# Service bulletin SIL 822

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 certain AT237 and AT248F aerial devices built from April 2017 through March 2020 might have insufficient slack in the hydraulic hoses at the riser between the lower and upper booms, which could lead to hoses rubbing on the metal surface of the riser. This could cause damage to the hoses and result in unplanned downtime. Altec requires the hydraulic hose routing to be inspected on the affected units no later than the next periodic maintenance interval or 90 days from the receipt of this SIL, whichever comes first. If the inspection criteria are not met, order and install the Hose Assembly Replacement kit. This inspection and repair are covered under the Altec Warranty Policy and can be performed by Altec, the customer, or the customer’s warranty provider. Altec will perform the work for free at an Altec facility.
