Installing or removing wheel guard
CAUTION:
• When using a depressed center grinding wheel/
Multi-disc, flex wheel, wire wheel brush, cut-off
wheel or diamond wheel, the wheel guard must be
fitted on the tool so that the closed side of the guard
always points toward the operator.
Mount the wheel guard with the protrusion on the wheel
guard band aligned with the notch on the bearing box.
Then rotate the wheel guard around 180 degrees. Be
sure to tighten the screw securely.
To remove wheel guard, follow the installation procedure
in reverse.

grinding wheel/Multi-disc is on tool. Wheel can
shatter during use and guard helps to reduce

Mount the inner flange onto the spindle. Fit the wheel/
disc on the inner flange and screw the lock nut onto the
spindle.
To tighten the lock nut, press the shaft lock firmly so that
the spindle cannot revolve, then use the lock nut wrench
and securely tighten clockwise.

Installing or removing diamond wheel
(optional accessory)
CAUTION:
• Always install the wheel guard before installing the
diamond wheel.
• When mounting the wheel ensure that the arrow
(indicating the direction of rotation) on the wheel is
pointing in the same direction as the arrow for rota-
tion provided on the tool.
Mount the inner flange onto the spindle so that the side
of the inner flange with the 7/8" diameter protrusion faces
the diamond wheel. Place the diamond wheel onto the
inner flange making sure the protrusion fits into the arbor
of the wheel. Use the lock nut to secure the wheel by
placing it on the spindle so that the flat side faces the
wheel and screw the lock nut onto the spindle. To tighten
the lock nut, press the shaft lock firmly so that the spindle
cannot revolve, then use the lock nut wrench and
securely tighten clockwise.
