RISK OF EXPLOSION

OR FIRE

HAZARD WHAT CAN HAPPEN HOW TO PREVENT IT

Do not use acids, gasoline, kerosene,or any other flammable materials in thisproduct. Use only householddetergents, cleaners, and degreasersrecommended for use in PressureWashers. Work in a well ventilated area.

Use of acids, unapproved chemicals,or flammable solvents with thisproduct could cause injury or death.

RISK TOBREATHING

• Some cleaning fluids contain sub-stances which could cause injury toskin, eyes, or lungs.

• Use only cleaning fluids specificallyrecommended for high pressurewashers. Follow manufacturersrecommendations. Do not usechlorine bleach or any othercorrosive compound.

RISK TO FLUID INJECTION

• Your washer operates at fluidpressures and velocities high enoughto penetrate human and animal flesh,which could result in amputation orother serious injury. Leaks caused byloose fittings or worn or damagedhoses can result in injection injuries.DO NOT TREAT FLUID INJECTIONAS A SIMPLE CUT! See a physicianimmediately!

• Never place hands in front of nozzle.• Do not direct discharge stream at

persons or animals.• Make sure hose and fittings are

tightened and in good condition.Never hold onto the hose or fittingsduring operation.

• Do not operate pressure washer withworn or abraded hose.

• Never attach or remove wand or hosefittings while system is pressurized.

• Injuries can result if system pressureis not reduced before attemptingmaintenance or disassembly.

• To relieve system pressure, placeon/off switch in off position, turn offwater supply, and pull gun triggeruntil water stops flowing.

• Use only hose and high pressureaccessories rated for pressure higherthan your pressure washer's p.s.i.

RISK OFELECTRICAL

SHOCK

• Water spray directed at electricaloutlets or switches, or objects con-nected to an electrical circuit, couldresult in a fatal electrical shock.

• Unplug any electrically operatedproduct before attempting to clean it.Direct spray away from electric outletsand switches.

• This product is powered byelectricity. It contains and sprayswater and other conductive liquids.Improper operation could result inelectrocution.

• The Ground Fault CircuitInterrupter (GFCI) will not functionproperly unless connected to a fullygrounded electrical circuit!

• Extension cords can lead to electricalshock.

• Always connect cordset to aproperly grounded and polarizedelectrical circuit. Your cordset isequipped with a Ground Fault CircuitInterrupter (GFCI) for your personalprotection.

• If damaged, the entire cordsetassembly must be replaced by anauthorized service center. Refer toGrounding Instructions.

• Do not use with extension cords.

Restricting any of the pressurewasher ventilation openings willcause serious overheating and couldcause fire.

The powerful spray from your pressure washer is capable of causingdamage to surfaces such as wood, glass, automobile paint, auto striping

and trim, and delicate objects such as flowers and shrubs. Before spraying, check the item tobe cleaned to assure yourself that it is strong enough to resist damage from the force of thespray. Avoid the use of the concentrated spray stream except for very strong surfaces likeconcrete and steel.

SAVE THESE INSTRUCTIONS

GROUNDING INSTRUCTIONSThis product must be grounded. If itshould malfunction or breakdown,grounding provides a path of leastresistance for electric current to reducethe risk of electric shock. This productis equipped with a cord having anequipment-grounding conductor and agrounding plug. The plug must beplugged into an appropriate outlet thatis properly installed and grounded inaccordance with all local codes andordinances.

Improper connectionof the equipment-

grounding conductor can result inrisk of electrocution. Check with aqualified electrician or servicepersonnel if you are in doubt as towhether the outlet is properlygrounded. Do not modify the plugprovided with the product-if it willnot fit the outlet, have a properoutlet installed by a qualifiedelectrician. Do not use any type ofadapter with this product.

EXTENSION CORDSUse additional length of high pressurehose instead of extension cords toavoid voltage drop and power loss tothe motor, and to prevent overheating.DO NOT USE EXTENSION CORDS.NOTE: The use of additional length ofhigh pressure hose will lower thepressure washer's PSI below 1600.

GROUND FAULT CIRCUITINTERRUPTER PROTECTIONThis pressure washer is provided witha ground fault circuit interrupter (GFCI)built into the plug of the power supplycord. This device provides additionalprotection from the risk of electricshock. Should replacement of the plugor cord become necessary, use onlyidentical replacement parts thatinclude GFCI protection.
