TROUBLE SHOOTING
If the line is not satisfactory, the cause could be one of the following reasons:
1. Paint is too thick and mixed properly.
2. If hoses or nozzle clogs, paint was not strained.
3. Nozzle tip is too small or too large.
4. Nozzle tip may be worn.
5. There may be an air leak in system.
6. Relief valve may need adjusting.
Proper lining will result from the correct adjustment of these variables and can only be
ascertained in the field because of the variations in the marking liquids and the desired
thickness being used.
