IMPORTANT!
• The Inner Air blow gun 20 has no pressure adjustment - it is used to sandblast larger surfaces
and elements.
9. Put your hands in the Protective rubber gloves 4 , grab the printout and start cleaning by pressing the Control
pedal T .
• When using the Inner Air Blow Gun: do the same, but instead of using the Control pedal, press the handle of
the Inner Air blow gun and start sandblasting.
10. Sandblast the printout with a continuous stream of air, moving the printout in circular motions until all unnecessary
powder is removed.
• Keep the Inner air blow gun 20
at an angle of 45-60 degree towards the work piece at a distance of 10-15 cm
with the nozzle pointing towards the backside of the sandblaster.
• Never hold the Inner Air Blow Gun in a 90 degrees toward the workpiece. This causes the grit to rebound back
into a spray, which causes a less effective spray. This also causes extra wear to the gun and PE protective foil
19
.
11. After cleaning the printout, wait a moment for the dust to fall down. Open the door and remove the sandblasted
object.
12. Close the door.
13. All remaining powder and abrasive material can be blown out of the printout with an external Air blow gun L .
14. After nishing work, turn off the pressure to 0 bar (0 psi) and turn off the sandblaster.
7. Maintenance of the Sinterit SANDBLASTER SLS
WARNING!
Before replacing the accessories or beginning the assembly, repair, transport, or
any form of maintenance, disconnect the Sinterit SANDBLASTER SLS from the
compressor, turn off the machine and unplug it from the power source.
Check before each use:
1. Check the sandblaster chamber 9 before every use for damaged and/or deformed parts.
2. Check all pneumatic tubings for wear and tear and check if the Static nozzle 19
and Inner air blow gun’s nozzle 20
are not too worn.
3. Check if the Air lter 11
works well, clean it if necessary if the door 10 closes properly (check the door gasket 7 ).
4. Clean the window (outside and inside) and the parts of the sandblaster with a soft cloth. Do not use any solvents
for cleaning!
5. Prevent moisture from getting into the Abrasive material as it may clog the nozzles.
6. In case of a malfunction/defect, do not use the sandblaster until it has been repaired.
7.1 Replacement of the Abrasive material
If the Abrasive material is clotting, that means there is moisture in the compressed air or there is moisture/oil in the
system. This leads to clogging and an uneven spray.
It could also be that there is too much debris in the Abrasive material. This can be solved by ltering/replacing it.
When the spray is often disrupted, place a thumb (WITH PROTECTIVE RUBBER GLOVES ON) over the Static Nozzle
20
and (press rmly) and depress the Control pedal K for a few seconds. Now the air blows back into the suction
pneumatic tubing, which can dissolve possible obstructions.
STOP!
The user is responsible for disposing of used Abrasive material in accordance with
applicable laws.
