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
PSI: Pounds per Square Inch. The unit of measure for water pressure. Also used for air pressure,
hydraulic pressure, etc. Sometimes noted as “Bar”, another unit of measure.
GPM: Gallons per Minute. The unit of measure for the fl ow rate of water. Sometimes noted as L/min
(Liters per Minute).
CU: Cleaning Units. GPM multiplied by PSI equals CU.
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.
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 (not shown): 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.
Chemical Injection System: Mixes cleaners or cleaning solvents with the water to improve cleaning effectiveness. Depending on your machine, this could either be a Detergent Siphon Tube (which
is inserted into a container of detergent), or a Detergent Tank (which is fi lled with detergent and is an
integral part of the pressure washer frame).
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 - SPRAY WAND
