SECTION 6 - EMERGENCY PROCEDURES
6-2 – JLG Lift – 3121261
Platform or Boom Caught Overhead
If the platform or boom becomes jammed or snagged in over-
head structures or equipment, rescue platform occupants prior to
freeing the machine.
Boom Movement Prevented By Boom Control System
Lowering the boom onto an object or structure, with the boom at
high angles, may cause the boom control system to prevent
movement of the machine. This can include movement necessary
to lift the boom off the object. Movement of the boom can be
regained by observing the following:
1. Shut off the engine.
2. Rescue platform occupants prior to freeing machine.
3. Use cranes, forklifts or other equipment to stabilize motion
of the machine as required.
4. From the ground control position, use the Auxiliary Power
System to carefully raise the boom off the object.
5. Once clear, restart the engine and return the platform to the
ground.
6. Inspect the machine for damage before continued use of the
machine.
6.4 EMERGENCY TOWING PROCEDURES
Towing this machine is prohibited, unless properly equipped.
However, provisions for moving the machine have been incorpo-
rated. For specific procedures, refer to Section 4.
