10. Test run the vehicle (at a speed of about 10 km/h for at least 1 minute), briefly run
the retarder (the highest gear) at the beginning, and then cancel it.
11. Engine shut down;
12. Loosen the screw plug at the oil drain plug;
13. Check the oil level, and fill the oil until it overflows if necessary;
14. After using the new gasket, tighten the oil spill port screw plug.
CAUTION:
1.Please check the oil level below 40ºC temperature.
2.The correct position of the oil surface is at the bottom of the overflow
port, that is, the oil overflow position.
3.Check the oil level after the test drive, which is the correct refueling
process, so as to ensure the accurate refueling volume and the split
heat exchanger. Check after the test drive for about 5 minutes, to
prevent the heat exchanger idling.
Add oil after maintenance
1. Add oil to the transmission and check the oil level can be done only after the
vehicle is horizontally parked and the engine is turned off.
2. For vehicles with transmissions installed horizontally, the transmissions shall be
placed horizontally before refueling, otherwise the quantity of refueling is not

the transmission nameplate information;
4. The amount of fuel added is only a reference value, which may vary with the type
of transmission and installation angle;
5. For refueling quantity and tightening torque, please refer to the technical
parameters section;
6. If PTO is assembled, the amount of refueling shall be considered;
7. If the heat exchanger and retarder are installed separately, please consider the
amount of oil in the connecting pipe.
CAUTION:
Insufficient oil in the transmission will lead to transmission damage and
accident risk
WARNING:
Insufficient oil in the transmission will result in retarder failure, brake
torque weakening or failure.
8. Loosen the screw plug at the oil spill port, add oil from the oil spill port to the
overflow, install the gasket and tighten the screw plug at the oil spill port.
