AIR CAP
Removal
1. While holding the barrel with one hand, loosen the
retaining nut using the other hand.
2. Unscrew the retaining nut completely and remove the
air cap.
Cleaning and Inspection
1. Use a suitable solvent to clean the air cap. (Refer
to "Suitable Solvents for Cleaning Vector R90/70
Applicators" in the "Maintenance" section.)
2. Examine the air cap for damage to the air horns, face,
and any air passages. If any of these areas are damaged
or worn, the air cap should be replaced.
Reinstall
1. Check the fluid nozzle to ensure that it is tightly screwed
into the barrel.
2. Place the air cap over the electrode wire of the needle/
electrode and set it onto the fluid nozzle.
3. Place the retaining nut over the air cap and begin
screwing it onto the barrel.
4. Before securing the retainer nut to the barrel, position
the air cap for the desired spray pattern position.

sure that all fluid in the applicator is drained out.
Figure 18: Removal of Fluid Nozzle
CAUTION
!
The applicator barrel
MUST
be tilted front down
to remove the fluid nozzle. Failure to do so may allow
paint to enter the air passages, thereby reducing air-
flow and damaging the applicator barrel. Applicators
may be flushed in lieu of tilting. However, they
MUST
be either flushed or tilted during nozzle removal!
NOTE
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.
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.
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, examine the needle seat
for damage or wear. If any damaged or any worn areas
are found, the fluid nozzle must be replaced.
