Special Safety Instructions

Safety Warnings Common for Grinding, Sanding, Wire Brushing, Pol-ishing or Abrasive Cutting-Off Operations:

• a ) This power tool is intended to function as a sander 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.
• b ) This electric power tool is not suitable for grinding, wire brushing, and cutting-off operations. Operations for which the power tool was not designed may create a hazard and cause personal injury.
• c ) Do not use accessories which are not specif-ically designed and recommended by the tool manufacturer. Just because the accessory can be attached to your power tool, it does not assure safe operation.
• d ) 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.
• e ) 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.
• f ) The arbour size of wheels, flanges, backing pads or any other accessory must properly fit the spindle of the power tool. Accessories with arbour holes that do not match the mounting hard-ware of the power tool will run out of balance, vibrate excessively and may cause loss of control.
• g ) Do not use a damaged accessory. Before each use inspect the accessory such as abra-sive 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.
• h) Wear personal protective equipment. Depending on application, use face shield, safety goggles or safety glasses. As appro-priate, wear dust mask, hearing protectors, gloves and workshop apron capable of stop-ping 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 filtering particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss.
• i) 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.
• j ) Hold power tool by insulated gripping surfaces only, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and shock the oper-ator.
• k) Position the cord clear of the spinning acces-sory. If you lose control, the cord may be cut or snagged and your hand or arm may be pulled into the spinning accessory.
• I ) 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.
• m ) 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.
• n ) 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.
• o ) Do not operate the power tool near flam-mable materials. Sparks could ignite these mate-rials.
• p) 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 rotating 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 wheel may either jump toward or away from the operator, depending on direction of the wheel’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 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. Always use the auxiliary handle, if provided, for maximum control over kickback or torque reaction during start-up. The operator can control torque reactions or kick-back forces, if proper precautions are taken.

• b) Never place your hand near the rotating accessory. Accessory may kickback over your hand.

• c) Do not position your body in the area where power tool will move if kickback occurs. Kickback will propel
  the tool in direction opposite to the wheel’s move-ment at the point of snagging.

• d) 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.

• e) 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:

• a) Do not use excessively oversized sanding disc paper. Follow manufacturers recommen-dations when selecting sanding paper. Larger sanding paper extending beyond the sanding pad presents a laceration hazard and may cause snag-ging, tearing of the disc or kickback.

Safety Warnings Specific for Polishing:

• Loose parts on the polishing guard, especially the fastening cords, are not permitted. Tuck away or shorten the fastening cords. Loose, spinning fastening cords may make contact with your fingers or become caught in the workpiece.
• Use elastic cushioning layers if they have been supplied with the abrasive 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 instruc-tions.
• Ensure that accessories are installed in accord-ance 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 hand protection guard installed.
• Do not use separate reducing bushings or adapters to adapt tools with a large hole.
• The tool must lay flat and be secured against slip-ping, 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 grinding 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 2 and chapter 14 Technical Specifica-tions for more information on the spindle length and thread.
• For your own protection and for the protection of your power tool pay atten-tion to all parts of the text that are marked with this symbol!
• Always wear protective goggles.
• During machining, of metals in particular, conductive dust can form deposits inside the machine. This can lead to the transfer of electrical energy onto the machine housing. This can mean a temporary danger of electric shocks. This is why it is necessary when the machine is running to blow compressed air through the rear ventilation slots of the machine regularly, frequently and thoroughly. Here, the machine must be held firmly.
• We recommend using a stationary extractor system and connecting a residual current circuit-breaker (FI) upstream. When the machine is shut down via the
• FI circuit-breaker, it must be checked and cleaned. See chapter 9 Cleaning for more information on cleaning the motor.
• 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 conjunc-tion with additives for wood conditioning (chro-mate, wood preservative). Material containing asbestos must only be treated by specialists.
• Where the use of a dust extraction device is possible it shall be used.
• The work place must be well ventilated.
• The use of a dust mask of filter class P2 is recommended.
• Follow national requirements for the materials you want to work with.
• Materials that generate dusts or vapours that may be harmful to health (e.g. asbestos) must not be processed.
• When working in dusty conditions, ensure that ventilation openings are not blocked. If it becomes necessary to remove dust, first disconnect the power tool from the mains supply (use non-metallic objects) and avoid damaging internal components.
• Damaged, eccentric or vibrating tools must not be used.
• Connect a FI circuit-breaker with max. release current (30 mA) upstream when using the machine outdoors!
• Pull the plug out of the socket before making any adjustments, converting or servicing the machine.
• A damaged or cracked additional handle must be replaced. Never operate a machine with a defec-tive additional handle.
• A damaged or cracked hand guard must be replaced. Never operate a machine with a defec-tive hand guard.
