Service bulletin SIL 779

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Altec has discovered that the protective fabric hose sock used on the hoses running from the fiberglass upper boom to the platform may extend into the insulating portion of the upper boom. This can cause the dielectric performance of the unit to be reduced if the sock has absorbed water or oil. Altec requires the hose sock length to be inspected on each unit and shortened if necessary to keep it out of the insulating portion of the boom. The inspection and repair must be completed no later than the next regular maintenance interval.
