CARBURETOR ADJUSTMENTS
I WARNING \
If any adjustments are made to the
engine while the engine is running
(e.g.
carburetor), keep clear of all
moving parts. Be careful of heated
surfaces and muffler.
Minor carburetor adjustment may be required to
compensate for differences in fuel, temperature,
altitude and load.
Refer to the separate engine manual packed with
your mower for carburetor adjustment informa­
tion.
LUBRICATION
Chute Deflector— The torsion spring and pivot
point should be lubricated periodically with light
oil to prevent any rust or binding. Deflector must
work freely.
Wheels— The wheels require no lubrication.
However, if the wheels are removed for any
reason, lubricate the surface of the axle bolt and
the inner surface of the wheel with light oil. A 4 oz.
plastic
bottle of light oil lubricant is available.
Order part number 737-0170. Engine oil may also
be used.
Engine— Follow engine manual for lubrication in­
structions.
Throttle— Periodically lubricate throttle control
lever and throttle wire assembly with a few drops
of light oil for ease of operation.
