check the grinder for possible damage: Before using the grinder, protective devices or slightly damaged components must be carefully checked to ensure they are operating perfectly and as intended. Check that moving parts are in perfect working order and do not jam and check whether parts are damaged. All parts must be correctly installed and fulfil all conditions necessary to ensure the perfect operation of the machine. Damaged protective devices and parts must be repaired or replaced according to specifications by an authorised specialist workshop. Additional Warnings: California Prop 65 08_2018 Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead-based paints,

• Crystalline silica from bricks and cement and other masonry products, and

• Arsenic and chromium from chemicallytreated lumber. Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

During transport (9), the bench grinder must be lifted and carried from the handling points marked on page 2.

5.2 Connection to Power Mains

Before commissioning, check that the rated mains voltage and mains frequency stated on the type plate match your power supply.

The grinder complies with protection class I and must therefore only be connected to sockets earthed according to specifications. Always install an RCD / GFCI with a maximum trip current of 30 mA upstream.

5.3 Installing workpiece support

Install workpiece support (10) as shown in illustrations A, page 2.

5.4 Fitting spark deflector and eye

preservers Install the spark deflector (13) and eye preservers (11) as shown in illustrations B, page 2.

5.5 Installing machine safely

Place the machine on a stable workbench. Ensure that the machine is securely seated. The machine can also be bolted down (screws not included in the scope of delivery). To do this, fasten the securing screws through the holes in the rubber feet. If a stand or wall bracket is used (see Accessories chapter): bolt down the machine.

5.6 Dust extraction connection (depending

on features) If your machine is not equipped with a dust extraction connection (7), fit an extraction device that is suitable for bench grinders. Inner diameter of extraction connection piece: 35 mm. Outer diameter of extraction connection piece: 41 mm. Before switching on the machine, ensure that the extraction device is connected and being used correctly.

Check the sanding discs before initial use. Test run A test run of approx. 5 min without load must be carried out before initial use. All persons must stay clear of the danger zone when this is performed.

6.1 Adjusting the workpiece support

Adjust the workpiece supports (10) frequently to compensate for wear of the sanding discs (4). The workpiece support must always be adjusted in such a way that the angle between the workpiece support and the tool is always greater than 85°. The distance between the workpiece support and grinding material must be as small as possible and never greater than 2 mm (see illustration C, page 2). If the sanding disc is so badly worn that the maximum distance of 2 mm can no longer be maintained, the sanding disc must be replaced.

6.2 Adjusting the spark deflector

Adjust the spark deflectors (13) regularly to compensate for wear on the grinding wheels (4). Release the 2 screws on the spark deflector and shift the spark deflector. The distance between the spark deflector and grinding wheel must be as small as possible and never greater than 2 mm (see illustration C, page 2). If the sanding disc is so badly worn that the maximum distance of 2 mm can no longer be maintained, the sanding disc must be replaced.

6.3 Switching on and off

Press the switch (14) (see illustrations D, page 2). I =Switch on 0 =Switch off Avoid inadvertent starts: always switch the tool off when the plug is removed from the mains socket or if there has been a power cut. Clean, check and perform maintenance work on the machine and guard devices regularly. Regularly clean the inside of the grinding wheels housing. The grinding wheels must be able to rotate freely within the housing. Disconnect the mains plug before starting any setting, cleaning, maintenance or repair work.

7.1 Sanding disc change

Use only original Metabo sanding discs. The permissible rotational speed specified on the sanding disc must be equal to or greater than the maximum idling speed specified on the identification plate of the machine. Sanding disc check: suspend the sanding disc on a thread. Knock lightly with a piece of hard wood. You will hear a clear tone if the sanding disc is in perfect condition. If you hear a clattering, dull or hollow sound, the grinding wheel is damaged. Do not use damaged sanding discs. Test run A test run of approx. 5 min without load must be carried out after the grinding wheel has been changed. All persons must stay clear of the danger zone when this is performed. Sanding disc: - Remove screws from safety cover (1) and take off cover (1). - Hold the sanding disc (4) firmly in position as shown. Alternative option: Insert a hexagonal wrench into the spindle and hold the spindle to prevent if from turning. Caution! Risk of injury! Wear protective gloves!
