IMPORTANT PRECAUTIONS – continued

Water Supply (Cold Water Only)

Water hose must be at least a 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 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.

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

Always prevent debris from being drawn into the unit by using a clean water source and an accessory water filter if required.
