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.
SIL 3077
Altec has learned that the Samlex inverter default threshold on certain units built from August 2022 to April 2023 may not be able to accommodate the 110 power accessories at the platform. This can result in the operator being unable to use the accessories during normal operation until the inverter charges the battery above the threshold.
SIL 3067
Altec has learned that a pressure regulator bolt spacer on certain ST550/720/750 spray trucks and SK430/560 spray units built from July 2020 to February 2023 might not have been installed on the pressure regulator bolt weldment, resulting in the hoses on the tank exceeding their rated pressure on the affected units.
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.
