NOTICE: If you use a spare battery to continue
the operation, rest the tool at least 15 min.

MAINTENANCE
CAUTION: Always be sure that the tool is
switched off and the battery cartridge is removed
before attempting to perform inspection or
maintenance.
NOTICE: Never use gasoline, benzine, thinner,
alcohol or the like. Discoloration, deformation or
