7.1.
A faulty spray is usually caused by improper cleaning or dried material around the fluid nozzle tip or in the air cup - use a brush and
solvent to remove. never use metal instruments to clean the air cup or paint nozzle. these parts are carefully machined and
any damage to them will cause a faulty spray. if either the air cup or paint nozzle is damaged, the part must be replaced before a perfect
spray can be obtained.
dried material in a dirty side port restricts
passage of air. Greater flow of air from the
cleaner side port forces the fan pattern in the
direction of the clogged side.
dried material around the outside of the fluid
nozzle tip restricts the passage of atomizing air at
one point through the centre opening of the air
cup and results in the pattern shown.
this pattern can also be caused by a loose air
cup.
A split spray or one that is heavy at each end of
the fan pattern and weak in the middle is usually
caused by too high an atomization air pressure or
by attempting to get too wide a spray with thin
paint.
1. Worn needle packing permits air to get
into the fluid passageway. this results in
spitting.
2. dirt between the paint nozzle seat and
body or a loose paint nozzle will cause the
gun to spit.
3. A loose or defective joint between the pot
and gun can cause spitting.
dissolve material in the side ports with solvent, then
blow the gun clean.
do not poke the orifice with a metal instrument.
remove the air cup and wipe off fluid tip using a rag
dampened with solvent.
tighten the air cup.
check supply pressure and reduce if over 50psi.
Adjust the air atomisation valve to reduce pressure and
adjust paint needle if required.
check spray pattern on a test panel.
1. tighten the packing screw or, in severe cases,
replace the packing.
2. remove the fluid nozzle, clean the back of the
nozzle and the nozzle seat in the gun body using a
rag dampened with solvent.
3. tighten or replace.
