Cleaning
1. Flush the spray gun as described on page 6.
2. Relieve the air pressure.
3.
Remove the air cap and clean the fluid nozzle with the supplied cleaning brush and
solvent or waterborne cleaning solution compatible with the paint you are using.
NOTE:
Use only properly sized tools designed for nozzle cleaning to clean the nozzle
orifice. Contact your Nordson representative for nozzle cleaning kits.
Lubrication
See Figure 4. The trigger pin (18), valve pin (12B), and paint needle (6) should be
lubricated with silicone-free oil daily.
