COOLING SYSTEM !
WARNING
Check and service the cooling system according to the instructions given in this manual. Do not remove the cap when the engine is hot. The cir-cuit is still under pressure and you could be scalded. •
If the level in the radiator is low, but full in the coolant reservoir, check for an air leak in the hose connecting the radiator to the coolant reservoir. If the problem persists, consult your local dealer.

Engine coolant WARNING
!
Boiling engine coolant can spray out if the radiator cap is removed while the system is still hot. To remove the cap, allow the system to cool down, turn the cap to the first notch and wait until there is no more pressure. Then remove the cap. Only fill ethylene-glycol engine coolant in the cooling system. Use good quality ethylene-glycol that has a high boiling point, with no additives to prevent leakage. Do not use non approved anti-rust additives. Anti-rust additives and ethylene-glycol can mix and work against each other, thereby reducing anti-corrosion protection, forming deposits in the cooling system and causing damage to the cooling system and radiator. Consult your local dealer for suitable engine coolant.

Engine Coolant Level in Coolant Reservoir The machine must be parked on flat level ground. Do not remove the radiator cap. On no account must the coolant reservoir level be higher than it was the day previously. If it is, check the level in the radiator. See “Radiator level”. The level of engine coolant should be checked when the engine is cold.
•
PROCEDURE 1. 2.
To access the engine see “Engine Access”. The level in the coolant reservoir should be between the “FULL” and “ADD” marks. If necessary, remove the reservoir cap and add coolant to the reservoir until the level reaches the “FULL” mark on the coolant reservoir.
3. 4.
Close and lock the engine bonnet. Remove the support strut and lower the loader attachmen
