# Service bulletin SIL 3021

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

The rear out and down outriggers on certain LS60 aerial devices built from July 2018 to April 2022 might contain a dual bonded hose with an externally attached electrical cable in the horizontal leg to operate the hydraulic cylinder and proximity interlock sensor in the vertical leg. Altec has learned that the hose/cable assembly can have a reduced life expectancy due to abrasion sustained during extension and retraction of the horizontal leg. Altec has developed a product improvement using a triple\-bonded hose with the electrical cable contained inside the center hose of the assembly.
