  • Page 33 SECTION 2 Pronar T663/4 T663/4 SILO • The trailer is designed to operate on slopes up to 8° . Driving trailer across ground with steeper slopes may cause the trailer to tip over as a result of loss of stability.

  • Page 34: Tyres

    Pronar T663/4 T663/4 SILO SECTION 2 • Do NOT exceed the trailer's maximum carrying capacity. Exceeding the carrying capacity may lead to damage to the machine, loss of stability while driving, scattering of the load and danger while driving. The brake system is adjusted to the gross weight of the trailer, exceeding the weight limit causes drastic reduction of basic braking effectiveness.

  • Page 35: Maintenance

    SECTION 2 Pronar T663/4 T663/4 SILO • Check the tyre pressure regularly. Air pressure in tyres should be also checked during the whole day of intensive work.
