EVOX DOT 4+

Liquid for the cooling system of the tractors

FRIDEX - STABIL, FRIDIOL 91 or FRICOFIN S and demineralised water in the proportion of 1:1.5 (replenish
the mixture in this proportion).
Antifreeze liquids for replacement abroad must contain anti-corrosion additives protecting all materials (incl.
rubber and head gaskets) of the cooling system of the engine.
CAUTION!
1. Water without an antifreeze mixture must not be used in the tractors!
2. Replace the cooling liquid after two years of operation. The FRIDEX - STABIL and FRIDIOL 91 liquids can
be mixed together.
3. Miscibility with liquids of other manufacturers has not been verified!

Fuel for Zetor engines which are equipped with diesel paricle filter

Diesel complies with EN 590 standard
IMPORTANT NOTE!
By using motor oil with elevated sulphur content, the service life
of diesel particle filter can be significantly reduced.

Urea (urea solution AUS 32)

Urea a highly pure aqueous urea 32.5% solution used as a reducing agent NOx for additional treatment of
exhaust gases.
The product is labelled as urea or AUS 32 (AUS: Aqueous Urea Solution).
Add only solution adhering to prescribed specifications.
Specification
DIN 70070
ISO 22241-1
ASTM D 7821
Note:
The urea solution AUS 32 is known in USA and North America as Diesel Exhaust Fluid (DEF).
The lifetime of urea without the loss of the quality is influenced by storage conditions.
It crystallizes at -11°C and over +35°C it initiates hydrolytic reaction which means that a slow
decomposition to ammonia and carbon dioxide begins.
It is essential to protect unprotected vessels from direct sunlight.
