3. Check the oil lever of engine, gearbox and rear axle, final transmissions, front wheel

drive axle, steering oil tank and hydraulic system. If it is not enough, then supply

again.

4. Fill some fuel and cooling water.

5. Check air pressure of the the tires.

6. Check proportion and height of battery electrolyte.

7. Put Shuttle shift lever, PTO shift lever ,range shift lever and gear shift lever on

“netural” position.Disengage the 4WD. Lifting mechanism control at lowered

position.

3.2 Running-in the engine without load 

Running-in engine for 15 minutes without load.Start the engine in accordance with the 

procedure specified in the Instruction Manual, let the engine running-in 7 minutes in 

hight speed, 5minutes in mid speed, 3 minutes in high speed. 

During the running-in of engine without load, should carefully check the work condition 

of engine, air compressor and hydraulic pump.Observe if have abnormality, noise and
