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 drive or position the aerial plat-
form for elevated use near any drop-off, hole, slope,
soft or uneven ground, or other tip-over hazard.
Retract and lower the main boom and then drive to a
level surface when the tilt alarm sounds.
The tilt alarm is for added protection and does not jus-
tify operating on anything other than firm, flat, level sur-
faces.
Platform Overload Sensing System
All functions are stopped from the upper and lower con-
trols, when the platform overload limit is exceeded. The
horn will sound intermittently and the red overload light
(refer to Figure 4.8) will blink until the excess load is
removed from the platform. At that time, the machine
functions are again operational.
Note
If the platform overload sensing system is tripped while
operating the machine, the emergency power system
may still be used for emergency machine operation from
either the lower or upper controls.
Figure 4.8 – Upper Controls
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 Figure 4.8 and 4.9).
Figure 4.9 – 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
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.
