• Useing of the tire pressure gauge
m Note
– T
he optimum air pressure of the car tyre not only
provides safe performance and durability of your
tyres – using the right tyre pressure, recommended
by the automobile manufacturer, also can safe fuel.
– You will find the details on the comfortable minimum
pressure for your tyres in the instruction manual of
your vehicle or e.g. at the door pillar or behind the
petrol cap.
– The compressed air, to refill the tyre, has to be oil
free. Do not connect an oiler ahead of the unit. It
is recommended to use a separate compressed air
hose only for working with the tyre inflator, because
there may be oil residues on other compressed air
hoses.
• Useing of the Compressed-air gun + suction-feed
can
– The compressed air spray gun operates on the
suction principle. Therefore the material container
is not under pressure. The compressed air, which
delivers the spraying material, is connected to the
air inlet and is lead through the gun body. The air
passes the nozzle when pressing the trigger. An un­
derpressure is generated by the high air flow speed.
As a result, the spraying material is drawn and de­
livered through the spraying tube and atomised at
the same time.

8. Operation

• Paint spray gun with gravity-feed can
1. Before starting to work, check the trigger (1c) to
make sure it moves freely.
2. Connect the paint spray gun to the compressed air
supply. The air should be regulated and filtered.
Setup the air pressure according to the parameters
supplied with the paint to be processed.
3. Note the parameters given by the manufacturer of
the coating materials to be used. Pour the material
to be processed in the paint container (1d) and care­
fully close the container with the lid. Pay attention to
the air hose when painting. Hold the hose firmly with
one hand while operating the paint spray gun with
the other hand. The hose must not be bent. Do not
step on it, as this will lead to formation of droplets.
4. Press the trigger (1c) and perform test runs on some
test pieces. This way you can determine the opti­
mum amount of paint and the different paint jet ad­
justments.
– The movement speed of the spray gun depends
on the setting of the paint flow regulator (1b).
With little paint, move the spray gun slowly. With
plenty of paint move it faster. Do not spray in an
arc on the surface and do not interrupt spraying
as this will lead to uneven or too little paint dis­
tribution onto the surface. The general recom­
mended spraying distance is about 15 – 20 cm.

– If the finish is too dry, use the flow regulator (1e) to
reduce the air supply. Turn the air regulator step­
lessly clockwise to reduce the max. possible air
pressure.
– If the finish is too wet, reduce the amount of paint
with the paint flow regulator (1b).
– If the atomisation is too coarse, increase the in­
take air pressure with the flow regulator (1e). If
the atomisation is too fine, reduce the intake air
pressure.
– Always keep the spray gun in a constant distance
to the surface to be sprayed.
– Always keep the hole on the lid of the paint con­
tainer open to avoid malfunctions.

allel lanes from one side to the other.
If necessary, take a short break after each spray­
ing process, so the paint may evaporate. Each lane
should overlap to at least 50%. Move the gun evenly

from top to bottom. Move the spray gun over the
edges of the object so that the edges get enough
