Depressurize System
To depressurize, turn engine/motor off, turn water supply
off and squeeze gun trigger 2-3 times .
WARNING
NEVER disconnect the high pressure discharge hose
from the machine while the system is pressurized .
To reduce the risk of bodily injury or property damage,
always follow this procedure whenever spraying is
stopped, when work is completed, and before checking
or repairing any part of the system .
1 . Engage the trigger safety latch .
2 . Turn the unit off .
3 . Remove the ignition cable from the spark plug .
4 . Shut off the water supply .
5 . Disengage the trigger safety latch and trigger the gun
to relieve pressure .
6 . Re-engage the trigger safety latch .
7 . Before overnight storage, long term storage, or
transporting unit, disconnect the water supply and
turn off the fuel supply valve .
Operating Tips
CAUTION
Never operate your pressure washer without water .
CAUTION
Never connect your pressure washer to a hot water
supply .
Connecting your pressure washer to a hot water
source will significantly reduce the life of the pump
and will void your warranty .
CAUTION
Running the unit for more than one minute without
spraying water causes heat to build up in the pump .
In the event that the pump gets too hot, a thermal
relief valve will open to release the hot water .
Running the unit without spraying water can damage
pump components and will void your warranty .
Stopping the Engine
1 . Press the engine switch to the "Off" position .
2 . Rotate the fuel valve to the "Off" position .
3 . Depressurize system .
4 . Turn off and unplug all hoses . Never start or stop the
pressure washer unless the water supply is turned on .
Operation at High Altitude
The density of air at high altitude is lower than at sea
level . Engine power is reduced as the air mass and
air-fuel ratio decrease . Engine power will be reduced
approximately 3½% for every 1000 feet of elevation
above sea level . Since the nozzle creates a fixed engine
load, the engine RPM may decrease indicating that the
engine is overloaded . This is a natural trend and cannot
be changed by adjusting the engine . At sufficiently high
altitudes increased exhaust emissions can also result due
to the increased enrichment of the air fuel ratio . Other
high altitude issues can include hard starting, increased
fuel consumption and spark plug fouling .
To alleviate high altitude issues other than the natural
power loss, Champion Power Equipment can provide a
high altitude carburetor main jet . The alternative main
jet and installation instructions can be obtained by
contacting Customer Support . Installation instructions
are also available in the Technical Bulletin area of the
Champion Power Equipment internet site .
The part number and recommended minimum altitude for
the application of the high altitude carburetor main jet is
listed in the table below .
Part Number
Standard main jet
ST188FD-1131000-17
Altitude main jet
188 .131017 .01
WARNING
Operation using the alternative main jet at elevations
lower than the recommended minimum altitude can
damage the engine . For operation at lower elevations, the
standard main jet must be used . Operating the engine
with the wrong engine configuration at a given altitude
may increase its emissions and decrease fuel efficiency
and performance .
