[Replacement]
The lubricating oil should be completely replaced within 1000km during the running-in period of a new vehicle; after the running-in period, the
lubricant should be replaced every 4000km or so.
1. Turn off the engine after running for 3 minutes, and place an oil container under the engine oil drain bolt.
2. After 3 minutes, drain the lubricating oil from the engine (Caution: don't get burned by the engine or lubricating oil). Unscrew the oil bolt, loosen
the nut, and take out the filter cover, spring, filter element, etc. of the machine.
3. After draining the oil, the drain bolt and filter cover must be cleaned; replace the filter element and check whether the sealing ring is intact. If it is
EN
damaged, replace it with a new one; then install the filter element, spring, and sealing ring and filter cover.
4. Inject about 2L of new lubricating oil from the filler port. If you replace the new filter element, you need 2.2L of new lubricating oil. Check and
confirm that there is no oil leakage, and then install the filler plug.
5. Run the engine at different speeds for 3 minutes. During operation, check whether the disassembled parts are leaking. Wait for the engine to
stop for 3 minutes. In the idling state, the oil level is still lower than the scale line under the oil window, and an appropriate amount of lubricating oil
should be added. It must be checked again for leaks.
Common reasons for lubricating oil deterioration:
1. Lubricating oil temperature is too high and spontaneously deteriorates.
2. Lubricants with different labels are mixed together and deteriorated.
3. There are more and more metal shavings caused by friction of machine parts.
4. There are many dust and impurities in the lubricating oil barrel.
5. The gap between the piston and the cylinder is too large to leak exhaust gas, and carbon slag is generated when the fuel is burned.
