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 sawdust
which may impede the operation of the
lower guarding system. A dirty guarding
system may limit the proper operation which
could result in serious personal injury. The most
effective way to accomplish this cleaning is with
compressed air. If the dust is being blown out
of the guards be sure the proper eye and
breathing protection is used.
• Never use gasoline, benzine, thinner, alcohol
or the like. Discoloration, deformation or cracks
may result.
