IMPORTANT PRECAUTIONS – continued
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.
