CONNECTING TO WATER SUPPLY
WATER SUPPLY
1. Select a water supply hose which is a quality grade of garden hose measuring at least
3/4” ID and no longer than 50 feet.
2. Check the water inlet strainer to ensure it is clean and free of any obstructions. As a
strainer becomes obstructed, it restricts the flow of water to the pump. This can result
in cavitations which will prematurely cause failure of pump components.
a. Using a screwdriver, remove the screen from the water inlet.
b. Clean or replace if necessary.
3. Connect the garden hose to the inlet of your high pressure pump. Thread the
connection together by hand until tight. Ensure the connection is tight at both ends
(at the pump inlet and at the water supply source).
4. Follow the incoming water requirements listed below:
a. Water pressure must be a minimum of 20 pounds per square Inch (PSI) and a
maximum of 125 PSI. (A typical outdoor faucet will generally supply this PSI if turned
completely “ON”.)
b. Incoming GPM (Gallons Per Minute) must be approximately one gallon more than
the outgoing GPM stated on the pressure washer nameplate. (You can check GPM by
timing how long it takes to fill a 5 gallon container).
5. Never allow the unit to operate without the incoming water line attached and the
water supply opened all the way.
NOTICE
• If there is a high mineral content in your water, it is highly recommended that a water
softener and an additional water strainer be added to the water inlet. This will help
prevent the possibility of excessive scale buildup inside the heat exchanger coil.
Pumps are water cooled. When the machine is running, ensure the trigger of the gun is
pressed to allow a constant flow of fresh water into and out of the pump. Do not let the
machine run for more than 30 seconds without pressing down on the trigger.

Most pumps are protected by a thermal valve. The thermal valve releases water if a
pump starts to run too hot. It will prevent catastrophic heat failure. However, the pump
may have suered damage and need maintenance, repair, or replacement. If it does not
reset and continues to leak water, the thermal valve may need to be replaced.

INITIAL START-UP & OPERATION
START-UP AND OPERATION (COLD WATER)
To start your pressure washer for the first time, follow these instructions step-by-step.
This starting information also applies if you have let the pressure washer sit idle for at
least a day.
1. Make sure the unit is level and placed on solid ground. Ensure the wheels are locked so
that it doesn’t move during operation.
2. Connect garden hose to water inlet on pressure washer pump. To do this, thread the
end of the hose into the inlet by hand until tight and secure.
3. Attach wand extension to spray gun. Tighten by hand.
4. Choose desired spray tip, pull back nozzle extension collar, insert spray tip and release
collar. Tug on spray tip to make sure it is securely in place. See Spray Tips on page 9 for
more information.
NOTICE
DO NOT run the pump without the water supply connected and turned on. Failure
to follow this rule will result in damage to the pump. Damage caused by running the
pump without water is not covered by warranty.
5 . Pull down on the collar of the quick-connect coupler, slide onto the gun connector
and let go of collar. Pull on hose to ensure the connection is tight.
