portion).
Anti-freeze for refilling abroad should contain anti-corrosive additives pro-
tecting any materials (including rubber and head sealing) of the engine
cooling system.

1. It is forbidden to charge the tractor cooling system with water without
antifreeze!

FUEL
Diesel fuel for summer period from 01.04. to 31.10.
Diesel fuel for winter period from 01.11. to 31.3.
Notice: Similarly suitable types of fuel should be used abroad.
Mixed fuel Natural Diesel (bio diesel fuel).
Notice: Tractor operation with the bio diesel fuel requires equipment of the
fuel system with the REP hoses. Use of the bio diesel fuel increases con-
sumption, decreases output by about 5%, and requires oil change in the
engine after 200 hours of work. It also has corrosive effect on painted parts.
