viduals who are familiar with these rules of safe operation
should be allowed to use your mower.
4. Keep the area of operation clear of all persons, narticularly
small children and pets. Stop engine when they are i i the vicin
ity of your mower to help prevent blade contact or thrown
object injury. Although the area of operation shou J be com
pletely cleared of foreign objects, an object may have been
overlooked and could be accidentally thrown by thi mower in
any direction and cause serious personal injury to the operator
or any others allowed in the area.
5. Thoroughly inspect the area where the equipment is ;o be used.
Remove all stones, sticks, wire, bones, toys and otier foreign
objects which could be picked up and thrown by th i mower in
any direction and cause serious personal injury to the operator
or any others allowed in the area. Plan your mowin( pattern to
avoid discharge of material toward roads, sidewalk;, bystand
ers and the like. To help avoid a thrown objects iijury, keep
children, animals, bystanders and helpers at least 7 j feet from
the mower while it is in operation.
6. Always wear safety glasses with side shields or safi ty goggles
during operation or while performing an adjustment n repair, to
protect eyes from foreign objects that may be throv n from the
machine in any direction.
7. Wear sturdy, rough-soled work shoes and close-fiUing slacks
and shirts. Shirts and pants that cover the arms ard legs and
steel-toed shoes are recommended. Do not wear I )ose fitting
clothes or jewelry. They can be caught in moving parts. Never
operate a unit in bare feet, sandals, or sneakers.
8. Do not put hands or feet near or under rotating parts Keep clear
of discharge opening at all times as the rotating blad' i can cause
injury.
9. Many injuries occur as a result of the mower being aulled over
the foot during a fall. Do not hang on to the mowe' if you are
falling; release the handle immediately.
10. Never pull the mower toward you while you are wal dng. If you

to measure slopes before operating this unit on a sloped or hilly
area. If the slope is greater than 15°. as shown on the slope gauge,
do not operate this unit on that area or serious injury could result.
DO:
• Mow across the face of slopes; never up and down. Exercise
extreme caution when changing direction on slopes.
• Watch for holes, ruts, hidden objects, or bumps. Tall grass can
hide obstacles.
• Always be sure of your footing. A slip and fall can cause serious
personal injury.
DO NOT:
• Do not mow near drop-offs, ditches or embankments. The opera
tor could loose footing or balance.
• Do not mow slopes greater than 15° as shown on the slope
gauge.
• Do not mow on wet grass. Reduced footing could cause slipping.
III. CHILDREN
' Tragic accidents can occur if the operator is not alert to the presence
of children. Children are often attracted to the mower and the mow
ing activity. Never assume that children will remain where you last
saw them.
1. Keep children out of the mowing area and under the watchful
care of a responsible adult other than the operator.
2. Be alert and turn mower off it a child enters the area.
SAFE OPERATIONS PRACTICES (continued)

small children.
4. Never allow children under age 14 to operate the mower.
5. Use extreme care when approaching blind corners, shrubs,
trees, or other objects that may obscure your vision of a child or
hazard.
IV. SERVICE
1. 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 least 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 ail 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.
2. Never run an engine inside a closed area.
3. 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.
4. 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.
5. 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.
6. Keep all nuts, bolts, and screws tight to be sure the equipment
is in safe working condition.
7. Never tamper with safety devices. Check their proper operation
regularly.
8. 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.
9. Never attempt to make a wheel or cutting height adjustment
while the engine is running.
10. Grass catcher components are subject to wear, damage and
deterioration, which could expose moving parts or allow objects
to be thrown. For safe^ protection, frequently check
components and replace with manufacturer’s recommended
parts, when necessary.
11. Mower blades are sharp and can cut. Wrap the blade(s) or wear
gloves, and use extra caution when servicing them.
12. Do not change the engine governor setting or overspeed the
engine. Excessive engine speeds are dangerous.

WARNING
Ai
Do not mow on inclines with a slope in excess of 15 degrees (a rise of approximately 2-1/2 feet every 10 feet). A
riding mower could overturn and cause serious injury. If operating a walk-behind mower on such a slope, it is
extremely difficult to maintain your footing and you could slip, resulting in serious injury.
Operate RIDING mowers up and down slopes, never across the face of slopes.
Operate WALK-BEHIND mowers across the face of slopes, never up and down slopes.

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

CUTTING HEIGHT ADJUSTMENT
Adjustment may be made by removing and moving axle bolts
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, altii ude and
load. Refer to the separate engine manual packed /vith your
mower for carburetor adjustment information.
NOTE: A dirty air cleaner will cause an engine to n 'n rough.
Be certain air cleaner is clean and attached to the c 3rburetor
before adjusting carburetor.
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

MAINTENANCE
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.

Install the blade adapter on the crankshaft with the “star”
away from the engine. Refer to figure 17. Place the blade
with the side marked bottom (or with part number) facing
away from the adapter. Align the blade bell support over the
blade with the tabs in the hoies of the blade and insert the
hex bolt. Tighten the hex bolt to the torque listed in the “Blade
Mounting Torque” section below.
Blade Mounting Torque
Center Bolt: 450 in. lbs. min., 600 in. lbs. max.
Blade Adapter Bolts (if applicable): 200 in. lbs. min., 350 in.
lbs. max.
To ensure safe operation of your unit, all nuts and bolts must
be checked periodically for correct tightness.
Service air cleaner every 25 hours under norma! 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 should 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.
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 wilt
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
