Important Safety Rules

4

1.) Read owner's manual completely.

Serious injury or death can result if safety instructions are not followed. You must be
16 or older to operate this machine. Keep untrained people away.

2.) Skin puncture hazard.

High pressure fluid can inject under skin resulting in serious injury including
amputation. Do not direct spray at people or animals.

-If skin injection happens, seek IMMEDIATE surgical treatment.

-Do not check for leaks with hand. Instead, use a piece of cardboard to check for
leaks.

-Do not use unit if exterior hose damage is evident. Make sure all fittings are tight
before starting. Relieve system pressure before servicing.

-Know how to stop engine and bleed pressures quickly. Be thoroughly familiar with
the controls.

-Make sure accessories meet the unit's temperature and pressure limits.

-Stop engine, bleed pressure, and engage spray gun safety lock before leaving unit

unattended.

3.) Risk of fire and explosion.

Hot exhaust fumes from engine can cause fire. Gasoline is highly flammable and
explosive. You can be burned or seriously injured when handling fuel.

-Position muffler at least 7 feet from combustible objects.

-Before adding fuel, stop the engine and keep heat, sparks, and flame away. Do not

add fuel when engine is running or still hot. No smoking near engine.

-Do not pump fuel directly into engine at gas station. Static charge can build and

ignite fuel. Use a UL approved fuel container to transfer gas to the engine. Wipe up

fuel spills immediately.

-Only store and handle fuel outdoors. Gasoline vapors can ignite if they collect

inside an enclosure. Explosion can result.

-Do not change or add to exhaust system. Fire can result.

-Do not change or add fuel tanks or fuel lines. Fire can result.

-Before each use, check fuel tank and fuel lines for leaks. Any fuel leak is a fire

hazard. Fix any fuel leaks before starting engine.

-During transportation take precautions to make sure pressure washer will not tip

over and cause a fuel leak fire hazard.

4.) Poisonous gas.

This machine gives off carbon monoxide, a poisonous gas that can kill you. You

CANNOT smell it, see it, or taste it.

-ONLY run machine outdoors and away from air intakes.

-NEVER run machine inside homes, garages, sheds, or other semi-enclosed spaces.
These spaces can trap poisonous gases, EVEN IF you run a fan or open doors and
windows.

If you start to feel sick, dizzy, or weak while using this machine, shut it off and get to

fresh air RIGHT AWAY. See a doctor. You may have carbon monoxide poisoning.
