When using a spray gun, how do you avoid air supply and painting problems?
What will be an ideal response?
To avoid air supply and painting problems:
| Check and replace oil and water filters and traps on a regular basis. | |
| If the system is not automatic, drain moisture from it daily. Draining the system in the morning allows more moisture to be removed because it is cool and has condensed. | |
| Replace air hoses as necessary. Deteriorated air hoses can also introduce dirt into the system. |
