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 low flow rates or light viscosity fluid, select the smaller nozzle sizes.

For high flow rates or high viscosity fluid, select the larger nozzle sizes.

NOTE:

DTo help select the proper needle/nozzle size, a fluid pressure gauge may be connected temporarily to the gun fluid inlet to determine the fluid pressure. See Accessories, page 28.

DSee page 17 for troubleshooting information.
