CAUTION
Raising the machine for service
or maintenance relying solely on
mechanical or hydraulic jacks could be
dangerous. The mechanical or hydraulic
jacks may not be enough support or may

performed. Contact with moving parts or
hot surfaces may cause personal injury.
Keep fingers, hands, and clothing clear
of rotating components and hot surfaces.
