21. NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Do not leave tool until it comes to a complete stop. 22. REPLACEMENT PARTS. When servicing, use only identical replacement parts. 23. POLARIZED PLUGS. To reduce the risk of electric shock, this equipment has a polarized plug (one blade is wider than the other). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install the proper outlet. Do not change the plug in any way. VOLTAGE WARNING: Before connecting the tool to a power source (receptacle, outlet, etc.) be sure the voltage supplied is the same as that specified Table 1: Minimum gage for cord on the nameplate of the tool. A power source with voltage greater than that specified for the tool can result in SERIOUS INJURY to the user- as well as damage to the tool. If in doubt, DO NOT PLUG IN THE TOOL. Using a power source with voltage less than the nameplate rating is harmful to the motor. USE PROPER EXTENSION CORD. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Table 1 shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.

AWG 16 16 14 16 14 12 16 14 12 12 Not Recommended Specific safety rules DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to portable cut-off safety rules. If you use this tool unsafely or incorrectly, you can suffer serious personal injury. 1. Wear hearing protection during extended period of operation. 2. Use only wheels having a maximum operating speed at least as high as "No Load RPM" marked on the tool's nameplate. Use only fiberglass-reinforced cut-off wheels. 3. Check the wheel carefully for cracks or damage before operation. Replace cracked or damaged wheel immediately. Run the tool (with guard) at no load for about a minute, holding tool away from others. If wheel is flawed, it will likely separate during this test. 4. Secure the wheel carefully. 5. Use only flanges specified for this tool. 6. Be careful not to damage the spindle, flanges (especially the installing surface) or bolt. Damage to these parts could result in wheel breakage. 7. Do not operate the tool without guards in place. Check wheel guard for proper closing before each use. Do not operate the tool if wheel guard does not move freely and close instantly. Never clamp or tie the wheel guard into the open position. 8. Hold the handle firmly. 9. Keep hands away from rotating parts. 10. Make sure the wheel is not contacting the workpiece before the switch is turned on. 11. Before using the tool on an actual workpiece, let it run for a while. Watch for vibration or wobbling that could indicate poor installation or a poorly balanced wheel. 12. Watch out for flying sparks when operating. They can cause injury or ignite combustible materials. 13. Remove material or debris from the area that might be ignited by sparks. Be sure that others are not in the path of the sparks. Keep a proper, charged fire extinguisher closely available. 14. Use the cutting edge of the wheel only. Never use side surface. 15. Do not attempt to keep the trigger in the ON position. 16. If the wheel stops during operation, makes an odd noise or begins to vibrate, switch off the tool immediately. 17. Turn off the tool and wait for the wheel to stop before moving workpiece or changing settings. 18. Do not touch the workpiece immediately after operation; it is extremely hot and could burn your skin. 19. Store wheels in a dry location only. SAVE THESE INSTRUCTIONS. WARNING: MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury. 3 ENGLISH
