100386 - 4200 PSI PRESSURE WAShER
MAINTENANCE
17
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 the warranty.
Stopping the Engine
1. Turn the fuel valve to the “OFF” position.
2. Let the engine run until fuel starvation has stopped the
engine. This usually takes a few minutes.
3. Press the engine switch to the “OFF” position.
4. Depressurize system.
5. Turn off water supply and unplug all hoses. Never start or
stop the pressure washer unless the water supply is turned
on.
Important:
Always ensure that the fuel valve and the engine
switch are in the “OFF” position when the engine is not in use.
NOTICE
If the engine will not be used for a period of two (2) weeks
or longer, please see the Storage section for proper engine
and fuel storage.
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 and output will be reduced
approximately 3½% for every 1000 ft. (305 m) of elevation
above sea level. This is a natural trend and cannot be changed
by adjusting the engine. At 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. In order to select the correct high altitude
main jet it is necessary to identify the carburetor model. For
this purpose, a code is stamped on the side of the carburetor.
Select the correct main jet part number corresponding to the
carburetor code found on your particular carburetor.

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.
MAINTENANCE
Make certain that the pressure washer is kept clean and stored
properly. Only operate the unit on a flat, level surface in a clean,
dry operating environment. DO NOT expose the unit to extreme
conditions, excessive dust, dirt, moisture or corrosive vapors.
WARNING
Never operate a damaged or defective pressure washer.
WARNING
Improper maintenance will void your warranty.
NOTICE
Maintenance, replacement, or repair of emission control
devices and systems may be performed by any non-road
engine repair establishment or individual.
The owner/operator is responsible for all periodic maintenance.
Complete all scheduled maintenance in a timely manner.
Correct any issue before operating the pressure washer.
