Bulletin 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.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
