4. Clean the oil in the oil hole, and then clean the oil barrel of the refueling pump.
5. Clean the feed pellet machine grease block, install the grease block, start to oil with a bucket of new oil, and check whether the refueling part is leaking. Check whether the oil seal at the rear end of the rotor is leaking oil, and replace the oil seal if necessary.
6. After refueling for ten minutes, turn on the machine for about five minutes, and then stop the machine until the main shaft is cleaned with new oil.
