CONTROL OF PNEUMATIC SYSTEM

• Hitch trailer to tractor.
• The tractor and trailer should be im-
mobilized with the parking brake. Ad-
ditionally, place wedges under the
rear wheel of the trailer.
• Start the tractor to supplement the air
in the trailer braking system tank.
In double conduit systems, the
air pressure should be around
6.5 bar.
• Switch off the tractor engine.
• Check the system components with
the tractor brake pedal released. Air
leakage is not allowed.
Pay special attention to cable
connections and brake cylinders.
• Repeat the system check with the
tractor brake pedal depressed.
The help of another person is
required.
DANGER
It is forbidden to use the trailer with inefficient braking
system.
Repair, replacement or regeneration of pneumatic
system components may only be carried out in a
specialized workshop.
In the event of a leak, the compressed
air will leak out in places of damage with
a characteristic hiss. The system leak can
also be detected by coating the checked
elements with washing liquid or other
foaming agent, which will not aggressively
affect the elements of the installation.
Damaged elements should be replaced or
sent for repair. If the leak appeared around
the connections, user can tighten the con-
nector on their own. If air still leaks, re-
place the connector components or seals
with new ones.
