SECTION 4. MACHINE OPERATION
4.1 MACHINE DESCRIPTION
The JLG VPSP model lifts are an electric self-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 or
cables. Hydraulic pressure is supplied to the lift cylinder
by an electrically powered hydraulic pump. All VP Series
models feature a steel base frame with swivel caster
wheels mounted on the front and fixed drive wheels on the
rear of the machine. The personnel lift’s intended purpose
is to provide personnel access to areas above ground
level.
The JLG VPSP lift has a primary controller in the platform.
From the platform control the operator can drive the unit
and raise or lower the platform. Ground controls are also
provided, these controls consist of a keyed power on/off/
grnd switch, an emergency stop button, an emergency/
manual decent valve and a platform up/down control
switch.
Instructions and warnings are posted adjacent to both
platform and ground 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 be reviewed periodically.
The JLG VP personnel lift is designed to provide efficient
and safe operation when maintained and operated in
accordance with instructions and warnings on the
machine, in the Operating, Safety and Maintenance Man-
ual, ANSI Responsibilities Manual and by obeying all job
site and government rules and regulations. As with any
type of machine, the operator is very important to efficient
and safe operation. It is absolutely necessary that the JLG
VP 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 its owner, the job site supervisor,
or safety manager and that the machine be taken out of
service until all discrepancies are corrected.
The JLG VPSP personnel lift is not intended to be used to
lift material other than hand-picked stock or supplies. Sup-
plies or tools which extend outside the platform are pro-
hibited except for JLG approved receptacles. The
personnel lift must not be used as a forklift, crane, or sup-
port for overhead structure.
The total platform capacity of the VPSP personnel lift must
be uniformly distributed in the platform. This means that
the total combined weight of personnel, tools and sup-
plies loaded into the platform must not exceed the plat-
form capacity figures.
4.2 GENERAL
This section provides the necessary information needed
to operate the machine. Included in this section are proce-
dures for driving the machine, raising, lowering and load-
ing the platform, and also transporting the machine. 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 performed, do so before starting set-up and opera-
tion. The operator must also be familiar with all lift controls
as described in Section 3 - "User/Operator Responsibili-
ties and Machine Controls".
