BASIC ELEMENTS OF A PRESSURE WASHER
High Pressure Pump (located inside the shroud, not shown): Increases the pressure of the water supply.
Engine: Drives the high pressure pump.
High Pressure Hose: Carries the pressurized water from the pump to the gun and spray wand.
Spray Gun: Connects with spray wand to control water flow rate, direction, and pressure.
Gatling Spray Wand: Allows the user to quickly change
Chemical Hose: Feeds cleaning agents into the pump to mix with the water. See How To Apply Chemicals/ Cleaning Solvents instructions in this section.
BASIC ELEMENTS OF AN ENGINE
Refer to the engine manual for location and operation of engine controls.
Choke Control: Opens and closes carburetor choke valve.
Starter Grip: Pulling starter grip operates recoil starter to crank engine.
Engine Switch: Enables and disables ignition system.pressure washer terminology
PRESSURE WASHER
TERMINOLOGY
PSI: Pounds per Square Inch. The unit of measure for water pressure. Also used for air pressure, hydraulic pressure, etc.
GPM: Gallons Per Minute. The unit of measure for the flow rate of water.
CU: Cleaning Units. GPM multiplied by PSI. GPM x PSI = CU
Bypass Mode: Allows water to
Allowing the unit to run for more than
two minutes without the gun trigger pulled could cause overheating and damage to the pump.
Chemical Injection System: Mixes cleaners or cleaning solvents with the water to improve cleaning effectiveness.
Water Supply: All pressure washers must have a source of water. The minimum requirements for a water supply are 20 PSI and 5 gallons per minute.pressure washer operating features
PRESSURE WASHER OPERATING FEATURES
PRESSURE ADJUSTMENTS
The pressure setting is preset at the factory to achieve optimum pressure and cleaning. If you need to lower the pressure, it can be accomplished by these methods.
1.Back away from the surface to be cleaned. The further away you are, the less the pressure will be on the surface to be cleaned.
2.Change to the 40º nozzle - this nozzle delivers a less powerful stream of water and a wider spray pattern.
DO NOT attempt to increase pump pressure. A higher pressure setting
than the factory set pressure may damage pump.
TO USE SPRAY WAND
The nozzles for the spray wand are stored in the gatling spray wand. See chart to choose the correct nozzle for the job to be performed.
CHANGING NOZZLES ON SPRAY WAND
Risk of fluid injection. Do not
direct discharge stream toward persons, unprotected skin, eyes or any pets or animals. Serious injury will occur.
