Each time before connection of the machine inspect technical condition and cleanness of
contacts and sockets in tractor.
5.2.6
OPERATION NO. 6 – CHECKING BRAKING SYSTEM ACTION
After correct hitching of trailer to tractor and starting engine, compressed air is transferred to
braking system. If air pressure is too low trailer brakes will not be released and operator must
wait until pressure reaches at least 0.5 MPa.
After moving off, inspect braking by pressing tractor brake pedal. If trailer wheels brake
simultaneously on hard and level surface, the machine will not have a tendency to slide
sideways, if there is an insignificant pressure drop in braking system one should consider the
system to be reliable.
A metallic noise during braking, rapid heating of brake drums, uncontrolled slips sideways,
jerking of trailer, too low air pressure, sudden pressure drop or other symptoms appearing
during braking may be the cause of brake shoe lining wear, damage connectors or conduits,
unreliability of control valve or other serious system faults. In such instances immediately
stop and check condition of connectors and check tightness of system. If fault cannot be
detected and repair is impossible without breach of guarantee, contact service .and conduct
braking system diagnosis and execution of repair.
DANGER
Do not use the trailer with damaged pneumatic system.
Checking action of braking system:
•
daily.
5.2.7
OPERATION NO. 7 – CHECKING BRAKING SYSTEM TIGHTNESS
As a part of trailer maintenance, conduct inspection of pneumatic system leaktightness,
paying particular attention to all places of connection. Tightness of the system should be
checked at nominal pressure in system of approximately 0.8 MPa. In order to check system
tightness connect trailer to tractor and if necessary start tractor in order to bring system to the
