4.7 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. 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.
•
Inspect tightness of nuts after the first use of trailer, after the first travel under load
and then every 6 months of use or every 25,000 km. In the event of intensive
work, check the nut tightening at least every100 km. The inspection should be
repeated individually if a wheel has been removed from the wheel axle.
•
Regularly check and maintain correct pressure in tyres according to Operator's
Manual (especially if trailer is not used for a longer period).
•
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.
•
Tyre valves should be protected with caps to avoid soiling.
•
Do not exceed the trailer's maximum design speed.
•
When wrapper is operated all day, stop working for a minimum of one hour in the
afternoon.
•
Adhere to 30 minutes rest for cooling tyres after driving 75 km or after 150
minutes continuous travel depending on which occurs first.
•
Avoid potholes, sudden manoeuvres or high speeds when turning.
