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

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.
Electric tools used on fiberglass material, wallboard,
spackling compounds, or plaster are subject to acceler-
ated wear and possible premature failure because the
fiberglass chips and grindings are highly abrasive to bear-
ings, brushes, commutators, etc. Consequently, we do not
recommended using this product 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
product using compressed air.

All of the bearings in this product are lubricated with a suf-
ficient amount of high grade lubricant for the life of the unit

lubrication is required.
POWER SUPPLY CORD REPLACEMENT
