Frequently Asked Questions:

What kind of oil do I use?

Engine: Refer to Engine manual for oil recommendations.

Pump: See page 16 and 17.

My Pressure Washer won’t start..(See Engine manual for starting instructions)

Has gasoline been added to the engine?

Is engine on/off switch in “on” position? (If applicable)

Has engine been primed or choked?

Adequate amount of oil in engine? (Some models are equipped with a "Low Oil Shut Down" switch)

Is fuel valve in the “Open” position. (if applicable)

Pull trigger on spray gun to release pressure.

How do I apply chemicals?

Wand/Lance must be in the low pressure setting. See page 13.

Chemical hose must be attached to pump and fully submerged in chemical/soap-See page 8 and 13.

Chemical adjustment knob must be in open position. See page 15.

How do I adjust the pressure?

The pressure unloader is factory pre-set at the maximum pressure and should not be increased. The pressure can be lowered by following the instructions on page 14. Do not attempt to increase the engine speed to achieve a higher pressure. Excessive pressure will damage the pump.

I don’t have enough pressure...

Do you have an adequate water supply(5 gallons per minute at 20 p.s.i.)?

All hoses free of kinks and leaks?

Is wand in high pressure setting? See page 11 & 12.

Is spray nozzle blocked or partially obstructed? If so, clear and replace. See page 18.

Is the high pressure hose longer than 100 feet?

Has unit ran for a long period of time without pulling the spray gun trigger?

What type of chemicals/soaps can I use?

Use only chemicals/soap designed for use in pressure washers.

Do not use chlorine bleach or any other corrosive compound; this will cause damage to the pump.

Who can I call if I have questions or any problems?

Call us at 1-800-888-2468, Extension 2, Monday through Saturday, 8:00 a.m. to 8:00 p.m., E.S.T.

How do I drain the oil?

Engine: Refer to the Engine manual for this information.

Pump: See page 16 and 17.

Where can I purchase parts and/or accessories?

Service parts can only be obtained through our many Authorized Warranty Service Centers. For a location nearest you, call us at 1-800-888-2468, Extension 2.

Accessories can be purchased at an Authorized Warranty Service Center or at one of the many local retailers.

SAFETY

The powerful spray from your pressure washer is capable of causing damage 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 to be cleaned to assure yourself that it is strong enough to resist damage from the force of the spray. Avoid the use of the concentrated spray stream except for very strong surfaces like concrete and steel.

Operating unit with water supply shutoff without flow of water will result in equipment damage. Operating the pressure washer with water supply shutoff will void your warranty. You should never run this pressure washer for more than 2 minutes without pulling the trigger to allow cool water to enter the pump and the heated (recirculated) water to exit.

Read Owner’s Manual. Do not operate equipment until you have read Owner’s

Manual for Safety, Operation, and Maintenance Instructions.

This product is not equipped with a spark arresting muffler. If the product will be used around flammable materials, or on land covered with materials such as agricultural crops, forest, brush, grass, or other similar items, then an approved spark arrester must be installed and is legally required in the state of California. It is a violation of California statutes section 130050 and/or sections 4442 and 4443 of the California Public Resources Code, unless the engine is equipped with a spark arrester, as defined in section 4442, and maintained in effective working order. Spark arresters are also required on some U.S. Forest Service land and may also be legally required under other statutes and ordinances.

Engine exhaust contains chemicals known, in certain quantities, to cause cancer, birth defects or other reproductive harm.

GLOSSARY

PSI: Pounds per square inch is a unit of measure for pressure.

GPM: Gallons Per Minute (Flow Rate)

Cleaning Units: GPM x PSI

Vertical: A vertical pressure washer has the pump located underneath the engine.

Horizontal: A horizontal pressure washer has the pump located behind the engine.

Multi-Reg wand/lance: This type of wand/lance is black and has a spray nozzle which is adjustable from a pencil stream (0°) to a wide angle fan spray (60°). The spray can be adjusted by twisting the nozzle clockwise and/or counterclockwise. Also, the high and low pressure settings can be controlled by moving the nozzle in and out. See page 11.

Hi-Low:This type of lance has one chrome tube with a black knob on the nozzle end. The knob can be turned clockwise and counterclockwise to control the high and low pressure settings. It comes with a ¼” NPT, 15° nozzle. To obtain different spray patterns, the nozzle must be removed and replaced with one of the desired degree. The available patterns are 0°, 25°, and 40°. When replacing nozzles, be sure to use one of the same flow rating. Be sure to apply teflon tape to nozzle threads to prevent leaks. See page 11.

Dual Lance: This type of lance has two chrome tubes with a handle grip near the gun/lance connection and two nozzles on the end. The handle grip can be turned clockwise and counter clockwise to control the high and low pressure settings. It also comes with a ¼” NPT, 15° high pressure nozzle. To obtain different spray patterns, the nozzle must be removed and replace with one of the desired degree. The available patterns are 0°, 25°, and 40°. NOTE: Be sure not to remove the chemical nozzle. It is the nozzle with the larger hole in it. When replacing nozzles, be sure to use one of the same flow rating. Be sure to apply teflon tape to nozzle threads to prevent leaks. See page 11.

Quick Connect: This type of lance is equipped with a female quick connect coupler on the end. This allows the user to quickly change out high-pressure nozzles for different spray patterns and change to the soap nozzle for low pressure and chemical/soap applications. See page 12 .

By Pass Mode: During normal operation, a continuous flow of cold water is needed to keep the pressure washer pump operating at a safe temperature. If the pressure washer is operated without an adequate water supply, or operated for more than two (2) minutes without pulling the trigger, the pump will overheat and cause serious damage. Any damage to the pump due to these causes will not be covered under warranty.
