Hydraulic brake liquid for the tractors
Liquid for the cooling system of the tractors
Coolant and demineralized water in the ratio of 1:1.5 (carry out refilling of the mixture using this ratio).
While changing or refilling the cooling fill in the engine always use a coolant complying with the prescribed
specifications.
Do not use water without an antifreeze for the cooling of a tractor!
Carry out a renewal of the coolant after two years of operation.
Fuel
Diesel oil complying with the regulation of EN 590
Paraffin impurities or additional additives in fuel are not allowed for engines with Common-
Rail injection.
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.
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.
