SCHEDULED TECHNICAL MAINTENANCE
FUELS
Summer diesel oil as per ČSN 656506 for the period between 1.4. and 31.10.
Winter diesel oil as per ČSN 656506 for the period between 1.11. and 31.3.
Note: Analogously, suitable types of fuels have to be used abroad, too.
Alternate fuel: Natural Diesel (bio-diesel oil)
Note: Tractor operation with bio-fuel requires the use of REP hoses in the fuel system. Use of bio-fuel in-
creases consumption, reduces the output by approx. 5%, and requires engine oil exchange after 200 Mh. The
bio-fuel has aggressive effects on the painted surfaces
LIQUIDS FOR COOLING SYSTEMS – TRACTORS Z 8641 - Z 11441
FRIDEX – STABIL, FRIDIOL 91 or FRICOFIN S and de-mineralized water in the proportion 1:1,5 (when re-
plenishing, keep to that ratio).
The non-freezing fluid for the exchanges abroad must contain ingredients protecting all the materials (includ-
ing rubber and cylinder head gaskets) of the engine cooling system.
CAUTION!
1. In the Z 8641 - Z 11441 tractors it is forbidden to make use of water without non-freezing fluid!
2. After two years of operation, exchange the cooling fluid.
3. The FRIDEX – STABIL and FRIDIOL 91 fluids may be mixed together. Mixtures with the fluids of other
manufacturers have not been verified!
