Maintenance
CAUTION
To avoid contaminating the fluid being sprayed, be
sure that the solvents used are compatible with the
fluid being sprayed.
To avoid getting solvent in the gun air passages,
never immerse the gun in solvent.
CAUTION
Methylene Chloride with formic or propionic acid is
not recommended as a flushing or cleaning solvent
with this gun or any other device with nylon or alu-
minum components, as it can damage these parts.
Cleaning
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 8.
1.
To clean the gun, flush it with a compatible solvent
until all traces of paint are removed from the gun
passages.
2.
Relieve the pressure.
3.
Wipe the outside of the gun clean with a solvent
dampened cloth.
4.
If the air cap and fluid nozzle need cleaning, re-
lieve the pressure, and remove the air cap (3)
from the gun. Remove the fluid nozzle with the
special nozzle wrench (21), supplied. Soak the
fluid nozzle in solvent and wipe it with a clean
cloth. Soak the air cap in solvent and scrub it with
a fine bristled brush (20). To clean the holes in the
air cap, use a toothpick or other soft implement to
avoid damaging critical surfaces.
CAUTION
Never use metal instruments to clean holes in the
air cap and nozzle. Metal instruments can damage
the holes in the air cap and fluid nozzle, resulting in
distortion of the spray pattern.
Lubricating
Lubricate the gun daily with light oil at the points
marked
in Fig. 3. Periodically lubricate the fluid
needle spring (7) with lightweight grease or petroleum
jelly.
