center wheel or flap disc

Optional accessory

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.

WARNING:

 

Make sure that the mounting part 

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.

Fit the depressed center wheel / flap disc on the inner 

flange and screw the lock nut onto the spindle.
