CAUTION!
In order to increase the lifetime of pump operation, the hydraulic system
shall be refilled after drainage of the working fluid from the oil intake pipe as follows:
1. Refill oil into the hydraulic tank through the oil filler port; in doing so, oil level shall
reach the middle of housing of filter 11 (Fig.46).
2. Start the engine.
3. Pump out the system by making 3...5 tractor turns from end to end and by moving
the linkage up and down 4 times.
4. Refill oil into the hydraulic tank.
Installation and operation of high-pressure hoses
During installation and operation of hoses observe the following rules:
a) do not admit any twist of hoses during installation and dismantling, check the cor-
rectness of installation of hoses by straightness of the marking strip;
b) install hoses on the tractor in a manner preventing their rubbing or damaging by
parts of assemblies of the tractor in operation;
c) do not expose hoses to mechanical loads as it can lead to their destruction;
d) do not permit the ingress of fuel and lubricants on the outer rubber layer of hoses.
7.5.10 Maintenance of tractor wheels
Check of the condition of tyres and wheels
a) Every day before tractor departure examine the tyres and wheels, clean the tyres
from foreign matter jammed in tyre treads. Wheel parts with cracks and tyres with de-
fects reaching the cord or passing through should not be permitted for operation.
b) Protect tyres from the ingress of fuel, oil and other petroleum products.
c) Tighten wheel nuts crosswise in a uniform manner, using a special wrench sup-
plied along with the tractor.
d) To provide for a more uniform wear of the tyre tread pattern, once in every 1900
–
2000 engine hours interchange positions of the front and rear wheels while observing
the direction of rotation of wheels in view of the arrow applied on the tyre surface.
Check of air pressure and tyre inflation pressure
a) Undo the valve cap.
