A
Danger
The aerial platform can tip over if it becomes un-
stable. Death or serious injury will result from a tip-
over accident. Do not exceed the capacity values
indicated on the platform rating placard.
The overload sensing system is not active when the ma-
chine is being driven with the main boom below hori-
zontal and fully retracted. This allows the machine to be
driven without the system sensing an overload due to
rough ground conditions.
To eliminate repeated tripping of the system during ma-
chine operation, there is a five second delay in machine
functions following:
• starting the engine.
• placing the drive/boom selector switch in the boom
position when the main boom is below horizontal
and fully retracted.
• removing excess load from the platform.
Four Wheel Drive
The machine may be equipped with a four wheel drive
system. This system operates full time and requires no
action by the operator.
Four wheel drive machines have a “4x4” decal on each
side of the chassis and all four of the wheel hubs are
drive hubs and look the same.
AC Generator
The generator supplies power to the electrical outlet only
when the engine is running and the machine is station-
ary. The machine functions will not operate when the
machine/generator selector switch is in the generator
position.
A
Caution
Cold hydraulic oil does not flow well and may pro-
duce improper generator output voltage. Improper
outlet voltage can damage some electrical power
tools and equipment. Warm the hydraulic oil before
operating the generator.
Do not operate the generator unless the hydraulic oil
temperature is at least 38°C (100°F). Refer to Cold
Weather Start-Up for a hydraulic oil warm-up procedure.
Start the engine and place the machine/generator se-
lector switch (refer to Figure 8.7) in the generator posi-
tion.
Figure 8.5 – Upper Control Panel
If the platform becomes significantly overloaded, or if
an upward force on the platform exceeds approximately
445 N (100 lb), the system will enter into error mode,
stopping all functions from the upper and lower controls.
The horn will then sound constantly and the overload
light will stay illuminated at the upper and lower controls
(refer to Figures 8.5 and 8.6).
Figure 8.6 – Lower Controls
The system will remain in error mode until the excess
load is removed from the platform and the emergency
stop button or start switch is cycled off and back on,
resetting the system. At that time, the machine func-
tions are operational.
