A faulty spray is usually caused by improper cleaning or dried material around the fluid nozzle tip or in the air nozzle. Soak these parts in a
solvent that will soften the dried material and remove with a brush or a cloth. Never use metal instruments to clean the air or fluid nozzles.
These parts are carefully machined and any damage to them will cause a faulty spray. If either the air nozzle or fluid nozzle is damaged, the
part must be replaced before a perfect spay can be obtained.

PoSSIBLE cAuSE
Dried material in a side port restricting passage of air. Greater
flow of air from the cleaner side port forces 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 nozzle and results in the pattern
shown.
This pattern can also be caused by a loose air nozzle.
A split spray or one that is heavy on each end of a 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 material.
1. Dried out packing around the material needle valve permits
air to get into the fluid passageway. This results in spitting.
2. Dirt between the fluid nozzle seat and body or a loosely
installed fluid nozzle will cause the gun to spit.
3. A loose or defective swivel nut on the syphon
cup or material hose can cause spitting.

Dissolve material in the side ports with thinner, then blow the gun
clean. Do not use metal instruments to clear parts.
Remove the air nozzle and wipe off fluid tip using a rag dampened
with thinner. Tighten the air nozzle.
Adjust air pressure/fan width.
1. Unscrew the knurled nut slightly and place two drops of machine
oil on the packing then replace the nut and finger tighten.
In extreme 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 thinner.
Replace the nozzle and secure it tightly against the body.
3. Tighten or replace the swivel nut.
