A guard or other part that is damaged should be properly repaired or replaced by an authorised service centre unless otherwise indicated in this instruction manual. Do not use the tool if the switch does not turn it on and off. 21. WARNING. The use of any accessory or attachment other than one recommended in this instruction manual may present a risk of personal injury. 22. HAVE YOUR TOOL REPAIRED BY A QUALIFIED PERSON. This electric tool complies with the relevant safety rules. Repairs should only be carried out by a qualified person using original spare parts, otherwise this may result in considerable danger to the user. 23. THROUGH POOR CONDITIONS OF THE ELECTRICAL MAINS, shortly voltage drops can appear when starting the EQUIPMENT. This can influence other equipment (e.g. blinking of a lamp). If the MAINS-IMPEDANCE Zmax < 0.34 OHM, such disturbances are not expected. 24. DO NOT USE SAW BLADES MANUFACTURED FROM HIGH SPEED STEEL. 25. KEEP THE FLOOR AREA AROUND THE MACHIN LEVEL, well maintained and free of loose material e.g. chips and cutoffs. 26. USE CORRECTLY SHARPENED SAW BLADES. Observe the maximum speed marked on the saw blade. Ensure that the machine is always fixed to a bench, whenever possible. Additional Safety Rules For Metal Cutter 1. Do not use grinding wheels. 2. Before operation, check the blade carefully for cracks or damage. Replace the cracked or damaged blade immediately to avoid the possible hazard. 3. Use correct size of saw blades. Always use the blades that are recommended by the manufacturer. 3. Never operate the product without the blade guard. 4. Hold the tool firmly during operating. Do not reach underneath the work. The guard can not protect you from the blade below the work. Do not attempt to remove cut material when blade is moving. 5. Never turn on the product when the blade touches the workpiece. 6. Do not lay the metal cutter down until the blade stops completely. 7. To prevent injury, be sure to unplug from the power source outlet before assembling, adjusting, or maintaining the tool. 8. Keep your hands away from the cutting area and the blade. Always hold the tool with one hand holding on the switch handle and the other hand holding on the auxiliary handle. 9. Adjust the cutting depth to the thickness of the workpiece. Less than a full tooth of the blade teeth should be visible below the workpiece. 10. Always use blades with correct size and shape (diamond vs. round) arbor holes. Blades that do not match the mounting hardware of the tool will run eccentrically, causing loss of control. 11. Do not use damaged or incorrect washers or bolts or it will cause the loss of control. 12. To avoid injury, if the power cable is damaged, do not change by yourself. Please contact a qualified engineering or local manufacturer to deal with. 13. When ripping always use a rip fence or straight edge guide. This improves the accuracy of cut and reduces the chance for blade binding. WARNING! For your own safety, read all these instructions before attempting to operate your product.

tool to cut wood, diamond, magnesium or magnalium workpiece. 15. Wear safety goggles and hearing protection during operation. 16. Check lower guard for proper closing before each use. Do not operate the saw if lower guard does not move freely and close instantly. Never clamp or tie the lower guard into the open position. If saw is accidentally dropped, lower guard may be bent. Raise the lower guard with the retracting handle and make sure it moves freely and does not touch the blade or any other part, in all angles and depths of cut. 17. Check the operation of the lower guard spring. If the guard and the spring are not operating properly, they must be serviced before use. Lower guard may operate sluggishly due to damaged parts, gummy deposits, or a build-up of debris. 18. Lower guard should be retracted manually only for special cuts such as ″plunge cuts″ and ″compound cuts.″ Raise lower guard by retracting handle and as soon as blade enters the material, the lower guard must be released. For all other sawing, the lower guard should operate automatically. 19. Always observe that the lower guard is covering the blade before placing saw down on bench or floor. An unprotected, coasting blade will cause the saw to walk backwards, cutting whatever is in its path. Be aware of the time it takes for the blade to stop after switch is released. 20. DO NOT USE THIS METAL CUTTER WITH THE SAW BLADE HELD UPSIDE DOWN IN A VISE. The saw is not designed for such use and cannot be used safely in that position. Special Safety Rules For Kickback 1. Causes and Operator Prevention of Kickback: ● Kickback is a sudden reaction to a pinched, bound or misaligned saw blade, causing an uncontrolled tool to lift up and out of the workpiece toward the operator. ● When the blade is pinched or bound tightly by the kerf closing down, the blade stalls and the motor reaction drives the unit rapidly back toward the operator. ● If the blade becomes twisted or misaligned in the cut, the teeth at the back edge of the blade can dig into the top surface of the workpiece causing the blade to climb out of the kerf and jump back toward operator. 2. Kickback is the result of tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below: ● Maintain a firm grip with both hands on the tool and position your body and arm to allow you to resist KICKBACK forces. KICKBACK forces can be controlled by the operator, if proper precautions are taken. ● When blade is binding, or when interrupting a cut for any reason, release the trigger and hold the tool motionless in the material until the blade comes to a complete stop. Never attempt to remove the tool from the work or pull the tool backward while the blade is in motion or KICKBACK may occur. Investigate and take corrective actions to eliminate the cause of blade binding.

All tools, hoses and packaging should be sorted, taken to the local recycling centre and disposed of in an environmentally safe way. Do not dispose of electrical appliances as unsorted municipal waste, use separate collection facilities. Contact your local government for information regarding the collection systems available. If electrical appliances are disposed of in landfills or dumps, hazardous substances can leak into the groundwater and get into the food chain, damaging your health and well-being. When replacing old appliances with new once, the retailer is legally obligated to take back your old appliance for disposal at least for free of charge. Disposal of discarded material shall be in accordance with local environmental regulations. Keep hands away from blade: Failure to keep your hands away from the blade will result in serious personal injury. WARNING! To reduce the risk of injury, user must read instruction manual. Wear safety goggles. Wear ear protection. Wear a breathing mask. ● When restarting a tool in the workpiece, center the saw blade in the kerf and check that saw teeth are not engaged into the material. If saw blade is binding, it may walk up or KICKBACK from the workpiece as the tool is restarted. ● Support large panels to minimize the risk of blade pinching and KICKBACK. Large panels tend to sag under their own weight. Supports must be placed under the panel on both sides, near the line of cut and near the edge of the panel. ● Do not use dull or damaged blade. Unsharpened or improperly set blades produce narrow kerf causing excessive friction, blade binding and KICKBACK. Keep blade sharp and clean. Gum and pitch hardened on blades slows tool and increases potential for kickback. Keep blade clean by first removing it from tool, then cleaning it with gum and pitch remover, hot water or kerosene. Never use gasoline. ● Blade depth and bevel adjusting locking levers must be tight and secure before making cut. If blade adjustment shifts while cutting, it may cause binding and KICKBACK. ● ALWAYS hold the tool firmly with both hands. NEVER place your hand or fingers behind the tool. If kickback occurs, the tool could easily jump backwards over your hand, leading to serious personal injury. ● Never force the tool. Forcing the tool can cause uneven cuts, loss of accuracy, and possible kickback. Push the tool forward at a speed so that the blade cuts without slowing. ● Blade depth and bevel adjusting locking levers must be tight and secure before making cut. If blade adjustment shifts while cutting, it may cause binding and kickback.
