16. Breaking-in of new vehicle maintenance
Engine of new vehicle should be sure not to operate at the maximum power output during the breaking-in period to
keep best performance and superior efficiency as well as guarantee durable service life. Please drive cautiously and
pay more attention to abnormal phenomenon occurred during breaking-in period. Given break-in mileage of the
new vehicle is 5,000 km. please run at speed under 100 km/h in breaking-in period.
Preparation before breaking-in of the new vehicle
1.Wash the vehicle and check connection and tight situation of each place.
2.Check coolant storage in radiator and check each place of cooling system for leakage.
3.Check oil level of engine, transmission, drive axle, steering gear. If deficient, add and then check each place for
leakage.
4.Check and see if braking system works properly and leakage phenomenon exists at connections of all valves and
pipelines.
5.Check and see if phenomenon of loosing or clogging exists at each place of steering system.
6.Check and see if electric equipments, lamps and instruments work properly, check battery electrolyte level.
7.Check whether tire pressure has meet requirement.
8.Check and see if each transmission gear can engage properly.
Maintenance during breaking-in period
1.Running on smooth and good road surface.
2.Gear shifting smoothly and impact is not allowed. Neutral gear sliding is forbidden while engine stop. Emergency
brake should occur as few as possible.
3.Speed limitation during breaking-in period: first gear≤10km/h, second gear≤20km/h, third gear≤30km/h, fourth
gear≤50km/h, fifth gear≤60km/h, overspeed gear using can not be permitted during breaking-in period .
4.Load limit: No load within 250km and never overload after 250km.
5.Often pay attention to the temperature of transmission, drive axle, wheel hub and brake drum. If overheating
severely, find out causes and eliminate in time .
6.Pay more attention to keep pressure of engine oil and the temperature of engine coolant within normal range.
Maintenance after breaking-in period
1. Tighten cylinder head and bolts (inc suspension). Tighten torque please refer to corresponding instruction.
Tighten torques please refer to corresponding instructions.
2. Check valve clearance.
3. Check lubricant level of final drive and clean ventilation plug.
4. Replace engine oil
、
axle oil and oil filter element.
5. Replace hydraulic oil and oil tank filter of power steering hydraulic system.
6. Check connection of transmission control mechanism for looseness.
7. Check connections of steering gear for looseness and damage.
8. Tighten bolts and nuts of front and rear suspension(carry out when full load)
9. Check connections of chassis and driving system according to specified torques. Tighten torques please refer to
corresponding instructions.
10. Check hydraulic system components of steering mechanism for fixing and tightness
11. Lubricate and maintain vehicle according to maintain items at 5,000km.
12. Check complete vehicle for oil, water and air leakage.
