end caster locks into a position parallel to the side of the bed.

Steering System
Inspect for proper operation and tracking.
Using a 6" straight edge, check to see if the three linkage mechanism pivots
are slightly over center when steering is engaged. Check for any
interferences.

the Steering Plus™ Steering System wheel.
The Steering Plus™ Steering System wheel hub should not be able to be
rotated by hand.
