Operation
3.
Release the collar, making sure it springs back and
re-seats to its original (non-retracted) position.
Check the connection by pulling on the hose to
ensure a positive connection.
Select Nozzle for Spray Gun
Your pressure washer is equipped with four high-
pressure nozzles and one low-pressure nozzle.
Generally, the wider the spray angle of the nozzle, the
lower the spray impact produced. Select the
appropriate nozzle for the job based on the following
table:
Attach Nozzle to Spray Gun
WARNING
Depressurize First
Any time you remove/install/change a nozzle, you
must depressurize hose line by squeezing the spray
gun trigger while the engine is off. Even if the
engine has been off for a long period of time, the
hose may remain dangerously pressurized.
1.
Make sure the engine is off and the hose line is
depressurized.
2.
To install the nozzle, pull the collar back and twist
the nozzle firmly into the coupler on the end of the
wand.
3.
Release the collar, making sure it springs back and
re-seats to its original (non-retracted) position.
Check the connection by pulling on the nozzle to
ensure a tight connection -- if correctly inserted,
nozzle will rotate but not pull out.
Prime the Water Supply
Turn On Water Supply and Squeeze the
Trigger
CAUTION: Water Pressure
Never run the pump without ball valves open for
tank supplied water. Operating the pressure
washer without a sufficient water in the tank will
damage the pump.
•
Turn on the water supply. Make sure the water
supply is steady and flowing at a rate 20% over the
rated flow of your pump. (Reference the flow rate
table under the Connect Hoses, Water Supply, and
Nozzle" section.)
•
Purge air from the water supply hose by squeezing
the trigger until a steady stream of water flows out of
the nozzle at low pressure. (Air in the hoses can
cause damage to the pump, so always make sure all
the air is out of the hoses before starting the engine
