SAFETY

SAFETY WARNINGS

Work area

• Keep work area clean and well lit. Cluttered and dark areas invite accidents.
• 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.
• Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical safety

• 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.
• 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.
• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
• Do not abuse the cord. 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.
• 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.
• 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.

• 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 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 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 could give the operator an electric shock.
• 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 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.

Other Safety Instructions for all Operations

Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged rotating wheel. Pinching or hanging causes rapid stalling of the rotating accessory which in turn forced the tool Power out of control in the opposite direction of rotation of the accessory to the point of seizing.
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 jumps or expulsion of the grinding wheel. The wheel can jump towards the operator or by moving away, as the direction of movement of the grinding wheel at the point of pinch. Abrasive wheels may also break under these conditions. Kickback is the result of misuse of the tool and / or procedures or conditions incorrect operation and can be avoided by taking proper precautions specified below.

• a) Maintain firmly the power tool and position your body and arm for you allow to resist kickback forces. Always use auxiliary handle, where applicable, for maximum control of kickback or torque reaction during startup. The operator can control the reaction torques or forces rebound, if precautions are taken.
• b) Never place your hand near the rotating accessory. The accessory can perform a bounce on your hand.
• c) Do not place you in the area where power tool will move if kickback. The rebound pushes the tool in the opposite direction to movement of the wheel in point hooking.
• d) Take special care when working corners, sharp edges etc.
  Avoid twists and snaps of the accessory. Corners, edges or sharp twists tend to hang the rotating accessory and cause loss of control or kickback.
• e) Do not attach a saw chain, blade wood carving saw chain or toothed saw blade. Such blades cause frequent rebounds and control losses.

Additional Safety Instructions for Sanding Operations

Set specific security guard for sanding

• a) Do not use sandpaper too oversized for sanding discs. Follow manufacturers’ recommendations when selecting sanding paper. More abrasive paper extending beyond the sanding pad presents a laceration hazard and may cause a crash, tearing of the disc or kickback.

WARNING Symbols

• WARNING! To reduce the risk of injury, user must read instruction manual.
• Always wear ear protection.
• Always wear safety goggles.
• Always wear a breathing mask.
• In accordance with essential applicable safety standards of European directives.

Machine-related safety instructions

• Harmful/toxic dust can be produced during your work (e.g. lead-containing paint, some types of wood and metal). Contact with this dust, especially inhaling it, can represent a hazard for operating personnel or persons in the vicinity. Comply with the safety regulations that apply in your country. Connect the electric power tool to a suitable extraction system.
  • To protect your health, wear a P2 protective mask.
• Use a residual current protective device when metal grinding, as well as when the operation of the power tool in a wet environment cannot be avoided. In the event of an electric shock, the protective switch protects you against life-threatening current through the body.
• Clean work equipment soaked in oils, for example sanding pad or polishing felt, with water and allow to dry. Work equipment soaked in oil may combust spontaneously.
• Attention: Risk of fire! Avoid overheating the grinding material and the sander. Always empty the dust container before taking a break. Swarf in the filter bag or filter of the mobile dust extractor may self-ignite in unfavourable conditions such as flying sparks when grinding metals. Particular danger exists if the swarf is mixed with paint, polyurethane residue or other chemical materials and the grinding material is hot after long periods of work.
• Always use original sanding pads. Foreign pads are not suitable for the speed of the sander and may break.
• If the power tool is dropped or falls, check for damage to the machine and sanding pad. Remove the sanding pad for closer inspection. Repair damaged parts before using again. Broken sanding pads and damaged machines can cause injuries and machine instability.
  • Always wear protective goggles to protect against sanding hazards.

Mixed dust containing metal and sanding damp surfaces
With mixed dust containing metal (such as dust resulting from paint sanding in the automotive field) and when sanding damp surfaces, the following measures must be observed for reasons of safety:

• Connect the machine to a suitable dust extractor.
• Regularly blow out the motor housing of the machine to remove dust deposits.

Intended use
