Operation - Scheppach 3906101704 Originalbetriebsanleitung

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 sec-
onds.
• 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 neces-
sary.
Using of 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, recommended
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 man-
ual 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.
Using 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
underpressure is generated by the high air flow
speed. As a result, the spraying material is drawn
and delivered through the spraying tube and atom-
ised 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 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 distribution onto the surface. The general
recommended 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
steplessly clockwise to reduce the max. possi-
ble 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 dis-
tance to the surface to be sprayed.
• Always keep the hole on the lid of the paint con-
tainer open to avoid malfunctions.
5. Hold the spray gun vertically to the surface to be
sprayed and move the spray gun evenly and in
parallel lanes from one side to the other.
6. Start spraying openings and corners of the object.
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 and always horizontal to the object.
Always work from top to bottom. Move the spray
gun over the edges of the object so that the edges
get enough paint.
