The powerful spray from your pressure washer is capable of causing
damage to surfaces such as wood, glass, automobile paint, auto

stripping and trim, and delicate objects such as flowers and shrubs. Before spraying,
check the item to be cleaned to assure yourself that it is strong enough to resist
damage from the force of the spray. Avoid the use of the concentrated spray stream
except for very strong surfaces like concrete and steel.

Operating without flow of water will result in equipment damage. Operating the
pressure washer with water supply shutoff will void your warranty. You should never run
this pressure washer for more than 2 minutes without pulling the trigger to allow cool
water to enter the pump and the heated (recirculated) water to exit.

HOW TO PREVENT IT

• Never point spray wand at, or spray people
