OPERATING INSTRUCTIONS
Page 28 Mega-Trailer
12.2 Brake System Components
- Both service line hose couplers must be correctly connected and close tightly.
- The air filters, i.e. the filter elements (1) fig. 13 in both pipelines must be cleaned at regular intervals. If this is
not carried out, the correct functioning of the components (valves) down-line has no protection. The pipelines
must be depressurised before cleaning the air filters. Push in the floor cover (2) and release the retaining slide
(3), then the filter element can be removed and cleaned. The system remains in working condition even if the
filter element is blocked.
- The trailer brake valve (5) is protected against impurities by the air filter and requires no special maintenance.
- The trailer brake valve is controlled via the brake line (yellow hose coupler) with the aid of regulated pressure
from the trailer control valve on the tractor side. The trailer compressed air vessel (8) is filled via the supply line
(red hose coupler). The brake pressure regulator (4) flanged to the trailer brake valve can be manually adjusted
to the respective load situation on the trailer.
The adjustment data for the ALB regulator (14) can be found next to the type plate on the front right-hand side of
the vehicle.
The brake pressure regulator can be set to Full Load, Half Load, Empty and Release. The Release position enables
the uncoupled vehicle to be manoeuvred into place.

On self-loading trailers with ALB regulators, the brake is released by pressing the release valve fig. 14.
The
compressed air vesse
l (8) (capacity 30 l.) is design-tested. Modifying or welding any part is not permit-
ted. The
drain valve
(9) on the underside of the vessel must be activated after approx. 20 operating hours.
The
brake cylinder
(6) piston must pull back completely when the brakes are released, i.e. the piston rod must
make contact with the piston bottom.
