Vehicle report
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.
PUN-3288
Altec has updated maintenance and operator’s manuals for all LR7, LR8, and LRV units to bring better visibility to the inspection of the outrigger/subbase connection. These welds are critical to the longevity of the aerial device.
SIL-3195
Altec has learned that the affected units could experience issues with the lanyard detection interlock system being out of adjustment due to the improper installation of the fiber optic cable on the transmitter, as well as signal interference from nearby transmission lines. These defects have been resolved by implementing adjustment criteria, improving cable installation, addressing interference issues, and updating the firmware.
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
