MAINTENANCE

WARNING:
When servicing, use only identical replacement parts.
Use of any other parts could 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 could result in serious personal
injury.
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
lubrication is required.

 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.
