7. Before first use

Connect:
Push the nipple on your compressed air hose into the
quick-release coupling, the sleeve will automatically
spring forwards.
Disconnect:
Pull back the sleeve and remove the hose.
m WARNING
As you release the hose coupling, hold the hose cou­
pling part in your hand to prevent injuries caused by
the hose being thrown backwards.
The compressed air hose is also fitted with a quick­
lock coupling to which accessories can be connected
as described above.
• Using of the Compressed-air hose
– Use the air spiral hose to connect the com­
pressed air tool with the compressed air supply.
– Connect the quick coupling connector (5b) with
the air supply and connect the air tool connection
(5a) with the compressed air tool.
• Using the Paint spray gun with gravity-feed can
­ Preparing the Surface to be painted
The object to be painted, or the surface, etc. has
to be clean, dry and free of grease and dust.
Metal surfaces must be stainless. Since the fine
sprayed paint is dispersed in a very thin layer on
the surface, roughness would have a negative ef­
fect on the paint result.
­ Viscosity testing
Viscosity is the flow rate of a material. Measure
the viscosity with a viscosity cup (not included)
as follows:
1. Thin the paint according to the manufacturer's
recommendation. Start with less thinner so you
still can and add some thinner later.
2. Mix the paint thoroughly. Pour the paint into the
viscosity cup or dip the cup to the edge into
the paint.
3. Measure the time in seconds until the liquid
thread breaks off. This flow time is called DIN-s.
Thin the material as much as necessary until the
liquid thread already breaks off after 20 seconds.
Paint Jet Adjustment
– For a wide jet (horizontally), align the nozzle
(1a) vertically.
– For a high jet (vertically), align the nozzle (1a)
horizontally. Use this setting for spraying larger
areas.
– Use flat-nose pliers to adjust the nozzle if nec­
essary.

• Using the tire pressure gauge
m Note
– The optimum air pressure of the car tyre not
only provides safe performance and durability of
your tyres – using the right tyre pressure, rec­
ommended by the automobile manufacturer, also
can safe fuel.
– You will find the details on the comfortable mini­
mum 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, be­
cause there may be oil residues on other com­
pressed air hoses.
• Using the compressed-air gun + suction-feed
can
– The compressed air spray gun operates on the
suction principle. Therefore the material con­
tainer is not under pressure. The compressed
air, which delivers the spraying material, is con­
nected to the air inlet and is lead through the gun
body. The air passes the nozzle when pressing
the trigger. An underpressure is generated by the
high air flow speed. As a result, the spraying ma­
terial is drawn and delivered 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 fil­
tered. Setup the air pressure according to the pa­
rameters supplied with the paint to be processed.
3. Note the parameters given by the manufacturer
of the coating materials to be used. Pour the ma­
terial to be processed in the paint container (1d)
and carefully 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 optimum amount of paint and the different
paint jet adjustments.
– The movement speed of the spray gun de­
pends on the setting of the paint flow regula­
tor (1b). With little paint, move the spray gun
slowly. With plenty of paint move it faster.
