not tighten properly.
TO INSTALL
See Figure 5.
n Unplug the cut-off machine.
n Inspect the replacement wheel for defects such as cracks,
chipping, and correct speed rating. If defects are found
or the speed rating is not greater than 3,900 rpm, do not
use. Select another wheel.
�n Clean debris from the inner washer and inner flange.
�n Place new wheel over spacer, then place both on wheel
arbor against inner flange.
�n Clean outer flange, then align flats with flats on wheel
arbor and slide it onto arbor until it is flush against
wheel.

arbor, then insert the hex head bolt into the threaded end
of the wheel arbor.
�n Start threads and turn bolt clockwise to snugly tighten.
