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 824
Service Bulletin/Repair Instructions
Altec has discovered that certain ST550/720/750/900 units built from January 2018 to December 2019 could have incorrect, damaged, or loose fasteners attaching the pressure regulator to its support bracket. Any of these conditions could lead to damage of the primary tank that the pressure regulator bracket is attached to. Altec requires the pressure regulator fasteners to be inspected on the affected units no later than the next scheduled service interval. This inspection can be completed by a customer in less than 15 minutes. If the inspection criteria are not met, order the Pressure Regulator Fastener Kit. Install the kit within 90 days of receipt.

The placard kit required depends on the unit model. Install the kit upon receipt. This installation is covered under the Altec Warranty Policy and can be performed by Altec, the customer, or the customerâs warranty provider.

If the customer or the customerâs warranty provider performs the installation, a warranty claim must be submitted to be reimbursed for the cost of the parts and/or labor.
SIL 781
Service Bulletin/Repair Instructions
The receiver hitch capacity and warning placards were not installed on the affected units. Use of the hitch at loads higher than the design ratings due to the lack of these placards can overload the receiver tube, resulting in damage to the receiver tube and/or the bumper. The Receiver Hitch Placards Kit is included with the SIL. Altec requires this kit to be installed by the next preventive maintenance interval.
