SECTION 1 - SAFETY PRECAUTIONS

SECTION 1. SAFETY PRECAUTIONS

1.1 GENERAL

This section prescribes the proper and sa fe practices for
major areas of machine usage which have been divided
into three basic categories: Driving, Operation, and Main­tenance. In order to promote proper usage of the
machine, it is mandatory that a daily routine be estab­lished based on the instructions given in this manual. A
maintenance program, using the in format ion prov ided in
the Service and Maintenance Man ual, must also be estab­lished by a qualified person and must be followed to
ensure that the machine is safe to operate.

The owner/user/operator/lessor/lessee of the machine
should not accept operating responsibility until this man­ual has been read and operation of the machine, under
the supervision of an experienced and qualified operator,
has been completed. Owner/user/operator/lessor/lessee
must be familiar with Sections 6, 7, 8, 9, and 10 of ANSI
A92.6 -1999. These sections contain the responsibilities of
the owner, users, operators, lessors and lessees concern­ing safety, training, insp ectio n, ma intena nce, a pplic ation
and operation. If there is a question on application and or
operation, JLG Industr ies should be consulted

MODIFICATION OR ALTERATION OF AN AERIAL PLATFORM
SHALL BE MADE ONLY WITH PRIOR WRITTEN PERMISSION OF
THE MANUFACTURER.

1.2 DRIVING/TOWING/CARRYING

Before driving the machine the user must be familiar with
the drive, steer and stopping characteristics. This is espe­cially important when driving in close quarters.

The user should be familiar with the driving surface before
driving. The surface s hould be firm and level an d grades
should not exceed the allowable grade for the machine,
25%.

NOTE: Remember that the key to safe and proper usage is

common sense and its careful application.

It is not recommended that this machine be towed, except
in the event of a machine malfunction, a total machine
power failure, or for loading on a truck. Refer to Section 6
for emergency towing procedures.

FAILURE TO COMPLY WITH SAFETY PRECAUTIONS LISTED IN
THIS SECTION AND ON MACHINE MAY RESULT IN MACHINE
DAMAGE, PERSONNEL INJURY OR DEATH AND IS A SAFETY
VIOLATION.

SECTION 4. MACHINE OPERATION

4.1 DESCRIPTION

This machine is a self-propelled hydraulic lift equipped
with a work platform on the tip of an e levating ‘sizzo r’
mechanism. The Sizzor Lift’s intended purpose is to posi­tion personnel with their tools and supplies at positions
above ground level, and can be used to reach work areas
located above machinery or equipment positioned at
ground level.

The JLG Sizzor has a primary operator Cont rol Station in
the platform. From t his Contro l Sta tion, the opera tor c an
drive and steer the machine in both fo rward an d reverse
directions. The machine has a Ground Control Station
which will override the Platform Control Station. Ground
Controls operate lift up and do wn and are to be us ed in an
emergency to lower the platform to the ground should the
operator in th e pl at fo rm be un abl e t o do so . Gr oun d Co n­trol is also to be us e d in Pre-Operation check.

Instructions and hazard alerts are posted on to both oper­ator control stations and at other places on the machi ne. 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 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 accor­dance with warnings on the machine, the Operators &
Safety, Service and Specification Manual and all jobsite
and government rules and regulations. As with any typ e o f
machinery, the operator is very import ant to effi cient and
safe operation. Owner/user/operator must be familiar with
Sections 6, 7, 8, 9, and 10 of ANSI A92.6-1999. 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 Lift be regularly main­tained in accordance with the seperate Service and Main­tenance Manual, and that any evidence of lack of
maintenance, ma lfunction, ex cessive wea r, damage or
modification to the machine be reported immediately to
the machine owne r or the jobs ite supervisor or safety
manager and that the machine be taken out of service
until all discrepancies are corrected.

nents are controlled by electric ally activated hydraul ic
valves using switches and control levers. The speeds of
functions controlled by control levers are variable from
zero to maximum speed depending upon the posi tion of
the function speed control. Functions controlled by toggle
switches are either on or off.

The JLG Sizzor is a two whee l drive machine wit h drive
power being supplied by an electric motor at each drive
wheel. Each drive wh eel is supp lied with an electrica lly
released, spring applied brake. These brakes are auto­matically applied any time the Drive switch is returned to
neutral position.

The capacity of the model 3369 electric is 1000 lb (455kg)
and the capacity of the mod el 3969 electric is 75 0 lb
(340kg),uniformly distributed in the center of the platform.
This means that t he to tal combine d weig ht of p ersonne l,
tools and supplies must not exceed the above figures.

4.2 GENERAL

This section provides the necessary information needed
to operate the machine. Included in this sectio n are proce­dures for traveling, steering, parking, platfor m loadi ng and
transporting. It is important that the user read and under­stand the proper procedures before operating the
machine.

4.3 MOTOR OPERATION

Platform/Ground Select Switch

The Platform/Ground Select switch functions to direct bat­tery power to the desired control station. With the switch
held in the ground position battery power is supplied to
the ground control station. When the switch is in the plat­form position, battery power is suppl ied to the platfor m
control station. When the switch is i n the center (off) posi ­tion, power is cut off from all functions. The switch should
be in center (off) position when recharging the batteries or
parking the machine overnight.

The JLG Sizzor Lift is not intended to be used to lift mate­rial other than supplies which personnel in t he 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 for overhead structure, or to push
or pull another object.

The JLG Sizzor Li ft is power ed using a hydraulic pump
and cylinders for various functions. The hydraulic compo-
