4.1 DESCRIPTION
This machine is a self-propelled aerial work platform on
top of an elevating ‘scissor’ mechanism. The Scissor Lift’s intended purpose is to position personnel with their tools and supplies at positions above ground level. The machine can be used to reach work areas located above machinery or equipment positioned at ground level.
The JLG Scissor Lift has a primary operator Control Sta­tion in the platform. From this Co ntrol Station, the operator can drive and steer the machine in both forward and reverse directions, raise and lower the platform and, if equipped, operate the powered deck e xtension. The machine has a Ground Control Station which will override the Platform Control Station. Ground Controls operate lift up and down. Ground Controls are to be used only in an emergency to lower the platform to the ground should the operator in the platform be unable to do so.
Instructions and haza rd warnings are pos ted adjacent to both operator control stat ions and at other place s on the machine. It is extremely important that operators know what instructions and warnings are placed on the machine, and review these periodical ly so that they are fresh in their minds.
The JLG Scissor Lift is designed to provide efficient and safe operation when maintained and operated in accor­dance with war nings on the mach ine, the Opera ting a nd Safety Manual, the Service and Maintenance Manual and all jobsite and government rules and regu lations. As with any type of machinery, the operator is very important to efficient and safe operation. It is absolutely necessary that the JLG Lift be regularly maintained in accordance with this manual and the machine Service and Maintenance Manual, and that any evidence of lack of maintenance, malfunction, excessive wear, damage or modification to the machine be reported immediately to the machine owner or the jo bsi te sup ervis or or safe ty man ag er and that the machine be taken out of service until all discrepancies are corrected.
The JLG Scissor Lift is not intended to be used to lift mate­rial other than supplies which pe rsonnel 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 Scissor 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 contr ol levers. The speeds of functions controlled by control levers are variable from zero to maximum speed, depending upon the position of the control lever. Functions controlled by
toggle or push-button switches a re either on or off. In some instanc es, a func tio n sw itch can b e u sed i n conj unc­tion with the controller to give the machine a higher func­tion speed range.
The JLG Scissor Lift is a two wheel drive machine with drive power being supplied to the rear wheels by a pump­driven drive axle. The rear wheels are supplied with a hydraulic disc brake. This brake is automatically applied any time the Drive controller is returned to the neutral position.
The platform capacity of the scissor lift is 454 kg (1,000 lb.). The weight in the plat form sh ould b e un iform ly di str ib­uted in the cent er of the p latform. T he total combined weight of personnel, tools and supplies must not exceed the above figures.
The platform may be raised only when positioned on firm, level and uniform surfaces.
