If the trailer is pneumatically connected with the tractor in a correct manner (line 1 and 2), the
black push-button should be pulled out; the trailer's wheels are blocked by pulling the red
push-button out – figure (3.8).
4.10 PROPER USE AND MAINTENANCE OF TYRES
•
When working on the tyres, chocks or other objects without sharp edges should
be placed under the wheels of the trailer to prevent it from rolling. Wheel may be
taken off the trailer axle only when the trailer is not loaded.
•
Repair work on the wheels or tyres should be carried out by persons trained and
entitled to do so. This work should be carried out using appropriate tools.
•
Inspect tightness of wheel nuts after the first use of the trailer, every 2 - 3 hours
during first month of work and then every 30 hours of use (travel). The inspection
should be repeated individually if a wheel has been removed from the wheel axle.
Wheel nuts should be tightened according to recommendations provided in
section 5 MAINTENANCE.
