DANGER: Risk of explosion or fire

What can happen How to prevent it

Spilled gas­line and it’s vapors can become ignited from cigarette sparks, electrical arcing, exhaust gases and hot engine components such as

the muffler.

Shut off engine and allow it to cool before adding fuel to the tank.

Use care in filling tank to avoid spilling fuel. Move pressure washer away

from fueling area before starting engine.

Heat will expand fuel in the tank which could result in spillage and possible fire explosion.

Operating the pressure washer in an explosive environment could result in a fire.

Materials placed against or near the pressure washer can interfere with its proper ventilation features causing overheating and possible ignition of the materials.

Keep maximum fuel level 1/2" (12.7 mm) below bottom of filler neck

to allow for expansion.

Operate and fuel equipment in well-ventilatedareas free from obstructions. Equip areas with fire extinguisher suitable for gas­line fires.

Never operate pressure washer in an area containing dry brush or weeds.

Muffler exhaust heat can damage painted surfaces, melt any material sensitive to heat (such as siding, plastic, rubber, vinyl or the pressure hose, itself), and damage live plants.

Improperly stored fuel could lead to accidental ignition. Fuel improperly secured could get into the hands of children or other unqual­fied persons.

Use of acids, toxic or corrosive chemicals, poisons, insecticides, or any kind of flammable solvent with this product could result in serious injury or death.

Always keep pressure washer a min­mum of 4' (1.2 m) away from surfaces (such as houses, automobiles or

live plants) that could be damaged from muffler exhaust heat.

Store fuel in an OSHAapproved container, in a secure location away from work area.

Do not spray flammable liquids.

DANGER: RISK TO BREATHING (Asphyxiation)

What can happen How to prevent it

Breathing exhaust fumes will cause serious injury or death! Engine exhaust contains carbon monoxide,

an odorless and deadly gas.

Operate pressure washer in a well-ventilatedarea. Avoid enclosed areas such as garages, basements, etc.

Never operate unit in a location occupied by humans or animals.

DANGER: RISK of FLUID INJECTION and Laceration

What can happen

Your pressure washer operates at fluid pressures and velocities high enough to penetrate human and animal flesh, which could result in amputation or

other serious injury. Leaks caused by loose fittings or worn or damaged hoses can result in injection injuries. DO NOT TREAT FLUID INJECTION AS

A SIMPLE CUT! See a physician immediately!

How to prevent it

Inspect the high-pressurehose regularly. Replace the hose immediately if it is

damaged, worn, has melted from contacting the engine, or shows any signs of cracks, bubbles, pinholes, or other leakage. Never grasp a high-pressurehose that

is leaking or damaged.

Never touch, grasp or attempt to cover a pinhole or similar water leak on the highpressure hose. The stream of water IS under high pressure and WILL penetrate skin.

Never place hands in front of nozzle.

Injuries can result if system pressure is not reduced before attempting maintenance or disassembly.

Direct spray away from self and others.

Make sure hose and fittings are tightened and in good condition. Never hold onto the hose or fittings during oper­tion.

Do not allow hose to contact muffler.

Never attach or remove wand or hose fittings while system is pressurized.

To relieve system pressure, shut off engine, turn off water supply and pull gun trigger until water stops flowing.

Use only accessories rated equal to or higher than the rating of the pressure washer.

DANGER: RISK OF INJURY FROM SPRAY

What can happen

How to prevent it

High-velocityfluid spray can cause objects to break, propelling particles at high speed.

Light or unsecured objects can become hazardous projectiles.

Always wear ANSI-approvedZ87.1 safety glasses. Wear protective clothing to protect against accidental spraying.

Never point wand at or spray people or animals.

Always secure trigger lock when wand is not in service to prevent accidental operation.

Never permanently secure trigger in pull-back(open) position.

Danger: RISK of unsafe operation

What can happen

How to prevent it

Unsafe oper­tion of your pressure washer could lead to serious injury or death to you or others.

Do not use chlorine bleach or any other corrosive compound.

Become familiar with the oper­tion and controls of the pressure washer.

Keep operating area clear of all persons, pets and obstacles.

Do not operate the product when fatigued or under the influence of alcohol or drugs. Stay alert at all times.

Never defeat the safety features of this product.

Do not operate machine with missing, broken or unauthorized parts.

Never leave wand unattended while unit is running.

If proper starting procedure is not followed, engine can kickback causing serious hand and arm injury.

The spray gun/wand is a powerful cleaning tool that could look like a toy to a child.

Reactive force of spray will cause gun/wand to kickback, and could cause the oper­tor to slip or fall or misdirect the spray. Improper control of gun/ wand can result in injuries to self and others.

If engine does not start after two pulls, squeeze trigger of gun to relieve pump pressure. Pull starter cord slowly until resistance is felt. Then pull cord rapidly to avoid kickback and prevent hand or arm injury.

Keep children away from the pressure washer at all times.

Do not overreach or stand on an unstable support.

Do not use pressure washer while standing on a ladder.

Grip gun/wand firmly with both hands. Expect the gun to kickback when triggered.

DANGER: Risk of Injury or Property Damage When Transporting or storing

What can happen

Fuel or oil can leak or spill and could result in fire or breathing hazard. Serious injury or death can result. Fuel or oil leaks will damage carpet, paint or other surfaces in vehicles

or trailers.

How to prevent it

If pressure washer is equipped with a fuel shut-offvalve, turn the valve to the off position before transporting to avoid fuel leaks. If pres­ sure washer is not equipped with a fuelshut-offvalve, drain the fuel from tank before trans­ porting. Only transport fuel in anOSHA-approvedcontainer. Always place pressure washer on a protective mat when transporting to protect against damage to vehicle from leaks. Remove pressure washer from vehicle immediately upon arrival at your destination.

WARNING: RISK of Bursting

What can happen

How to prevent it

Over inflation of tires could result in serious injury and property damage.

Use a tire pressure gauge to check the tires pressure before each use and while

inflating tires; see the tire sidewall for the correct tire pressure.

NOTE: Air tanks, compressors and similar equipment used to inflate tires can fill small tires similar to these very rapidly. Adjust pressure regulator on air supply to no more than the rating of the tire pressure. Add air in small increments and frequently use the tire gauge to prevent over inflation.

Do not use acids, gasoline, ker­sene, or any other flammable materials in this product. Use only household detergents, cleaners and degreasers recommended for use in pressure washers.

Wear protective clothing to protect eyes and skin from contact with sprayed materials.

WARNING: RISK OF electrical Shock

What can happen How to prevent it

Spray directed at electrical outlets or switches, or objects connected to an electrical circuit, could result in a

fatal electrical shock.

Unplug any electrically operated product before attempting to clean it. Direct spray away from electric outlets and switches.

WARNING: RISK OF INJURY FROM LIFTING

What can happen How to prevent it

Serious injury can result from attempting to lift too heavy an object.

The pressure washer is too heavy to be lifted by one person. Obtain assistance from others before lifting.

OPERATION

Pressure Adjustments

The pressure setting is preset at the factory to achieve optimum pres­ sure and cleaning. To lower the pressure, follow these instructions.

1.Back away from the surface to be cleaned. The further away you are, the less the pressure will be on the surface to be cleaned.

2.Change to the 40˚ nozzle (white). This nozzle delivers a less powerful stream of water and a wider spray pattern. Refer to

Spray Wand Nozzles.

3.Adjust the pressure reg­lator on the pump. Turn the pressure reg­lator knob (R) counterclockwise to lower pressure. Once you have finished using your pressure wash­ er, return the pressure reg­lator to its original position by turning it clockwise.

Caution: Do not try to turn pressure regulator knob past thebuilt-instop or damage to the pump will result.
