SOLUTION
1. CLOSE CHEMICAL METERING VALVE.
2. ALLOW THE UNIT TO RUN FOR 2 MINUTES WITH THE VACUUM HOSE DISCONNECTED TO REMOVE MOISTURE AND SPRAY WD40 (OR EQUIVALENT) INTO
THE VACUUM LUBRICATION CUP. THIS WILL PREVENT CORROSION DUE TO MOISTURE.
3. SET THROTTLE TO IDLE POSITION AND OPEN FLOW SIMULATOR VALVE, ALLOWING THE WATER TEMPERATURE TO COOL DOWN.
4. TURN OFF IGNITION SWITCH.
5. DISCONNECT ALL HOSES AND TOOLS.
6. DRAIN WASTE TANK INTO AN APPROVED DISCHARGE POINT.
1. CONNECT WATER HOSES TO WATER INLET CONNECTIONS AND TURN ON WATER SUPPLY.
2. CONNECT CLEANING AND VACUUM HOSES TO THE DESIRED CLEANING TOOL AND CONSOLE.
3. WITH THROTTLE PUSHED IN TO IDLE POSITION, AND CHOKE PULLED OUT 1 INCH, TURN OVERRIDE/SOLUTION PUMP SWITCH COUNTER-CLOCKWISE
AND TURN IGNITION KEY TO START. RELEASE OVERRIDE/SOLUTION PUMP SWITCH AND PUSH CHOKE IN.
4. INCREASE ENGINE SPEED BY ROTATING THROTTLE COUNTER-CLOCKWISE ABOUT TWO TURNS.
5. INSERT CHEMICAL INLET AND PRIME TUBING INTO CHEMICAL CONTAINER.
6. TURN CHEMICAL PRIME VALVE TO PRIME AND ALLOW CHEMICAL TO CIRCULATE. AFTER ALL AIR BUBBLES HAVE BEEN REMOVED FROM THE CHEMICAL
TUBING, TURN THE VALVE TO THE OFF POSITION, OPEN THE CHEMICAL FLOW AND FLOW SIMULATOR VALVES. SET THE DESIRED CHEMICAL FLOW RATE WHILE
OBSERVING THE FLOW METER INDICATOR. FLOW SIMULATOR VALVE MUST BE IN THE OPEN POSITION TO SET CHEMICAL FLOW. WHEN DESIRED FLOW IS
REACHED, TURN FLOW SIMULATOR VALVE OFF.
7. FOR QUICK HEAT-UP, REFER TO OPERATING INSTRUCTIONS.
8. SET THROTTLE TO DESIRED OPERATING SPEED.
