SECTION 4. MACHINE OPERATION
4.1 DESCRIPTION
This machine is a self-propelled elevating ‘sizzor’ aerial
work platform. The Sizzor Lift’s intended purpose is to
position personnel with their tools and supplies at posi-
tions above ground level. The machine can be used to
reach work areas located above machinery or equipment.
The JLG Sizzor 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 as well as raise and lower the platform. The
machine has a Ground Control Station which will override
the Platform Control Station. Ground Controls operate Lift
Up and Lift Down and are to be used only for daily check
or in an emergency to lower the platform to the ground
should the operator in the platform be unable to do so.
Instructions and hazard warnings are posted adjacent to
both operator control stations and at other places on the
machine. It is extremely important that operators know
what instructions and warnings are placed on the
machine, and review these periodically so that they are
fresh in their minds. Vibrations emitted by these machines
are not hazardous to an operator in the work platform.
The JLG Sizzor Lift is designed to provide efficient and
safe operation when maintained and operated in accor-
dance with warnings on the machine, the Operating and
Safety Manual, the Service 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 Sizzor Lift be regularly maintained in accordance
with this manual and the machine Service and Mainte-
nance Manual, and that any evidence of lack of mainte-
n a n c e , m a l f u n c t i o n , e x c e s s i ve w e a r, d a m a g e o r
modification to the machine be reported immediately to
the machine owner or the jobsite supervisor or safety
manager and that the machine be taken out of service
until all discrepancies are corrected.
The JLG Sizzor Lift is not intended to be used to lift mate-
rial other than supplies which personnel in the platform
require to do their job. Supplies or tools which extend out-
side the platform are prohibited. It must not be used as a
forklift, crane, support for overhead structure, or to push
or pull another object.
The machine has a manual descent system which will
allow the platform to lowered without power from the
engine/motor powered pump.
The JLG Sizzor Lift is powered using hydraulic motors and
cylinders for the various machine motions. The hydraulic
components are controlled by electrically activated
hydraulic valves using switches and the joystick control-
ler. The machine is equipped with a Enable Switch which
must be pressed before activating the DRIVE, LIFT or
STEER functions. The Enable Switch has a built-in timer
which shut off power to these functions if they are not acti-
vated within 3 seconds after Enable Switch is depressed.
The speeds of functions controlled by the joystick control-
ler are variable from zero to maximum speed depending
upon the position of the controller. Functions controlled
by toggle switches are either on or off and higher or lower
speed is possible only when the applicable high function
speed control switch at the Platform Control Station is
used in conjunction with the function toggle switch. All
switches at the platform are guarded to prevent inadvert-
ent operation by individual switch guards.
The JLG Sizzor is a two or four wheel drive machine with
drive power being supplied by a hydraulic motor for each
drive wheel. Each drive wheel is supplied with a hydrauli-
cally released, spring applied brake. The brakes are auto-
matically applied anytime the Drive controller is returned
to the neutral position.
The total combined weight of personnel, tools and sup-
plies must not exceed the given capacity for a particular
model. Refer to Table 4-1, Operating Specifications.
The platform may be raised only when positioned on firm,
level and uniform surfaces. Leveling jacks, if provided, are
to assist in leveling the Sizzor Lift. The Sizzor Lift must be
level when operating on leveling jacks.
