500137-N - 3 iN. (7.6 cM) chiPPER ShREDDER
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.
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.
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 chipper-shredder output will be reduced
approximately 3½% for every 1000 ft. 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, 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 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 high
altitude 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 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.
MAiNTENANcE
Always disconnect the spark plug wire during times of
inactivity, cleaning and maintenance. This will prevent any
accidental start up that may cause damage or injury.
Never operate a damaged or defective chipper-shredder.
Improper maintenance will void your warranty.
For Emission control devices and systems, read and
understand your responsibilities for service as stated in the
Emission Control Warranty Statement of this manual.
The owner/operator is responsible for all periodic maintenance.
Complete all scheduled maintenance in a timely manner.
Correct any issue before operating the chipper shredder.

Technical Support Team at .
Engine Maintenance
To prevent accidental starting, remove and ground spark plug wire
before performing any service.
Changing the Engine oil
Change oil when the engine is warm. Refer to the oil specification
to select the proper grade for your operating environment.
1. Remove the oil drain plug with a 15 mm socket and
extension. (Not included)
2. Allow the oil to drain completely.
3. Replace the drain plug.
