BLEEDING THE HYDRAULIC CIRCUIT
OF THE HYDROSTATIC STEERING
1 - Start the engine and let it run at the
idle speed for approx. 1 minute.
2 - Turn the steering wheel several times
to both the sides at the idle speed of
the engine.
3 - At the maximum engine speed turn
the wheels with the steering wheel 3
times alternately slowly and quickly to
both the sides up to the limiting stops
of the wheels.
4 - Stop the engine and lower the tractor
onto the front wheels.
During all the steps of bleeding of
the hydrostatic steering observe
the oil level in the tank to avoid
aspiration of air to the steering
system.
After the end of bleeding check or re-
plenish the oil level to the dipstick mark.
Check all the connections and lines for
leaks.
