Safety instructions for angle grinder

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.

Safety Warnings Common for Grinding Operations

■ This power tool is intended to function as a grinder tool. 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.
■ Operation such as polishing, sanding and abrasive 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 grinder 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. If 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.
  ■ 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 rotating wheel, backing pad 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.

• 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 power tool will move if kickback occurs. Kickback will propel the tool in direction opposite to the 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 Grinding Operations

■ 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.
■ The grinding surface of centre depressed wheels must be mounted below the plane of the guard lip. An improperly mounted wheel that projects through the plane of the guard lip cannot be adequately protected.
■ 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 wheel fragments, accidental contact with wheel and sparks that could ignite clothing.
■ Wheels must be used only for recommended applications.
■ Always use undamaged wheel flanges that are of correct size and shape for your selected wheel. Proper wheel flanges support the wheel thus reducing the possibility of wheel breakage.
- Do not use worn down wheels from larger power tools. Wheel intended for larger power tool is not suitable for the higher speed of a smaller tool and may burst.

Additional safety instructions

■ Use suitable detectors to detect concealed power supply cables or consult your local supply company. Contact with electric cables may result in a fire and/or electric shock. A damaged gas pipe may cause an explosion. Cutting into a water pipe will cause damage to property or may cause an electric shock.

■ When working, hold the power tool firmly with both hands and ensure that you have a secure footing. The power tool is controlled more securely if held with both hands.
- Secure the workpiece. A workpiece is held more securely in a clamping device than by hand.
■ Dust released from materials, such as lead paints, some types of wood, minerals and metal, may be hazardous to the operator or people in the vicinity. Inhaling or touching such dust may result in respiratory diseases and/or allergic reactions.
– Ensure the workplace is well ventilated.
- If possible, use external dust extraction.
- It is recommended to wear a respirator mask belonging to filter class P2.
■ Do not work on materials which release hazardous substances (e.g. asbestos).
■ Use only original batteries with the voltage indicated on the type plate of your power tool. The use of other batteries, e.g. imitations, reconditioned batteries or other makes, increases the risk of injury and damage to property by exploding batteries.

Safety instructions for handling batteries

■ Do not open the battery. Short-circuiting hazard!
■ Protect the battery against heat, including prolonged sunshine, fire, water and moisture. Explosion hazard!
■ A damaged or incorrectly used battery may result in the emission of fumes. Ensure a supply of fresh air and consult a doctor in the event of any physical complications. The fumes may irritate the respiratory tracts.
- Liquid may leak out of the battery if the battery is incorrectly used. Avoid contact with such liquid. If contact accidentally occurs, rinse with water. If liquid contacts eyes, seek medical attention. Liquid discharged from the battery may cause irritation or burns.
■ Use FLEX rechargeable batteries only in connection with FLEX tools and FLEX accessories. Only in this way is the rechargeable battery protected against dangerous overloads.

■ Recharge batteries only with chargers recommended by the manufacturer. A charger that is suitable for one type of battery may create a fire hazard when used with another battery.
■ The battery may be damaged by pointed objects such as e.g. nails or screwdrivers or by external application of force. This may give rise to an internal short circuit, causing the battery to burn, smoke, explode or overheat.

Special safety instructions

■ The mains voltage and the voltage specifications on the rating plate must correspond.
■ Do not press the spindle lock until the grinding tool stops.

Noise and vibration
