Post-season service
After the working season, the cultivator should be thoroughly cleaned, the damage to
the varnish coating should be repaired, and the stripped working surfaces of the teeth,
discs, strings and roller rings, as well as the threads of the adjusting screws, should be
washed with "Antykor" paraffin and protected against corrosion with "Antykor 1" grease,
and a full lubrication should be carried out. It is advisable to store the machine under a
canopy when not in use. However, if this is not possible, the condition of the protection
should be checked from time to time and, if necessary, the rain-washed grease should be
replenished.
The cultivator should be stored in a place that poses no danger to persons
or the environment
. The machine, when uncoupled from the tractor, should be supported
on firm and level ground. Also, components dismantled from the machine should be stored
securely supported on the ground, excluding possible uncontrolled movement.
Clean the piston rods of the hydraulic cylinders during winter and when the machine
is not in use for a long period of time, and protect them with vaseline or acid-free
grease to protect them from corrosion.

Operation of the hydraulic system
Maintenance of the hydraulic system (Fig. 17, 18, 19, 20) consists of a visual
inspection for leaks. Remember to put plugs on the quick-release couplings. Oil leakage
at the connections of the hydraulic lines should be tightened. If this does not rectify the
fault, the component or hose must be replaced with a new one. Leakage occurring outside
the connector - the leaking hose must be replaced with a new one. Mechanical damage
also requires replacement of the component. It is recommended to replace the hydraulic
hoses every 5 years.
The appearance of oil on the piston rod of a hydraulic cylinder should be checked
for the nature of the leak. When the piston rod is fully extended, check the sealing points.
Minor leaks characterised by wetting of the piston rod with an "oil film" are permissible
(defective sealing ring). In the event of heavier sweating or the appearance of drops, the
unit should be switched off while the fault is being rectified (defective seal).
