Tyres; Maintenance - PRONAR T680 Operator's Manual

SECTION 2
• Do NOT attempt to enter the trailer load box while travelling.
• Do NOT park the trailer on a slope.
• When using the trailer with the middle wall extensions, there is an increased risk
of loss of trailer stability, trailer overturning, failure of the trailer's structural
elements, insufficient visibility of the elements of the trailer's body, uncontrolled
movements of the load box on uneven terrain and the risk of overloading. Do not
use trailer on public roads when middle wall extensions are installed.

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.
• 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.
• Avoid potholes, sudden manoeuvres or high speeds when turning.
• Check the tyre pressure regularly. 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.
• Protect tyre valves using suitable caps to avoid soiling.

2.1.8 MAINTENANCE

• During the warranty period, any repairs may only be carried out by the Warranty
Service authorised by the Manufacturer. After the expiry of the warranty period it
