GROUND FAULT CIRCUIT IN- TERRUPTER PROTECTION

This product is supplied with a Ground Fault Circuit Interrupter (GFCI) built into the power cord plug. This device pro- vides additional protection from the risk of electric shock. If power is interrupted in the line, the GFCI will automatically re-close the circuit to the load after pow- er is restored. Depending on the GFCI model, it may be necessary to manually operate the reset button to restore pow- er to the GFCI load circuit. If replace- ment of the plug or cord is needed use identical replacement parts.

WATER SUPPLY (Cold Water Only)

￿CAUTION

When connecting the water inlet to the water supply mains, local regulations of your water company must be observed. In some areas the unit must not be con- nected directly to the public drinking wa- ter supply. This is to ensure that there is no feedback of chemicals into the water

supply. Direct connection via a receiver tank or backflow preventer, for example, is permitted.

Dirt in the feed water will damage the unit. To avoid this risk, we recommend fitting a water filter.

!Garden hose must be at least 5/8 inch in diameter.

!Flow rate of water supply must not fall below 2 GPM (gallons per minute).

!Flow rate can be determined by run- ning the water for one minute into an empty 5-gallon container.

!The water supply temperature must not exceed 104°F/40°C.

!Never use the pressure washer to draw in water contaminated with sol- vents, e.g. paint thinners, gasoline, oil, etc.

!Always prevent debris from being drawn into the unit by using a clean water source.
