unit/air dryer in the system. It could also be that there is too much debris in the grit, this can
be solved by filtering/replacing the grit.

When the spray is often disrupted, place a thumb (WITH GLOVES ON) over the nozzle and
(press firmly) and depress the foot pedal for a few seconds. Now the air blows back into the
suction hose, which can dissolve possible obstructions.
4.
Regularly check for leakages/obstructions in the compressed air supply. Adjust the pressure
to 5.5 bar on the air regulator, now press the foot pedal and check for sudden pressure drop.
If this is the case it means the compressed air supply is obstructed, this can be caused by:
-
Diameter of air hose too small
-
Blocked coupler/pressure regulator
-
Blocked/kinked hose
-
Distance between compressed air supply and sandblasting cabinet is too big
ADVICE: The diameter of the air hose should be at least ½ “.

In case of poor visbillity inside the cabinet by excessive dust, this could have the following
causes:
-
Air inlet top left of the pressure regulator is blocked
-
Dust exctractor is full and is to be cleaned/emptied
-
Filter of dust extractor is full/polluted by moist/oil
-
Grit is no longer good (too fine)
6.
Poor visibility inside the cabinet can also be caused by damaged protective foil, which is
placed over the viewing glass. This can easily be replaced by new foil. When the glass itself is
damaged, replace it by safety glass with the same thickness and measurements, you can get
this at your Zionair retailer.
Cleaning the dust extractor
Check the dust extractor after every 5 hours, remove dust by means of compressed air or vacuum
cleaner and removed clogged debris to ensure a proper functioning of the extractor.
