# Service bulletin SIL 776

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

Regular replacement of the return line hydraulic filter is required as part of the periodic maintenance on an aerial device. Altec has discovered that on the affected units the hydraulic reservoir was mounted in a location that does not allow access for replacing the return line hydraulic filter. Altec requires that a repair is performed to provide filter access no later than the next periodic maintenance interval. The required repair kit depends on the type of body on the unit. The affected units are T40P aerial devices built on Ford F\-750 chassis from July 2017 through December 2018
