Engine Performance Limitation; Drive Away - Zetor MAJOR Operator's Manual

Engine Performance Limitation

The engine control unit will automatically limit engine
performance in the following cases:
If the coolant temperature exceeds 110ºC, the
overheating indicator on the dashboard comes on (A).
Stop working and keep the engine running at idle until the
coolant temperature decreases and the indicator goes off.
If the coolant temperature does not drop while the engine
is running at idle, stop the engine and check coolant
contents.
If coolant level in the equalizing reservoir falls under
a critical limit, a maintenance notification of COOLANT
LEVEL will show up on the dashboard display (B)
Check joint tightness in the engine cooling system and
coolant contents. Top up the missing contents up to the
upper mark labelled with MAX.
Loosen the overpressure plug only after the
coolant cools down! Scalding danger!
