Service bulletin SIL 738

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

The Hot Line Insulator Wash-Trailer (HLIW-T) tank lid should be open when filling the tank with water. If the tank lid is left closed while filling, pressure can build up in the tank forcing the lid to swing open possibly causing personal injury. Altec is providing two English placards warning of the pressurized lid condition. Place the placard on the lid in the locations shown on Figure 1.
