It is allowed to operate with trailers 2PTS-4-887А, having body capacity of 20 and 45 cubic meters, at speeds up to 15 km/h, as they have lesser stability. To prevent damage to rear wheel fenders, avoid sharp turnings of these trailers and thrower 1RMG-4. Hinge of trailers (2PTS-4-785А, etc.) should be secured from turning to avoid its cramping. During the operation the fork of TSU-1Zh should be fastened on the crossbar of drawbar hitch with two pins. It is prohibited to operate with the fork, fastened with one pin. Before operation make sure that pins and pivot bolts of drawbar hitch fork are securely fastened by cotters.
