Maintenance Hazards
• Shut off power to all controls and ensure that all oper-
ating systems are secured from inadvertent motion

• Never work under an elevated platform until it has been
fully lowered to the full down position, if possible, or
otherwise supported and restrained from movement
with appropriate safety props, blocking, or overhead
supports.
• Always relieve hydraulic pressure from all hydraulic cir-
cuits before loosening or removing hydraulic compo-
nents.
• Always disconnect batteries when servicing electrical
components or when performing welding on the
machine.
• Shut down the engine (if equipped) while fuel tanks are
being filled.
• Ensure replacement parts or components are identical
or equivalent to original parts or components.
• Never attempt to move heavy parts without the aid of a
mechanical device. Do not allow heavy objects to rest
in an unstable position. Ensure adequate support is
provided when raising components of the machine.
