D. Adjusting the cleaning intensity:
Adjust the sandblasting intensity as appropriate, depending on the type of the object to be
cleaned. For solid, thick-walled objects, the pressure may be near the maximum (0.8MPa).
For objects with an openwork structure, it is recommended to lower the pressure to 0.6MPa.
If, despite lowering the pressure, the object becomes damaged, select a lower pressure
value empirically, as appropriate.
In order to adjust the cleaning intensity, unlock the regulating device by pulling the knob, and
use the readings of the pressure indicator to select an appropriate value. After performing the
adjustment, lock the regulating device by pushing the knob.
4. Usage:
Before supplying the sandblaster with air, follow the instructions below.
1. Place the sandblaster in the intended working place.
2. Connect the air supply (max. 115 psi) to the connector on the sandblaster side.
3. Check the integrity of all conduits. If there is any leakage, it must be repaired or
sealed with Teflon tape.
4. Connect the 12V power supply to the power socket. Check that the LED is working.

5. Stick the PE sheeting onto the inner surface of the glass. By default, the sheeting is
already affixed in the sandblaster.
6. Pour the box of the abrasive material provided into the sandblaster. When
replacing/replenishing the abrasive material, pour no more than 4.53kg. Too much
abrasive material will cause ineffective operation. When pouring the abrasive material
into the sandblaster, wear safety goggles.
7. Carefully close the sandblaster cover.
8. Put your hands into the protective gloves, place the object to be cleaned below the
nozzle
and begin cleaning by pressing the foot control.
9. Perform sandblasting with a continuous stream of air, moving the object in circular
motion.
10. In order to empty the sandblaster, remove the plastic plug from the bottom of the
device.
5. Maintenance:
Before performing maintenance of the device, disconnect the power and the air.
Clean the cover and parts of the sandblaster with soft cloth. Do not use solvents for
cleaning.
Avoid allowing moisture into the abrasive material, as it may cause clogging of the nozzle.
Attempt to remove such clogging with a drill.
6. Safety Information:
The sandblaster may create a powerful stream of abrasive particles. In order to avoid bodily
injury and/or property damage, carefully read the instruction manual before assembling,
operating or performing maintenance of the sandblaster.
 CAUTION !
1. During operation, do not expose your skin or hands directly to the line of operation of
the sandblaster nozzle.
2. Check that all components of the sandblaster are properly sealed.
3. Do not exceed the maximum operating pressure of the sandblaster.
4. Before replacing the accessories or beginning the assembly, repair, transport, or any
form of maintenance, disconnect the sandblaster from the air container.
5. Check the quality of all hoses and pneumatic conduits before each use. Check that
all connections are secured.
6. Do not direct the nozzle at people or objects.

After each use of the sandblaster, wash your hands.
During the blowing and cleaning of printouts, dust may form.
Protect your eyes and airway. Wear protective clothing.
Fire and explosion hazard! Do not use the sandblaster
around flammable liquids, dusts, gases and other materials
that are flammable or may explode. Some abrasives may
create sparks upon contact with metal. Abrasive material
similar to aluminium oxide may generate sparks that will
cause fire or explosion in a hazardous environment.
Electrocution may be painful. Wear leather or rubber soles
or shoes and stand on the ground to avoid electrocution. An
earthed wire attached to the sandblaster gun will safely
remove electrostatic charges.
