Be certain the trigger gun is locked in the "OFF"
position.
. The nozzle assembly should be disconnected from the
gun/wand assembly at this by retracting the locking ring
on the quick-connect fitting to remove the nozzle.
WATER SuPPly
. Select a water supply hose which is a quality grade of garden
hose measuring at least /4" ID and no longer than 50 feet.
 Check the water inlet strainer to ensure it is clean and free of
any obstructions. Periodic cleaning of the water strainer will help
prevent pump problems. As a strainer becomes obstructed, it
restricts proper flow of water to the pump. This can result in
cavitations which will cause premature failure of pump packings
and valves. Using a screw driver, remove the screen; clean or
replace if necessary.
. Connect the hoses.
a. Connect one end of the water supply hose to the water inlet
of the unit.
b. Connect the other end of the hose to your pressurized water
supply.
NOTE: Do not use a non-pressurized water supply (i.e. from a
well or pond) with this unit.
c. Connect the high pressure discharge hose to the water outlet
of the unit.
4. Follow the incoming water requirements listed below:
a. Water pressure must be a minimum of 5 pounds per square
inch (PSI) and a maximum of 5 PSI. (A typical outdoor
faucet will generally supply this PSI if turned completely
"ON".)
b. Incoming GPM 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.
c. Incoming water temperature must not exceed 125°F (52°C).
Excessive pump damage may result if the water temperature
exceeds this acceptable level.
5. Never allow the unit to operate without the incoming water line
attached and the water supply turned all the way on.
