Hitching, Unhitching; Safety Principles When Working With Tyres - PRONAR T740 Manual

2.4 HITCHING, UNHITCHING

• Be especially careful when attaching the machine. Ensure appropriate visibility
and check that persons assisting in hitching the machine are at a safe distance
from danger zone.
• When attaching, there must be nobody between the trans-shipment trailer and the
tractor.
• The trans-shipment trailer and tractor must not be attached if the hydraulic oil in
the two machines is of different types.
• While connecting the trailer to the tractor, use the appropriate hitch. The height of
the trans-shipment trailer drawbar eye should be optimally adjusted to the height
of the hitch. After hitching the trailer check the drawbar eye safeguard.
• When connecting the hydraulic conduits to the tractor, make sure that the
hydraulic systems of the tractor and trans-shipment trailer are not under pressure.
• After completing trans-shipment trailer hitching, the support leg must be
maximally raised and mechanical raising/lowering crank placed in neutral
position.
• While lowering the support, take particular care with regard to the danger of being
crushed.
• The agricultural tractor to which the trans-shipment trailer shall be hitched must
fulfil the requirements stipulated by the trailer's Manufacturer.
• When disconnected from the tractor the trans-shipment trailer must be secured by
parking brake and wedges.

2.5 SAFETY PRINCIPLES WHEN WORKING WITH TYRES

• Check the tyre pressure regularly.
• When working with tyres, the trans-shipment trailer must be immobilised with the
parking brake and prevented from moving by placing wedges under the wheels. A
wheel may be taken off the trailer axle only when the trailer is not loaded.
