Installing or removing wheel guard
WARNING:
When using a depressed center
wheel, flap disc, flex wheel or wire wheel brush,
the wheel guard must be fitted on the tool so that
the closed side of the guard always points toward
the operator.
WARNING:
When using an abrasive cut-off
/ diamond wheel, be sure to use only the special
wheel guard designed for use with cut-off wheels.
WARNING:
When installing a wheel guard, be
sure to tighten the screw securely.
For tool with locking screw type
wheel guard
Mount the wheel guard with the protrusions on the wheel guard
band aligned with the notches on the bearing box. Then rotate
the wheel guard to such an angle that it can protect the opera-
tor according to work. Be sure to tighten the screw securely.
To remove wheel guard, follow the installation proce-
dure in reverse.

Installing or removing depressed
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.
WARNING:
Be sure to tighten the lock nut
with the lock nut wrench while pressing the shaft
lock.
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 wheel/disc on the inner flange and screw the lock
nut with its protrusion facing downward (facing towards
the wheel).

fixed to the spindle with the lock nut. If the wheel
does not revolve with the spindle (i.e., if the
only wheel revolves), mount the lock nut on the
depressed center wheel or flap disc with the pro-
trusion of the lock nut upward. Depending on the
wheel thickness, the only wheel may revolve because
the lock nut cannot fix the wheel due to the height of
protrusion.
Installing or removing flex wheel
Optional accessory
WARNING:
flex wheel is on the tool. Wheel can shatter during
use and guard helps to reduce chances of personal
injury.
