WARNING

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

Breathing carbon monoxide can cause
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 operate pressure washer inside any building or

enclosure, even if doors or windows 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.

Use of pressure washer can create
puddles and slippery surfaces.

High pressure spray could cause you to
fall if you are too close to the cleaning
surface.

• Keep spray nozzle between 20 to 60 CM (8 to 24 IN)

away from cleaning surface.

• Operate this unit on 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 relatively
unstable location.

• Firmly grasp spray gun with both hands when using high

pressure spray to avoid injury when gun kicks back.

Rapid retraction of starter cord (kickback)
will pull hand and arm toward engine
faster than you can let go.

Broken bones, fractures, bruises or
sprains could result.

• ALWAYS point gun in safe direction and squeeze spray

gun trigger, to release pressure and avoid kickback
each time, before starting engine. Engage trigger lock
when not in use.

• 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 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 gun kicks back.

Petrol and its vapors are extremely
flammable and explosive.

Fire or explosion can cause severe burns
or death.

WHEN ADDING PETROL

• Turn pressure washer OFF and let it cool at least

2 minutes before removing gas cap.

• Fill petrol tank outdoors.
• DO NOT overfill tank. Allow space for petrol

expansion.

• Keep petrol away from sparks, open flames, pilot

lights, heat, and other ignition sources.

• DO NOT light a cigarette or smoke.

WHEN OPERATING EQUIPMENT

• DO NOT tip engine or equipment at angle which causes

petrol to spill.

• DO NOT spray flammable liquids.

WHEN TRANSPORTING OR REPAIRING
EQUIPMENT

• Transport/repair with petrol tank EMPTY or with petrol

shutoff valve OFF.

WHEN STORING PETROL OR EQUIPMENT WITH
PETROL 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 petrol
vapors.

Spray contact with electrical wiring can
result in electrocution.

• Keep water spray away from electric wiring or fatal

electric shock may result.

Running engines produce heat.
Temperature of muffler and nearby areas
can reach or exceed 65°C (150°F).

Severe burns can occur on contact.

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

• Do not touch hot surfaces and avoid hot exhaust gases.
• Allow equipment to cool before touching.
• Keep at least 1.5 M (5 FT) clearance on all sides of

pressure washer including overhead.
