Tyres; Maintenance - PRONAR T900 Operator's Manual

SECTION 2
• Please note that the braking distance of the tractor and trailer combination is
substantially increased at higher speeds and loads.

2.1.6 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 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 every 10,000 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. 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.

2.1.7 MAINTENANCE

• The trailer should be cleaned each time after finished work.
• 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
is recommended that possible repairs to the trailer be performed by specialised
workshops.
• In the event of any fault or damage, do not use the trailer until the fault has been
fixed.
• During work use the proper, close-fitting protective clothing, gloves, protective
goggles and appropriate tools.
