If pressure is available remove and disassemble the Pinch Valve
assembly. Clean parts and replace any that are worn or damaged.
B. If both the Pinch Valves tubes stay open when the unit has air, and
the Abrasive Pinch Valve Solenoid Valve is working properly:
Disconnect the output hose from the Pinch Valve Regulator and check
for air pressure (approx. 40 psi/276 kPa). Readjust the Pinch Valve
Regulator if the air pressure is low or absent. If no adjustment is
possible, replace regulator.
If the regulator is functioning properly, test the Check Valve for proper
operation. Also check the air line fittings for possible blockage.
C. If either or both of the Pinch Valves fail to close properly:
Follow the check out procedure outlined above to be sure they are
getting correct air pressure at the air inlet and that the Abrasive Pinch
Valve Solenoid Valve is working properly.
If the correct pressure is being supplied to the Pinch Valve;
disassemble the Pinch Valve, clean the parts and replace any that are
worn or damaged.
3) PINCH VALVE REGULATOR ADJUSTMENT:
The Pinch Valve Regulator adjustment is factory set to supply the correct
air pressure to the pinch valve assemblies for normal operation.
Any decrease of pressure may create a leak through the nozzle tip. Too
much pressure will cause premature wear the pinch valve tube.
RECOMMENDATION: Leave this regulator at its factory setting. If
problems are experienced with the Pinch Valves, check the Pinch Valves,
solenoids and hoses for proper operation prior to readjusting the regulator.
C. LEAK DETECTION SYSTEM
The Red Leak Indicator Lamp will light when the rubber pinch tube in one of
the Pinch Valves or the powder/air hose between the Mixing Chamber and the
Abrasive Pinch Valve or Handpiece has a leak in it. After the tube or hose is
replaced, the Reset Switch must be depressed after the Power Switch is
turned on.
D. PINCH VALVE TUBE REPLACEMENT
The rubber pinch valve tube wears and will eventually leak. The Pinch Valve
is not removed from the unit for tube replacement.
