Engine; Fuel System; Oil System; Cooling System - Zetor UTILIX HT Series Operator's Manual

Engine

1. After starting the engine and warming up the cooling circuit (indicator needle in the green field), put it into
a high load.
2. If excessive black smoke is visible, check the air filter paper element, fuel injection pump, and injector
nozzles.
3. Do not run the engine for more than 2 minutes without load. It is better to stop the engine than to let it idle.

Fuel system

1. Always use only diesel as fuel in the fuel system.
2. After finishing work, it is advisable to fill the tank with fuel to prevent condensation of water in the tank.
Replace the fuel filter if the engine misses or stalls. If these instructions are not followed, the service
life of the injection pump and nozzles is shortened. There is also excessive smoke and excessive
diesel consumption.

Oil system

1. Always use the recommended type of oil.
2. Every day before starting the engine, check the oil level using the dipstick and add fuel so that it is
between the minimum and maximum levels.
3. Change the engine oil. If replacement is required, replace the filter and the O-ring together.

Cooling system

1. Check the fan belt tension regularly. Adjust if necessary.
2. Check the radiator coolant regularly.
3. If it is necessary to replace the radiator cap, use an original spare part.
4. Do not disconnect the thermostat, but replace it with a new one if necessary.
5. Do not change the water in the radiator too often.
Note:
1) Always resolve any fuel or oil leaks immediately.
2) Perform regular maintenance; failure to do so may increase fuel consumption by up to 25%.
3) Regularly check that the cylinder head bolts are tight to the correct torque and adjust the valve
clearance. In case of any technical questions or malfunctions, contact an authorized service.
4) Check the tire pressure and adjust to the prescribed pressure if necessary.
Note:
1) Always purchase original spare parts from an authorized dealer/distributor.
2) Always service the tractor only at an authorized dealer / distributor.
* For any other information, contact your nearest authorized dealer / distributor.
