Frequently Asked Questions

Why don’t I have any water pressure?

Is the water hose attached to the pressure washer?

Is the water turned on?

Check for any kinks, leaks, or blockage in the hoses, fittings, or the nozzle.

Is the quick connect tip in place? (See Page 10).

Is the inlet filter screen free of debris? Check and remove debris if needed.

How do I get high pressure?

Use any color tip except black. The black tip is only used for low pressure detergent application.

How do I get the soap suction to work?

1.Connect the clear plastic chemical suction tube to the plastic hose barb on pump, insert the other end into your detergent.

2.Install the black spray tip to apply low pressure detergent.

Why doesn’t the pressure washer apply detergents with high pressure?

Detergents “bounce” off cleaning surfaces as fast as they are applied. The pressure washer’s features allow for a detergent to be drawn while in low pressure mode only. By applying detergent at low pressure, the effect of “bouncing” is reduced. Also, detergents are only effective when time is allowed for them to work on the surface of whatever is being cleaned. After applying the detergent, wait 1-3minutes while it works, and then proceed to rinse the surface with high pressure.

What maintenance do I need to perform on my pressure washer?

1.After turning off the pressure washer and the water, depressurize the hose by triggering the gun.

2.Remove the garden hose and high pressure hose from the pump.

3.Turn the motor on for 5 seconds to purge water from the pump. This will help protect the pump from damage.

4.Do not store your pressure washer in an area where the temperature will drop below 32˚ F.

5.Follow proper storage and winterizing instructions found on pages 13 and 14.

Operating Instructions and Parts Manual


Become familiar with these terms before operating the unit.

Cavitation - The shock of thousands of bubbles collapsing inside the pump quickly, pitting metal surfaces and seals. Cavitation is caused by lack of water at the inlet of the pump.

Chemical Injector - A chemical injector allows the chemical or soap to be injected into the water stream, making cleaning faster and easier than water alone.

Detergent Injection System - Cleaning detergents are drawn into the water stream making cleaning more effective by allowing detergents to saturate the soiled surface.

GPM (Gallons per Minute) - More water per minute can mean faster cleaning, especially when washing off materials like mud and road tar.

GFCI (Ground Fault Current Interrupter) - GFCI protects user from accidental electrocution (for electric powered pressure washers only).

High Pressure Outlet - A connection for high pressure hose.

HP (horsepower) - A unit of measure for work.

Nozzle (quick Connect Spray Tips) - The nozzle is the restriction at the end of the wand that creates the pressure. Nozzles have different spray patterns that can affect the width and strength of the spray. The40-degree(white) nozzle delivers a flat spray of about40-degrees.There’s also a25-degree(green) and the most popular15-degree(yellow) nozzles. The0-degree(red) nozzle should be used with caution, it can cut into wood and cause damage.

PSI (Pounds per Square Inch) - A unit of measure for pressure. It determines how much pressure is directly applied on the surface being cleaned. The pressure that is delivered by the pressure washer is directly responsible for breaking the bond between the debris and the surface being cleaned.

Thermal Relief - A technique used to reduce thebuild-upof high temperature water within a pressure washer pump caused when the spray gun trigger is closed. This system prevents internal pump damage by cycling water through pump when water reaches maximum water temperature. Warm water will discharge from pump onto ground.

Unloader - A device used to relieve the water pressure within the pump whenever the spray flow is blocked. It allows the motor to continue running when the operator releases the trigger on the spray gun and stops washing. It diverts the pressure, that would build up without the unloader, by taking the water from the exit side of the pump and loops it back to the inlet side in a continuous “bypass” mode. The unloader will return the flow of water to the spray gun when the operator presses the trigger.
