10.3 Filling with blasting media (Fig. 9)
1.
Put on your personal protective equipment, i.e.
respirator, safety goggles and gloves.
2.
Ensure that the blasting media is not damp. Check
that the blasting material has the correct grain size
of 0.15 - 0.25 mm and that the supply lines are not
blocked.
3.
Close the main supply line shut-off valve (18) on
the air supply line and make sure that the pressure
vessel internal pressure gauge (1) is at 0 bar.
4.
Close the blasting media shut-off valve (12).
5.
Slowly open the seal (4) by turning anti-clockwise.
NOTE: If you notice air escaping when opening
the seal (4), wait until the pressure is completely
released before opening the seal (4) completely.
6.
Fill the pressure vessel (5) with blasting media,
with the help of a funnel (A). Note the max. filling
capacity of 42 litres.
7.
Remove the funnel (A) again and close the pres-
sure vessel (5) with the seal (4) by turning it clock-
wise.
10.4 Compressor requirements
1.
The right compressor for sandblasting should
meet the following requirements:
• A pressure vessel of at least 100 litres capacity.
• A delivery rate of at least 170 litres/min.
NOTE!
• What is important here is the output power and
not the intake power of the compressor.
• Also note that the output of the compressor
changes as the pressure increases.
2.
It is recommended to use a pressure of 4.1 - 8.6
bar on the sandblaster to achieve the best results.
10.5 Connecting to the compressed air (Fig. 10)
1.
Before connecting the compressed air line, make
sure that the main supply line shut-off valve (18)
is closed.
2.
Connect the compressed air hose (not included in
the scope of delivery) to the compressed air con-
nection (19).

10.6 Working with the product (Fig. 1, 10, 11)
m WARNING!
Danger of injury! Make sure that other persons main-
tain a sufficient safety distance.
1.
Connect the compressed air hose to the com-
pressed air connection (19) and set the preferred
operating pressure on the compressor. It is recom-
mended to use a pressure of 4.1 - 8.6 bar on the
sandblaster to achieve the best results.
2.
Slowly open the main supply line shut-off valve
(18).
4
Then open the blasting hose supply line shut-off
valve (16).
5.
Now slowly open the blasting material shut-off
valve (12) until blasting material comes out of the
blasting gun (8). This regulates the amount of sand
that reaches the blasting gun (8) from the pres-
sure tank (5). The best sandblasting results are
achieved when the blasting material shut-off valve
is opened to approx. 1/3.
6.
Hold the blasting gun (8) firmly, point it at the sur-
face to be worked on and press the lever (6). When
you release the lever (6), the supply of blasting ma-
terial must be completely stopped.
7.
Clean the surface to be worked on by moving the
blasting gun (8) slowly and evenly.
8.
After the work process, first close the blasting ma-
terial shut-off valve (12) so that no blasting material
remains in the lines.
9.
Close the main supply line shut-off valve (18).
10. Switch the compressor off.
11. Keep the lever (6) on the blasting gun (8) pressed
until all the air has escaped from the lines.
12. Close the blasting hose supply line shut-off valve
(16).
13. It is recommended to empty all of the blasting
material out of the container after work to avoid
clumping due to humidity.
10.7 Work hints and tips
When sandblasting, there are some important points
that should be considered:
• Always wear protective clothing. Sandblasting
can release small sand particles and dust that can
irritate the eyes, skin and respiratory organs. It is im-
portant to wear protective clothing such as gloves,
goggles and a respirator.
• Prepare the surface: Before sandblasting, the sur-
face should be thoroughly cleaned to remove dirt,
grease and rust. This ensures an even blasting force.
