INTRODUCTION Thank you for selecting a quality Easy-Kleen product. We are pleased to have you included among the many satisfied owners of Easy-Kleen cleaning machines. Years of engineering have gone into the development of these fine products and only top quality components and materials are used throughout. Each machine is carefully tested and inspected before leaving our plant to ensure years of dependable performance.
OPERATING INSTRUCTIONS 1. Perform pre-start maintenance inspection on all applicable systems prior to operating the machine. This is essential for the safe, effective and efficient operation. You will get optimum performance from your system ONLY if these instructions and inspections are followed. Any indication that the pressure washing system was not operated and maintained according to these instructions may cancel the manufacturers’ warranty.
3. Attach water source to water inlet located on pump. The water source must be attached with a good quality standard garden type hose (1/2” minimum is required). Connect male fitting into the female pump inlet fitting. Make sure that the inlet screen/filter is intact and fitted correctly. Turn on water source. WATER MUST BE IN SUFFICIENT SUPPLY, AND PRESSURE MUST BE BETWEEN 20 –60 PSI TO ENSURE PROPER AND SAFE OPERATION. Specific attention should be given if using a well water supply.
the system. Any further turning of the unloader will cause the pressure to spike when the wand trigger is released, resulting in possible damage to the machine. To avoid this effect, loosen the unloader (counter-clockwise) until the pressure just starts to drop (see pump head pressure gauge) and until it no longer exceeds the maximum pressure rating for the machine. 7. You are now ready to start the cleaning operation - Pull trigger on the pressure wand assembly to start cleaning.
3. Fit black nozzle on the standard wand, or for the dual wand, turn adjustment knob on, and adjust for required flow rate. For high pressure soap systems, the black nozzle is not needed; use one of the other wand nozzles. 4. To apply chemical, engage trigger on pressure wand assembly. Turn chemical injector’s nipple to adjust flow. For the high pressure soap systems, open ball valve and engage trigger. 5. Chemical can now be applied through pressure wand assembly.
Final adjustments to burner include fuel pressure adjustment for controlling water temperature (tighten fuel pressure adjustment screw slightly to increase desired output temperature) and air band adjustment for combustion efficiency. A combustion test kit should be used for these final adjustments. Check SPECIFICATIONS chart (page 7) for the burner oil pressure corresponding to your model and be sure not to exceed this pressure.
MAINTENANCE CHECKLIST Maintenance for Pump Daily 1. Check oil for proper level and adjust accordingly. 2. Examine the quality of the oil. 3. Check pump for oil and/or water leaks. 4. Inspect and clean inlet filters. Weekly 1. Examine all fittings, components, hoses, connections, and nozzles for damages, loose parts, or leaks. – Replace accordingly— Recommendation for Oil Changes and Component Replacement 1.
Recommended Schedule for Oil Changes and Component Replacements 1. Change engine oil after first 5 hours and every 100 hours after the initial oil change. Use 10w-30 engine oil. 2. Replace Spark Plug every 100 hours. 3. Change air cleaner element every 100 hours. 4. Check fuel filters every 300 hours. 5. Change all other components on engine as needed.

If you have any technical questions please do not hesitate to call us at 1- 800-315-5533.
POWER SYSTEM DIAGNOSTICS - Gas Motor Not Starting PROBLEM Gas motor not starting Spark Plug - strong gas smell Fuel POSSIBLE CAUSE SOLUTION Check to see if proper fuel levels are maintained No ignition Check ignition by removing spark plug from cylinder. If electric start, try starting using the recoil starter. Electric Starter/Battery Fuse blown in key switch Recharge or replace battery. 18 amp engine, open key switch, replace 30 amp fuse Flooded Wait 5 minutes before attempting to restart.
FLUID SYSTEM DIAGNOSTICS - Flow and Pressure PROBLEM No Flow POSSIBLE CAUSE No power Trigger gun valve No water source Clogged spray nozzle Clogged inlet filter Float Valve stuck (optional) Faulty unloader valve Incorrect or no spray nozzle Low pressure, adequate flow Worn spray nozzle Debris in valves Lance on low pressure Unloader is not adjusted correctly Pressure gauge inaccurate Low pressure, low flow Pump packings bad Volume Improperly adjusted Discharge leaks Downstream chemical injector (Dema)
PROBLEM POSSIBLE CAUSE Improperly adjusted unloader Faulty unloader SOLUTION Nozzle must be properly sized for the rated flow and pressure. Reset unloader or pressure relief if nozzle size is changed. Check the pressure gauge using a properly calibrated pressure gauge on quick connects at the equipment outlet. Adjust to the proper pressure using pressure gauge. Check the unloader action. If it is not working properly, it may need repaired or replaced.
FLUID SYSTEM DIAGNOSTICS - Unloader PROBLEM POSSIBLE CAUSE Very low or no flow Unloader stuck in bypass Unloader will not unload Debris in unloader Sever leak on the outlet of unit Improper flow Unloader (flow) cycles with system under pressure Nozzle to small Nozzle clogged Improper unloader orifice Unloader orifice clogged Injector orifice clogged Other downstream restriction Pump not delivering the rated pressure High water supply pressure Unloader (flow) cycles with system in bypass No restrict
Unloader (pressure) produces low flow and normal pressure Unloader (flow) produces low flow & normal pressure Unloader (pressure) leaks from main spring or adjusting bolt Unloader (flow) pressure increases when trigger released Unloader (flow) leaks water around adjusting bolt Unloader adjusted too low If the unloader is diverting flow to bypass it may be adjusted too low, readjust as necessary.
FLUID SYSTEM DIAGNOSTICS - Leaking ANY LEAKS SHOULD BE REPAIRED ASAP TO PREVENT DAMAGE TO THE SYSTEM. PROBLEM From inlet From low pressure (inlet) line fittings POSSIBLE CAUSE Garden hose washer SOLUTION Ensure the washer is present and in good condition. Loose clamps or connections Low pressure line should be properly sealed on barb and tightly clamped.
FLUID SYSTEM DIAGNOSTICS - Trigger Gun/Spray Nozzle PROBLEM POSSIBLE CAUSE Broken piston rod in trigger gun No nozzle flow from nozzle when trigger depressed.
BOILER SYSTEM DIAGNOSTICS - Oil Burner Will Not Fire PROBLEM POSSIBLE CAUSE Not reaching rated pressure Not activating boiler controls flow Thermostat on low setting Thermostat set too low Burner no getting adequate fuel No or low fuel in tank Low fuel shut-off control activated.
PROBLEM Steady fuel flow at bleed valve but none in combustion chamber Boiler controls activating Solenoid valve energizing Air and fuel flow proper POSSIBLE CAUSE SOLUTION Remove the solenoid cover and place blade of an insulated screwdriver in the coil with the system operating in hot water mode. A good working solenoid will hold the screwdriver in the solenoid. If not it may need replaced. Oil pump may have debris, replace as necessary.
BOILER SYSTEM DIAGNOSTICS -Gas Burner Will Not Fire PROBLEM No arc at the ignition pilot assembly Ignition operating properly Boiler controls operating properly POSSIBLE CAUSE SOLUTION Spark gap incorrect Check the spark gap and reset if necessary. Check for air in the propane line. Ignition module bad Boiler controls malfunctioning Check the ignition module and replace if necessary. Check boiler controls for good operation and correct problems.
BOILER SYSTEM DIAGNOSTICS - Boiler Controls PROBLEM No voltage solenoid Solenoid coil does not energize Solenoid coil energizes POSSIBLE CAUSE SOLUTION Boiler control or electrical problem A multimeter can be used to check continuity through controls and pinpoint the problem areas. Bad connection to solenoid coil Electrical connections to solenoid valve coil should be tight and not corroded. Coil bad Check to see if fuel solenoid will energize when the proper voltage is applied.
BOILER SYSTEM DIAGNOSTICS - Flow Switch - Optional PROBLEM Reed switch activates when tested with external magnet Reed switch does not activate when tested with external magnet POSSIBLE CAUSE SOLUTION Magnet fouled and will not move If magnet does not move freely within its housing, remove debris to unstick it.
