Section 5. Emergency Procedures; General; Emergency Operation - JLG 1930ES Operation & Safety Manual

5.1 GENERAL

This section provides information on the procedures to be
followed and on the systems and controls to be used in
the event an emergency situation is encountered during
machine operation. Prior to operation of the machine and
periodically thereafter, the entire operating manual, includ-
ing 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 Con-
trol Station and one at the Platform Control Station, will
immediately stop the machine when depressed.
CHECK MACHINE DAILY TO MAKE SURE EMERGENCY STOP
BUTTON IS IN PLACE AND THAT GROUND CONTROL INSTRUC-
TIONS ARE IN PLACE AND LEGIBLE.GROUND CONTROL STA-
TION
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 functions from the
ground. Place the power select switch in the ground posi-
tion 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 con-
nected, by a cable, to the manual descent valve on the lift
cylinder. Pulling the manual descent handle opens the
valve spool, lowering the platform.

Use of Ground Controls
KNOW HOW TO USE THE GROUND CONTROLS IN AN EMER-
GENCY SITUATION.
Ground personnel must be thoroughly familiar with the
machine operating characteristics and the ground control
functions. Training should include operation of the
machine, review and understanding of this section and
hands-on operation of the controls in simulated emergen-
cies.
Operator Unable to Control Machine
1. Operate the machine from ground controls ONLY
with the assistance of other personnel and equip-
ment (cranes, overhead hoists, etc.) as may be
required to safely remove the danger or emergency
condition.
2. Other qualified personnel on the platform may use
the platform controls. DO NOT CONTINUE OPERA-
TION IF CONTROLS DO NOT FUNCTION NOR-
MALLY.
3. Cranes, forklift trucks or other equipment which may
be available are to be used to remove platform
occupants and stabilize motion of the machine in
case machine controls are inadequate or malfunc-
tion when used.
