Terms

• PSI - Pounds per square inch (PSI) is the unit to measure the pressure of water. In relation to a pressure washer, the higher the PSI number, the greater the pressure and stripping power produced.
• GPM - Gallons per minute (GPM) is the flow rate of water. In relation to a pressure washer, the greater the GPM, the greater the flow or rinsing power produced.
• CU - Cleaning units express the efficiency of the pressure washer. Cleaning units are calculated by multiply the PSI by the GPM. The higher the CU, the more efficient the pressure washer.

Preparation

• Read all warning and instructions in this and all manuals that came with the pressure washer.
• Remove all toys, bikes, lawn furniture, etc. from the work area if they are not to be cleaned.
• Sweep any loose dirt and debris from the surface you will be pressure washing.
• Cover nearby plants to avoid damaging them with the pressure washer spray.
• Use caution when spraying windows. Always use the white, 40^ nozzle and stay at least 4 feet away.
• Lay tarps down to collect paint chips and other debris blown off by the spray. Exterior paints used before 1977 may contain lead and will produce chips that will need to be collected and disposed of at a hazardous waste facility.

Pressure Washing

• A wider spray equals faster cleaning, while a tighter spray equals deeper cleaning.
• Keep the nozzle about 4 feet away from siding to avoid damage.
• Start washing siding at the bottom and work your way up, then rinse from the top down.
• Avoid driving water up behind siding.
• Use overlapping strokes for even cleaning.
  • Work in small areas to keep the soap from drying.
• Do not aim the nozzle straight at the surface. Hold the wand at a 45^ angle to the surface at a distance that cleans well without causing damage.

Adjusting Pressure

The pressure setting is preset at the factory to achieve optimum pressure and cleaning. If you should need to lower the pressure, it can be accomplished by the following methods.

• Back away from the surface to be cleaned. The further you position the nozzle from the surface to be cleaned, the lower the pressure to reach the surface.
• Change to the white, 40^ nozzle. This nozzle produces a lower pressure, wider width spray.

Your unit may be equipped with an additional feature that allows you to adjust the pressure.

To lower the pressure, turn the knob counterclockwise to the desired pressure.

To return the pressure to the factory setting, turn the knob clockwise until it stops.

NOTICE

PUMP DAMAGE

Leaving water inside the pump during freezing weather will cause severe damage to the pump. To avoid costly damage, always treat the pump with SIMPSON® Pump Guard to remove the trapped water and to fill the pump with a lubricating, antifreeze solution.

SIMPSON® Pump Guard (purchase separately) is formulated to protect your pump during long-term storage and from freezing damage. Pump Guard should be used throughout the season to keep the seals pliable and well lubricated. Before storing the unit for winter or for when there is a chance of freezing weather, use pump guard to remove all traces of water from the internal cavities while filling them with an antifreeze solution.

Simply use Pump Guard by following these easy steps:

1. Screw the Pump Guard adapter into the garden hose input on the pump.
