SECTION 4. MACHINE OPERATION
4.1 DESCRIPTION
This machine is a self-propelled hydraulic lift equipped with a
work platform on an elevating scissor mechanism.
The JLG Scissor 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, raise and lower the platform and, if equipped,
operate the powered deck extension and the outriggers. 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 emer-
gency to lower the platform to the ground should the opera-
tor in the platform be unable to do so.
4.2 ENGINE OPERATION
Platform/Ground Select Switch
The power selector switch functions to direct electrical power
to the desired control station. With the switch in the ground
position, power is supplied to the emergency stop switch at
the ground control station. When the switch is in the platform
position, power is supplied to the emergency stop switch at
the platform control station. The switch should be in the off
position when parking the machine overnight.
Emergency Stop Switch
This switch, when in the on position (pulled out), provides
electrical power to the ground controls or platform controls,
as applicable. In addition, the switch can be used to turn off
power (depressed) to the function controls in the event of an
emergency.
Speed Switch
There is a three position speed switch at the platform control
station. For high speed (Rabbit), Mid Speed (White Line) and
Low Speed (Turtle). All three speeds will work with the drive
function. The high speed select will not operate the lift function.
