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-3026
Service Bulletin/Repair Instructions
Altec has learned that certain DRM 12 and DRM 12he chippers built from 2014 to 2022 could develop fatigue cracks in the upper pivot housing weldment. If not addressed, these cracks can lead to damage of the chipper. The customer should inspect the upper pivot housing weldment on the affected chippers. Complete this no later than 30 days from the receipt of the notice.
CSR 513
Service Bulletin/Repair Instructions
Engine Power Source (EPS) has launched a technical bulletin for MVP controllers with potential memory loss. These controllers have a display on Altec DC1317 and DRM12 chippers. Affected units have the potential for the display to go blank due to a voltage drop during the boot-up cycle. This can be fixed by reloading the firmware and configuration files. Please refer to the communication from EPS. No action is required unless you are experiencing issues.
SIL 751
Service Bulletin/Repair Instructions
Altec has discovered that some of the fuel hoses used on chipper engines do not meet the proper specifications. While the fuel hose is not a safety concern, the hose does not meet the EPA permeation requirements per 40 CFR 1048.105. It is extremely important for the correct fuel line to be installed to minimize emissions to the atmosphere from vapor permeation through the body of the fuel line. Understanding the importance of this regulatory requirement, Altec and its customers will make a concerted effort to repair the units in a timely manner. Altec requires that the fuel lines on each unit be inspected for the correct type. The inspection must be completed at the next periodic maintenance interval but no later than 90 days after the receipt of this SIL.
SIL 705
