1) In the process of convenient use, the air gun is often used to clean up the dust and debris in the working space.

2) Regularly (at least once a month) use an air gun to remove dust and impurities in the oscillation chamber, working room, and lower cabinet.

3) Regularly (at least once a month) wipe the electrode roller and edge plate in the working chamber with a volatile solvent (such as toluene).

4) Regularly (at least once a week) check whether the phosphor copper sheet around the upper cover is in good contact with the yellow corner copper. If there is blackening or oxidation, it should be polished in time.

5) Regularly (at least once a week) check whether the position of the connecting rod flywheel is deviated. Under normal conditions: when the upper cover is closed, the flywheel hole is directly above; when the upper cover is opened, the flywheel hole is directly below. If it deviates, please adjust the corresponding micro switch in the chassis in time.

6) Clean the air inlet filter of the whole machine regularly (at least once a week or a month depending on the site conditions).

7) After turning on the power every day, turn off the "High Pressure", and the machine will run a cycle work program without load before entering work.
