MAINTENANCE

When servicing, use only identical replacement parts.
Use of any other part 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.
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.
Do not attempt to modify this tool or create accessories
not recommended for use with this tool. Any such
alteration or modifi 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,
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 the 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.
