Deported
spray
Thisdeformation is due to a defect in the central spray. It
is necessary to clean the head as described above and
the nozzle. Also check:
•The head is well centered on the nozzle,
•The nozzle is not too big (needle and nozzle must be
adapted),you work with a sufficient needlen opening,
• With an almost closed needle, the product supply to

Default inverse of the previous one:
•Either the paint flow rate is excessive for the adopted
spraying air pressure - You should increase the
spraying air pressure and reduce the paint flow rate.
• Either the paint is too thick - You must then dilute it.
Jerky product

The gun is machine-gunned. The phenomenon is caused
by air entering the paint circuit:
•The container containing the paint may be empty -
Refill with paint.
•The nozzle is not tightened properly and does not fit
