2. New vehicle break in
2.1 Precaution on new vehicle break-in
2.1.1 The break-in must be done for 12 hours, equally for each speed (I forward, II forward and reverse).
2.1.2 During the break-in period, the loaded weight must not exceed 70% of the rated load.
2.1.3 Pay attention to the lubrication. Change or add grease according to the prescribed time.
2.1.4 Pay attention to the temperature of transmission, torque converter, front/rear axles, brake disc and brake drum. Do troubleshooting if overheat occurs.
2.1.5 Check the tightness of bolts and nuts on each part.
2.1.6 During the brake-in period, it is better to load incompact material, and the operation should be gentle.
2.2 Perform the following work after 8 hours of break-in.
2.2.1 Completely check the tightness of bolts and nuts on each part, especially those on cylinder cap, exhaust pipe, front and rear axles, rim and drive shaft.
2.2.2 Clean the primary and fine oil filters, and fuel filter.
2.2.3 Check the tension of fan belt. Check if the battery is properly charged by generator
2.2.4 Check the specific weight and the remaining amount of battery liquid. Make sure that the battery terminal is firmly connected.
2.2.5 Check the transmission oil level.
2.2.6 Check the airtightness in hydraulic system, pneumatic system and brake system.
2.2.7 Check the firmness of fasteners on operation lever and throttle lever.
2.2.8 Check the connection in electrical system, the condition of generator, lighting and turning indicators.
2.3 After the break-in period is finished, perform the following work.
2.3.1 Clean the screen in transmission oil pan and change new oil.
2.3.2 Change engine oil.
