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 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 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 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.
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 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 (out) position, provides electrical power to the ground
controls or platform controls, as applicable. In addition, the switch can be used to
turn off power (push the switch IN) to the function controls in the event of an
emergency.
4.3 RAISING AND LOWERING
