1-2 – JLG Lift – 3120825


• Platform-to-structure transfers at elevated positions arediscouraged. Where transfer is necessary, enter/exitthrough the gate only with the platform within 1 foot(0.3m) of a safe and secure structure. 100% tie-off isalso required in this situation using two lanyards. Onelanyard must be attached to the platform with the sec-ond lanyard attached to the structure. The lanyard con-nected to the platform must not be disconnected untilthe transfer to the structure is safe and complete.

Electrocution Hazards• This machine is not insulated and does not provide

protection from contact or proximity to electrical cur-rent.

• Maintain safe distance from electrical lines, apparatus,or any energized (exposed or insulated) parts accord-ing to the Minimum Safe Approach Distance (MSAD)as shown in Table 1-1.

• Allow for machine movement and electrical line sway-ing.

DO NOT MANEUVER MACHINE OR PERSONNEL INSIDE PROHIB-ITED ZONE (MSAD). ASSUME ALL ELECTRICAL PARTS AND WIR-ING ARE ENERGIZED UNLESS KNOWN OTHERWISE.

Tipping Hazards• The user should be familiar with the surface before

driving. Do not exceed the allowable sideslope andgrade while driving..

• Do not elevate platform or drive with platform elevatedwhile on a sloping, uneven, or soft surface.

• Before driving on floors, bridges, trucks, and other sur-faces, check allowable capacity of the surfaces.

• Never exceed the maximum platform capacity. Distrib-ute loads evenly on platform floor.

SECTION 2. PREPARATION AND INSPECTION

2.1 GENERAL

This section provides the necessary information neededby those personnel that are responsible to place themachine in operation readiness, and lists checks that areperformed prior to use of the machine. It is important thatthe information contained in this section be read andunderstood before any attempt is made to operate themachine. Ensure that all the necessary inspections havebeen completed successfully before placing the machineinto service. These procedures will aid in obtaining maxi-mum service life and safe operation.

SINCE THE MACHINE MANUFACTURER HAS NO DIRECT CON-TROL OVER THE FIELD INSPECTION AND MAINTENANCE,SAFETY IS THE RESPONSIBILITY OF THE OWNER/OPERATOR.

2.2 PREPARATION FOR USE

Before a new machine is put into operation it must becarefully inspected for any evidence of damage resultingfrom shipment and inspected periodically thereafter, asoutlined in paragraph 2-3, Delivery and Periodic Inspec-tion. The unit should be thoroughly checked for hydraulicleaks during initial start-up and run. A check of all compo-nents should be made to assure their security.

All preparations necessary to place the machine in opera-tion readiness status are the responsibility of manage-ment personnel.

SECTION 4. MACHINE OPERATION

4.1 DESCRIPTION

This machine is a self-propelled elevating ‘sizzor’ aerialwork platform. The Sizzor Lift’s intended purpose is toposition personnel with their tools and supplies at posi-tions above ground level. The machine can be used toreach work areas located above machinery or equipment.

The JLG Sizzor Lift has a primary operator Control Stationin the platform. From this Control Station, the operator candrive and steer the machine in both forward and reversedirections as well as raise and lower the platform. Themachine has a Ground Control Station which will overridethe Platform Control Station. Ground Controls operate LiftUp and Lift Down and are to be used only for daily checkor in an emergency to lower the platform to the groundshould the operator in the platform be unable to do so.

Instructions and hazard warnings are posted adjacent toboth operator control stations and at other places on themachine. It is extremely important that operators knowwhat instructions and warnings are placed on themachine, and review these periodically so that they arefresh in their minds. Vibrations emitted by these machinesare not hazardous to an operator in the work platform.

The JLG Sizzor Lift is designed to provide efficient andsafe operation when maintained and operated in accor-dance with warnings on the machine, the Operating andSafety Manual, the Service and Maintenance Manual andall jobsite and government rules and regulations. As withany type of machinery, the operator is very important toefficient and safe operation. It is absolutely necessary thatthe JLG Sizzor Lift be regularly maintained in accordancewith this manual and the machine Service and Mainte-nance Manual, and that any evidence of lack of mainte-nance, mal funct ion, excessive wear, damage ormodification to the machine be reported immediately tothe machine owner or the jobsite supervisor or safetymanager and that the machine be taken out of serviceuntil 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 platformrequire to do their job. Supplies or tools which extend out-side the platform are prohibited. It must not be used as aforklift, crane, support for overhead structure, or to pushor pull another object.

The machine has a manual descent system which willallow the platform to lowered without power from theengine/motor powered pump.

The JLG Sizzor Lift is powered using hydraulic motors andcylinders for the various machine motions. The hydrauliccomponents are controlled by electrically activatedhydraulic valves using switches and the joystick control-

ler. The machine is equipped with a Enable Switch whichmust be pressed before activating the DRIVE, LIFT orSTEER functions. The Enable Switch has a built-in timerwhich 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 dependingupon the position of the controller. Functions controlledby toggle switches are either on or off and higher or lowerspeed is possible only when the applicable high functionspeed control switch at the Platform Control Station isused in conjunction with the function toggle switch. Allswitches 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 withdrive power being supplied by a hydraulic motor for eachdrive 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 returnedto the neutral position.

The total combined weight of personnel, tools and sup-plies must not exceed the given capacity for a particularmodel. 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, areto assist in leveling the Sizzor Lift. The Sizzor Lift must belevel when operating on leveling jacks.

4.2 GENERALThis section provides the necessary information neededto operate the machine. Included in this section are theprocedures for starting, stopping, traveling, steering, park-ing, platform loading and transporting.
