GENERAL
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to various types of commercial
solvents and may be damaged by their use. Use clean cloths
to remove dirt, carbon dust, etc.
When electric tools are used on fiberglass boats, sports cars,
wallboard, spackling compounds, or plaster, it has been
found that they are subject to accelerated wear and possible
premature failure, as the fiberglass chips and grindings are
highly abrasive to bearings, brushes, commutator, etc.
Consequently it is not recommended that this tool be used
for extended work on any fiberglass material, wallboard,
spackling compounds, 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 OPERATION OR WHEN
BLOWING DUST. IF OPERATION IS DUSTY ALSO
WEAR A DUST MASK.
WARNING: DO NOT AT ANY TIME LET BRAKE
