on page 16 when you stop spraying and
whenever you are instructed to relieve
the pressure.
Procedure:
1. Relieve the system pressure.
2. Remove the air cap assembly (1, 12) and gun
shroud (2). See Fig. 14.
3. Wipe the fluid nozzle (14), shroud (2), and exterior
of the gun (P) clean with a cloth dampened in
solvent. Avoid getting any solvent into the air
passages. Whenever possible, point the gun down
while cleaning it.
4. If it appears that there is paint inside the fluid
nozzle (14) air passages, remove the gun from the
line for servicing.
5. Clean the air cap (12) with the soft bristle brush
and solvent or submerge the air cap in suitable
solvent and wipe it clean.
CAUTION
Do not use metal tools to
clean the air cap or fluid
nozzle holes as this could
scratch them, and make
sure the electrode wire is not
damaged. Scratches in the
air cap or nozzle or a dam-
aged electrode wire can dis-
tort the spray pattern.
