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 unit you must have followed
each and every one of the steps described in the section
Stopping when work is finished (Section 12.2)
. 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) is located, by inserting in
both cases the product return hose (No. 2).
2.- Connect the unit to the compressed air network
(No. 9)
3.- When the solvent starts to flow through the
product return hose (No. 2) close the return key
(No. 3).
4.- Turn the pressure regulator control (No. 4) to
adjust the working pressure.

11. OPERATION
VERY IMPORTANT!!
Only if the whole process indicated in the section regarding DEPRESSURISATION, described in section 10,
has been correctly carried out will the unit be ready to be started and used again.
The incorrect observance of this Depressurisation process could lead to malfunctions in the equipment and
deterioration of its components.
Check and fill every day with the lubricant OILPACK (30090098), if necessary, the existing accommodation in
the gland (No. 34). Replace if dirty or damage.
1.- Insert the suction probe (No. 1) in the container with the
product to be applied.
2.- Turn the pressure regulator (No. 4) clockwise, until you
see that the product circulates through the unit and flows
through the return hose (No. 2).
Insert the product return hose (No. 2) in the actual product.
3.- Close the product return key (Nº 3).
4.- Turn the product regulator control (No. 4) to adjust the
required pressure to be applied, visible on the pressure
gauge (No. 7).
5.- Carry out an uncompromising application test by directing
the application on an earthed metallic container, WITHOUT
the air cap on the gun .
6.- Pull the trigger of the spray gun while maintaining part
of the same (for example the hand guard), in contact with
the container being sprayed.
In a few seconds the product will start to flow from the head
of the gun without the air cap. Keep the product flowing until
it there is a continuous flow (no air) through the head.
7.- Activate the gun's safety latch.
8.- Assemble the air cap on the gun.
9.- Adjust the Spray Pressure:
9.1 Adjust the spray pressure by turning the pressure
regulator control (No. 5) until the product flowing from
the gun is completely atomised.
To avoid spraying an excessive amount of product that
causes excessive misting, and produces premature wear
of the air cap and the components of the unit, always
use the lowest possible pressure to obtain the
performance and micronage expressed by the product
manufacturer (greater spray pressure does not mean a
better finish, while it does mean worse performance and
product transfer).
9.2 Once the pressure at which the product atomises is
determined, if a greater amount of product needs to be
applied, we recommend that, preferably, a larger air cap
is used instead of increasing the pressure.
9.3 To achieve the desired spray pattern, activate the
gun's safety latch, loosen the screw that fixes the air
cap and move it to the desired position.
9.4.-Tighten the air cap holder screw again.
During application, the amount of product applied to
areas with difficult access, reduced space, etc. can be
reduced by decreasing the travel distance of the trigger
when loosening the grip of your fingers on it.
Adjust the distance between the air cap and the object to
be sprayed (10 / 20 cm.) depending on the same, the product
to be applied and the working conditions, in order to increase
transfer and obtain a reduction in the amount of mist
depending on the air cap used in each case.
12. STOPPING
1.- Short stop
When stopping for a short period of time that does not pose
possible problems with catalysation or hardening of the
product inside the unit and accessories, keep the product
suction probe submerged in the product and apply the
procedure of Depressurisation (Section 10).
Disassemble the air cap and dip it in thinner.
2.- Stopping when work is finished
2.1.- Turn the pressure regulator control. (No. 4)
anticlockwise all the way (Minimum).
2.2.- Pull the spray gun trigger, holding it until no more
product comes out of the gun.
2.3.- Lock the spray gun trigger with the safety latch.
2.4.- Open the product return key (No. 3) to then be
able to recover the product remaining inside the unit.
2.5.- Turn the pressure regulator (No. 4) clockwise
until the product flows out of the product return probe
(No. 2), thus returning the existing product inside the
unit to its container.
The unit is now ready to be immediately cleaned.
