ASSEMBLY INSTRUCTIONS/OPERATIONS
5) Using a hammer, strike the wider side of the
mounting wedge with controlled, direct blows to
firmly seat the multi-accessory attachment into
the aluminum disc. Usually one or two direct
blows will be sufficient to properly retain the
attachment.
CAUTION
Do not apply excessive impact force to the
mounting wedge to cause splitting. Once the
multi-accessory attachment is seated in the
aluminum disc, further impact force on the
wedge will not increase the seating force.
CAUTION
Improper seating force created by an excessive
blow to the mounting wedge will not allow the
attachment to properly release from the
aluminum disc if direct contact with a foreign
object is made. Such occurrence can result in
property damage and/or personal injury. The
correct seating force for a specific job
application is that which is sufficient to retain
the attachment, yet still allows it to release from
the aluminum disc when direct contact with a
foreign object is made.
6) Determine that the multi-accessory attachment
is in full contact with the aluminum disc. If not in
proper contact, refer to REMOVING A MULTI-
ACCESSORY ATTACHMENT (not including
multi-segmented, dry diamond blades) FROM
THE COUNTERROTATING DISCS for proper
removal procedures.
7) Return the SURFACE GRINDER to its normal
operating position.
8) If the SURFACE GRINDER is powered by an
engine, reconnect the engine spark plug wire. If
powered by an electric motor and the machine is
to be used immediately, reconnect the extension
cord or SURFACE GRINDER to the power
source. Determine that the ON/OFF switch
located on the operator handle is in the OFF
position.

(not including multi-segmented, dry diamond discs)
FROM THE COUNTERROTATING DISCS.
Application: All Models.
Tools Required:
1 each, Small Hammer
1 each, Drift Punch or small, Pry Bar
DANGER
WHEN REMOVING A MULTI-ACCESSORY
ATTACHMENT FROM THE SURFACE GRINDER,
ALWAYS WEAR APPROPRIATE SAFETY
EYEWEAR AND APPAREL TO MINIMIZE THE
POTENTIAL FROM FLYING DEBRIS. FLYING
DEBRIS CAN RESULT IN PROPERTY DAMAGE
AND/OR PERSONAL INJURY.
1) If the SURFACE GRINDER is powered by an
engine, disconnect the spark plug wire. If powered
by an electric motor, disconnect the extension cord
or SURFACE GRINDER from the power source.
2) Tilt the SURFACE GRINDER back until the
operator handle comes in contact with the surface.
Follow the instructions for this procedure as outlined
in INSTALLING A MULTI-ACCESSORY
ATTACHMENT (not including multi-segmented, dry
diamond blades) IN THE COUNTERROTATING
DISCS.
3) The multi-accessory attachment can be
removed by both the use of a drift punch or small,
pry bar. If utilizing the drift punch, strike the narrow
end of the mounting wedge with controlled, direct
blows until the attachment is released from the
aluminum disc. If utilizing the pry bar, position the
bar between the aluminum disc and the attachment.
Use controlled, direct blows to the bar in order to
force the attachment loose from the aluminum disc.
