4.1DESCRIPTION.
This JLG Lift is EE Rated and Certif ied By Underwriter s
Laboratories.
This machine is a self-propelled hydraulic lift equipped
with a work platform on the end of an elevating, articulating and rotating boom. The JLG Lift’s intended purpose is
to position personn el wit h the ir tools an d supp lie s at po sitions above ground level, and can be used to reach work
areas located above machinery or equipment.
The JLG Lift has a primary operator Control Station 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 l ower the upper or lower
boom or swing the boom to the left or r ight. Standard
boom swing is 360 degree non-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 Upper and Lower 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. Ground Control also to be used in
Pre-Operation check.
Instructions and hazard alerts are posted on the operator
control stations and at other places on the machine. It is
extremely important that operators know what instructions
and hazard alerts are placed on the machine, and review
these periodically so that they are fresh in their minds.
Vibrations emitted by these machine s are not hazardous
to an operator in the work platform.
The JLG Lift is designed to provide efficient and safe operation when maintained and operated in accordance with
warnings on the machine, in the Operators & Safety Manual, and all jobsite and government rules and regulations.
As with any type of machinery, the operator is very important to efficient and safe operation. Owner/user/operator
must be familiar with Sections 6, 7, 8, 9, and 10 of ANSI
A92.5-1992. These sections contain the respon sibilities of
the owner, users, operators, lessors and lessees concerning safety, training, inspection, maintenance, application
and operation. It is absolutely necessary that the JLG L ift
be regularly maintained in accordance wit h this section
and the Servi ce an d Spec ificat ions se ction, and tha t any
evidence of lack of maintenance, malfunction, excessive
wear, damage or modification to the machin e be repor ted
immediately to the machine owner o r the job site su pervisor or safety manager and that the machin e be taken ou t
of service until all discrepancies are corrected.
Property of American Airlines
The JLG Lift is not intended to be used to lift material other
than supplies which personnel in the platform require to
do their job. Supplies or tools which extend outside the
platform are prohibited. It must not be used as a forklift,
crane, support f or overhea d structur e, or to push or pull
another object.
The JLG Lift is powered using a hydraulic pump and cylinders for various functions. The hydraulic components are
controlled by electrically activated hydraulic valves using
switches and control lev ers. The sp eeds of boo m functions are variable from zero to maximum speed depending upon the position of the function speed con trol.
Functions controlled by toggle switches are either on or
off. A foot operat ed switch in the platf orm must be
depressed before any controls will function and provides
a means of emergency stop when the operators foot is
removed from the footswitch.
The JLG Lift is a two wheel drive machine with drive power
being supplied by an electric motor at each drive wheel.
Each drive wheel is supplied with an electrically released,
spring applied brake. These brakes are automatically
applied any time the Drive switch is returned to neutral
position.
The unrestricted capacity of the JLG Lift is 500 LBS. (227
kg). This means that with a platform load of 500 LB. (227
kg) or less, the platform may be positioned anywhere the
boom will reach, with the machine on a smooth, firm, and
level surface.
