Whether the joints, cylinders, floating oil seals, radiator plates, water pipe joints, etc. of the high-pressure pipe are leaked, and should be eliminated if necessary.

Whether the bolts of the air filter, muffler, roller bracket, track, working device, etc. are loose, if found, should be tightened.

Whether the electrical system is disconnected, short-circuited, or the terminal is loose, if it should be eliminated in time.

Inspection of engine oil sump oil quantity:

When the engine is stopped, take out the dipstick and check that the liquid level should be between the “H” and “L” scales of the dipstick.

If the water temperature gauge is in the normal range, then the oil dipstick should be taken to check that the liquid level should be between the upper and lower scale lines of the dipstick. To add oil, open the filler port and add. When checking the oil level, the vehicle should be parked on a level surface. When adding oil, do not raise the oil level above the “H” mark.
