First remove the waste oil from the tank, place the old oil container under the oil pan, open the oil drain bolt, and discharge the waste oil. When you leave the oil, try to let the oil drip for a while, and make sure the waste oil is discharged cleanly. Oil through the use of, will produce a lot of impurities, if the replacement of the discharge is not clean, easy to plug the oil circuit, resulting in poor oil supply, resulting in structural parts wear.

2. Remove the old oil filter

Move the old oil container to the bottom of the machine and remove the old filter. Be careful not to let waste oil smear inside the machine.

3. Preparation of oil filter before installation

There are two ways to install the oil filter. The common ones are vertically installed, and many small digging machines are installed horizontally. The installation is not the same, so filled with oil is also divided into two types: the first oil filter installed vertically, it is to the oil pump through a pipeline access, the installation method generally recommended to replace the oil filter to filter the oil filled.

If the new oil filter is not filled with oil, the new internal filter will produce air resistance, the car caused a short time inside the machine lack of oil lubrication, will cause structural parts wear. The advantage of the vertical mounting method is that the filter core has better sealing properties and very little oil leakage occurs.

4. Install the new oil filter element

Check the installation position of the oil filter oil outlet, clean up above the dirt and residual oil. Before installation, first in the oil outlet position of a sealing ring, and then the new oil filter slowly screwed up, pay attention to the oil filter do not screw too tight, the general case is tighten by

5. To the oil tank with new oil 

Finally, the new oil into the oil tank, when necessary, to prevent the oil funnel, pour in the external engine. After filling, check again lower engine leaks. If there is no leak, check the dipstick, to see whether the oil filling to the line, we suggest to add it to the daily work of everyone on the line. To regularly check the oil dipstick, less than the line to replenish.
