4.6 PROPER USE AND MAINTENANCE OF TYRES
When working with tyres, the trailer should be secured against rolling by placing chocks
under the wheels. 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 wheel nuts after the first use of the trailer, every 2 - 3 hours
during the 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.
•
Regularly check and maintain correct air pressure in tyres according to Operator's
Manual (especially if trailer is not used for a longer period).
•
Air pressure in 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 the appropriate caps to avoid soiling.
•
Do not exceed the trailer's maximum design speed.
•
When the trailer is operated all day, stop working for a minimum of one hour in
the afternoon.
•
Observe the 30-minute breaks to let tyres cool down after driving 75 km or after
150 minutes continuous driving time whichever comes first.
•
Avoid potholes, sudden manoeuvres or high speeds when turning.
