The lubrication method of the internal machine:
(1) Lubricating parts: each oil hole on the machine head, lubricating the upper shaft and the parts connected to the upper shaft; the parts in the panel and the movable parts connected to each part; lubricating the presser foot bar and the needle bar and the parts connected to it; Wipe the movable parts of the lower part of the board and add less oil.
(2) Matters needing attention in maintenance of the inner line machine: After the work is completed, insert the needle into the pinhole plate, raise the presser foot, and cover the machine head with the machine cover to prevent intrusion of dust; when starting work, first check the main The machine parts, how light or heavy it is when you step on it, whether there is a special sound, whether the needle is normal, etc., if abnormal phenomena are found, it should be overhauled in time; after the machine has been used for a long time, a major overhaul should be carried out.
