4.2 OPERATING CHARACTERISTICS AND
LIMITATIONS
General
A thorough knowledge of the operating characteristics
and limitations of the machine is always the first require-
ment for any operator, regardless of the user’s experience
with similar types of equipment.
Placards
Important points to remember during operation are pro-
vided at the control stations by DANGER, WARNING,
CAUTION, IMPORTANT and INSTRUCTION placards. This
information is placed at various locations for the express
purpose of alerting personnel of potential hazards consti-
tuted by the operating characteristics and load limitations
of the machine. See FOREWORD for definitions of the
above placards.
Capacities
Raising the boom above horizontal and/or the extension
of the boom beyond the retracted position with or without
any load in the platform, is based on the following criteria:
1. Machine is positioned on a smooth, firm and level
surface.
2. Load is within manufacturer’s rated design capacity.
3. All machine systems are functioning properly.
4. Machine is as originally equipped from JLG.
Stability
This machine as originally manufactured by JLG Indus-
tries Inc., when operated within its rated capacity on a
smooth, firm and level supporting surface, and in accor-
dance with the instructions provided on the machine and
this manual, provides a stable machine for all platform
positions.
Machine stability is based on two positions which are
called FORWARD STABILITY and BACKWARD STABILITY.
The machines position of least forward stability is shown
in Figure 4-1. and its position of least backward stability is
shown in Figure 4-2.
