OPERATING CHARACTERISTICS AND LIMITATIONS

Capacities

The boom can be raised above horizontal with or without any
load in platform, if:
1.
Machine is positioned on a smooth, firm surface within the
limits of the maximum operating slope.
2.
Load is within manufacturer's rated capacity.
3. All machine systems are functioning properly.
4. Machine is as originally equipped from JLG.

Platform Load Sensing System (LSS)

The Platform Load Sensing System provides the platform capac-
ity to the control system. The control system will light the applica-
ble capacity zone light in both the platform control box and the
ground control station based on the value observed by the LSS
system.
The control system determines which capacity zone (Unrestricted
550 lb (250 kg) or Restricted 750 lb (340kg) the platform can be
operated in. If the operator attempts to cross the boundary of the
current zone and enter the next zone of lessor or no restriction
with more weight in the platform than what is allowed, the
machine will stop at the boundary of the current zone and not
enter the zone of lessor or no restriction. At this point, the control
system will only allow the boom telescope function to retract and
will only allow the boom lift function to lift up.
When the LSS system senses a platform load equal to or less than
550 lb (250 kg), platform position is unrestricted within the enve-
lope boundaries.
If the LSS system senses an overload condition, boom functions
will be disabled, the overload alarm will sound at the platform.
