Maximum air pressure required to
assure compliance of 10 PSI Max.
Cap Pressure - this reading must be
taken at the spray gun handle inlet
fitting.
Figure 1 Baffle
Air cap number located on face of
cap - cap number must correspond
with baffle number to assure 10 PSI
cap pressure.
To prevent damage to the fluid tip
(3) or fluid needle (30), be sure to
either 1) pull the trigger and hold
while loosening or tightening the
fluid tip or 2) remove fluid needle
adjusting screw (34) to relieve
spring pressure against needle
collar.
Note
When replacing the fluid tip or
fluid needle, replace both at the
same time. Using worn parts can
cause fluid leakage. Lapped sets
are available for most pressure
feed combinations. See Chart 2.
Also, replace the needle packing
(22) at this time. Lightly lubricate
the threads of the fluid tip before
reassembling. Torque to 20-25 ft.
lbs. Do not overtighten the fluid
tip.
If the air cap is changed, the
baffle must
also be changed.
Use of incorrect baffle
and cap set will result in substandard
performance and or improper air cap
pressures. See Chart 1 for ordering infor-
mation.
Never completely immerse in solvent as
this is detrimental to the lubricants and
packings.
