MAINTENANCE
WARNING
When servicing, use only identical replacement parts.
Use of any other parts may create a hazard or cause
product damage.
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 fl uids, gasoline, petroleum-
based products, penetrating oils, etc., come in contact
with plastic parts. They contain chemicals that can
damage, weaken or destroy plastic.
Do not abuse power tools. Abusive practices can damage
tool as well as workpiece.
WARNING
Do not attempt to modify this tool or create accessories
not recommended for use with this tool. Any such
alteration or modi
fi cation is misuse and could result
in a hazardous condition leading to possible serious
personal injury.
Electric tools used on fi berglass material, wallboard,
spackling compounds, or plaster are subject to
accelerated wear and possible premature failure because
the
fi berglass chips and grindings are highly abrasive to
bearings, brushes, commutators, etc.
Consequently, we do not recommend 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
suf
fi cient amount of high grade lubricant for the life of
the unit under normal operating conditions. Therefore, no
further lubrication is required.
POWER SUPPLY CORD REPLACEMENT
If replacement of the power supply cord is necessary, this
must be done by an authorized service center in order to
avoid a safety hazard.
