Special Safety Instructions

General Safety Recommendations for grinding, sanding, wire brushing, polishing and cutting-off operations:

This power tool is intended to function as a sander, wire brush or polisher. 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.
Operations such as grinding or cutting-off are not recommended to be performed with this power tool. Operations for which the power tool was not designed may create a hazard and cause personal injury.
Do not use accessories which are not specifically designed and recommended by the tool manufacturer. Just because the accessory can be attached to your power tool, it does not assure safe operation.
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.
The outside diameter and the thickness of your accessory must be within the capacity rating of your power tool. Incorrectly sized accessories cannot be adequately guarded or controlled.
Threaded mounting of accessories must match the sanding spindle thread. For accessories mounted by flanges, the arbour hole of the accessory must fit the locating diameter of the flange. Accessories that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively and may cause loss of control.
Do not use a damaged accessory. Before each use inspect the accessory such as abrasive wheels for chips and cracks, backing pad for cracks, tear or excess wear, wire brush for loose or cracked wires. 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.
Wear personal protective equipment. Depending on application, use face shield, safety goggles or safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and workshop apron capable of stopping small abrasive or workpiece fragments. The eye protection must be capable of stopping flying debris generated by various operations. The dust mask or respirator must be capable of filtrating particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss.
Keep bystanders a safe distance away from work area. Anyone entering the work area must wear personal protective equipment. Fragments of workpiece or of a broken accessory may fly away and cause injury beyond immediate area of operation.
Hold the power tool by the insulated gripping surfaces only when performing an operation where the accessory may contact hidden wiring or its own cord (for SE 17-200 RT). Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and shock the operator.
Position the cord clear of the spinning accessory. If you lose control, the cord may be cut or snagged and your hand or arm may be pulled into the spinning accessory.
Never lay the power tool down until the accessory 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 it at your side. Accidental contact with the spinning accessory could snag your clothing, pulling the accessory into your body.
Regularly clean the power tool’s air vents. The motor’s fan will draw the dust inside the housing and excessive accumulation of powdered metal may cause electrical hazards.
Do not operate the power tool near flammable materials. Sparks could ignite these materials.
Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock.

Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged sanding wheel, backing pad, brush or any other accessory. Pinching or snagging causes rapid stalling of the rotating accessory which in turn causes the uncontrolled power tool to be forced in the direction opposite of the accessory’s rotation at the point of the binding. For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel that is entering into the pinch point can dig into the surface of the material causing the wheel to climb out or kick out. The abrasive wheel may either jump toward or away from the operator, depending on direction of the disc’s movement at the point of pinching. Abrasive wheels may also break under these conditions. Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions and can be avoided if suitable precautionary measures are taken as described below.

Maintain a firm grip on the power tool and position your body and arm to allow you to resist kickback forces. Always use auxiliary handle, if provided, for maximum control over kickback or torque reaction during start-up. The operator can control torque reactions or kickback forces, if proper precautions are taken.
Never place your hand near the rotating accessory. Accessory may kickback over your hand.
Do not position your body in the area where the power tool will move if kickback occurs. Kickback will propel the tool in direction opposite to the grinding wheel’s movement at the point of snagging.
Use special care when working 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.
Do not attach a saw chain woodcarving blade or toothed saw blade. Such blades create frequent kickback and loss of control.

Safety Warnings Specific for Sanding

Operations:

Do not use excessively oversized sanding disc paper. Follow manufacturers recommendations when selecting sanding paper. Larger sanding paper extending beyond the sanding pad presents a laceration hazard and may cause snagging, tearing of the disc or kickback.

Safety Warnings Specific for Polishing

Operations:

Do not allow any loose portion of the polishing bonnet or its attachment strings to spin freely. Tuck away or shorten the loose attachment strings. Loose and spinning attachment strings can entangle your fingers or snag on the workpiece.

Safety Warnings Specific for Wire Brushing Operations:

Be aware that wire bristles are thrown by the brush even during ordinary operation. Do not overstress the wires by applying excessive load to the brush. The wire bristles can easily penetrate light clothing and/or skin.
If the use of a guard is recommended for wire brushing, do not allow any interference of the wire wheel or brush with the guard. Wire wheel or brush may expand in diameter due to work load and centrifugal forces.

Additional Safety Instructions:

WARNING – Always wear protective goggles.
Use elastic cushioning layers if they have been supplied with the grinding media and if required. Observe the specifications of the tool or accessory manufacturer! Accessories must be stored and handled with care in accordance with the manufacturer’s instructions. Ensure that accessories are installed in accordance with the manufacturer’s instructions. The tool continues running after the machine has been switched off. When sanding and working with the lambskin polishing disc with cord drive always work with the safety guard installed. Do not use separate reducing bushings or adapters to adapt tools with a large hole. The workpiece must lay flat and be secured against slipping, e.g. using clamps. Large workpieces must be sufficiently supported. If accessories with threaded inserts are used, the end of the spindle may not touch the base of the hole on the sanding tool. Make sure that the thread in the accessory is long enough to accommodate the full length of the spindle. The thread in the accessory must match the thread on the spindle. See page 3 and chapter 14. Technical Specifications for more information on the spindle length and thread. Damaged, eccentric or vibrating tools must not be used. A damaged or cracked side handle must be replaced. Never operate a machine with a defective side handle. Only use the machine if the protective cover is in place. Always guide the machine with both hands on the handles provided

Special safety instructions for mains powered machines:
Pull the plug out of the socket before making any adjustments, changing tools, carrying out maintenance or cleaning.
Before connecting the mains plug, make sure that the machine is switched off.
Use of a fixed extractor system is recommended. Always install an RCD with a maximum trip current of 30 mA upstream. If the angle grinder is shut down via the RCD, it must be checked and cleaned. See Chapter 9. Maintenance.

Special safety instructions for cordless machines:
Remove the battery pack from the machine before making any adjustments, changing tools, maintaining or cleaning. Make sure that the tool is switched off before fitting the battery pack.

Reducing dust exposure

Some of the dust created using this power tool may contain chemicals known to cause cancer, allergic reaction, respiratory disease, birth defects or other reproductive harm. Some of these substances include: lead (in paint containing lead), mineral dust (from bricks, concrete etc.), additives used for wood treatment (chromate, wood preservatives), some wood types (such as oak or beech dust), metals, asbestos. The risk from exposure to such substances will depend on how long you or bystanders are being exposed. Do not let particles enter the body. Do the following to reduce exposure to these substances: ensure good ventilation of the workplace and wear appropriate protective equipment, such as respirators able to filter microscopically small particles. Observe the relevant guidelines for your material, staff, application and place of application (e.g. occupational health and safety regulations, disposal). Collect the generated particles at the source, avoid deposits in the surrounding area. Use suitable accessories for special work (see chapter 11.), thus less particles enter the environment in an uncontrolled manner. Use a suitable extraction unit.

Reduce dust exposure with the following measures:

Do not direct the escaping particles and the exhaust air stream at yourself or nearby persons or on dust deposits.
Use an extraction unit and/or air purifiers
Ensure good ventilation of the workplace and keep clean using a vacuum cleaner Sweeping or blowing stirs up dust
