WARNING:
When using a depressed center
wheel or flap disc, the wheel guard must be fitted
on the tool so that the closed side of the guard
always points toward the operator.

of the inner flange fits into the inner diameter of
the depressed center wheel / flap disc perfectly.
Mounting the inner flange on the wrong side may
result in the dangerous vibration.
Mount the inner flange onto the spindle.
Make sure to fit the dented part of the inner flange onto
the straight part at the bottom of the spindle.
