SECTION 4. MACHINE OPERATION
4.1 MACHINE DESCRIPTION
ELI machines are manually propelled machines, with a
platform mounted to an elevating aluminum mast mecha-
nism. The mast is raised and lowered by a hydraulic cylin-
der extending between mast section-1 and -2, the
remaining mast sections are proportionally extended and
retracted using steel chains and cables. Hydraulic pres-
sure is supplied to the lift cylinder by an electrically pow-
ered hydraulic pump. The platform may be raised only
when lift is positioned on smooth, firm, level surface with
the floor brake set. The ELI personnel lift’s intended pur-
pose is to provide personnel (with their tools and supplies)
access to areas above ground level.
The ELI 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 the machine must 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 capacity is to be uniformly distributed in
the center of the platform. This means that the total com-
bined weight of personnel, tools and supplies loaded into
the platform must not exceed the total platform 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, raising, lowering, 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 Inspec-
tion”, (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/Operator Responsibilities
and Machine Controls.
