Selecting the Proper Needle/Nozzle Kit
The spray gun's needle/nozzle kits range in size to
provide different fluid flow rates.
As a general guideline, use the fluid nozzle that will
give the required flow with the needle fully triggered at
the lowest fluid pressure.
For high flow rates or high viscosity fluid, select the
larger nozzle sizes.
For low flow rates or light viscosity fluid, select the
smaller nozzle sizes.
