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 release pressure in tank.
• Fill or drain fuel tank outdoors.
• DO NOT overfill tank. Allow space for fuel expansion (25mm from top).
• 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
• Ensure spark plug, exhaust, fuel cap, and air cleaner are in place.
• DO NOT crank engine with spark plug removed.
When Operating Equipment
• DO NOT tip engine or equipment at angle which causes fuel to spill.
• DO NOT spray flammable liquids.
When Transporting or Repairing Equipment

• 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.
DANGER
Risk of electrocution.
Contact with power source can cause electric shock
or burn.
• NEVER spray near power source.

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 releasing 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.
• Firmly grasp spray gun with both hands when using high pressure
spray to avoid injury when spray gun kicks back.
WARNING
Engine exhaust fumes contain carbon monoxide, an
odourless, colourless, 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.
• ONLY operate pressure washer outdoors.
• Do not allow 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 vapours may
be inhaled.
• Read all instructions with the mask so you are certain the mask will
provide the necessary protection against inhaling harmful vapours.
