GENERAL WARNINGS

All instructions concerning safety and the prevention of industrial accidents can be found in file SAFETY INSTRUCTIONS, that forms integral part of this documentation. This INSTRUCTION MANUAL only contains additional information that specifically explain how to use the machine

SPECIFIC USE

General safety instructions
This electrical tool is designed to operate as a grinder, grinding and abrasive cutting operations, metal brushing. Read all safety warnings, instructions, illustrations and specifications supplied with this electrical tool. Failure to respect all instructions shown below may cause electric shock, fire and/or serious accident. Sanding and polishing operations are not recommended with this electrical tool. Operations for which the use of the electrical tool is not provided for can create hazards and cause harm to personnel. Theuse of this tool for smoothing, metal brushing and polishing operations is not recommended. Its use for applications other than those for which it has been designed may lead to hazardous situations and cause injuries to people. Do not use accessories that are not specifically designed for the intended use of the tool or that have not been recommended by the manufacturer. The fact that an accessory can be fixed to the tool does not imply that it can be used safely. The rated speed of accessories must be at least equivalent to the maximum speed of the tool.

If operated at a greater speed than the rated one, accessories may break and cause the ejection of chips. The external diameter and thickness of accessories must be appropriate to guarantee the protection and safety of the tool. Accessories with incorrect dimensions cannot be adequately protected or controlled. The configuration of the cutting/grinding wheels or any other accessory mustperfectly adapt to the tool spindle. Accessories with holes that cannot be aligned with the fitting components on the tools will cause unbalance, excessive vibrations and may be difficult to control. Do not use an accessory if damaged. Before use, inspect all the accessories, like the abrasive cutting/grinding wheels, in order to verify that they are not cracked or splintered. If the tool or accessory has fallen, verify that they are not damaged and, if necessary, replace it with a new one. After inspecting or installing an accessory, move to a safe distance with any other person present and operate the tool at maximum speed without load for one minute. Damaged accessories generally break during this test period.

Wear personal protective equipment. According to the the application, use face shield, mask or safety goggles. According to the case, wear a dust mask, ear protection, gloves and a smock capable of stopping small abrasive fragments of the work piece. Eye protection must be able to stop flying bits produced from the different operations The dust mask or the respirator must be capable of filtering particles produced by your work. Prolonged exposure to high intensity noise can cause a loss of hearing. Keep the people present at a safety distance with respect to the work area. Anyone entering the work area must wear personal protection equipment. The fragments of the work piece or the broken accessories can fly off and cause injuries in the immediate vicinity of the work area. Keep the tool only for isolating gripping surfaces, while the operations are carried out in which the cutting accessory may be in contact with the hidden cables or with its cable. The contact between the cutting accessory and the cable “under voltage” can also put the exposed metal parts of the electrical tool “under voltage” and can cause an electrical shock for the operator.

Position the cable far from the rotation accessory. If control is lost, the cable can be cut or twisted and your hand or arm could be pulled into the rotation accessory. Never put the electrical tool back before the accessory has completely stopped. The rotation accessory can be pressed on the surface with the electrical tool put out of your control. Do not operate the electrical tool while carrying it at the side. Accidental contact with the rotation accessory can get your clothes entangled and attract the accessory towards you. Regularly clean the fan openings of the electrical tool. The motor fan will attract the dust into the housing; excess dust accumulation can cause electrical hazards. Do not operate the electrical tool in the proximity of flammable material. The sparks can ignite these materials. Do not use accessories that need liquid coolants. The use of water or other liquid coolants can cause electrocution or electrical shock

ADDITIONAL SAFETY WARNINGS FOR GRINDING AND ABRASIVE CUTTING OPERATIONS

Use only the type of cutting/grinding wheels recommended for your tool and the protection specifically designed for the selected cutting/grinding wheel. Cutting/grinding wheels not designed to be used with the tool cannot be adequately protected and are unsafe. The protection must be solidly fixed to the tool and placed in the safest position possible so as to minimise the potential risk of contact between the operator and cutting/grinding wheel. The protection is designed to protect operators from the ejection of fragments in case of breakage and from accidental contacts with the grinding wheel. Cutting/grinding wheels must be used for the recommended applications only. For example do not use the cutting side of the wheel for grinding operations. Abrasive cutting wheels may break because they are designed to be used for peripheral grinding operations and for the application of lateral forces. Always use the cutting/grinding wheels with undamaged flanges and verify that their shape and dimensions are appropriate for the selected cutting/grinding wheel. The purpose of flanges is to support the cutting/ grinding wheel and reduce the potential risk of breakage. Flanges forcutting wheels may be different from those of grinding wheels. Do not use grinding/cutting wheels that have been fitted on larger tools. These cutting/grinding wheels are unsuitable because of their higher speed as compared to that of smaller tools and could therefore cause explosions.

ADDITIONAL SAFETY WARNINGS FOR ABRASIVE CUTTING OPERATIONS

Do not “stall” the cutting wheel or apply an excessive pressure. Do not attempt to increase the cutting depth. The application of a high pressure on the cutting wheel increases the load and the risk of torsion and bending during cutting, with the consequent risk of rebound forces or breakage. Do not stand in line with the cutting/grinding wheel or behind it while it is rotating. When the cutting/grinding wheel moves away from the operator’s body during operation, the rebound force may push the revolving cutting/grinding wheel and the tool towards the operator. If the cutting/grinding wheel bends or the cutting operations stops for any reason, disconnect the tool from the power supply and keep it still until the cutting/grinding wheel has come to a full stop. Do not attempt to remove the cutting wheel while it is moving because this could produce a rebound force. Identify the cause of the problem and perform the necessary corrective actions to prevent the problem from reoccurring. Do not resume the cutting operation. Resume the cutting operation only when the cutting wheel has reached its maximum speed. The cutting wheel may stall, lift or produce a rebound force if the tool is restarted when the work piece is present. Always use appropriate supports for panels or large work pieces in order to minimisethe risk of interlocking and rebound forces. Large work pieces tend to bend because of their weight. Supports must therefore be placed under the work piece, close to the cuttingline and to the edge of the work piece on both sides. Pay particular attention when cutting “pockets” on existing walls or other areas with limited visibility. The projecting cutting wheel may cut gas or water pipes, electrical cables or other objects and thus produce a rebound force.

SPECIFIC SAFETY WARNINGS FOR METAL BRUSHING

Keep in mind that the brush, even during normal operation, emits metal bristles. Do not apply excessive force to the metal wires, by applying excessive force to the brush. The metal bristles can easily penetrate light clothing and/or hair. If use of protection for the metal brushing is recommended, do not allow any interference of the disc to the metal wires or of the brush with the protection. The disc with metal wires or the brush can expand in diameter due to the work load and centrifugal forces.

FURTHER HAZARD WARNINGS
Avoid having dust accumulated on the work station. The dust can easily ignite. A work piece can be safely locked in position only using an appropriate tightening device or a screw clamp and not just holding it with your hand. Adjust the protective earmuffs so as to impede a trail of sparks in the direction of the operator. Do not touch the rough and cut grinding wheels before they are cooled. Activate the locking key of the spindle only when the spindle is stopped. Otherwise, the electrical tool may suffer damages. Wear protective goggles
