DANGER: CARBON MONOXIDE
Using a pressure washer indoors CAN KILL YOU IN MINUTES. Pressure washer exhaust contains carbon
monoxide (CO). This is a poison gas you cannot see or smell. If you can smell the pressure washer exhaust, you
are breathing CO. But even if you cannot smell the exhaust, you could be breathing CO.
NEVER use a pressure washer inside homes, garages, crawlspaces, or other partly enclosed areas. Deadly levels
of carbon monoxide can build up in these areas. Using a fan or opening windows and doors does NOT
supply enough fresh air. ONLY use a pressure washer outside and far away from windows, doors, and vents.
These openings can pull in pressure washer exhaust.
Even if you use a pressure washer correctly, CO may leak into the home. ALWAYS use a battery-powered or
battery-backup CO alarm in the home. If you start to feel sick, dizzy, or weak after the pressure washer has been
running, move to fresh air RIGHT AWAY. See a doctor. You may have carbon monoxide poisoning.
WARNING: The exhaust from this product contains chemicals known to the State of California to
cause cancer, birth defects, or other reproductive harm.
WARNING: This pressure washer may emit highly flammable and explosive gasoline vapors, which
can cause severe burns or even death if ignited. A nearby open flame can lead to explosion even if it
isn’t directly in contact with gasoline.
• Do not operate near open flame.
• Do not smoke near pressure washer.
• Always operate on a firm, level surface.
• Always turn pressure washer off before refueling. Allow pressure washer to cool for at least 2 minutes before
removing fuel cap. Loosen cap slowly to relieve pressure in tank.
• Do not overfill fuel tank. Gasoline may expand during operation. Do not fill to the top of the tank. Allow
for expansion.
• Always check for spilled fuel before operating.
• Empty fuel tank before storing or transporting the pressure washer.
• Do not allow children or non-qualified persons to operate.
GENERAL SAFETY PROCEDURES
6
WARNING: This pressure washer produces heat when running. Temperatures near exhaust can
exceed 1500 F (650 C).
Do not touch hot surfaces. Pay attention to warning labels on the pressure washer identifying hot parts of the
machine.
Allow pressure washer to cool down after use before touching the engine or areas of the pressure washer that
become hot during operation.
CAUTION: Misuse of this pressure washer can damage it and shorten its life.
Only use the pressure washer for its intended purposes.
Turn the engine switch to “OFF” position when the engine is not running.
The high pressure stream of water can cut through skin and cause serious injury. Do not aim the stream of water
at yourself or at any one else, including animals.
Hoses and tubes can become damaged from coming in contact with a hot engine or muffler. Always double check
the hose for perforations before starting up the machine and keep it clear of the engine and the muffler.
Kickback from operation can cause the user to fall down. Always operate the pressure washer on a level and non-
elevated surface to prevent the risk of falling.
Always wear safety goggles to protect from possible mishaps with the stream or detergents. Always be aware of the
dangers associated with the detergents and chemicals that you are working with.
Attach all hoses before starting the engine.
SAVE THESE INSTRUCTIONS – This manual contains important instructions for the WEN® Pressure
Washer that should be followed during installation and maintenance of the pressure washer.
Pressure washers vibrate in normal use. During and after the use of the pressure washer, inspect both the pressure
washer as well as extension and power supply cords for damage resulting from vibration. Have damaged items
repaired or replaced as necessary. Do not use plugs or cords that show signs of damage such as broken or cracked
insulation.
