EMERGENCY OPERATION
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
IF THE PLATFORM OPERATOR IS PINNED, TRAPPED OR UNABLE
TO OPERATE OR CONTROL THE 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.
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 accident, thoroughly inspect the machine
and test all functions first from the ground controls, then
from the platform controls. Do not lift above 3 meters until
you are certain that all damage has been repaired, if
required, and that all controls are operating correctly.
5.5
INCIDENT NOTIFICATION
It is imperative that JLG Industries, Inc. be notified imme-
diately of any incident involving a JLG product. Even if no
injury or property damage is evident, the Product Safety
and Reliability Department at the factory should be con-
tacted by telephone and provided with all necessary
details.
It should be noted that failure to notify the Manufacturer of
an incident involving a JLG Industries product within 48
hours of such an occurrence may void any warranty con-
sideration on that particular machine.
