To the summer, because the working environment temperature is higher if coupled with improper maintenance will make the service life of weihe tractor greatly reduced.For weihe tractor summer maintenance must pay attention to the following points:

1. To keep the cooling system clean, it is necessary to clean the cooling system of the tractor thoroughly after the arrival of summer;

2, adjust the tractor fan belt tensioning degree, with the thumb in the middle of the tractor belt downward pressure deformation of 10 to 15 mm is appropriate, too loose, easy to slip, affect the fan rotation, resulting in insufficient wind, if too tight, easy to cause damage to the tractor belt axle;

3, appropriately reduce the pressure of tractor tires, the summer tire pressure had better be lower than the standard pressure of 20% to 30%, this can avoid the occurrence of a flat tire, work to timely check the tire tread, if you feel hot when the tractor should be parked in the shade to rest, but not by splashing cold water and air way to cool;

4. Select suitable fuel oil and lubricating oil for weihe tractor;

5. Adjust the specific gravity of electrolyte in tractor battery, and adjust the specific gravity of electrolyte in weihe tractor battery from 1.28 to 1.29 in winter to 1.25 to 1.26 in summer;To the tractor electrolyte level height to do more inspection, the level height should be 10 to 15 mm higher than the plate, if the water is insufficient to need to add distilled water in time.
