Safety First - Always Grind Safely 1. Always handle and store abrasives in a careful manner. 2. Always visually inspect all abrasives before mounting for possible damage in transit, storage, or prior use. 3. Always “Ring Test” the wheel by tapping gently with a light metallic implement such as the handle of a screwdriver for light wheels, or Wooden or Plastic Mallet for heavier wheels. An undamaged wheel will give a clear tone. 4. Always make sure the operating speed established for the equipment does not exceed the wheel speed. 5. Always check mounting flanges for equal and correct diameter. 6. Always use mounting blotters when supplied with abrasives. 7. Always keep work rest properly adjusted within 1/8" (3mm) of wheel face. 8. Always direct grinding sparks downward and away from the face and body. 9. Always wear protective equipment such as, impact resistant safety glasses or goggles, full face shield, safety shoes, arm guards, leather gloves and apron must be used for operator protection for all grinding operations. Always wear a respirator to avoid inhalation of dust particles. 10. Always use a safety guard covering at least one-half of the wheel diameter. 11. Always allow newly mounted wheels to run at operating speed, with the guard in place, for at least one minute before starting to grind. 12. Always observe all safety recommendations supplied by the Equipment Manufacturer. DO NOT attempt the following: 1. Do Not use a wheel that has been dropped. 2. Do Not use wheels that have been soaked in water 3. Do Not use wheels without guards for grinding or cutoff work. 4. Do Not force a wheel onto the spindle or alter the hole of size the wheel. 5. Do Not use a wheel that fits the arbor too loosely. 6. Do Not exceed maximum operation speed established for the wheel. 7. Do Not use dirty, nicked, warped or sprung mounting flanges. 8. Do Not tighten the mounting nut excessively. 9. Do Not grind on the side of the wheel unless the wheel is specifically designed for that purpose. 10. Do Not start machine unless the machine guard is in place. 11. Do Not jam work into the wheel. Let the wheel do the work. 12. Do Not apply excessive pressure. 13. Do Not stand directly in front of a grinding wheel whenever a grinder is started. 14. Do Not grind near flammable material. 15. Do Not grind or cut material for which the wheel is not designed. 16. Do Not flat grind. Minimum grinding angle is 15°. 17. Do Not use relieved or recessed flanges with threaded hole cup wheels, cone or plugs. 18. Never use a wheel or a disc that has been dropped, chipped, mishandled or appears defective.
Type 1, Abrasive Cut-Off Wheels Size: 4" x 1/16" x 5/8" (5 pc./pk.) Max. RPM: 18,000 Grade: A46T2FG Use Tips for Firepower Cut-Off Wheels: 1. When using cut-off wheels, a soft pressure should be used for initial contact with the workpiece - cutting should be done with even constant pressure. 2. For stationary cut-off machinery, it is important to have good stability and steadiness to prevent vibration. Also, the motor should be powerful enough to keep the cutting time as short as possible to prevent burning or discoloring the material 3. Material being cut or ground should always be clamped or securely positioned, especially in cutting-off operations. 4. Proper machine speed is essential for maximum efficiency. Low speed causes "jumping" of the disc., and can cause the circumference to wear unevenly. 5. Flat cut-off wheels can be brushed, if required.
Firepower Double Reinforced Cut-Off Wheels are designed for heavy duty cut-off jobs using circular saws, chop-saws and straight grinding machines. They ensure optimum effectiveness for dry applications on a broad range of ferrous and non-ferrous metals, soft ceramics, masonry materials, reinforced plastic and fiber glass. Most Firepower cut-off wheels are double reinforced with two layers of fiber glass.
