ATTENTION
Do NOT jerk the trailer forwards if load is bulky or reluctant to pour and does

Do NOT move off or drive when load box is raised.
Do not unload the trailer the second trailer is connected.
Do NOT tip load box in strong gusty winds conditions.
Tipping the load box must be done on hard and level ground.
Tipping may only be performed when trailer is hitched to tractor.
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.
