BASIC ELEMENTS OF AN ENGINE
Refer to the Engine Owner’s Manual for location and operation of engine controls.

NOTICE: The engine is shipped without oil. Before starting engine, add the oil provided. Damage to the engine will occur if the engine is run without oil, this damage will not be covered under warranty.

PRESSURE WASHER TERMINOLOGY

PSI: Pounds per Square Inch. The unit of measure for water pressure. Also used for air pressure, hydraulic pressure, etc. Operating at pressures exceeding the maximum rating could result in damage to the unit and/or severe personal injury.

GPM: Gallons per Minute. The unit of measure for the flow rate of water.

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

Pressure Wand Assembly: This refers to the gun, wand and nozzle.

Pump: The pump moves the water through the system and delivers it to the pressure wand assembly. The nozzle creates the pressure.

Bypass Mode: Allows water to re-circulate 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 in between cleaning actions.

NOTICE: Allowing the unit to run for more than two minutes without the gun trigger being pulled could cause overheating and damage to the pump. Do not let the pressure washer run for more than two minutes in Bypass Mode. Turn off the engine and relieve the pressure in the gun during these extended situations.

Thermal Relief Valve: When the temperature inside the pump rises too high, this valve will open and release a gush of water in an effort to lower the temperature inside the pump. The valve will then close.

Pressure Relief Valve: The water heater coils are designed to operate safely at normal working pressure. The safety pressure relief valve prevents over pressurization of the high pressure system. Do not modify the pressure relief valve in anyway.

High Pressure Pump Oil: The preferred oil is SIMPSON® Premium Pump Crankcase Oil. If this oil is not available, an SAE 15W-40 oil may be used. Change the pump oil after the first 50 hours of operation and every 100 hours thereafter, or every 3 months.

Gasoline Engine Oil: Check engine oil level before each use. Refer to the Engine Owner’s Manual for correct procedure. 12V DC Battery: The 12V DC battery operates the engine’s electrical start system, after the engine is started the system will charge the battery and operate the burner. The 12V battery will need to be replaced regularly to ensure consistent performance. Recommended battery size: Group 24 battery

Burner Assembly: A device used to change fuel to heat energy. It is used to heat the water in the coil assembly and is designed to use a NO. #2 diesel fuel.

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

Temperature Control: The burner system is equipped with an adjustable temperature control. See Specification Insert for maximum temperature for each unit. Do not set thermostat above 195°F. The burner will shut off if insufficient water flow through the burner’s heater coil causes the outlet water temperature to be excessive.

Back Flow Preventer: Prevents backflow into a potable water system.

WARNING: To reduce the possibility of contamination always protect against backflow when connected to a potable water system

Pressure Switch: A switch which uses a pressure activated plunger to activate a microswitch, used to control the fuel solenoid in the burner system.

Flow Switch: A switch which responds to changes in water flow, water flow moves a magnet which ativates a reed or microswitch to control voltage to the fuel solenoid in the burner system.

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

High Pressure Hose: Only use a wire braid hose rated for the output pressure and temperature of the high pressure pump. See Specification Insert for the maximum temperature. Additional hose lengths can be added with quick twist couplers with a minimal loss in pressure of about .5 PSI per foot. Always inspect hoses for wear and replace if necessary. Avoid kinking or running over the hose to extend the hose life.
Hour meter: The analog hour meter operates whenever the engine is running and keeps track of how many hours the unit has been used.

Water Supply: The minimum requirements for a water supply are 20 psi and 5 Water Supply: The minimum requirements for a water supply are 20 psi at twice the stated water volume for the machine. If your water source is a well, the garden hose length can only be 30 ft. (9 m) maximum.

EVAP canister : Collects fuel vapors and later purges them so they burn in the combustion process.

OPERATION

PRESSURE WASHER OPERATING FEATURES

IMPORTANT: Become familiar with these features before operating this pressure washer.

PRESSURE ADJUSTMENTS
The pressure setting is preset at the factory to achieve op ti mum pressure and cleaning. If you need to lower the pressure, it can be accomplished by these methods.

1. Back away from the sur face to be cleaned. The further away you are, the less the pressure will be on the surface to be cleaned.
2. This pressure washer is equipped with an additional feature that allows the pressure setting to be adjusted.
3. To lower the pressure, turn the unloader control knob (N) (located under the hot water tank) counterclockwise to the desired pressure.
4. To return the pump pressure to the factory setting, turn the unloader control knob (N) (located under the hot water tank) clockwise until it stops.

NOTICE: DO NOT overtighten the pressure control knob, if overtightened the knob COULD break and result in immediate loss of water pressure and costly repairs to the unit.

HOW TO USE SPRAY WAND
The nozzles for the spray wand are stored in the nozzle holder on the panel assembly. Colors on the panel identify nozzle location and spray pattern. Refer to the following chart to choose the correct nozzle for the job to be performed.
