12 volt DC Battery (if equipped): The 12 volt battery operates the engine's electrical starting system. After the engine is started, the system will charge the battery and operate the burner (if equipped). The 12 volt battery will need to be replaced regularly to ensure consistent performance.

Back Flow Preventer: Prevents back flow of water from the pressure washer into a potable water system.

BTU (British Thermal Unit): The amount of work or energy it takes to raise the temperature of one pound of water by one degree Fahrenheit.

Burner Assembly: A device used to change fuel into heat energy. It is used to heat the water in the coil assembly and is designed to use #2 diesel fuel or kerosene.

Bypass Mode: Allows water to recirculate within the pump when the gun trigger is not pulled. This feature allows the operator to release the trigger gun and reposition themselves without having to turn the engine off between cleaning actions.

NOTE: Never allow the unit to run in bypass mode for longer than two minutes.

Chemical Injection System (if equipped): Mixes cleaners or cleaning solvents with the water to improve cleaning effectiveness.

CU: Cleaning Units. GPM multiplied by PSI equals CU.

Diesel Engine (if equipped): An compression-ignition engine that uses diesel fuel to create rotational force for mechanical work.

EVAP canister (if equipped): A device that collects fuel vapors and later purges them so they burn in the combustion process.

Flow switch: A switch which responds to changes in water flow. The flow of water moves a magnet that operates a reed or micro switch. The switch controls voltage to the fuel solenoid in the burner system.

Gasoline Engine (if equipped): An internal combustion engine that uses gasoline as fuel to create rotational force for mechanical work.

GPM: Gallons Per Minute. The unit of measurement for the flow of water.

Spray gun: The device that is held to control the direction and flow of high-pressure water.

High-pressure Hose: A plastic or rubber hose that is constructed to withstand the high pressure output of a pressure washer. Never repair a high-pressure hose, always replace the damaged hose with one that is rated the same or higher pressure and within the temperature range of your pressure washer.

High Pressure Pump Oil: A lubricant that is specifically designed for use inside a high-pressure water pump. The preferred oil is SIMPSON® Premium Pump Crankcase Oil. If this oil is not available, SAE 15W-40 oil may be used. Refer to the section on Pump Maintenance in this manual as to the service intervals for your pump.

Hour Meter (if equipped): An analog or digital display timing device that records how many hours the pressure washer engine has ran in its lifetime. Use this information for preventative maintenance service intervals.

Nozzle: A device for the metering of fluids. The size and machining of the orifice determines the spray pattern as well as the rate of flow for a given pressure.

Pressure Relief Valve: A protective mechanical device that opens to atmosphere when the system pressure exceeds a preset level. NEVER tamper with or modify the pressure relief valve in anyway. SERIOUS INJURY or DEATH may result.

Pressure Switch: An electrical switch that activates at preset pressure levels through the function of a diaphragm. The pressure switch is used to control the fuel solenoid in the burner system.

Pressure Wand Assembly: The collection of parts that includes the gun, wand and nozzle.

PSI: Pounds per Square Inch. The unit of measurement for fluid or gas pressure. Exceeding the maximum operating pressure could result in damage to the unit, SERIOUS INJURY or DEATH.

Pump: Mechanical device that accelerates the movement of water through the pressure washer system. The pressure is created by the restrictive flow of the nozzle.

Temperature Control: A device that controls the temperature of the water. The adjustable temperature control (if equipped) allows the operator to tailor the temperature to the cleaning requirements. Never set the control above 195^ F. The burner will automatically shut off if insufficient water flow through the burner coil causes the temperature to rise above the setting.

Temperature Relief Valve (TRV): A protective device that opens to atmosphere should the temperature rise above a preset level. The TRV is typically located on the output side of the pump. Should the water temperature rise too high due to recirculation, the valve will open allowing cooler water to enter the pump. The valve will then close.

Unloader Valve: A mechanical device that adjusts itself due to the rate and pressure of fluid flowing through it. In a pressure washer, the unloader valve reroutes water through the pump when the gun trigger is released. This allows the water to circulate through the pump without undo pressure building. The unloader valve can be used as a pressure regulating device in certain situations.

Water Column (if equipped): A measurement of NG or LP gas pressure by the displacement of water within the manometer measuring device.

Water Supply: The source of water for the pressure washer. Typically the minimum requirement is twice the rated volume for the machine at 20 PSI.

• Sweep any loose dirt and debris from the surface you will be pressure washing.
• Cover nearby plants to protect them from over spray and detergent.
• Only use the white, 40^ nozzle when washing windows or painted items like automobiles. Always start far away and move closer with care.
• If you are using the pressure washer to prepare siding for painting and the existing paint my be from before 1977, lay down tarps to collect the paint chips. They may contain lead and need to be disposed of at a proper disposal facility.
• Use only detergents or soaps that are approved for pressure washer use.

PRESSURE WASHING

• A wider spray equals faster cleaning, while a tighter spray equals deeper cleaning.
• Do not aim the nozzle straight at a surface. Hold the wand at a 45^ angle to the surface at a distance that cleans well without causing damage.
• Keep the nozzle about four feet away from siding to prevent damage to the surface.
• Start washing at the bottom, move your way upward then rinse from the top down.
• Avoid driving water behind siding, trim and into window frames.
• When using soap, work on smaller areas and do not let the soap dry.
