4.4 Service
Service for your FoldTrailer FT752 is defined as operations which require cunning personnel, like your trailer dealer or
authorized vehicle-mechanical staff. Generally are all parts of this trailer replaceable. This, together with a careful
maintenance and proper use can give your trailer a long life.
The folding system of this trailer is based on a principle that all suspension parts are flexible until the drawbar is being
folded out and latched. Then the entire suspension system becomes sideways stable under a pre-tension phase. This
pre-tension is making the trailer suspension compact, resulting into excellent driving conditions and good loading
capacity. Although it requires all related parts to be in good condition, clean, lubricated etc. to obtain the required
flexibility for the folding. It also requires the suspension adjusting bolts to be correctly installed with correct
camber
angles of
the wheels and correct pre-tension moment.
Especially the lower axle adjusting bolts may have to be
tightened after first time of heavy loading to maintain a positive wheel camber and suspension
compactness.
