GRINDING WHEEL INSPECTION, REMOVAL, AND
INSTALLATION
DANGER!
Be sure to unplug the power cord from the outlet before attaching or removing the grinding
wheel from the tool. Accidental starting of the motor may cause bodily injury.
WARNING!
Be sure to securely tighten the flange assembly and all loose screws before testing the unit.
Please allow the grinding wheel to do the work. It is not necessary to apply more force onto
the machine than the force created by the weight of the machine itself. Applying excessive
force may damage the grinding wheel and cause premature failure of the bearings and
gears. Such action may decrease the rotation speed of the of the motor which reduces the
efficiency of the dust suction, because its power is driven by the spindle.
INSPECTING THE GRINDING WHEEL
1. If you are reinstalling the grinding wheel, check the welds on the diamond segments
for cracks.
2. Check the diamond segments for even wear.
3. The grinding wheel should be replaced if you find a crack in the weld or if the diamond
segments are worn down and below the brush assembly.
NOTE: The Alpha
®
26mm arbor grinding wheel, drive plate adapter and spring loaded flange
assembly are designed and engineered to work together. This design eliminates the
need for adjusting the grinding wheel height as the diamond segments wear.
