Bulletin Summary
Altec has learned that certain AT35/37-G and AT40-G aerial devices built between February 2008 and January 2016 have power wiring for the 12V hydraulic oil reservoir heater which could be insufficient to carry the electrical current required to operate the heater. This could result in damage to the unitâÂÂs Power Distribution Module (PDM), causing the oil heater to stop operating. A kit has been developed to update the oil heater power wiring to carry the necessary current. Altec requires this kit to be installed on the affected units no later than the next preventive maintenance interval or 90 days from the receipt of this SIL, whichever comes first.
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.
