Quick Connect Spray Wand: Allows the user to quickly change the spray pattern. See next
sections for more details on your specic Spray Wand included with your machine.
Chemical Hose (not shown): Feeds cleaning agents into the pump to mix with the water. See How
to Apply Chemicals / Cleaning Solvents instructions.
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 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 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
The powerful spray from your pressure washer is capable of causing damage to
