SCHEDULED TECHNICAL MAINTENANCE
FUELS TAB. 7
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 TAB. 8
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!
LIQUIDS FOR COOLING SYSTEMS – TRACTORS Z 11741 TAB. 9
Use only prescribed antifreeze
AKROS FLUID
into cooling system of engine at tractor Z 11741 Forterra!
CAUTION!
1.
In the Z 11741 tractors it is forbidden to make use of water without non-freezing fluid!
2.
Exchange after 1200 hours or at least after two years of operation.
3.
It is not allowed to add water or another fluid into this antifreeze!
