GROUND FAULT CIRCUIT

INTERRUPTER PROTECTION

This pressure washer is provided with a ground-fault circuit-interrupter (GFCI) built into the plug of the power-supply cord. This device provides additional protection from the risk of electric shock. Should replacement of the plug or cord become necessary, use only identical replacement parts that include GFCI protection.

SERVICING OF A DOUBLE-

INSULATED PRODUCT

In a double-insulated product, two systems of insulation are provided instead of grounding. No grounding means is provided on a double-insulated product, nor should a means for grounding be added to the product. Servicing a double-insulated product requires extreme care and knowledge of the system, and should be done only by qualified service personnel. Replacement parts for a double-insulated product must be identical

to the parts they replace. A doubleinsulated product is marked with the words “DOUBLE INSULATION” or “DOUBLE INSULATED”. The symbol “ ” may also be marked on the product.

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 connected directly to the public drinking water 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 1/2

inch or 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 solvents, e.g. paint thinners, gasoline, oil, etc.

 Always prevent debris from being

drawn into the unit by using a clean water source.
