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.
TERE-080621-002
PN695 is to improve the sound of the PAL lanyard attachment on TL units. The PAL system is an operator aid to alert the operators if their fall protection lanyard is not connected to the boom tip when lifting the boom out of the rest.
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.
