Remove any accessories from spindle. 2. Thread flange and nylon washer onto spindle. Attach guard and grinding wheel using Fig. 4 to determine type and order of assembly (See "Installing, Adjusting, and Removing the Guard" for attaching guard). NOTE: When installing Type 27 or Type 29 grinding wheels, position wheel nut according to wheel thickness. Position the guard in the location which offers best control and guard protection. For operating zones that provide maximum protection for the operator, see "Grinding". NOTE: When selecting Type 11 grinding cup wheels, the guard’s skirt should be adjusted so that no more than 1/8" of the wheel extends beyond the guard. 3. To tighten, press in the spindle lock button while turning wheel or disc nut clockwise using the spanner wrench provided. 4. To remove grinding wheel and guard, unplug tool and reverse procedure.

WARNING! Grinding and cut-off wheels should be protected from: • wetness and extreme humidity • any type of solvent • extreme changes in temperature • dropping and bumping Grinding and cut-off wheels should be stored: • in an organized way so wheels can be removed without disturbing or damaging other wheels • with their safety information Grinding and cut-off wheels should NOT be: • dropped • rolled • bumped If any wheel is dropped, rolled, bumped, subjected to extreme changes in temperature, or has come into contact with solvents or wetness, discard wheel immediately. Troubleshooting Deep scratches and circular marks can result from: • Uneven pressure • Using a partially glazed wheel - especially on aluminum applications • Dirt or loose metal on the workpiece • Failure to constantly move across surface Bluish discoloration of metal surface indicates: • Excessive heat caused by circular motion in a small area • Excessive pressure • Use of worn out or glazed wheels Inspecting Wheels Always handle wheels carefully to avoid damage. Before installing any wheel, always inspect it for cracks. If wheel is cracked, discard it to prevent others from using it. page 8 Selecting Wheels 2. If you have just installed a grinding wheel or are just beginning a period of work, test the wheel by letting it spin for one minute before applying it to the workpiece. Only use wheels with Maximum Safe Operating Speed rated at or above the RPM listed on the “WARNING” section of the tool's nameplate. This speed is based on the strength of the wheel, allowing for a reasonable measure of safety. It is not meant to imply a best or most efficient operating speed. Do not exceed the Maximum Safe Operating Speed. WARNING! NOTE: Out-of-balance wheels can mar workpiece, damage the tool, and cause stress to wheel that may cause wheel failure. 3. Firmly grasp rear handle and side handle before starting and while using tool. Allow wheel to come to full speed before starting to grind. 4. When grinding, hold tool at a 5o to 15o angle as shown, using constant pressure for a uniform finish (Fig. 6). Too great an angle causes too much pressure on small areas which may gouge or burn work surface. Grinding is the cutting action of thousands of abrasive grains on the face of a grinding wheel. When grinding metals such as steel and iron, choose an aluminum oxide grinding wheel. Select a silicon carbide grinding wheel for stone and concrete. Use cotton reinforced wheels for non-ferrous metals. Type 27 reinforced 1/8" cut-off wheels are suited for small cut-off and shallow notching operations only. Grinding (Fig. 5 & 6) WARNING! To reduce the risk of injury when grinding: • ALWAYS hold the tool firmly with both hands using the handles provided; before and during grinding • NEVER allow the wheel to bind • NEVER use a wheel that has been dropped • NEVER bang grinding wheel onto work • NEVER grind without proper safety equipment Using Type 27 Cut-Off Wheels (Fig. 7) Fig. 6 Hold at a 5° to 15° angle 5. Control pressure and surface contact between wheel and work- piece. Too much pressure slows cutting speed. A Type 27 guard must be installed when using a Type 27 cutoff wheel to provide maximum protection for the operator if the wheel should break. WARNING! To reduce the risk of injury when grinding, ALWAYS use the proper guard. ALWAYS properly install the guard. WARNING! Type 27 cut-off wheels are only suited for small cut-off and shallow notching operations. 1. Firmly grasp rear handle and side handle before starting and while using tool. Allow wheel to come to full speed before starting. 2. When using a cut-off wheel, hold tool as shown, using only the 1. Dependi...
