Danger - Raising the Trailer

NEVER crawl under the trailer unless it is on firm and level ground and resting on properly placed and secured jack stands.

The possibility exists of the trailer falling thus causing equipment damage and severe bodily harm even death!

DANGER - Trailer Inspection

When performing trailer inspection and maintenance ac-

tivities, you must jack up the trailer using jacks and jack

stands.

When jacking and using jack stands, place them so as

to clear wiring, brake lines, and suspension parts (i.e.,

springs, torsion bars). Place jacks and jack stands in-

side of the perimeter strip on the supporting structure to which the axles are attached.

Torsion Suspension

The mounting bracket (Figure 49) of the torsion suspension assembly is bolted directly to the trailer frame. Except for periodic inspection of the bracket’s fasteners to the trailer frame, no other suspension maintenance is required on the axles.
