SECTION 4. MACHINE OPERATION
4.1 MACHINE DESCRIPTION
The EL Series line of machines are a manually propelled
machine, with an aerial work platform mounted to an ele-
vating aluminum mast mechanism. The mast is raised and
lowered by a hydraulic cylinder extending between mast
section-1 and -2, the remaining mast sections are propor-
tionally extended and retracted using steel chains and
cables. Hydraulic pressure is supplied to the lift cylinder
by an electrically powered hydraulic pump. All EL Series
feature a steel base frame with aluminum outrigger beams
manually leveled and configured in an “X” pattern. The
platform may be raised only when lift is positioned on
smooth, firm surface on which the machine is capable of
being leveled. The personnel lift’s intended purpose is to
provide personnel (with their tools and supplies) access to
areas above ground level.
The JLG personnel lift has a primary operator control sta-
tion in the platform. From this control station the operator
can raise and lower the platform. A ground control station
is also provided. This station contains a keyed power on/
off switch, an emergency stop button and an emergency/
manual decent valve which enables the platform to be
lowered to the ground in an emergency, if the operator in
the platform is unable to do so, or if a power failure should
occur.
Instructions and warnings are posted adjacent to both
operator control stations and at other places on the
machine. It is extremely important that the user/operator
know what instructions and warnings are placed on the
machine and in the manual. And that these instructions
and warning’s be reviewed periodically. The JLG person-
nel lift is designed to provide efficient and safe operation
when maintained and operated in accordance with
instructions and warnings on the machine, in the Operat-
ing, Safety and Maintenance 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.It is absolutely
necessary that the JLG lift be regularly maintained in
accordance with this manual.
Any evidence of lack of maintenance, malfunction, exces-
sive wear, damage or modification to the machine must be
reported immediately to the machine owner, the jobsite
supervisor or safety manager and that the machine be
taken out of service until all discrepancies are corrected.
The JLG personnel lift is not intended to be used to lift
material other than supplies which personnel in the plat-
form require to do their job. Supplies or tools which
extend outside the platform are prohibited except for JLG
approved recepticals. The personnel lift must not be used
as a forklift, crane, or support for overhead structure.
The total platform rated capacity must be uniformly distrib-
uted in the center of the platform. This means that the total
combined weight of personnel, tools and supplies loaded
into the platform must not exceed the platform total rated
capacity.
4.2 GENERAL
This section provides the necessary information needed
to operate the machine. Included in this section are the
procedures for set-up, starting, stopping, raising, lower-
ing, platform loading and transporting. It is important that
the user read and understand the proper procedures
before operating the machine. Although some of the more
important operating safety precautions will be listed in the
following paragraph sections, it is extremely important all
safety precautions in Section 1 - Safety Precautions be
read and understood before operating machine. If a “Daily
Walk-Around Inspection”, (see Section 2-4.) has not been
completed, perform this inspection before starting set-up
and operation. The operator must also be familiar with all
machine controls as described in Section 3 - User/Opera-
tor Responsibilities and Machine Controls.
