PRONAR T679/5 SECTION 5

The tailgate position should be checked during trailer operation. If the tailgate position is
incorrect, a gap will occur between the side edge of the tailgate and the rear surface of the
load box. If both surfaces do not adhere precisely to each other, the load box is not tight and
scattering of bulk materials may occur. When adjusting the tailgate, reduce the gap to
minimum.
Scope of adjustment activities
Hitch the trailer to tractor. Park machine and tractor on level surface.
Connect conduits of the tailgate hydraulic system.
Prevent the trailer from rolling by placing chocks under the wheels. Immobilise
tractor and trailer with parking brake.
Start the tractor's engine, open and close the tailgate. Check if closed tailgate
adheres to the trailer's load box.
If the gap is detected during visual inspection, adjust the position of closed

Using adjustment bolt (3), set the tailgate position to reduce the gap between
the surfaces of the load box and tailgate to minimum.
