OPERATION
Stopping the Engine
1. Turn the throt tle down to the “SLOW” position.
2. Turn the fuel valve to the “OFF” position.
3. Let the engine run until fuel starvation has stopped
the engine. This usually takes a few minutes.
4. Turn the engine switch to the “OFF” position.
5. Disconnect spark plug wire.
Important: Always ensure that the Fuel Valve and the
Engine Switch are in the “OFF” position when the engine
is not in use.
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.
NOTE
Do not let the collection bag fill to capacity before
emptying. It is recommended to empty the bag
before it fills completely to minimize damage to the
bag.
NOTE
As the engine shuts off and the blades wind down,
some noises in the flail housing can be made, these
are normal, but any weird noises may be damage
and if these occur the unit should be inspected.
NOTE
OPERATION
Emptying the Collection Bag
1. Turn the throt tle down to the “SLOW” position.
2. Stop the engine.
3. Turn the fuel valve to the “OFF” position.
4. Disconnect the spark plug wire.
5. Using your hands, release the draw string on the
collection bag.
6. Remove the collection bag from the deflector chute
and empty bag.
7. Once emptied, reconnect the collection bag by
pulling the draw string tight, then reconnect the
spark plug wire, turn the fuel valve “ON”, and
restart the engine.
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 feet 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.
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.
