Refer to all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all the instructions may result in electric shock, fire and/or serious injury. b) This power tool is not suitable for polishing or tasks using roughing discs, wire brushes, parting grinder discs and flap discs. 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 specifically designed and recommended by the tool manufacturer. The simple fact that an accessory can be attached to your power tool does not ensure 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 protected or controlled. f) The arbour size of routing tools, flanges, diamond cup wheels or any other accessory must properly fit the spindle of the power tool. Accessories with arbour holes that do not match the mounting hardware 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 use, always check accessories for splinters or cracks and check grinding wheels for cracks or signs of severe wear and tear. 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 a face shield, safety goggles or safety glasses. As appropriate, wear a 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 filtering particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss.

i) Keep bystanders a safe distance away from

your work area. Anyone entering the work area must wear personal protective equipment. Fragments of a workpiece or broken accessory may fly into the air and cause injury beyond the 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. A cutting accessory that comes in contact with a "live" wire may render exposed metal parts of the power tool "live" and give the operator an electric shock. k) 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.

I) Never lay the power tool down until the

accessory has come to a complete stop. The spinning accessory may catch 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 draws dust into the housing. o) Do not operate the power tool near flammable materials. Sparks could ignite these materials. p) Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock.

4.1 Kickback and Related Warnings

Kickback is a sudden reaction to a pinched or snagged routing or grinding tool or similar accessory. Pinching or snagging causes the rotating accessory to come to an abrupt halt, which in turn forces the uncontrolled power tool in the direction against the accessory’s rotation at the point of jamming. Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions. It 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, maximum control over kickback or torque reaction during start-up. The operator can control torque reactions or kickback forces, if proper precautions are taken. b) Never place your for 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 power tool in the direction against the accessory’s movement at the point of jamming. d) Use special care when working around corners, sharp edges etc. Avoid bouncing and snagging the accessory. The rotating accessory tends to jam around corners and sharp edges and also if bouncing occurs, thus causing 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.

4.2 Safety Warnings Specific for Routing

Operations: a) Use only routing tools that are recommended for your power tool and the specific guard designed for these routing tools. Routing tools that are not designed for use with the power tool cannot be guarded properly and are unsafe. b) The guard must be securely attached to the power tool and positioned so as to minimise exposure of the routing body to the operator and thus maximise safety. The guard helps to protect the operator from broken fragments, accidental contact with the routing body and sparks that could ignite clothing. c) Do not work on surfaces with exposed steel reinforcements or similar. Doing so may result in kickback or loss of control over the power tool. d) Before commissioning, check that the routing wheels can move freely. Clean these, if necessary. e) Do not use damaged routing wheels. f) Exercise particular caution when working on corners, edges and ledges. There is a risk here of kickback or damaging the router. g) Routing wheels have sharp edges and may be very hot after use. Caution! Risk of injury.

4.3 Safety Warnings Specific for Grinding

with Diamond Cup Wheels: a) Use only wheel types that are recommended for your power tool and the specific guard designed for the selected wheel. Wheels for which the power tool was not designed cannot be adequately guarded and are unsafe. b) The 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. The guard helps to protect the operator from broken fragments, accidental contact with the wheel and sparks that could ignite clothing. c) Wheels must be used only for recommended applications. d) Always use undamaged wheel flanges that are the correct size and shape for your selected accessories. The correct flanges support the accessories.
