SECTION 5. MACHINE OPERATION
5.1 DESCRIPTION
This machine is a towable hydraulic personnel lift equipped with
a work platform on the end of an elevating and rotating boom.
The primary operator control station is in the platform. The oper-
ator can raise or lower the main or tower boom or swing the
boom to the left or right. Standard boom swing is 410° non-con-
tinuous left and right of the stowed position. The machine has a
Ground Control Station which will override the Platform Control
Station. Ground Controls operate Boom Lift and Swing, and 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.
5.2 BOOM OPERATING CHARACTERISTICS AND LIMITATIONS

out any load in platform, if:

2. Machine is not coupled to tow vehicle.
3. Load is within manufacturer’s rated capacity.
4. All machine systems are functioning properly.
5. Machine is as originally equipped from JLG.

FORWARD and BACKWARD stability. The machine’s position of
least FORWARD stability is shown in (See Figure 5-1.), and its posi-
tion of least BACKWARD stability is shown in (See Figure 5-2.)
