WARNING:
When servicing, use only identical Ryobi replacement
parts. Use of any other parts may create a hazard or
cause product damage.
WARNING:
Always wear eye protection with side shields marked to
comply with ANSI Z87.1. Failure to do so could result in
objects being thrown into your eyes resulting in possible
serious injury.

GENERAL MAINTENANCE

Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating oils, etc., come in contact
with plastic parts. Chemicals can damage, weaken or
destroy plastic which may result in serious personal
injury.
WARNING:
Always disconnect the bench grinder from the power
source before performing any assembly or adjustment.
Failure to do so could result in accidental starting
resulting in possible serious personal injury.

WHEEL REPLACEMENT

See Figure 12, page 15.
If you must replace a grinding wheel, be sure to obtain one
with a safe rated speed at least as high as the "no load
speed" RPM marked on the data plate of the grinder and
which is marked to comply with ANSI B7.1.
To replace the grinding wheel.
 Unplug the grinder.
 Remove the wheel cover by loosening the screws.
 Loosen the wheel nut in a clockwise direction for the left
side and a counterclockwise direction for the right side.
 Remove the outer flange and grinding wheel.
 To install a new grinding wheel, reverse the above
procedure.
NOTE: Be sure the grinding wheel and outer flange are
properly seated on the spindle shaft.

MAINTENANCE

Electric tools used on fiberglass material, wallboard, spackling
compounds, or plaster are subject to accelerated wear and
possible premature failure because the fiberglass chips and
grindings are highly abrasive to bearings, brushes, commuta-
tors, etc. Consequently, we do not recommended using this
tool for extended work on these types of materials. However,
if you do work with any of these materials, it is extremely
important to clean the tool using compressed air.
LUBRICATION
All of the bearings in this tool are lubricated with a sufficient
amount of high grade lubricant for the life of the unit under
normal operating conditions. Therefore, no further lubrica-
tion is required.
