Chapter 8 – Operation

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 is equipped with a four wheel drive system.
This system operates full time and requires no action
by the operator.
High Range Speed Selector
The high range speed selector (refer to Figure 8.9) works
in conjunction with the drive range switch to determine
the maximum drive speed when the drive range selector
is in the HI position. LO drive range speed is not affected
by the high range speed selector.
For maximum drive speed 4.8 km/h (3.0 mph) with low
gradeability, pull the knob upward and rotate it 90 de-
grees to lock it in the up position.
For slower drive speed 2.4 km/h (1.5 mph) with higher
gradeability, push the knob downward and rotate it 90
degrees to lock it in the down position.

AC Generator
The optional generator supplies power to the electrical
outlet only when the engine is running and the machine
is stationary. The machine functions will not operate
when the machine/generator selector switch is in the
generator position.
Figure 8.8 – Lower Control Panel
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 functions
are operational.
A Caution
The emergency power system is for emergency
lowering and stowing only. The length of time the
pump can be operated depends on the capacity
of the battery. Do not use this system for normal
operation.
If the platform overload sensing system is tripped while
operating the machine or if the system is in error mode
and can not be reset, the emergency power system
may still be used for emergency machine operation from
either the lower or upper controls.
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
machine is being driven with the booms in the stowed
position. This allows the machine to be driven without
the system sensing an overload due to rough ground
conditions.
