13) Install the weight/belt cover to the main frame
and secure with the wing-type nuts. Determine that all
safety related decals affixed to the weight/belt guard
are fully readable. If any decal is hot fully readable,
replace with a factory approved, replacement part
only.
13) If the machine is to be used immediately, determine
the master switch located on the operator handle is in
the oFF position and that the starter control grip is in
the oFF position before reconnecting the Floor Grinder
to the power source.
REPLACING THE LORD® TYPE ELASTOMERIC
MOUNTS ON THE MULTI-ACCESSORY DISC
Application: SG87SH SURFACE SHARK
Lord® type elastomeric rubber mounts are utilized
to allow each multi-accessory disc to maintain full
contact with the work surface. The rubber mounts
afford a constant flex rate for the multi-accessory disc
throughout its service life. The rubber compound is
resistive to the effects of ultraviolet radiation and most
common chemicals encountered when operating the
Floor Grinder .
During the manufacturing process, the rubber mounts
are pressed into specially machined cavities in the
disc mounting plate. under normal usage and job
applications, the Lord® type rubber mounts will deliver
appropriate performance for the expected service life
of the Floor Grinder. however, an attachment mounted
in the multi-accessory disc that directly strikes a vertical
floor obstruction with sufficient impact force can cause
one or more of the mounts to become separated from
the mounting plate. This occurrence will not allow
the multi-accessory disc to maintain full contact with
the work surface. This occurrence is also intended to
protect the v-belt and bearings from costly damage
and the operator from an impact force that could cause
personal injury.
Tools Required:
1 each, 5/16 Allen wrench.
2 each, 5/8 wrenches.
1 each, arbor press of sufficient capacity and stability.
1each, suitable length of 3/4 inch diameter steel rod.
1 each, suitable section of 1-1/2 inch inside diameter
steel tubing.
Parts Required:
Part# MJ-6250-2 Elastomeric Mount (as required).
1 container each: Part# M80 Installation Lubricant (or
approved equivalent).
1) Disconnect the Floor Grinder from the extension
cord or power source bEFoRE performing any service
related work.
2) Position the Floor Grinder on a suitable work surface
with the multi-accessory disc at a comfortable level.
3) Remove the wing-type nuts from the main frame.
While gripping the cutout in the external weight, slide
the weight/belt guard away from the electric motor
approximately 1 inch. This will release the cover from
the forward catch mechanism. Remove the weight/belt
guard from the main frame. Clean the inside of the belt
guard with an appropriate safety solvent. Check for
signs of wear and damage. Secure in a proper storage
area.
Observe all applicable safety precautions for the
solvent.
4) Tilt the Floor Grinder back until the operator handle
comes in contact with the surface. The Floor Grinder
may not be in a stable position in this configuration.
To minimize the possibility of property damage and/
or personal injury, apply an appropriate weight to the
handle to stabilize the Floor Grinder. FIGuRE 26. other
means can also be utilized to support the frame and
provide proper machine stability. Appropriate wheel
chocks are recommended. Follow the instructions for
this procedure as outlined in INSTALLING A MULTI-
ACCESSORY ATTACHMENT IN THE ALUMINUM
DISC.
5) utilizing the Allen wrench, remove the aluminum
multi-accessory disc (if still attached) from the Floor
Grinder.
6) utilizing the 9/16 inch wrenches, remove the cap
screws that retain the Lord® rubber mounts to both the
mounting plate and transmission shaft.
