Service bulletin SIL 764

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 in the upper boom hose carrier on the affected units can become unsecured and slip out of place. This can expose the fiber optic lines to damage, resulting in intermittent operation or failure of the upper controls. Altec requires the following actions to be performed on the affected units no later than 30 days after receiving this SIL. • Inspect the hose sock in the upper boom using the Inspection Procedure beginning on page 2. • Have Altec make any required repairs.
