To avoid damage to the fluid nozzle and
>
electrode, the paint pressure and trigger
return spring tension MUST be released by
triggering the applicator while removing or
installing the fluid nozzle.
The applicator barrel MUST be tilted front
down to remove the fluid nozzle. Failure to
do so may allow paint to enter the air pas-
sages, thereby reducing airflow and dam-
aging the applicator barrel cascade. Appli-
cators may be flushed in lieu of tilting.
However, they must be either flushed or
tilted down during nozzle removal!
3. With a blade screwdriver, remove the pressure
reducer from the barrel by unscrewing it counter-
clockwise.
4. Install the new pressure reducer.
5. Install appropriate fluid nozzle, gently tightening
into place using the special multi-purpose applicator
wrench.
6. Reinstall appropriate air cap and retaining ring.
(See "Air Cap/Fluid Nozzle Selection Chart" in the
"Installation" section for proper combination of air
caps, fluid nozzles and pressure reducers.)

Proper selection of a fan control valve
>
is necessary to meet certain state codes
requiring 10 psi maximum air pressure at
the air cap when using HVLP technology.
Special gauges and test nozzles are
available to confirm the pressure output.
(See "Service Kits", in the "Parts Identifi-
cation" section for these parts.)
