. Before and while moving backwards, took behind and down for
small children.
, Never allow children under age 14 to operate the mower.
. Use extreme care when approaching blind corners, shrubs,
trees, or other objects that may obscure your vision of a child or
hazard.
SERVICE
Use extreme care in handling gasoline and other fuels. They are
extremely flammable and the vapors are explosive.
a. Use only an approved container.
b. Never remove gas cap or add fuel while the engine is run-
ning. Allow engine to cool at ieast two minutes before refuel-
ing.
C. Replace gasoline cap securely and wipe off any spilled
gasoline before starting the engine as it may cause a fire or
explosion.
d. Extinguish all cigarettes, cigars, pipes and other sources of
ignition.
e. Never refuel machine indoors because flammable vapors will
accumulate in the area.
f. Never store the machine or fuel container inside where there
IS an open flame or spark such as a gas water heater, space
heater, or furnace.
. Never run an engine inside a closed area.
. To reduce fire hazard, keep mower free of grass, leaves, or other
debris build-up. Clean up oil or fuel spillage. Allow mower to
cool at least 5 minutes before storing.
. Before cleaning, repairing, or inspecting, make certain the blade
and all moving parts have stopped. Disconnect the spark plug
wire, and keep the wire away from the spark plug to prevent
accidental starting.
. Check the blade and engine mounting bolts at frequent intervals
for proper tightness. Also, visually inspect blade for damage
(e.g., bent, cracked). Replace with blade which meets original
equipment specifications.
. Keep all nuts, bolts, and screws tight to be sure the equipment
is in safe working condition.
. Never tamper with safety devices. Check their proper operation
regularly.
. After striking a foreign object, stop the engine, remove the wire
from the spark plug, and thoroughly inspect the mower for any
damage. Repair the damage before starting and operating the
Mower,
. Never attempt to make a wheel or cutting height adjustment
while the engine is running.
. Grass catcher components are subject to wear, damage and
deterioration, which could expose moving parts or allow objects
to be thrown. For safety protection, frequently check
components and replace with manufacturers recommended
parts, when necessary.
Mower blades are sharp and can cut. Wrap the blade(s) or wear
gloves, and use extra caution when servicing them.
Do not change the engine governor setting or overspeed the
engine. Excessive engine speeds are dangerous.
TO REDUCE THE RISK OF INJURY, DO NOT
OPERATE MOWER UNLESS REAR TRAILING

TO STOP ENGINE AND BLADE
1. Release the blade control handie to stop the engine and
blade.
WARNING: The blade continues to rotate for a
few seconds after the engine is shut off.
2. Disconnect the spark plug wire and ground it against the
engine to prevent accidental starting while equipment is
unattended.
USING YOUR ROTARY MOWER
Be sure that lawn is clear of stones, sticks, wire, or other
objects which could damage lawn mower or engine. Such
objects could be accidently thrown by the mower in any
direction and cause serious personal injury to the operator
and others.
For best results, do not cut wet grass because it tends to
stick to the underside of the mower, preventing proper dis-
charge of grass clippings, and could cause you to slip and
fall. New grass or thick grass may require a narrower cut.
The best mowing pattern is one that allows the clippings to
discharge towards the uncut part of the lawn. This permits
recutting of the clippings to further pulverize them. When cut-
ting high weeds, discharge towards cut portion, then recut at
right angles to first direction.
For a healthy lawn, never cut off more than one-third of
the total length of the grass. Lawn should be cut in the fall
as long as there is growth.
WARNING: If you strike a foreign object, stop
the engine. Remove wire from spark plug, thor-
oughly inspect the mower for any damage, and
repair the damage before restarting and oper-
ating the mower. Extensive vibration of the
mower during operation is an indication of
damage. The unit should be promptly
inspected and repaired.
ADJUSTMENTS
WARNING: Do not at any time make any
А adjustment to lawn mower without first stop-
ping engine and disconnecting spark plug
wire.
CUTTING HEIGHT ADJUSTMENT
Adjustment may be made by removing and moving axle boits
to desired position. Cutting heights will be raised as axle
bolts are moved to a lower hole and lowered as axle bolts are
moved to a higher hole in the deck. All axle bolts must be
mounted in the same relative position. Cupped washers
must be assembled so that the cupped side of the washers
are against the deck. Refer to figure 10.
CARBURETOR ADJUSTMENTS
WARNING: If any adjustments are made to the
engine while the engine is running (e.g. carbu-
retor), keep clear of all moving parts. Be care-
ful of heated surfaces and muffler.
Minor carburetor adjustment may be required to com-
pensate for differences in fuel, temperature, altitude and
load. Refer to the separate engine manual packed with your
mower for carburetor adjustment information.
NOTE: A dirty air cleaner will cause an engine to run rough.
Be certain air cleaner is clean and attached to the c irburetor
before adjusting carburetor.
LUBRICATION
WARNING: Always stop engine and dis connect
spark plug wire before cleaning, lubricating or
doing any kind of work on lawn mowei,
A
Blade Control—Lubricate the pivot points on the b ade con-
trol handle and the brake cable at least once a se ison with
light oil. See figure 15. The blade control must oper ite freely
in both directions.

Chute Deflector—The torsion spring and pivot po nt should
be lubricated periodically with light oil to prevent ay rust or
binding. Deflector must work freely.
Wheels—The wheels require no lubrication. Howe ser, if the
wheels are removed for any reason, lubricate the surface of
the axle bolt and the inner surface of the wheel wit 1 light oil.
Engine cil may also be used.
Engine—Follow engine manual for lubrication instr ictions.
MAINTENANCE
WARNING: Be sure to disconnect anc ground
the spark plug wire before perform ing any
repairs or maintenance.

NOTE: When tipping the unit, empty the fuel tank and keep
engine spark plug side up.
TROUBLE SHOOTING
Refer to page 13 of this manual for trouble shootinci informa-
tion.
CUTTING BLADE
When removing the cutting blade for sharpening o replace-
ment, protect hands by using heavy gloves or a ra¢| to grasp
the cutting blade. Remove the bolt and blade support or bell
washer which hold the blade and adapter to tre engine
crankshaft. Remove the blade and adapter from {ле сгапК-
shaft.
12
if the blade is secured to the blade adapter with two bolts,
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.
A
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 exces-
sive vibration when rotating at high speeds, may cause dam-
age to the mower and could break, causing personal injury.
The blade can be tested by balancing it on a round shaft
screwdriver. Remove metal from the heavy side until it bal-
ances evenly. It is recommended that the blade always be
removed from the adapter for the best test of balance.
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 (or engine oil). Lubricating the
bolt holes, bolts and inner surface of the nuts is also recom-
mended.
THREE BOLT BLADE MOUNTING
Install the blade to the blade adapter with the side of the
blade marked “bottom” (or with part number) facing away
from the adapter. Refer to figure 16. insert two hex bolts up
through the blade and adapter and secure with lock washers
and hex nuts. Tighten according to “Blade Mounting Torque”
section below.
Place the blade and blade adapter assembly on the engine
crankshaft.
NOTE: If the adapter is keyed, make sure the key in the
adapter is aligned with the key slot on the crankshaft.

To ensure safe operation of your unit, all nuts and bolts must
be checked periodically for correct tightness.
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 dis-
charge of grass clippings at the next cutting.
The deck may be cleaned by tilting the mower and scraping
clean with a suitable tool (make certain the spark plug wire is
disconnected).
ENGINE
Refer to the separate engine manual for engine mainte-
nance instructions.
Maintain engine oil as instructed in the separate engine
manual packed with your unit. Read and follow instructions
carefully.
13
Service air cleaner every 25 hours under normal conditions.
Clean every few hours under extremely dusty conditions.
Poor engine performance and flooding usually indicates that
the air cleaner should be serviced. To service the air cleaner,
refer to the separate engine manual packed with your unit.
The spark plug shouid be cleaned and the gap reset once a
season. Spark plug replacement is recommended at the
start of each mowing season; check engine manual for
correct plug type and gap specifications.
Clean the engine regularly with a cloth or brush. Keep the
cooling system (blower housing area) clean to permit proper
air circulation which is essential to engine performance and
life. Be certain to remove all grass, dirt and combustible
debris from muffler area.
OFF-SEASON STORAGE
The following steps should be taken to prepare lawn mower
for storage.
1. Clean and lubricate mower thoroughly as described in
the lubrication instructions.
2. Refer to engine manual for correct engine storage
instructions.
3. Coat mower's cutting blade with chassis grease to
prevent rusting.
4, Store mower in a dry, clean area. Do not store next to
corrosive materials, such as fertilizer.
NOTE: When storing any type of power equipment in an
unventilated or metal storage shed, care should be taken to
rust-proof the equipment. Using a light oil or silicone, coat
the equipment, especially cables and all moving parts.
