Check procedure
If the oil level gauge shows that the oil level is lower than the normal oil level, the oil should be full. Note that the oil filling should not exceed the "FULL" position
[note]
① When checking the oil level, the machine should be kept on a level ground.
② Clean the oil filling port before adding oil to ensure that no dirt enters the oil.
③After adding oil, wait 5-6 minutes before checking the oil level. If you check immediately after adding, it may still show that the oil level is low.
④Choose suitable engine oil.
⑤ Spilled engine oil may cause a fire, so the spilled oil should be wiped off immediately.
