\ WARNjNG j
If any adjustments are made to the
engine while the engine is running
(e.g. carburetor), disengage all
clutches and blades. 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.
All carburetor adjustments should be made with
the air cleaner on engine. Air cleaner mounting
screw must be in carburetor when engine is run.
Best adjustment is made with a fuel tank half full
of gasoline.
Refer to the separate engine manual packed with
your mower for carburetor adjustment informa­
tion.
LUBRICATION
FIGURE 15.
IMPORTANT
Always stop engine and disconnect
spark
piug wire before cleaning,
lubricating or doing any kind of
work on lawn mower.
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.
Discharge Chute Door Mechanism—The torsion
spring and pivot point should be lubricated
periodically with light oil to prevent any rust or
binding. Door must work freely.
