Ground Fault Circuit Interrupter

(GFCI) Protection

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

SAVE THESE INSTRUCTIONS!

WATER SUPPLY (Cold Water Only)

CAUTION

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

!Water 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 running 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.

CLEANING TIPS

Deck Cleaning

(with or without detergent). Pre-rinse deck and surrounding area with fresh water. If using Kärcher Deck Wash, apply to surface at low pressure. For best results, limit your work area to smaller sections of approximately 25 square feet. Allow Deck Wash to remain on surface 1-3 minutes. Do not allow detergent to dry on surface. Rinse at high pressure in a long sweeping motion keeping the spray nozzle approximately 3-6 inches from the cleaning surface. Always clean from top to bottom and from left to right. When moving on to a new section of the cleaning surface, be sure to overlap the previous section to eliminate stop marks and ensure a more even cleaning result.

If needed, use special wash brush attachment (not included) to remove stubborn dirt. Rinse at high pressure from top to bottom in an even sweeping motion keeping the spray nozzle approximately 6 inches from the cleaning surface.

Cement Patios, Brick and Stone
