SUPPORT MACHINE PROPERLY
Always lower the attachment or implement to the ground
before you work on the machine. If you must work on a
lifted machine or attachment, securely support the
machine or attachment.
Do not support the machine on cinder blocks, hollow tiles,
or props that may crumble under continuous load. Do not
work under a machine that is supported solely by a jack.
Follow recommended procedures in this manual.

SERVICE COOLING SYSTEM SAFELY
Explosive release of fluids from pressurized cooling
system can cause serious burns.
Shut off engine. Only remove filler cap when cool enough
to touch with bare hands. Slowly loosen cap to first stop
to relieve pressure before removing completely.
