It is better to lubricate the China spray gun and parts lubricated by light machine after working every day. Due to normal wear and aging, the sealing ring, spring, needle valve and nozzle must be replaced regularly. The replacement shall be carried out according to the manufacturer's instructions.
Excessive oil will flow into the paint and oil passages, causing coating defects. Therefore, great care must be taken during lubrication, and the quality of coating will be reduced after oil and paint are mixed.
Do not soak the entire spray gun in the cleaning solution for a long time, which will harden the sealing ring and destroy the lubrication effect.
In order to obtain the best repair effect, different spray guns should be used under different coatings and conditions. It is recommended that each person be equipped with four spray guns, one for primer and intermediate coating, one for topcoat and varnish coating, one for silver powder coating, and one small repair spray gun for spot repair. If these spray guns are kept in good cleaning and working order, it will save a lot of adjustment and cleaning time when changing guns.
