EMERGENCY OPERATION

Use of Ground Controls

NOTICE
KNOW HOW TO USE THE GROUND CONTROLS IN AN EMERGENCY 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 equipment
(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 OPERATION IF
CONTROLS DO NOT FUNCTION NORMALLY.
3. Cranes, forklift trucks or other equipment which may
be available are to be used to remove platform occu-
pants and stabilize motion of the machine in case
3121641
machine controls are inadequate or malfunction when
used.

Platform Caught Overhead

If the platform becomes jammed or snagged in overhead
structures or equipment, do not continue operation of the
machine from either the platform or the ground until the
operator and all personnel are safely moved to a secure
location. Only then should an attempt be made to free the
platform using any necessary equipment and personnel.
Do not operate controls to cause one or more wheels to
leave the ground.

Righting of Tipped Machine

A forktruck of suitable capacity or equivalent equipment
should be placed under the elevated side of the chassis,
with a crane or other suitable lifting equipment used to lift
the platform while the chassis is lowered by the forklift or
other equipment.

Post-Incident Inspection

Following any incident, thoroughly inspect the machine
and test all functions first from the ground controls, then
from the platform controls. Do not lift above 10 feet (3
meters) until you are secure that all damage has been
repaired, if required, and that all controls are operating
correctly.
