Water Supply (Cold Water Only)

• Water 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 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.
