SECTION 4. MACHINE OPERATION
4.1 DESCRIPTION
This machine is a self-propelled aerial work platform on top of
an elevating ‘scissor’ mechanism. The Scissor Lift’s intended pur-
pose 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 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. The machine has a Ground Control Station
which will override the Platform Control Station. Ground Con-
trols 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.
NOTE: All platform extension capacities are 250 lb (120 kg).
4.2 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 posi-
tion, power is supplied to the emergency stop switch at the
ground control station. When the switch is in the platform posi-
tion, 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 (out) position, provides electrical
power to the ground controls or platform controls, as applica-
ble. In addition, the switch can be used to turn off power (push
the switch IN) to the function controls in the event of an emer-
gency.
