3 Preparation
1. Place the blast system near 115V/60Hz (240V/50Hz) AC electrical outlet. Make sure the receptacle will accept the
3-prong plug, so that the unit will be properly grounded. Also make sure to check the power source is adequate for
use with this blast system. An electrician should be consulted if the proper outlet is not available or if the user in any
way questions the condition of the electrical circuit (see "Safety").
2. Attach the air supply line from a compressor capable of maintaining 5 cfm at 80 psi (5,51 bar) to the inlet
connection found on the right side of the cabinet. Because the variation in air supply systems, the air inlet coupling is
not provided. Use the particular fitting that is compatible with your air supply system.
Do not operate the blasting system at over 100 psi (6,89 bar).
3. Check the air supply line fittings and hose attachments to the rear of the gun. Also make sure the media supply hose
is attached tightly on the nipple on the underside of the gun.
4. Place not more than 10 pounds (5 kg) of abrasive media into the center of the cabinet. Excessive amounts will create
clouded cabinet conditions, blow by of media through the exhaust, or sluggish and ineffective blasting performance.
5. With the air supply connected, all fittings and joints not leaking and the unit is plugged in, you are ready to test the
blasting system.
4 Use
1. Place the part in the cabinet. Always close and latch the lid after placing the part in the cabinet prior to blasting.
Severe injury to the skin and eyes may result from exposure to the blast stream.
2. After putting your hands into the gloves, grasp the gun and depress the trigger. This should begin the blasting flow. If
no flow is seen, you may need to clear the tube by covering the gun nozzle momentarily.
3. Now you may begin finishing the part. You should move the blast stream continuously over the part in an even and
circular motion. The flow should not be too hard or concentrated to avoid undesirable peeling.
5 Maintenance
Note: Disconnect power and air before any maintenance!
All blasting system is prone to plugging or wear because of the abrasive material used and the applications. The
following items should be checked for wear as indicated:
Plugged conditions
The blast nozzle may become plugged from moist media. Try dislodging the media with a drill bit held in your hand. You
need to get rid of the moist media.
If the abrasive pick-up hose appears plugged, cover the gun tip and force the air back through this hose. Dust may fly up
when you do this so make sure the lid is down!
Wear conditions
This is usually noted when an excessive amount of dust appears in the cabinet. Dust will occur if:
1. The abrasive blasting media is worn out. If it has lost its granular or spherical appearance or has a lot of debris
from the parts being blasted and mixed in, replace it. This is usually noticed when the abrasive media that exists the
nozzle looks like a smoke cloud coming instead of a stream.
2. The air outlet vent is plugged or air flow out is blocked. Cleaning this vent should help reduce dust in the cabinet.
This gun parts may wear out. This is usually evident when the blast pattern is too wide and ineffective, simply replace
nozzle or orifice.
To replace the transparent pvc board
At the bottom of parts n° 1 transparent top lid, there is a 0.5 mm replaceable transparent pvc board. When at work, if
the transparent pvc board is getting unclear, it may be replaced with a new one to avoid affecting the sight during work.
