CAUTION! NEVER use any products not designed for pressure washer use, nor any products with chlorine or any caustic materials, including liquids containing solvents, trisodium phos- phate products, ammonia, or acid- based cleaners.

Fill the Detergent Dispenser only when the unit is not running or plugged in.

Setup

1.Check the water supply. Prior to using the Pressure Washer for the first time, it is ESSENTIAL to verify that the water supply is adequate. The Pres- sure Washer needs TWICE the water supply (or volume) than the stated water output (1.6 GPM). This Pres- sure Washer will need about 3-4 GPM to operate correctly and efficiently. If the water is being supplied by a well/ pump, make certain that the well/pump produces enough water to keep up with the Pressure Washer’s water demands. Water supply hoses should be heavy duty to withstand the forces involved. Water hoses up to 25’ long must be 5/8” ID. Water hoses up to 50’ long must be 3/4” ID. Do not use hoses longer than 50’. The more minerals in the water (the harder the water) you use, the more often mineral buildup will need to be cleaned out from the nozzles.

Flow rate of the water supply must nev- er be allowed to fall below 3 GPM.

To determine the water supply’s flow rate: Run the water at full for one minute into a 5 gallon container, and measure the amount of water in the container.

CAUTION! If the Pressure Washer is run with an inadequate water supply, the

pump will cavitate. Cavitation causes the pumptooperateloudlyandwilldamageit.

2.Arrange for a proper elec- trical supply. This unit uses

a large amount of current, espe- cially during start-up. Turn off power switch, then connect this unit only to a dedicated household circuit capable of providing ample current to it. A dedicated circuit has no additional loads (running devices) connected to it; shut off any appliances that slow down or lights that dim while the washer is running. For best results, connect the plug to that circuit’s outlet that is nearest to the circuit breaker panel.

3.Make sure the washer is clean and ready for use. En- sure the inlet water strainer, nozzle, and the rest of the Washer are com- pletely free of buildup or debris.

4.Plan out the job: Plan out what areas will be cleaned, how many ses- sions will be necessary, and how long the individual sessions of work will need to be. Plan to clean the higher portions first, because the higher portions will typically remain cleaner while the other areas are cleaned. Plan a safe direction for runoff to flow while the job is being performed, and plan on working your way in that direction. You will have a clearer idea of the time involved to clean the area after doing a test run, as explained on page 14.
