GENERAL

This section provides information on the procedures to be fol-
lowed and on the systems and controls to be used in the event
an emergency situation is encountered during machine opera-
tion. Prior to operation of the machine and periodically thereaf-
ter, the entire operating manual, including this section, should
be reviewed by all personnel whose responsibilities include any
work or contact with the machine.

Emergency Stop Switch

These large red buttons, one located at the Ground Control Sta-
tion and one at the Platform Control Station, will immediately
stop the machine when depressed.

SECTION 4. EMERGENCY PROCEDURES
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 controlling the plat-
form lift up and down functions from the ground. Place the
power select switch in the ground position and operate the lift
switch to lift up or down.

Manual Descent

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 at the rear of the machine, above the left rear
wheel. The handle is connected, by a cable, to the manual
descent valve on the lift cylinder. Pulling the manual descent
handle opens the valve spool, lowering the platform.
