OPERATION
PRE-OPERATION STEPS AND CONNECTING AIR SUPPLY
Once the appropriate nozzle is installed and your abrasive is loaded in the tank,
you are now ready to connect the air supply hose to the air inlet and start
sandblasting.
First make sure the air supply valve (A) Fig.9 and the blast hose air supply valve
(B) are in the closed position (horizontal).
Also make sure the abrasive valve (A) Fig.10 is closed position (horizontal).
Connect the air supply hose from your compressor to the air inlet (C) Fig.9. Turn
the compressor on and adjust its air pressure regulator between 65-120 PSI,
depending on your requirements.
Move the air supply valve (A) Fig.9 to the open position (vertical), then lift the lid
with handle (A) Fig.11 upwards to seal the tank closed so that the tank can
pressurize.
Note: If the tank relief valve (D) Fig.9 trips open and exhausts air, immediately turn
the compressor off and correct the over-pressurization problem with the
compressor. If the tank exceeds its rated pressure, it may explode, causing severe
injury or death.
Move the blast hose air supply valve (B) Fig.9 and the abrasive valve (A) Fig.10
to the open position (vertical).
Point the media gun at the workpiece and press on the gun lever (see Fig.7) to
begin sandblasting. Move the media gun in a slow circular motion, try to keep the
media gun about 4” away from the workpiece. It will be necessary to experiment
with different pressures, abrasives and ceramic nozzles to gain practical
experience.
WHEN THE SANDBLASTING OPERATION IS OVER
When the sandblasting operation is over, always close the air supply valve (A)
Fig.9 before you disconnect the air supply line (C), or else the residual air will
expel sand backwards through the water saparator filter and out the air inlet,
damaging the water separator filter.
Be carefull when disconnecting the air supply hose, there is still a high amount of
pressurized air in the system. Once the air supply hose is removed, the small
bleed valve on the air supply valve will release air from the tank, once the air
pressure goes below 60 PSI, open the air supply valve to quickly release the
remaining air pressure in the tank.
MAINTENANCE INSPECTION
Check the following items each time you use the sandblaster and replace any
parts immediately if they are worn or damaged:
• Look for excessively worn or cracked ceramic nozzles.
• Look for leaking thread fittings with soapy water or a spray bottle.
• Look at the sand blasting hose for thin walls or bubbling.
• Look for worn or leaking valves with soapy water or a spray bottle.
