Caution! The hydraulic oil must be replaced in accordance with the operating manual of the
coupled tractor, but at least every two years.
6.2. Pneumatic system servicing
Periodically check the pneumatic system tightness. Thoroughly inspect every connection. Check the leak-
tightness of the system at the rated pressure of approx. 600 kPa (6.0 kG/cm2). After decoupling the tractor, the
10-minute pressure loss in the vessel should not exceed 2% of the initial pressure value which is set directly after
decoupling the trailer. If any lines, seals or other system components are damaged, the compressed air will escape
from the damaged points, producing a distinctive hissing noise. Replace any damaged seals or lines which cause
the leaks.
If the leak is located at the actuator, replace the device. If any mechanical damage is found on the vessel (e.g.
dents, cracks, etc.) or if the vessel has been exposed to high temperature, replace it.
Drain all water from the pneumatic system at least twice a year, especially before winter. To do this, press
and hold the lever that extends from the drain valve screwed into the bottom part of the tank until the water flow
stops. Release the lever. The tank should remain leak tight.
6.3. Periodic maintenance
The periodic technical inspection of the spreader should be performed every 50 operating hours.
Due to safety considerations, it is necessary to perform functional tests of the service and
parking brakes, the power transmission system and the wheel system.
