Maintenance Hazards
•
Shut off power to all controls and ensure that all moving parts are secured from
inadvertent motion prior to performing any adjustments or repairs.
•
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.
•
DO NOT attempt to repair or tighten any hydraulic hoses or fittings while the
machine is powered on or when the hydraulic system is under pressure.
•
Always relieve hydraulic pressure from all hydraulic circuits before loosening or
removing hydraulic components.
•
DO NOT use your hand to check for leaks. Use a piece of cardboard or paper to
search for leaks. Wear gloves to help protect hands from spraying fluid.
•
Use only replacement parts or components that are approved by JLG. To be
considered approved, replacement parts or components must be 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.
•
Use only approved non-flammable cleaning solvents.
•
Do not replace items critical to stability, such as batteries or solid tires, with items of
different weight or specification. Do not modify the MEWP in any way to affect
stability.
•
Refer to the Service & Maintenance Manual for the weights of critical stability items.
Modification or alteration of a MEWP shall be made only with prior written
