DURING MAINTENANCE
Personnel
• Only authorized personnel can service and repair
the machine.
Attachments
• Place attachments that have
been removed from the machine
in a safe place and manner to
prevent them from falling.
Working Under The Machine
• Always lower all movable work
equipment to the ground or to
their
lowest
position
performing service or repairs
under the machine.
• Always block the tires of the machine securely.
• Never work under the machine if the machine is
poorly supported.
Keeping The Machine Clean
If equipped, DO NOT aim high pressure spray
equipment at or near the Retractable Ladder Sys-
tem (RLS) power pack, actuator box, bearings or
electrical harnesses. Moisture introduced in the
electrical harnesses may result in uncontrolled
ladder movement.
• Spilled
oil,
grease,
scattered tools, etc. can
cause you to slip or trip.
Always
keep
your
machine clean and tidy.
• If water gets into the
electrical system, there is
danger that the machine may move unexpectedly
and/or damage to components may occur. DO
NOT use water or steam to clean any sensors,
connectors, or the inside of the operator's
compartment.
before
• Use extreme care when washing the electrical
control cabinet. DO NOT allow water to enter the
control cabinet around the doors or vents. DO
NOT allow any water to enter the cooling air inlet
duct above the electrical control cabinet. If water
enters the control cabinet (through any opening
or crevice) major damage to the electrical
components may occur.
• Never spray water into the rear wheel electric
motor covers. Damage to the wheel motor
armatures may occur.
• DO NOT spray water into the retarding grids.
Excess water in the retarding grids can cause a
ground fault, which will prevent propulsion.
Use Of Lighting
• When checking fuel, oil, coolant, or battery
electrolyte,
always
explosion specifications. If lighting without this
protection is used, there is a danger of explosion.
Precautions With The Battery
• Before
repairing
electrical system or when
performing welding, turn
the key switch to the OFF
position. Wait two minutes
after
the
engine
has
stopped,
and
if
warning lights illuminate,
then turn the master disconnect switch (3, Figure
20-2) and starter disconnect switch (4) located in
the isolation box (6) to the OFF position. When
the switches are in the OFF position, LED lights
(8) will be illuminated.
