3. Place the retaining nut over the air cap and

Removal
1. Remove the air cap from the applicator (refer to
"Air Cap - Removal" in the "Maintenance" section).
2. Tilt the applicator forward and pull the trigger to
make sure that all fluid in the applicator is drained
out.
3. While holding the applicator assembly with the
trigger pulled back, remove the fluid nozzle with
the open-end of the special multi-purpose wrench.
† The applicator barrel MUST be tilted
front down to remove the fluid nozzle. Fail-
ure to do so may allow paint to enter the
air passages, thereby reducing airflow and
damaging the applicator barrel. Applicators
may be flushed in lieu of tilting. However,
they MUST be either flushed or tilted during
nozzle removal!

† To keep the needle/electrode from
unscrewing from the needle shaft, the
applicator's trigger should be actuated to
pull the needle/electrode away from the
fluid nozzle.
NOTE
Cleaning and Inspection
1. Use a suitable solvent to clean the fluid nozzle
2. Examine the fluid nozzle for damage to the air
passages and the fluid nozzle tip. Also, exam-
ine the needle seat for damage or wear. If any
damaged or any worn areas are found, the fluid
nozzle must be replaced.
Figure 19: Air Cap, Fluid Nozzle, and Nut
† If the fluid nozzle is replaced, there is
a good chance that the needle/electrode
assembly will need to be replaced also. A
worn needle/electrode assembly may not
always seat well in a new fluid nozzle.
