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, Lift Down, and Platform Traversing, (If Equipped). Thecontrols are to be used only for daily check or in an emer-gency to lower the platform to the ground should theoperator 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.

The JLG Sizzor Lift is designed to provide efficient andsafe operation when maintained and operated in accor-dance with warnings on the machine, the Operators &Safety, Service and Maintenance Manual and all jobsiteand government rules and regulations. As with any type ofmachinery, the operator is very important to efficient andsafe operation. Owner/user/operator must be familiar withSections 6, 7, 8, 9, and 10 of ANSI A92.6-1990. These sec-tions contain the responsibilities of the owner, users, oper-ators, lessors and lessees concerning safety, training,inspection, maintenance, application and operation. It isabsolutely necessary that the JLG Lift be regularly main-tained in accordance with this section, and that any evi-dence of lack of maintenance, malfunction, excessivewear, damage or modification to the machine be reportedimmediately to the machine owner or the jobsite supervi-sor or safety manager and that the machine be taken outof 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 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 controller.The machine is equipped with an Enable Switch whichmust be pressed before activating the DRIVE, LIFT orSTEER functions. The Enable Switch has a built-in timerwhich shuts off power to these functions if they are notactivated within 3 seconds after Enable Switch isdepressed. The speeds of functions controlled by the joy-stick controller are variable from zero to maximum speeddepending upon the position of the controller. Functionscontrolled by toggle switches are either on or off. Higheror lower speed is possible only when the applicable highfunction speed control switch at the Platform Control Sta-tion is used in conjunction with the drive function. Allswitches at the platform are guarded to prevent inadvert-ant 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 capacities of model 400RTS and 500RTS are foundon the capacity decals located on the machine. Thesecapacities are based on a load uniformly distributed in thecenter of the platform. This means that the total combinedweight of personnel, tools and supplies must not exceedthe given capacity for a particular model.

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.
