WARNINGS
MAINTENANCE AND
CLEANING
CORROSIVE PRODUCTS
Solvents such as trichlorethane and
chloromethylene (dichlorethane) can
chemically react with the aluminum that
makes up much of the gun and cause
dangerous explosions. Do not use the
gun with halogenated hydrocarbon
solvents (ethyl chloride, trichloride)
which could cause explosions on contact
with aluminum parts.
MAINTENANCE
Routine maintenance does not require
particular interventions as his
components are free from lubrication.
To ensure a flawless operation of the
gun over time it needs to be cleaned
daily or in any case at each end
work to prevent residue dried product
inside the paint circuit. To proceed to
maintenance, close the air of
supply to the system, discharge the
residual pressure in the paint tube,
remove the air tube from the gun e
remove the paint tube from the gun.

case of adjustments of the gun with the
system functioning.
CLEANING
Discharge the pressure, disassemble the
finger protection and the nozzle. Check
that the packings are not worn-out,
otherwise replace them. Carefully clean
the nozzle, dip it in thinner to dissolve
residue inside it. Blow commpressed air

ADJUSTMENT SEQUENCE
1. Always use high pressure hoses for
connections. Before using the
equipment, check that the
connections and pipes do not have
holes, folds or cracks.
2. Connect the paint inlet hose to the
connection (A) of the gun.
3. Select the nozzle (2) and the gun
butt filter most suitable for the job
to be performed.
4. Always work with the minimum
pressure necessary to obtain the
desired results. Increasing the
pressure does not improve the
quality of the painting but can create
a faster wear of the nozzle.
5. If the yield is not optimal, change
the micro-nozzle for a larger one
without increasing the pressure.
