Service bulletin SIL 3099

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 learned that on certain Altec units equipped with air suspension built from April 2020 to June 2023, some operators may be dumping the chassis airbags before deploying the outriggers. This can cause the airbags to become damaged. Altec has developed a new placard outlining the proper operating procedure.
