Do NOT park trailer on slope.
2.1.7 TYRES
•
When working with tyres, the trailer should be immobilised with parking brake and
secured against rolling by placing chocks under wheel. Wheels can 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.
•
Inspection of nut tightening should be carried out after first use of trailer, after first
travel with load and then after 6 months use. In the event of intensive work, check
the nut tightening at least every 100 km. The inspection should be repeated
individually if a wheel has been removed from the wheel axle.
•
Avoid potholes, sudden manoeuvres or high speeds when turning.
•
Check the tyre pressure regularly. Pressure and tyres should be also checked
during the whole day of intensive work. Please note that higher temperatures
could raise tyre pressure by as much as 1 bar. At high temperatures and
pressure, reduce load or speed. Do not release air from warm tyres to adjust the
pressure or the tyres will be underinflated when temperatures return to normal.
•
Protect tyre valves using suitable caps to avoid soiling.
