pump, motor or cylinder malfunction; rubber particles on the filter that may indicate
deterioration of hoses, o‑rings or other rubber components.
3. Fuel
filters.
4. Fan belt adjustment and excessive wear (diesel engine only).
5. Hydraulic hoses for cracks, leaks and buckling, and signs of excessive abrasion on all
hoses and pipes.
6.
Hydraulic pumps and motors for cracks or leaks, leaks at joints and gaskets, loss of ope‑
rating speed, excessive heating of fluid, and loss of pressure.
7. Hydraulic cylinders for drifting caused by fluid leaks across the sealing valve or the
piston, rod seal leakage, scored and damaged cylinder rods, and unusual noises or
vibration.
8. All safety mechanisms for wear and response time.
9.
Interlocks, gradient warning system, and limit switches.
10. All chain and cable mechanisms for setting and worn or damaged parts.
C –ANNUAL INSPECTIONS
These inspections must be performed annually.
A complete inspection of the aerial platform must be performed by a qualified operator. The
inspection must comply with the requirements of points A and B and must include, but not
be limited to, all critical and suspect areas and all accessible structural elements and welds,
such as the following:
1. Stabiliser and stabiliser housing (boxes), including the underside of the housing.
2. Platform rotating, elevating, and levelling mechanisms.
3. Main turret rotating mechanism.
4. Brakes.
5. All secured points.
6. Arm sections, pins, cylinder rods, and levelling devices.
7. Switches for wiring and all electrical connections.
8. JLG safety bulletins enclosed with the manual.
D –STRUCTURAL INSPECTION
A structural inspection is required to verify the structural soundness of critical components
of the aerial platform and must be performed:
1. 10 years after the date of manufacture and every 5 years thereafter.
2. After every accident that may actually, presumably, or potentially cause damage and
affect the structural soundness or stability of the aerial platform. Such accidents include
short circuits, impacts, falls, collisions, or cases of overstress or stability failure.
3. After a change of ownership, unless a complete service history is provided, including
