SECTION 4. MACHINE OPERATION
4.1 DESCRIPTION
This machine is a self-propelled aerial work platform on top of
an elevating mast mechanism. The Lift’s intended purpose is to
position personnel with their tools and supplies at positions
above ground level. The machine can be used to reach work
areas located above machinery or equipment positioned at
ground level.
This JLG Lift has a primary operator Control Station in the plat-
form. From this Control Station, the operator can drive and steer
the machine in both forward and reverse directions, raise and
lower the platform. The machine is also equipped with a Ground
Control Station which will override the Platform Control Station.
Ground Controls operate lift up, down and emergency stop.
Ground Controls are to be used only in an emergency to lower
the platform to the ground should the operator in the platform
be unable to do so.
4.2 OPERATING CHARACTERISTICS AND LIMITATIONS
General
A thorough knowledge of the operating characteristics and lim-
itations of the machine is always the first requirement for any

ment.
Placards
Important points to remember during operation are provided at
the control stations by DANGER, WARNING, CAUTION, IMPOR-
TANT, NOTICE, and INSTRUCTION placards. This information is
placed at various locations for the express purpose of alerting
personnel of potential hazards constituted by the operating
characteristics and limitations of the machine. See foreword for
