manual abstract
The supply hose should have a 3/4” inside diameter (ID) and be no longer than 50 feet. 2. The water supply pressure must be a minimum of 20 pounds per square inch (PSI) and a maximum of 125 PSI. The flow rate must be at least 3 gallons per minute (GPM). 3. Use a water softener if there is high mineral content in the water of your area. High mineral content causes excessive scale build-up in the coil/heat exchanger. 4. Un-roll the hose reel and then connect one end of the high pressure discharge hose to the water- gun assembly. ! Be sure all connections are securely tightened. Sudden release of high pressure streams can cause serious injury. OPERATING INSTRUCTIONS STARTING THE PRESSURE WASHER BEFORE STARTING THE PRESSURE WASHER 1. Read all safety instructions throughout this manual. 2. Be sure the motor switch is in the “OFF” position, red button pushed. 3. Ensure outlet is the proper voltage (120 volts). 4. Insert the male power plug into a grounded AC outlet. 5. Press and release the “RESET” button on the GFCI power cord. 6. Press “RESET” each time after plugging the GFCI power cord into a power source. COLD WATER OPERATION 1.

Cool down the heat exchanger by turning the burner knob “OFF” (0 position). Allow unit to run with trigger in the squeezed, “ON” position for at least 3 minutes. NOTE: On initial startup, water will begin turning hot in 30 seconds, reaching maximum temperature in 3 minutes with trigger squeezed.
