If production downtime is to be short,
>
the fluid lines may not require flushing, de-
pending on the coating material being used.
If the solids in the material settle slowly, the
lines will not need to be flushed as soon af-
ter shutdown as with fast settling solids.
The paint being used and the length of
downtime will determine the need for flush-
ing. Metallic paint and primer will require
flushing sooner than other types of coating
materials.

If the coating material is fast settling and

the fluid lines are not flushed soon enough,
the internal passages may become clogged.
This can lead to excessive downtime for
repair.

To avoid damage to the fluid nozzle,
>
needle/electrode, the paint pressure MUST
be released by triggering the applicator prior
to removing the tip.
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 airflow and
damaging the applicator barrel/cascade.
Guns may be flushed in lieu of tilting. How-
ever, they must be either flushed or tilted
down during nozzle removal!
The control unit power MUST be off
>
when removing the nozzles and/or during
any applicator maintenance.
