18. If there are any leaks, use Wrench F or PVC protection tape Eto resolve the problem.
6. Sandblasting the printouts
ATTENTION!
• Before starting any job with Sinterit SANDBLASTER XL, always wear Protective
Glasses, Protective Dust mask, and optional gloves.
• You can use use the “PERSONAL PROTECTION” set included with Sinterit Lisa printers.
ATTENTION!
• It is strongly forbidden to start sandblasting when the sandblaster is not fully closed
(open door) or when LED light 18 is not on.
• Make sure the Power switch 1 is OFF-position before plugging in the machine.
• The Inner Air Blow Gun 20 and external Air Blow Gun D should always point away
from the operator to the workpiece.
IMPORTANT!
• Before you can start sandblasting make sure the printout is free of oil, water and
moisture.
• The Abrasive Material should be moist free. Moist grit clutters, which causes a bad
ow and clogging.
1. Turn on the compressor and the Sinterit SANDBLASTER XL.
2. Check all the pneumatic tubings and joints for leaks. If they appear, replace the element or seal it with PVC tape E
or Teon tape (not available in the set).
3. Open the sandblaster door 10 and insert the printout into the chamber 9.
4. Place the printout on the grid 24 under the Static Nozzle 19 .
5. Close the sandblaster door 10 rmly.
IMPORTANT!
• Use the Inner Air Blow Gun 20 only for large and strong prints.
• The Static Nozzle 19 is ideal for standard and fragile prints.
• By default, ceramic nozzle no. 5 is installed in the Inner Air Blow Gun. You can also choose
to use a larger or smaller ceramic nozzle (available in the Accessory box).
• Nozzles smaller than No. 5 do not work precisely with the Sinterit Abrasive material.
• A bigger size ceramic nozzle gets the job done faster because it can blast a larger surface,
this also causes a higher air consumption, make sure the compressor can handle it.
6. Use the Pneumatic pressure regulator 3 and the Pressure gauge 5 and set the work pressure of the compressed
air between 5 and 8.6 bar (58-125 psi). You can start with a working pressure of 4-5 bar, then most workpieces can
be blasted easily with this pressure.

14 | Sinterit SANDBLASTER XL User Manual
7. In order to adjust the cleaning
intensity in Static Nozzle 19 , unlock
the regulating device by pulling
the Pneumatic pressure regulator
3 and use the indications of the
Pressure gauge 5 to select an
appropriate value. After performing
the adjustment, lock the Pneumatic
pressure regulator by pressing the
knob (Image 7).

5
Image 7. Unblocking the pneumatic pressure regulator.
ATTENTION!
• The Inner Air Blow Gun 20 has no pressure adjustment - it is used to sandblast larger
surfaces and elements.
• Adjust the sandblasting intensity appropriately, depending on the type of object to be
cleaned.
• For solid, thick-walled objects, the pressure may be near the maximum, which is 8.6 bar (125 psi).
• For objects with openwork structure, it is recommended to lower the pressure to 5 bar (125 psi).
• If despite lowering the pressure, the object becomes damaged, select lower pressure value
empirically, as appropriate.
8. Put your hands in the Protective Rubber Gloves 6 , grab the printout and start cleaning by pressing the Control
pedal K .
• 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.
9. 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
25
.
10. After cleaning the printout, wait a moment for the dust to fall off. Open the door and remove the sandblasted
object.
11. Close the door.
12. All remaining powder and abrasive material can be blown out of the printout with an external Air blow gun D .
13. After nishing work, turn off the pressure to 0 bar (0 psi) and turn off the sandblaster.

7. Maintenance of the Sinterit SANDBLASTER XL
WARNING!
Before replacing the accessories or beginning the assembly, repair, transport, or
any form of maintenance, disconnect the Sinterit SANDBLASTER XL from the
compressor, turn off the machine and unplug it from the power source.
Check before each use:
1. Check the sandblaster chamber 9 previous to each 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 17 works well, clean it if necessary, nally, also check if the door 10 still close properly (check
the door gasket 11 ).
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. Avoid allowing moisture into the abrasive material, as it may cause clogging of the nozzles.
6. In case of a malfunction/defect, do not use the sandblaster until it has been repaired.
A. REPLACEMENT OF THE ABRASIVE MATERIAL
1. In case the Abrasive material is clotting, this means there is moisture in the compressed air or there is moisture/
oil in the system. This leads to clogging and an uneven spray.
2. It could also be that there is too much debris in the Abrasive material, this can be solved by ltering/replacing it.
3. When the spray is often disrupted, place a thumb (WITH PROTECTIVE RUBBER GLOVES ON) over the Static Nozzle
19
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.
EXCHANGE OF ABRASIVE MATERIAL WITH SINTERIT ATEX VACUUM CLEANER
To remove the used Abrasive material from the inside of the sandblaster we recommend using Sinterit ATEX Vacuum
