1.5 MAINTENANCE
General
This section contains general safety precautions which
must be observed during maintenance of this machine.
Additional precautions to be observed during machine
maintenance are inserted at the appropriate points in this
manual and in the Service and Maintenance Manual. It is
of utmost importance that maintenance personnel pay
strict attention to these precautions to avoid possible
injury to personnel or damage to the machine or property.
A maintenance program must be established by a quali-
fied person and must be followed to ensure that the
machine is safe.
Maintenance Hazards
• Shut off power to all controls and ensure that all oper-
ating 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 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.
• Remove all rings, watches, and jewelry when perform-
ing any maintenance. Do not wear loose fitting cloth-
ing or long hair unrestrained which may become
caught or entangled in equipment.
• Use only clean approved non-flammable cleaning sol-
vents.
• 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.
MODIFICATION OR ALTERATION OF AN AERIAL WORK PLAT-
FORM SHALL BE MADE ONLY WITH PRIOR WRITTEN PERMIS-
SION FROM THE MANUFACTURER
Battery Hazards
• Always disconnect batteries when servicing electrical
components or when performing welding on the
machine.
• Do not allow smoking, open flame, or sparks near bat-
tery during charging or servicing.
• Do not contact tools or other metal objects across the
battery terminals.
• Always wear hand, eye, and face protection when ser-
vicing batteries. Ensure that battery acid does not
come in contact with skin or clothing.
BATTERY FLUID IS HIGHLY CORROSIVE. AVOID CONTACT WITH
SKIN AND CLOTHING AT ALL TIMES. IMMEDIATELY RINSE ANY
CONTACTED AREA WITH CLEAN WATER AND SEEK MEDICAL
ATTENTION.
• Charge batteries only in a well ventilated area.
• Avoid overfilling the battery fluid level. Add distilled
water to batteries only after the batteries are fully
charged.
