5. Alternatively. for electric start, plug in the supplied electrical
cord into the starter. Press the electric start button and make
sure that the mains supply voltage is 120 V~ 60 Hz (Fig. 12).

6. To start a cold engine: When the engine starts, move the
choke to RUN position.
Stopping the Engine
To stop the engine in an emergency situation or during normal
operation, simply remove the engine key.
Operation at High Altitude
The density of air at high altitudes is lower than at sea level.
Engine power is reduced as the air mass and air-fuel ratio
decrease. Engine power and snowblower output will be reduced
approximately 3½% for every 1000 ft. of elevation above sea level.
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, CPE can provide a high altitude carburetor main jet. The
alternative main jet and installation instructions can be obtained
by contacting our Technical Support Team. Installation instructions
are also available in the Technical Bulletin area of the CPE website.
The part number and recommended altitude range for the
application of the high altitude carburetor main jet is listed in the
following table.
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 high
altitude 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 originally
supplied 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.
