NO ABRASIVE FLOW WHEN BLASTING (AIR ONLY)
Possible Causes:
1. The Abrasive Blaster is empty or has no Abrasive in it.
2. The Metering Valve is closed or has not been adjusted
properly.
3. There is an obstruction in the Metering Valve.
To clear the
obstruction, perform the following procedure:
Open the Metering Valve to its fully open position. Depress the
control handle and have a second qualified person close the choke
valve for 2 seconds, and then open it again immediately. This will
push minor obstructions such as a small amount of wet abrasive,
a piece of paper from a bag, or bridged paint chips through the
Metering Valve and out the Nozzle. Readjust the Metering Valve
back to the desired setting for blasting, and check to see if the
obstruction has been cleared.
If there is still an obstruction, depressurize the Abrasive Blaster.
Completely remove the Metering Valve. The remaining abrasive
in the pressure vessel should pour out in a steady stream. If you
do not see a steady stream of abrasive, then there is a large
obstruction such as a large piece of paper from a bag of abrasive.
If you have determined there is a large obstruction, then the
obstruction must be removed from inside the Pressure Vessel. To do
this, make sure the Abrasive Blaster is depressurized and remove
the Handway Assembly. Scoop or vacuum out all the abrasive from
inside the pressure vessel and remove the obstruction. Reinstall
the Handway Assembly and Metering Valve and tighten them
securely, then Refill the Abrasive Blaster.
It is recommended that a screen be used to prevent foreign
objects from entering the Abrasive Blaster and causing an
obstruction.
4. The Abrasive Blaster has wet abrasive in it.
The wet abrasive
must be removed by depressurizing the Abrasive Blaster, removing
the Handway Assembly, and scooping or vacuuming it out.
Dry abrasive must always be used. Clean, cool, dry air must
be supplied to the Abrasive Blaster in order to prevent the
abrasive from getting wet. For Abrasive Blasters being used
outside, it is recommended that a lid be used to keep water
from entering the Abrasive Blaster.
ABRASIVE STREAM IS TOO HEAVY OR
THROBBING WHEN BLASTING
Possible Causes:
Note: CPR Systems may throb temporarily when starting up if
abrasive has collected in blast hose from previous use. This is
normal and requires no action to correct.
1. Choke Valve is partially closed
. Never run the Abrasive Blaster
with the Choke Valve in any other position except fully open or
damage to the Abrasive Blaster will occur.
2. The Metering Valve needs to be adjusted.
LOW PRESSURE AT THE NOZZLE
Possible Causes:
1. Air compressor is the wrong size (too small) or the load
button has not been pushed or turned on. (100 PSI Minimum)
2. Nozzle is worn out and the compressor cannot keep up with
the increased demand.
3. Air supply hose to the blast machine is too small.
4. There is a hole in the blast hose.
5. Control hoses and/or fittings are leaking.
6. Pop-up is not sealing properly.
7. Handway Assembly is leaking.
8. Choke Valve is partially closed.
Never run the Abrasive Blaster
with the Choke Valve in any other position except fully open or
damage to the Abrasive Blaster will occur.
9. Abrasive Metering Valve is open too far.
10. Obstruction in Nozzle.
11. Regulator needs adjustment (if equipped).
12. Inlet Valve/Diaphragm Valve is not opening/closing fully
due to inadequate control pressure.
13. Inlet Valve is damaged, defective, worn out, or not
lubricated properly causing it to not open fully.
14. Diaphragm Valve is damaged, defective, or worn out.
ABRASIVE BLASTER WILL NOT TURN ON OR
IS SLOW TO TURN ON
Possible Causes:
1. Air compressor is the wrong size (too small) or the load
button has not been pushed or turned on. (100 PSI Minimum)
2. Inlet Valve Petcock is open.
3. Nozzle is worn out and the compressor cannot keep up with
the increased demand.
4. Air supply hose to the blast machine is too small.
5. Inlet Valve is damaged, defective, worn out, or not lubricated
properly causing it to not open fully.
6. Diaphragm Valve is damaged, defective, or worn out causing
it to not close fully.
7. Control hoses and/or fittings are leaking.
8. Obstruction in Nozzle.
9. The Pneumatic Control Handle is damaged, defective or
worn out (if equipped).
10. The Electric Control Handle is damaged, defective or worn
out (if equipped).
11. Power Source (battery or AC-DC converter) is not providing
sufficient power to open electric control valves (if equipped).
12. The Electric Control Cord is damaged, defective or worn
out (if equipped).
13. The Electric Control Valve is damaged, defective or worn
out (if equipped).
14. There is an obstruction in the 1/16” orifice (See Valve Parts
Lists - PN 101-9450) (pneumatic controls only)
DANGER
: Never attempt to open the Abrasive Blaster in any way while it is pressurized. Use extreme
caution when performing troubleshooting procedures that involve pressurizing the Abrasive Blaster.
Troubleshooting procedures are to be performed by experienced qualified personnel only.
