6. Operation
Warning!
Follow the safety precautions provided by the
manufacturer of the material you want to spray.
Use suitable face masks, gloves and protective
clothing.
6.1 Material preparation
The paint usually has to be thinned before it can
be used in the spray gun. Instructions on how to
thin the paint for spraying are not always printed
on the paint tin. You should use the viscosity table
as a guide (viscosity = consistency of the paint).
6.1.1 Measuring the viscosity (Fig. 7)
1. Mix the material thoroughly before measuring.
2. Completely immerse the viscosity cup (8) into
the material.
3. Then lift the viscosity cup (8) out of the mix-
ture and use a stopwatch to measure the time
it takes for all of the material to fl ow through
the cup. As soon as the continuous fl ow out
of the bottom is interrupted, stop the timer.
Repeat until you have the viscosity you need.
This is the „Draining time in seconds". (See 10.
Viscosity Table)
6.1.2 Nozzle diameter
The size of the nozzle and the fl uid needle to be
used depends on the viscosity of the material.
Depending on the viscosity, use the 3.0 mm dia.
nozzle (colour: white, for high viscosity), or the 2.5
mm dia. nozzle (colour: black, for medium viscosi-
ty), or the 1.5 mm dia. nozzle (colour: grey, for low
viscosity). The fl uid needle in the tool is suitable
for all three nozzle diameters.
6.2 Working with the paint spray gun (Fig. 8)
Important! Cover all surfaces which must be
protected from the spray, even areas which are
further away from the place where you are wor-
king. A fi ne mist from the spray gun can spread
to areas in the wider surroundings indoors and
outdoors, and the material will be deposited on
surfaces there.
•
Unscrew the container (12) from the paint
spray gun.
•
Align the material tube (11) for the object you
are working on.
•
Spaying on horizontal objects: Rotate the ma-
terial tube (11) towards the front.
•
Spaying on raised objects: Rotate the materi-

al tube (11) towards the rear.
•
Never continue spraying until the container
is completely empty. If the material tube no
longer reaches the spray material, the spray
flow will be interrupted and the coverage on
the surface will be uneven.
•
Once you have performed the viscosity mea-
surement as described in 6.1.1, place the
container (12) on some paper, pour in the
material you have prepared and tightly screw
the container (12) back into the paint spray
gun.
•
The paint spray gun is allowed to be placed
only on a clean, even surface. Otherwise it
might tip over.
•
After each cleaning (see 6.6) or change of fan
pattern (see 6.3), tighten the air cap retaining
ring (1) to prevent material from leaking out
between the air cap retaining ring and the air
cap (2).
6.3 Adjusting the fan pattern (Fig. 9, 10)
You can set the paint spray gun to produce three
diff erent fan patterns to suit your needs.
Loosen the air cap retaining ring (1) and rotate
the air cap (2) to the desired position. Re-tighten
the air cap retaining ring.
Selecting the fan pattern:
A: vertical fan
-> for horizontal surfaces
B: horizontal fan
-> for vertical surfaces
C: Round cone
-> for corners, edges and surfaces that are dif-
fi cult to access
Selecting the air volume
Flat fan: Push the control lever (7) downwards to
reduce the air volume > The fl at fan will become
narrower and fi nally dot-shaped.
Solid cone: Push the control lever (7) downwards
to reduce the air volume > The solid cone will
become wider.
Risk of injury!
Never press the trigger while you are adjusting
the jet.
6.4 Adjusting the material fl ow (Fig. 11)
You can rotate the max. paint volume control (6)
to regulate the material fl ow.
