After the water-based paint spray gun is used, spray and clean it with the thinner of the sprayed paint until the paint channel of the spray gun is cleaned. Otherwise, the paint in the gun will dry and block, which will affect the normal use of the gun.
Specific cleaning method of water-based paint spray gun:
1. Turn off the compressed air, remove the paint storage tank, pour the paint in the gun back into the paint storage tank, and pour the paint in the tank into the container;
2. Pour about 1/4 volume of solvent into the paint storage tank for flushing, install the paint storage tank, connect the compressed air, and rock and spray several times;
3. Disassemble the nozzle, clean it with solvent and install it; wipe off the paint on the gun body.
When washing the water-based paint spray gun, you should pay attention to the following points:
1. When brushing, use a soft brush, prohibit the use of metal brushes, and do not use hard objects to poke and scrape, so as to prevent wear of the nozzle and change the shape of the jet;
2. Avoid soaking the spray gun directly in the solvent to prevent the residual paint from adhering to the machine parts and dissolving the lubricating oil on the gun. Use a soft cloth dipped in solvent to wipe it;
3. The knurled parts on the gun are adjusted by hand, avoiding the use of pliers;
4. Regularly drip lubricating oil at the needle valve and bolt pin shaft;
5. Regularly use light grease or Vaseline to lubricate the needle valve and needle valve spring, and do not use oil containing silicon.
