4.1
GENERAL
This machine is a Mobile Elevating Work Platform (MEWP) used to position personnel,
along with their necessary tools and materials at work locations.
The primary operator control station is in the platform. From this control station, the
operator can drive and steer the machine in both forward and reverse directions. The
operator can raise or lower the main or tower boom or swing the boom to the left or
right.
Standard boom swing is 360° continuous left and right of the stowed position. The
machine has a Ground Control Station which will override the Platform Control Station.
Ground Controls operate all functions except drive and steer. Except for performing
inspections and the Function Check, the ground controls are to be used in an
emergency to lower the platform to the ground should the operator in the platform be
unable to do so.

OPERATING CHARACTERISTICS AND LIMITATIONS
4.2.1
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.
4.2.2
Platform Load Sensing System (LSS)
The Platform Load Sensing System provides the platform load to the control system.
If the LSS system senses an overload condition, boom functions will be disabled, the
overload indicator is illuminated at both control stations, and the overload alarm will
sound. Reduce the weight in the platform to not exceed the rated workload indicated
on the capacity decal, then the controls will work again.
4.2.3
Stability
Machine stability is based on two positions which are called FORWARD and BACKWARD
stability. The machines position of least FORWARD stability is shown in
