LOCATIONS
Emergency Stop Switch

Ground Control Station
The Ground Control Station is located on the left side of
the machine frame. The controls on this panel provide the
means for overriding the platform controls and for control-
ling the platform lift up and down and ignition functions
from the ground. Position the Ignition/Emergency Stop
switch to ON, position the PLATFORM/ GROUND SELECT
switch to the GROUND position and operate the appropri-
ate switch, LIFT or IGNITION.
IF MACHINE IS EQUIPPED WITH PLATFORM EXTENSION OR TRA-
VERSING DECK, RETRACT DECK BEFORE LOWERING PLAT-
FORM.
Manual Descent - (Engine/Pump Failure -
Platform Controls)
In the event of engine/pump failure while operating the
machine from the platform console, the following proce-
dure should be followed to lower the platform. Turn the
POWER ON switch to ON. Place and hold the lift control
switch to down. When platform is completely down, return
lift control switch to center off and position power on
switch to off.
Manual Descent - (Engine/Pump Failure -
Ground Controls)
The following procedure should be used to lower the plat-
form from the ground controls in the event of engine/
pump failure.Turn MAIN POWER switch to ON and PLAT-
FORM/GROUND SELECT switch to GROUND. For battery
powered machines, position MAIN POWER switch to
GROUND. Place LIFT control switch to DOWN. When plat-
form is completely down, return LIFT control switch to
center OFF and position MAIN POWER switch to OFF.
Manual Descent - (Complete Loss of Power)
The manual descent valve is used, in the event of total
power failure, to lower the platform using gravity. The
manual descent handle is located on the center rear of the
machine frame, just above the first set of scissor arms.
The handle is connected, by a cable, to the manual
descent valve on the lift cylinder. Pulling the manual
descent handle opens the valve, lowering the platform.
