The JUKI HZL-NX7 sewing machine does not need regular oiling as it comes pre-lubricated from the factory. However, if oiling is necessary, apply 1-2 drops of sewing machine oil to the magnetic ring after turning off the machine, removing the presser foot, throat plate, and bobbin, and cleaning the area. Wipe away excess oil with a cloth before testing the machine.
