Chapter 8 – Operation
46 SB85J Fixed Axle – 0112975
If the platform becomes significantly overloaded, or if an
upward force on the platform exceeds approximately
2225 N (500 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 Figure 8.6 and 8.7).
Figure 8.7 – 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 func-
tions are operational.
A
Caution
The emergency power system is for emergency low-
ering 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 opera-
tion.
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 ei-
ther 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 ma-
chine is being driven with the booms in the stowed posi-
tion. This allows the machine to be driven without the
system sensing an overload due to rough ground condi-
tions.
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.
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 be-
fore operating the generator.
Do not operate the generator unless the hydraulic oil tem-
perature 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 switch
(refer to Figure 8.8) in the generator position.
Figure 8.8 – Upper Control Panel Front
The engine will run at high idle while the generator is
operating. The generator will continue to operate as long
as the engine is running and the switch is in the genera-
tor position.
Dual Fuel
The dual fuel switch is located on the front of the lower
control panel.
Before starting the engine, place the fuel switch in the
gasoline or the LPG position. Open the shut-off valve on
