Maintenance Hazards
• Shut off power to all controls and ensure that all operating
systems are secured from inadvertent motion prior to per-
forming any adjustments or repairs.
• Never work under an elevated platform until it has been
fully lowered to the full down position, if possible, or other-
wise 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.

mechanical device. Do not allow heavy objects to rest in
an unstable position. Ensure adequate support is pro-
vided when raising components of the machine.

long hair unrestrained which may become caught or
entangled in equipment.

terweights, tires, batteries, platforms or other items that
may reduce or affect the overall weight or stability of the
machine.
