SERVICE ENGINE
Engine Warranty Maintenance Statement
Maintenance, repair, or replacement of the emission
control devices and systems on this engine, which are
being done at the customers expense, may be
performed by any nonroad engine repair establishment
or individual. Warranty repairs must be performed by an
authorized Authorized Service Center.
Adjusting Carburetor
NOTE: Carburetor is calibrated by the engine
manufacturer and should not require any
adjustments.
If engine is operated at altitudes above 1829 m
(6,000 ft), some carburetors may require a special
high altitude main jet. See your Authorized Service
Center.
Possible engine surging will occur at high rpm with
no load (with transmission in “N” neutral and
mower blade engagement lever disengaged). This is
a normal condition due to the emission control
system.
If engine is hard to start or runs rough, check the
Troubleshooting section of this manual.
After performing the checks in the troubleshooting
section and your engine is still not performing correctly,
contact an authorized Authorized Service Center.
Avoid Fumes
cCAUTION: Avoid injury. Engine exhaust
fumes can cause sickness or death:
- If it is necessary to run an engine in an
enclosed area, use an exhaust pipe extension
to remove the fumes.
- Always work in a well ventilated area.
