3. Chock all the tires safely and securely.
4. Allow the engine to cool down for several
minutes.
5. Raise the hood.
6. Check the coolant level of the reserve tank:
• If the engine is warm, the coolant level must be
between the full line and the low line.
• If the engine is cold, the coolant level must be at
the low line on the reserve tank.

●To prevent the engine from overheating.
●To ensure adequate air inflow.
(A)
Avoid injury!
●Before checking always allow the radiator to
cool down:
• the radiator is hot and can cause burns
• the build up pressure in the cooling system
can cause the coolant to spray out
explosively during removal of the radiator
cap
●Always shut off the engine.
●Allow the engine to cool down.
●Remove the radiator cap only when:
• the radiator and the engine are sufficiently
cooled down that can be touched with bare
hands
●When removing the radiator cap, always:
• loosen the radiator cap to the first stop
• the preceding action releases excessive
pressure on the radiator
• fully remove the radiator cap once the
pressure has been released completely
●For tractors equipped with a coolant reserve
tank:
• add coolant or water to reserve tank, not to
the radiator
