Reassembly of the air cleaner elements
Bleeding the hydraulic circuit of the hydrostatic steering
Replacing the hydrostatic steering hoses
The hoses must be replaced after four years from the production date (the date is indicated on their surface)
or after 3500 hours of work of the tractor or immediately after discovering signs of their damage (hose
sweating, local buckling, leaks of the working media around the end pieces and on the hose surface,
abrasion of the hose surface to the metallic reinforcement, damage of the outer yarn braiding in the case of
low-pressure hoses).
In case of a pump failure or after stopping of the engine the steering capability is maintained,
but the required steering force gets higher. You can drive the tractor at a reduced speed to the
nearest workshop. The steering wheel must not be held in the limit turning angle positions for a long
time (the maximum time is 20 s); otherwise the oil in the hydrostatic steering circuit is heated up
excessivel
.
Carry out a reverse procedure in order to mount air filter
cartridges back on.
While mounting the cartridges back on mind:
- The cleanness of contact surfaces
- That the cartridges must not lose their shape while being
mounted and they must not vibrate after their mounting
has been finished
- That after having closed the filter with the cover you mus
ensure a perfect tightness of the entire filter

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.
