| PROBLEM | CAUSE | CORRECTION |
|---|---|---|
| 1. Doesn’t a raw chemical/detergent like it should | • Chemical control knob not open far enough or too far open | • Open knob gradually until you achieve desired flow rate (2 [ A turns maximum) |
| • Chemical/detergent not thinned enough | • Add water to thin the solution | |
| • Chemical/detergent not proper type for suction use. | • Use Sears special cleaner/degreaser | |
| • Water control knob “ON” | • Turn water control knob “OFF” Only air and chemical Control knobs should be “ON” | |
| 2. Sputters when spraying chemical/ detergent | • Chemical control knob open too far | • Close knob until sputter stops |
| 3. Not enough spray force | • Water and/or air pressure too low | • Use Maximum water and air pressure available (not to exceed 175 psig) |
| • Water and air control knobs not fully open | • Open both knobs fully | |
| • Surface heavily soiled | • Scrub surface with rag or sponge to loosen dirt then rinse with air and water control knobs “ON” | |
| 4. Chemical/detergent doesn’t combine with water pressure inside of power washer | • Power Washer is not designed to do this | • To Wash or spray chemically use chemical and air control knobs ON only. To Rinse, use water and air control knobs ON only. |
