importance because loaded trailer's centre of gravity is higher, which reduces safety.
Driving near ditches or channels is dangerous as there is a risk of the wheels sliding
down the slope or the slope collapsing.
• Speed must be sufficiently reduced before making a turn or driving on an uneven road or
a slope.
• When driving, avoid sharp turns especially on slopes.
• Please note that the braking distance of tractor and trailer combination is substantially
increased at higher speeds and loads carried in the trailer.

4.6 UNLOADING

The trailer is equipped with hydraulic tipping system and suitable frame structure and the
load box allowing tipping sideways and to the rear. Tipping off the load box is controlled from
driver's cab using external tractor hydraulic system manifold. Unloading trailer is performed in
the following sequence:
• tractor and trailer must be placed to drive forwards on flat ground,
• immobilise tractor and trailer with parking brake,
• Tipping pins (connecting load box and lower frame) should be placed and properly
interlocked on the side which will be used to unload. Individual sockets are designed
so it is impossible to place them on the opposite diagonal side of the load box which
would damage the trailer,
• Open appropriate closures chute sliding gates (depending on the direction in which
unloading should take place). When opening take special care because load may
exert a great pressure on the walls,
• Using the manifold lever in the operator's cabin to initiate tipping of the load box,
pins connecting the load box with the lower frame are secured against falling out,
side wall hinge pins are protected against falling out.
