technical problems please contact our Customer Services.
Assembly
1. Attach one end of theair hose to thepressure source (compressor or aerosol can)
and theother to theairbrush.
2. Theair pressure should lie between 1–3.5 bar. Normal working pressure is 2 bar.
We recommend using apressure regulator with water separator in order to avoid
moisture problems. For large jobs, anair compressor with atank is recommended.
Theincluded adapter enables you to connect thehose to a1/4″air outlet coupling.
3. Pour thepaint into thepaint reservoir. Thepaint should be relatively thin, about half
thethickness of paint used for brushing (see Mixing colours further on in thetext).
Attach thepaint reservoir to corresponding hole on theairbrush. Hold theairbrush
perpendicular to thework surface.
4. Press down thetrigger lever and pull back until it sprays. Use alower air pressure
when spraying close to asurface. Thecloser you spray thenarrower thestream.
Theairbrush is pre-adjusted from thefactory to provide anarrow stream.
How to spray
Thebest result is obtained when sweeping theairbrush along at aneven speed.
Commence thesweep before pressing thetrigger lever and continue movement
even after releasing thetrigger lever.

Exercise 1
• Spray dots on paper or cardboard. Hold theairbrush tip about 12 mm from
thesurface (Figure 1). Use thinned ink or water soluble paint. When you are
satisfied with theresult make larger circles (more paint and greater distance).
• Holding theairbrush too close and pulling thetrigger lever all theway back will
result in small blotches of paint (Fig. 3 and 4). Work carefully and take your time.
Practice until you achieve proper circles with thedesired size.
This simple exercise will improve your aim and help you achieve theright paint
thickness. This is especially important when retouching or filling.
Fig. 1 Fig. 2 Fig. 3 Fig. 4
Exercise 2 – Freehand effects
The exercise shown in Figure 5 will teach you to spray straight lines without blotches
and spots.
Figure 6 shows straight, widening lines. To achieve this, increase thepaint as you pull
theairbrush back away from thework surface.
Practice daily to improve your feel and
precision.
Figure 7. Draw small squares with apencil. Spray dots as small as possible on thelines.
Join thedots with fine, same-thickness lines.
Fig. 5 Fig. 6 Fig. 7
Common problems:
Drops and blotches due to:
1. Spray being stopped too early or finger lever released too late.
2. Airbrush being swept along too slowly.
3. Airbrush being held too close to work surface.

Masking
Use asquare template for thefollowing exercises.
Wrap thetemplate with paper and tape it down.
Do not spray beyond themasking tape.
Exercise 3 – How to achieve an even hue
To achieve aneven hue, begin with anarrow spray at theupper left and sweep to
theright. Keep adistance of 10 cm and spray slightly beyond themasking tape to
achieve asharp border. Now spray from right to left and let thespray overlap
previous sweep. Spray theentire surface in this manner.
Fig. 9 Fig. 10 Fig. 11
Exercise 4 – How to shade
This exercise is similar to theprevious one. Begin from below and enter thewhite
surface. Do not spray more than between 2/3 to 3/4 of thesurface. Hold theairbrush
tip further away for each new sweep. Keep in mind that thepaint becomes thicker for
each coat. Figure 13 shows acombination of masking and shading. Training theeye is
important in order to be able to achieve consistent shading for all thesquares.
Theeffect in Figure 14 is achieved by using around mask and by spraying towards
and beyond themasked boundaries thus accumulating most of thepaint on themask.

Exercise 5 – Three-dimensional effects
By practising with these basic shapes you can learn how and in what order to shade.
These shapes and their combinations cover everything you will ever come across.
In this exercise, imagine that thelight is always approaching from theupper left at
a45° angle. Make thefigures about twice as large as those in theimage.
Cubes
Draw acube on thepaper twice thesize as theone below. Cut amask for each
edge and tape it down. Now remove themask at theedge furthest from thelight
source. Shade (as in Exercise4) from theupper left down toward thelower right.
Spray another coat as needed. Now re-mask thefinished side and do thesame for
theother sides until you have achieved thedesired result.
Cylinder
First, study how thelight varies on thecylinder surface and how theflat surface
on top contrasts with thecurved surface. Form themask to match thecurved
line. Cover thetop first and shade thecylinder. Now cover thecylinder and shade
thetop. To obtain thesame hue on both surfaces requires much practise.
Cones
Begin by cutting amask in theform of acone. Start shading from above and
sweep towards thebase of thecone. Do thesame for theother side of thecone
until you have achieved thethree-dimensional effect shown in thefigure.
Spheres
Cut a disc out of the masking material and use thematerial with ahole in it as
ashading mask and thedisc as amask. Now shade thework surface until thesphere
appears three-dimensionally.
Note: Do not apply too much paint. Spray preferably athin layer first and let dry.
Then spray another layer, and so on. This takes time but is worth it.

Technique, 3-dimensional
Cover up those areas of thework surface that you
want to preserve. Thework surface must be free from
grease, dust and dirt. Small objects are best sprayed
hanging or set on asurface that allows you to spray
from all sides. Bottles, wire and other such aids may be used.
Hold theairbrush tip about 15 cm from thework surface. Apply short sprays
and sweep theairbrush at aneven speed at aneven distance from thesurface.
Do not apply thepaint too thick. Spray preferably athin layer first and let dry.
Then spray another layer, and so on. This takes time but is worth it.
Mixing colours
To achieve adesired hue you must mix different colours together. Keep in mind
thepaints that you mix must be of thesame type, for example mix enamel only with
enamel, lacquer only with lacquer and so forth. Mix them well and long. Filter thepaint
if lumps arise.
Thinning
Most store bought paints are too thick to airbrush. Thin your enamel paint or lacquer to
a1:1 ratio. Follow themanufacturer’s recommendations when thinning automotive lacquer.
Cleaning and care
This airbrush is aprecision instrument for professionals and enthusiasts. Always clean
theairbrush and paint reservoirs thoroughly. Remove paint or other deposits from
theairbrush directly after use or thenarrow channels will clog and you will not be able
to clear them again. Cleanliness is actually themost important point we can make
and it cannot be stressed enough. Most functional problems arise due to insufficient
cleaning of theairbrush.
After taking out theneedle from theairbrush for cleaning (always use appropriate
solvent), it should be put back very carefully and without excessive force. Spots and
deposits may be removed with asoft eraser while resting theneedle on aflat surface.
Theneedle itself is delicate and should not be bent in any way since this would render
theneedle worthless. Tighten thelocking screw firmly when reinserting theneedle.
Always protect theneedle tip.

Common problems
1. Grainy paint. This happens when thepaint is too thick. Carefully thin thepaint.
Make sure theneedle and adjustment screw are free from dried paint. Also check
theair pressure.
2. Bubbles arise on thepaper. Thepaint is probably too thin. Do not spray too long
over thesame spot. Move theairbrush faster or weaken thestream.
3. Blotches at theend of thesweep. Begin spraying before beginning thesweep and end
thesweep before stopping thespray.
4. Flared ends. Caused by turning thewrist while sweeping. Your entire arm must
sweep horizontally across thepaper.
5. Spidery splashes. You are spraying too much and too close. When you want to
spray fine lines, pull thelever back only slightly.
6. Splashing. This happens when theneedle slides too quickly into thenozzle. Always
operate thenozzle slowly, feeling your way forward. Make sure there is no dried paint
on theneedle or nozzle.
7. Curved line. This happens when making thesweep with your arm too close to thepaper.
Always hold your arm thesame distance from thework surface to avoid this.
8. No stream. Thenozzle may be tightened too much. Loosen 1–2 turns.
9. Bubbles in thepaint reservoir. Thenozzle may be open too much. Tighten it
somewhat. Another cause may be aclogged siphon.
10. Thestream will not shut off. Thenozzle may be clogged. This is evident when
theneedle feels spongy when moving it forward. Clean thenozzle carefully and
flush it with solvent (see Cleaning and care).
11. Theairbrush spits. This is caused by deposits on theneedle or in thepaint
reservoir. Alternatively, thepaint may be too thick.
Remarks from the manufacturer
Nozzle Needle
O-ring
AnO-ring on theback of thenozzle eliminates theneed
to wax thethread there. Normal wear, solvents or other
damage may eventually allow air to leak in thus resulting
in apulsating stream. Replace thepacking.
Disposal
Follow local ordinances when disposing of this product.
If you are unsure about how to dispose of this product contact your municipality.

Montering
1. Anslut slangens ena ände till tryckkällan (kompressor, aerosolburk) och den andra
till färgsprutan.
2. Lufttrycket bör ligga mellan 1–3,5 bar. Normalt arbetstryck är 2 bar. För att undvika
fuktproblem rekommenderar vi användning av tryckregulator med vattenavskiljare.
För större sprutningar rekommenderas kompressor med tank. Medföljande adapter
gör det möjligt att montera slangen till en 1/4″insticksnippel.
3. Häll ifärgen ifärgbehållare. Färgen bör vara relativt tunn, ungefär hälften så tjock
som vid strykning med pensel (se Blandning av färger längre fram). Sätt fast färg-
behållare i motsvarande hål på sprutan. Håll sprutan vinkelrätt mot arbetsytan.
4. Tryck ner utlösaren och dra bakåt tills strålen kommer. Använd lägre lufttryck vid
sprutning nära föremålet. Ju närmare man sprutar desto mindre strålbredd används.
Från fabriken är strålfördelaren inställd för att ge en smal stråle.
Hur man sprutar
Det bästa resultatet får man om man för sprutan med jämn hastighet. Börja med att
föra sprutan innan strålen kommer och fortsätt något även efter det att strålen slutat.
