HH = jet on the horizontal plane
VV = jet on the vertical plane
CC = round jet.
After choosing the type of spray required, close the regulating ring (3 - Fig.
G). Horizontal or vertical jets (HH-VV) are advisable for large surfaces. The
round spray (CC) is used for small items and difficult to reach areas (cor-
ners, edges, etc.).
WARNING! In order to use up all the paint in the tank, adjust the supply pipe
(12 - Fig. G) by unscrewing the nut (14 - Fig. G) and positioning the pipe in the
most convenient way, depending on whether the surface to be sprayed is mainly
horizontal (1 - Fig. I) or vertical (2 - Fig. I).
WARNING! Never press the trigger (8 - Fig. G) while setting the spray gun.
Setting the spray
When the machine is on the flow of air moves through the air hose (6 - Fig. A) and
exits through the spray gun (7 - Fig. A) via the butterfly nozzle (4 - Fig. G) in a
continuous stream. The paint is only atomised when the trigger (8 - Fig. G) is
pressed. To adjust the spray (1 - Fig. H) it is advisable to start with the adjustment
screw (5 - Fig. G) completely closed (turned clockwise, to the right). Open the air
regulating screw fully (17, Fig G, where fitted) (“+” mark to the top). Hold the
trigger (8 - Fig. G) down and slowly open the adjustment screw (5 - Fig. G) until the
paint is nebulised as required.
Spraying method
Put on the support belt (5 - Fig. A where fitted). Remove the gun from its
holder (8 - Fig. A) and aim it in the direction of the surface to be coated. The
gun must be moved evenly and must always be kept at a constant distance
from the surface to be coated and parallel to it. A distance (3 - Fig. H) of 10
to 30 cm is advisable, depending on the setting and the type of paint used.
It is especially important to move parallel to the surface of the object to be
coated in order to produce an even surface. Never use a rotating movement
as this could spoil the quality of the finish. The gun must be moved horizon-
tally when spraying vertically VV (2 - Fig. H) or vertical for spraying horizon-
tally HH (2 - Fig. H). The round spray CC (2 - Fig. H) is to be used at a greater
distance from the item to be painted. In all cases it is advisable to do some
tests on a piece of cardboard or wood before starting to paint. Each time
you change direction release the trigger (8 - Fig. G) and press it again when
the return movement begins (4 - Fig. H). Especially on large surfaces, this
will avoid overlap marks for the return passage.
OTHER USES OF THE TURBO COMPRESSOR
By connecting the inflation nozzle (14 Fig A where fitted) to the hose (6 Fig A)
the atomiser can also be used as a blower unit or to inflate airbeds or other
inflatable objects.
MAINTENANCE
WARNING! Before checking or carrying out maintenance on the ma-
chine, disconnect the power supply by removing the plug from the ma-
chine.
- Clean your machine regularly and care for it to ensure that it remains per-
fectly efficient and has a long working life.
Cleaning the gun.
WARNING! The gun must always be cleaned carefully immediately
after use. If the paint dries inside it will be very difficult to clean and there
is a risk of not being able to use it again.
WARNING! Do not use inflammable solvents to clean the gun. Clean
the gun in a well ventilated room, in accordance with the general safety
standards and electrical safety standards indicated above.
Switch the machine off and disconnect it from the power supply.
Remove the tank (1 - Fig. G) having made sure that all the coating material in
the gun has flowed back into the tank. Pour the remaining paint into its tin and
close it tightly.
Begin cleaning the tank (1 - Fig. G) by pouring a small amount of diluents into
it that is suitable for the type of paint involved, and that has a flash point of
more than 21°C.
Shake the tank with the diluents inside for a few seconds and then empty it.
Repeat this operation until the diluents that are poured out of the tank are
properly clean. Clean all traces of paint from both the inside and the outside of
the tank.
Clean the gasket (2 - Fig. G) under the tank cap, and check that it is not worn
or damaged.
To clean the other gun components proceed as follows:
1) Unscrew the ring (3 - Fig. G).
2) Remove the butterfly nozzle (4 - Fig. G).
3) Unscrew the adjustment screw altogether and pull it out (5 - Fig. G).
4) Remove the spring (6 - Fig. G).
5) Remove the needle (10 - Fig. G). It is best not to use tools. If the needle is
difficult to remove, unscrew the gland nut (11 - Fig. G).
Warning! If the gland nut (11 - Fig. G) is removed to extract the needle (10 -
Fig. G), do not lose any part of the gland assembly (16 - Fig. G).
Warning! Never use pointed metal objects to clean the nozzles and the air
holes on the spray gun (7 - Fig. A).
6) Use a spanner to remove the inner nozzle (9 - Fig. G).
7) Remove the flat washer (7 - Fig. G).
Put all these pieces in a receptacle for cleaning and proceed to clean them
using clean diluents (perhaps recommended by the paint manufacturer), and
use a paintbrush.
Also clean the inside parts of the gun and the suction hose (12 - Fig. G).
Before fitting these components again make sure they are properly dry.
Warning! Replace the components listed following the removal sequence in
reverse order.
It is strongly recommended that the inner nozzle (9 - Fig. G) be mounted
before the needle (10 - Fig. G).
During assembly take care with the gasket (7 - Fig. G) that has 4 orientation notches
that help with the positioning of the butterfly nozzle (4 - Fig. G). The gasket’s fixed
position is established by the tag sticking out of it at the bottom.
Warning! If you have removed the gland nut (11 - Fig. G), before closing add
a drop of grease (the needle must slide freely).
Warning! This equipment is fitted with a 3 mm nozzle (18 Fig G) for high
viscosity products. If this is changed make sure the screw (5 Fig G) is unscrewed
completely or push the trigger (8 Fig G) all the way in so that the needle does
not impede removal and installation on the inner nozzle (18 Fig G).
Warning! To replace worn washers (2 and 13 - Fig. G) proceed as follows:
- Unscrew the nut (14 - Fig. G).
- Remove the lower cover (15 - Fig. G).
- Remove the gaskets (2 and 13 - Fig. G).
Warning! Check the position of the gasket (13 - Fig. G) before tightening the
nut (14 - Fig. G).
Warning! For safety reasons and for the machine to work properly, the seal on
the tank is not entirely airtight. Even when it has been closed properly you may
detect a small amount of air escaping.
Cleaning the machine casing
Switch the machine off and disconnect it from the power supply.
Clean the machine casing (10 - Fig. A), the air hose (6 - Fig. A) and the gun
holder (8 - Fig. A) with a soft brush or clean damp cloth. Do not use any
detergents or solvents as these may damage the machine beyond repair. The
plastic parts are prone to damage by chemical agents.
Warning! Do not spray or soak the machine with water.
Cleaning and replacing the filter
Remove the filter cover (9 - Fig. A) using a screwdriver on the internal hook
(Fig. F). Check that the filter (11 - Fig. A) is clean by blowing it out and washing
it with soap. Replace if necessary.
Warning! Never use this machine without the air filter.
