12. Cleaning
The spray gun, hoses and the rest of the unit must be cleaned with the appropriate thinner, in
order to remove any remaining product after each use. The useful service life of the unit depends
largely on the effectiveness of the cleaning process.
The unit must be cleaned:
- Before using it for the first time, in order to eliminate the traces of
maintenance oil that the equipment comes with from the factory.
- After each use.
- When proceeding to apply a different product (different colour or
characteristics) to what we are currently using.
Before proceeding to clean the pneumatic pump you must have followed each and every one of
the steps described in the section Stopping when work is finished (Section 10.2).
This implies that the unit and its accessories must be depressurised and without any product
inside.
Always use an appropriate thinner when cleaning the unit. Always use water for waterborne
products, for other products always use whatever is recommended by the manufacturer of the
product to be applied.
1.- Add the thinner to the external container where the suction probe (No.1 fig.2) is located, by
inserting the product return hose (No.2 fig.2).
2.- Turn the pressure regulator (No.4 Fig.2) clockwise, until you see that the product circulates
through the unit and flows through the return hose (No.2 Fig.2).
3.- When the solvent starts to flow through the product return hose (No.2 fig.2) close the return
key (No.3 fig.2).
4.- Turn the pressure regulator control (No.4 fig.2) to adjust the working pressure.
5.- Pull the spray gun trigger, holding it until the sprayed product is clean thinner and free from
the product previously applied.
It is considered that the unit and its accessories are totally clean when the product sprayed
through the gun, and that circulating through the product return probe (No.2 Fig.2), is clean
thinner and free from the product previously applied, meaning that the process must be
repeated as many times as necessary.
Once the unit and its accessories are clean, and as a prior step before definitively stopping
it, the Depressurisation procedure described before in Section 10.1 of the Manual must be
applied.
Clean the Suction Probe filters or the product cup and those of the spray gun.
Remove any remains of product from the gun, hoses and the rest of the unit with a cloth soaked
in thinner.
Keep gasket areas free of accretions and foreign bodies.
The air cap is a precision component. Any deformation, especially in the product outlet orifices,
may cause malfunctions in its operation and incorrect or deficient quality spraying.
If necessary, dip the air cap in thinner in order to soften the remains of product or dirt. Once
softened, blow the cap with compressed air until any remains of product and thinner are
eliminated.
