TAB. 5.4 PARKING BRAKE BRAKING FORCE
PARAMETER UNIT VALUE
Parking brake braking force kN 6.5
ATTENTION!
Parking brake braking force, is the braking force of all sand spreader wheels.
5.5 PNEUMATIC SYSTEM OPERATION
As a part of sand spreader 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 600 kPa (6.0 kg/cm
2
).
If conduits, seals or other system elements are damaged, compressed air will escape in
these damaged places with a characteristic hiss. Lack of system tightness may be exposed
by covering checked elements with washing fluid or other foaming preparations, which will
not react aggressively with system elements. Damaged seals or conduits, causing leaks
should be replaced. If the cause of the system leak is the outflow from a piston, control valve
body or braking force regulator should be taken to authorised repair provider for repair or
replacement of parts. Condensation collecting as water should be removed from air tank
periodically. In order to do this open out drain valve (2) placed in lower part of tank - figure
( 5.5A ). The compressed air in the tank causes the removal of water to the exterior. After
release of the valve stem, the valve should automatically close and stop airflow from the tank.
Annually before the winter period unscrew drain valve and clean off accumulated dirt.
Replace copper seal.
Contact of pneumatic leads with oils, greases, petrol etc. may cause damage and accelerate
ageing process. Bent conduits, permanently deformed, cut or worn should be replaced.
