SECTION 1 - SAFETY PRECAUTIONS
Maintenance Hazards
• Shut off power to all controls and ensure that all operating
systems 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.
• Always relieve hydraulic pressure from all hydraulic circuits before loosening or removing hydraulic components.
• 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.
• Remove all rings, watches, and jewelry when performing
any maintenance. Do not wear loose fitting clothing or
long hair unrestrained which may become caught or
entangled in equipment.
• Use only clean approved non-flammable cleaing solvents.
• Never alter, remove, or substitute any items such as counterweights, tires, batteries, platforms or other items that
may reduce or affect the overall weight or stability of the
machine.
• Reference the Service and Maintenance Manual for the
weights of critical stability items.
