CARBURETOR ADJUSTIVIENTS
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.
A
Minor carburetor adjustments may be required to
compensate for differences in fuel, temperature,
altitude and ioad.
To adjust carburetor, refer to the
separate engine manual packed with your mower.
NOTE:
A dirty air cleaner will cause an engine to run
rough. Be certain air cleaner is clean and attached to
the carburetor before adjusting carburetor. Refer to
the separate engine manual.

LUBRICATION
WARNING: Always stop engine and dis­
connect spark piug wire before cieaning,
lubricating or doing any kind of work on
lawn mower.
Blade Control —Lubricate the pivot points on the
blade control handle and the brake cable at least
«N once a season with light oil. The blade control must
operate freely in both directions.
Chute Deflector —The torsion spring and pivot point
should be lubricated periodically with light oil to pre­
vent any rust or binding. Deflector must work freely.
Wheels —^The mower may be provided with ball bear­
ing wheels. Lubricate at least once a season with light
oil. Also, if the wheels are removed for any reason,
lubricate the surface of the axle bolt and the inner sur­
face 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 instruc­
tions.
Chain —The chain should be lubricated periodically
with a few drops of light oil to prevent any rust or bind­
ing. Use very little or no oil if unit is being used in a
dusty or sandy area.
MAINTENANCE
A WARNING: Be sure to disconnect and
ground the spark plug wire before per­
forming any repairs or maintenance.
A
NOTE:
When tipping the unit, empty the fuel tank and
keep engine spark plug or muffler side up.
TROUBLE SHOOTING
Refer to page 16 of this manual for trouble shooting
information.
CUTTING BLADE
When removing the cutting blade for sharpening or
replacement, protect hands by using heavy gloves or
a rag to grasp the cutting blade. Remove the bolt and
bell washer which hold the blade and adapter to the
engine crankshaft. Remove the blade and adapter
from the crankshaft.
If the blade or blade adapter needs replacing, remove
the two small bolts, lock washers and nuts which hold
the blade to the adapter.
WARNING: Periodically inspect the blade
adapter for cracks, especially if you
strike a foreign object. Replace when
necessary.
When sharpening the blade, follow the original angle
of grind as a guide. It is extremely important that each
cutting edge receives an equal amount of grinding to
prevent an unbalanced blade. An unbalanced blade
will cause excessive vibration when rotating at high
speeds, may cause damage to the mower and could
break, causing personal injury.
It is recommended that the blade always be removed
from the adapter for the best test of balance.
The blade can be tested by balancing it on a round
shaft screwdriver. Remove metal from the heavy side
until it balances evenly.
Before reassembling the blade and the blade adapter
to the unit, lubricate the engine crankshaft and the
inner surface of the blade adapter with light oil.
Lubricating the bolt holes, bolts and inner surface of
the nuts with light oil is also recommended. A 4 oz.
plastic bottle of light oil lubricant is available. Order
part number 737-0170. Engine oil may also be used.
When replacing the blade, be sure to install the blade
with the side of the blade marked “Bottom” (or with
part number) facing the ground when the mower is in
the operating position.
Blade Mounting Torque
Center Bolt: 450 in. lbs. min., 600 in. lbs. max.
Blade Adapter Bolts: 200 in. lbs. min., 350 in. lbs. max.
To insure safe operation of your unit, all nuts and
bolts must be checked periodically for correct tight­
ness.
DECK
The underside of the mower deck should be cleaned
after each use to prevent a buildup of grass clippings,
leaves, dirt or other matter. If this debris is allowed to
accumulate, it will invite rust and corrosion, and may
cause an uneven discharge of grass clippings at the
next cutting.
