WARNING
Risk of electrocution.
Contact with power source can cause electric
shock or burn.
• NEVER spray near power source.
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
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
• Ensure spark plug, muffler, 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.

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
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.

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, press red button 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

burns.
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

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

Add Engine Oil
1. Place pressure washer on a flat, level surface.
2. Clean area around oil fill and remove yellow oil fill cap.
NOTE: See Oil Recommendations in Maintenance section.
Verify provided oil bottle is the correct viscosity for current
ambient temperature.
3. Using oil funnel (optional), slowly pour contents of
provided oil bottle into oil fill opening.
4. Replace oil fill cap and fully tighten.
Add Fuel
Fuel must meet these requirements:
• Clean, fresh, unleaded gasoline.
• A minimum of 87 octane/87 AKI (91 RON). High
altitude use, see High Altitude.
• Gasoline with up to 10% ethanol (gasohol) or up to
15% MTBE (methyl tertiary butyl ether) is acceptable.
To protect the fuel system from gum formation, mix in a fuel
stabilizer when adding fuel. See Storage. All fuel is not the
same. If you experience starting or performance problems
after using fuel, switch to a different fuel provider or change
brands. This engine is certified to operate on gasoline. The
emission control system for this engine is EM (Engine
Modifications).
1. Clean area around fuel fill cap, remove cap.
2. Slowly add regular unleaded fuel (A) to fuel tank (B). Be
careful not to overfill. Allow about 1.5" (4 cm) (C) of
tank space for fuel expansion.
3. Install fuel cap and let any spilled fuel evaporate before
starting engine.
High Altitude
At altitudes over 5,000 feet (1524 meters), a minimum
85 octane / 85 AKI (89 RON) gasoline is acceptable. To
remain emissions compliant, high altitude adjustment is
required. Operation without this adjustment will cause
decreased performance, increased fuel consumption, and
increased emissions. See an Authorized Briggs & Stratton
dealer for high altitude adjustment information. Operation of
the engine at altitudes below 2,500 feet (762 meters) with
the high altitude kit is not recommended.
