Controls and Features
Pressure Washer Terminology
High Pressure Pump
Increases the pressure of the water supply.
Engine
Drives the high pressure pump. Refer to the Engine Operator's
manual packed with your pressure washer for location and
operation of engine controls.
High Pressure Hose
Carries the pressurized water from the pump to the gun and
spray wand.
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 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.
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.
Figure 4-1
Spray Gun
Connects with spray wand to control water flow rate, direction
and pressure. Only Model CC4033 is equipped with the Dial-N-
Wash pressure adjustment and side handle.
Quick-Connect Spray Wand
Allows the user to quickly change out high pressure nozzles.
Refer to "How To Use Spray Wand" instructions in Controls and
Features section.
Detergent Siphon Hose (not shown)
Feeds cleaning agents into the pump to mix with the water. See
"How To Apply Chemicals/Cleaning Solvents" instructions in
Controls and Features section.
Detergent 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. If your water source is a well, the garden hose length can
only be 30 ft. (9 m) max.
