WARNING

The engine exhaust from this product contains chemicals

known to the State of California to cause cancer, birth

defects, or other reproductive harm.

WARNING

Use of pressure washer can create puddles and slippery surfaces.

Kickback from spray gun can cause you to fall.

• Operate pressure washer from a stable surface.

• The cleaning area should have adequate slopes and drainage to reduce the possibility of a fall due to slippery surfaces.

• Be extremely careful if you must use the pressure washer from a ladder, scaffolding, or any other similar location.

• Firmly grasp spray gun with both hands when using high pressure spray to avoid injury when spray gun kicks back.

WARNING

Running engine gives off carbon monoxide, an odorless, colorless, poison gas.

Breathing carbon monoxide can cause headache, fatigue, dizziness, vomiting, confusion, seizures, nausea, fainting or death.

Some chemicals or detergents may be harmful if inhaled or ingested, causing severe nausea, fainting, or poisoning.

• Operate pressure washer ONLY outdoors.

• Keep exhaust gas from entering a confined area through windows, doors, ventilation intakes, or other openings.

• DO NOT start or run engine indoors or in an enclosed area, even if windows and doors are open.

• Use a respirator or mask whenever there is a chance that vapors may be inhaled.

• Read all instructions with mask so you are certain the mask will provide the necessary protection against inhaling harmful vapors.

Safety - 3

SAFETY

WARNING

or burn.

• NEVER spray near power source.

WARNING

Fuel and its vapors are extremely flammable and explosive.

Fire or explosion can cause severe burns or death.

WHEN ADDING OR DRAINING FUEL

• Turn pressure washer OFF and let it cool at least 2 minutes before removing fuel cap. Loosen cap slowly to relieve pressure in tank.

• Fill or drain fuel tank outdoors.

• DO NOT overfill tank. Allow space for fuel expansion.

• If fuel spills, wait until it evaporates before starting engine.

• Keep fuel away from sparks, open flames, pilot lights, heat, and other ignition sources.

• DO NOT light a cigarette or smoke.

WHEN STARTING EQUIPMENT

• Transport / repair with fuel tank EMPTY or with fuel shutoff valve OFF.

• Disconnect spark plug wire.

WHEN STORING FUEL OR EQUIPMENT WITH FUEL IN TANK

• Store away from furnaces, stoves, water heaters, clothes dryers, or other appliances that have pilot light or other ignition source because they can ignite fuel vapors.

WARNING

Starter cord kickback (rapid retraction) can result in bodily injury. Kickback will pull hand and arm toward engine faster than you can let go.

Broken bones, fractures, bruises, or sprains could result.

• NEVER pull starter cord without first relieving spray gun pressure.

• When starting engine, pull cord slowly until resistance is felt and then pull rapidly to avoid kickback.

• After each starting attempt, where engine fails to run, always point spray gun in safe direction and squeeze spray gun trigger to release high pressure.

Exhaust heat/gases can ignite combustibles, structures or damage fuel tank causing a fire.

• DO NOT touch hot parts and AVOID hot exhaust gases.

• Allow equipment to cool before touching.

• Keep at least 5 feet (1.5 m) of clearance on all sides of pressure washer including overhead.

• Code of Federal Regulation (CFR) Title 36 Parks, Forests, and Public Property require equipment powered by an internal combustion engine to have a spark arrester, maintained in effective working order, complying to USDA Forest service standard 5100-1C or later revision. In the State of California a spark arrester is required under section 4442 of the California Public resources code. Other states may have similar laws.

WARNING

Unintentional sparking can result in fire or electric shock.

WHEN ADJUSTING OR MAKING REPAIRS TO YOUR PRESSURE WASHER

• Disconnect the spark plug wire from the spark plug and place the wire where it cannot contact spark plug.

WHEN TESTING FOR ENGINE SPARK

• Use approved spark plug tester.

• DO NOT check for spark with spark plug removed.
