Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.

Service Bulletin/Repair Instructions
Some customers have reported a crack in the side plate of the mounting frame on some AT200A aerial devices built on Ford F450/F550 chassis from 2011 to 2016 with steel utility bodies. Altec requires that each unit be inspected for cracking in the mounting frame side plate no later than the next periodic maintenance interval. Altec requires the kit to be installed within one year of the inspection if the side plate has no cracking or within 90 days of the inspection if the side plate is partially cracked. If the side plate is fully cracked, the unit must be taken out of service until the kit is installed. The inspection and repair are covered under the Altec Warranty Policy and can be performed by Altec, the customer, or the customerâs warranty provider. All welds must be applied by a welder having the AWS D1.1 3G qualification for steel. An Altec Mobile Service technician can perform this inspection but is not able to perform this repair. Altec will perform the repair for free at an Altec facility.

Altec has discovered that the protective fabric hose sock used on the hoses running from the fiberglass upper boom to the platform may extend into the insulating portion of the upper boom. This can cause the dielectric performance of the unit to be reduced if the sock has absorbed water or oil. Altec requires the hose sock length to be inspected on each unit and shortened if necessary to keep it out of the insulating portion of the boom. The inspection and repair must be completed no later than the next regular maintenance interval.
