MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspec-
tion or maintenance.
Clean out the upper and lower guards to
•
ensure there is no accumulated metal chips
which may impede the operation of the
lower guarding system. A dirty guarding sys-
tem may limit the proper operation which could
result in serious personal injury. When using
compressed air to blow metal chips out of
the guards, wear a proper eye and breathing
protection.
• Never use gasoline, benzine, thinner, alcohol
or the like. Discoloration, deformation or cracks
may result.
Inspecting saw blade
• Check the blade carefully for cracks or damage
before and after each use. Replace a cracked or
damaged blade immediately.
• Continuing to use a dull blade may cause a dan-
gerous kickback and/or motor overload. Replace
with a new blade as soon as it no longer cuts
effectively.
