,_, WARNING: To ensure safety and reliability, all repairs - with the exception of
the externally accessible brushes -should be performed by a qualified service
technician at a Sears Service Center.
,_ WARNING: For your safety, ALWAYS turn off the switch and unplug the miter
saw from the power source before performing any maintenance or cleaning.
Electric tools are subject to accelerated wear and possible premature failure
when they are used to work on fiber glass boats and sports cars, wallboard,
spackling compounds, or plaster. The chips and grindings from these materials
are highly abrasive to electrical tool parts, such as bearings, brushes,
commutators, etc. Consequently, it is not recommended that this tool be used
for extended work on any fiberglass material, wallboard, spackling compound
or plaster. During any use on these materials, it is extremely important that the
tool is cleaned frequently by blowing with an air jet.
,_, WARNING: Always wear safety goggles or safety glasses with side shields
during power tool operations, or when blowing dust. If the operation is dusty,
also wear a dust mask.
ROUTINE MAINTENANCE
_. WARNING: DO NOT at any time allow brake fluids, gasoline, petroleum-
based products, penetrating oils, etc. to come in contact with plastic parts.
Chemicals can damage, weaken, or destroy plastic, which may result in serious
personal injury.
