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

Safe
Operation
Practices
General Operation
1. Read this operator’s manual carefully in its entirety before
attempting to assemble this machine. Read, understand, and
follow all instructions on the machine and in the manual(s)
before operation. Keep this manual in a safe place for future
and regular reference and for ordering replacement parts.
2. Be completely familiar with the controls and the proper use of
this machine before operating it.
3. This machine is a precision piece of power equipment, not a
plaything. Therefore, exercise extreme caution at all times.
Your unit has been designed to perform one job: to mow grass.
Do not use it for any other purpose.
4. Never allow children under 14 years old to operate this
machine. Children 14 years old and over should read and
understand the instructions in this manual and should be
trained and supervised by a adult.
5. Only responsible individuals who are familiar with these rules
of safe operation should be allowed to use this machine.
6. Thoroughly inspect the area where the equipment is to be
used. Remove all stones, sticks, wire, bones, toys and other
foreign objects which could be tripped over or picked up
and thrown by the blade. Thrown objects can cause serious
personal injury.
7. Plan your mowing pattern to avoid discharge of material toward
roads, sidewalks, bystanders and the like. Also, avoid discharg-
ing material against a wall or obstruction which may cause
discharged material to ricochet back toward the operator.
8. To help avoid blade contact or a thrown object injury, stay
in the operator zone behind the handles and keep children,
bystanders, helpers and pets at least 75 feet from the mower
while it is in operation. Stop machine if anyone enters the area.
9. Always wear safety glasses or safety goggles during operation
and while performing an adjustment or repair to protect your eyes.
Thrown objects which ricochet can cause serious injury to the
eyes.
10. Wear sturdy, rough-soled work shoes and close-fitting slacks
and shirts. Shirts and pants that cover the arms and legs
and steel-toed shoes are recommended. Never operate this
machine in bare feet, sandals, slippery or light weight (e.g.
canvas) shoes.
11. Do not put hands or feet near rotating parts or under the cutting
deck. Contact with the blade can amputate hands and feet.
12. A missing or damaged discharge cover can cause blade
contact or thrown object injuries.
13. Many injuries occur as a result of the mower being pulled
over the foot during a fall caused by slipping or tripping. Do
not hold on to the mower if you are falling; release the handle
immediately.
14. Never pull the mower back toward you while you are walking. If
you must back the mower away from a wall or obstruction first
look down and behind to avoid tripping and then follow these
steps:
a. Step back from the mower to fully extend your arms.
b. Be sure you are well balanced with sure footing.
c. Pull the mower back slowly, no more than half way toward you.
d. Repeat these steps as needed.
15. Do not operate the mower while under the influence of alcohol or
drugs.
16. Do not engage the self-propelled mechanism on units so
equipped while starting engine.
17. The blade control handle is a safety device. Never attempt
to bypass its operation. Doing so makes the safety device
inoperative and may result in personal injury through contact with
the rotating blade. The blade control handle must operate easily
in both directions and automatically return to the disengaged
position when released.
18. Never operate the mower in wet grass. Always be sure of your
footing. A slip and fall can cause serious personal injury. If you
feel you are losing your footing, release the blade control handle
immediately and the blade will stop rotating within three seconds.
19. Mow only in daylight or in good artificial light. Walk, never run.
20. Stop the blade when crossing gravel drives, walks or roads.
21. If the equipment should start to vibrate abnormally, stop the
engine and check immediately for the cause. Vibration is gener-
ally a warning of trouble.
22. Shut the engine off and wait until the blade comes to a complete
stop before removing the grass catcher or unclogging the chute.
The cutting blade continues to rotate for a few seconds after the
engine is shut off. Never place any part of the body in the blade
area until you are sure the blade has stopped rotating.
23. Never operate mower without proper trail shield, discharge cover,
grass catcher, blade control handle or other safety protective
devices in place and working. Never operate mower with
damaged safety devices. Failure to do so, can result in personal
injury.
24. Muffler and engine become hot and can cause a burn. Do not
touch.
25. Never attempt to make a wheel or cutting height adjustment while
the engine is running.
26. Only use parts and accessories made for this machine by the
manufacturer. Failure to do so can result in personal injury.
27. When starting engine, pull cord slowly until resistance is felt, then
pull rapidly. Rapid retraction of starter cord (kickback) will pull
hand and arm toward engine faster than you can let go. Broken
bones, fractures, bruises or sprains could result.
28. If situations occur which are not covered in this manual, use care
and good judgment. Call customer assistance for the name of
your nearest servicing dealer.
Slope Operation
Slopes are a major factor related to slip and fall accidents which can
result in severe injury. Operation on slopes requires extra caution.
If you feel uneasy on a slope, do not mow it. For your safety, use
the slope gauge included as part of this manual to measure slopes
before operating this unit on a sloped or hilly area. If the slope is
greater than 15 degrees, do not mow it.
Do:
1. Mow across the face of slopes; never up and down. Exercise
extreme caution when changing direction on slopes.
2. Watch for holes, ruts, rocks, hidden objects, or bumps which can
cause you to slip or trip. Tall grass can hide obstacles.
WARNING: Engine Exhaust, some of its constituents, and certain vehicle components contain
or emit chemicals known to the State of California to cause cancer and birth defects or other
reproductive harm.

Service
Safe Handling Of Gasoline:
1. To avoid personal injury or property damage use extreme care
in handling gasoline. Gasoline is extremely flammable and the
vapors are explosive. Serious personal injury can occur when
gasoline is spilled on yourself or your clothes which can ignite.
Wash your skin and change clothes immediately.
2. Use only an approved gasoline container.
3. Never fill containers inside a vehicle or on a truck or trailer bed
with a plastic liner. Always place containers on the ground away
from your vehicle before filling.
4. Remove gas-powered equipment from the truck or trailer and
refuel it on the ground. If this is not possible, then refuel such
equipment on a trailer with a portable container, rather than from
a gasoline dispenser nozzle.
5. Keep the nozzle in contact with the rim of the fuel tank or
container opening at all times until fueling is complete. Do not
use a nozzle lock-open device.
6 Extinguish all cigarettes, cigars, pipes and other sources of
ignition.
7. Never fuel machine indoors because flammable vapors will
accumulate in the area.
8. Never remove gas cap or add fuel while the engine is hot or run-
ning. Allow engine to cool at least two minutes before refueling.
9. Never over fill fuel tank. Fill tank to no more than ½ inch below
bottom of filler neck to provide for fuel expansion.
10. Replace gasoline cap and tighten securely.
11. If gasoline is spilled, wipe it off the engine and equipment. Move
unit to another area. Wait 5 minutes before starting the engine.
12. Never store the machine or fuel container near an open flame,
spark or pilot light as on a water heater, space heater, furnace,
clothes dryer or other gas appliances.
13. To reduce fire hazard, keep mower free of grass, leaves, or
other debris build-up. Clean up oil or fuel spillage and remove
any fuel soaked debris.
14. Allow a mower to cool at least 5 minutes before storing.
General Service:
1. Never run an engine indoors or in a poorly ventilated area.
Engine exhaust contains carbon monoxide, an odorless and
deadly gas.
2. Before cleaning, repairing, or inspecting, make certain the
blade and all moving parts have stopped. Disconnect the spark
plug wire and ground against the engine to prevent unintended
starting.
3. Check the blade and engine mounting bolts at frequent
intervals for proper tightness. Also, visually inspect blade for
damage (e.g., bent, cracked, worn) Replace blade with the
original equipment manufacture’s (O.E.M.) blade only, listed
in this manual. “Use of parts which do not meet the original
equipment specifications may lead to improper performance
and compromise safety!”
4. Mower blades are sharp and can cut. Wrap the blade or wear
gloves, and use extra caution when servicing them.
5. Keep all nuts, bolts, and screws tight to be sure the equipment
is in safe working condition.
6. Never tamper with safety devices. Check their proper operation
regularly.
7. After striking a foreign object, stop the engine, disconnect the
spark plug wire and ground against the engine. Thoroughly
inspect the mower for any damage. Repair the damage before
starting and operating the mower.
8. Never attempt to make a wheel or cutting height adjustment
while the engine is running.
9. Grass catcher components, discharge cover, and trail shield
are subject to wear and damage which could expose moving
parts or allow objects to be thrown. For safety protection,
frequently check components and replace immediately with
original equipment manufacturer’s (O.E.M.) parts only, listed
in this manual. “Use of parts which do not meet the original
equipment specifications may lead to improper performance
and compromise safety!”
10. Do not change the engine governor setting or overspeed the
engine. The governor controls the maximum safe operating
speed of the engine.
11. Check fuel line, tank, cap, and fittings frequently for cracks or
leaks. Replace if necessary.
12. Do not crank engine with spark plug removed.
13. Maintain or replace safety labels, as necessary.
14. Observe proper disposal laws and regulations. Improper
disposal of fluids and materials can harm the environment.
Do not modify engine
To avoid serious injury or death, do not modify engine in any way.
Tampering with the governor setting can lead to a runaway engine
and cause it to operate at unsafe speeds. Never tamper with
factory setting of engine governor.

Using Your Lawn Mower
Be sure the lawn is clear of stones, sticks, wire, or other
objects which could damage the lawn mower or the
engine. Such objects could be accidently thrown by the
mower in any direction and cause serious personal injury
to the operator and others.
WARNING: If you strike a foreign
object, stop the engine. Remove
wire from the spark plug, thor-
oughly inspect the mower for any
damage, and repair the damage
before restarting and operating
the mower. Extensive vibration
of the mower during operation is
an indication of damage. The unit
should be promptly inspected
and repaired.
Operating Tips
1. For best results and effective mulching, do not cut wet
grass.
2. New grass, thick grass, or wet grass may require a
narrower cut.
3. For a healthier lawn, never cut off more than one-third
of the total length of the grass.
4. Your lawn should be cut in the fall as long as there
is growth.
5. Adjust ground speed according to condition of lawn.
6. If the grass has been allowed to grow in excess of 4
inches, mulching is not recommended. Mow using
the side discharge to reduce the grass height to 3-1/4
inches or less before mulching.

Figure 10
General Recommendations
1. Always observe safety rules when performing
any maintenance.
2. The warranty on this lawn mower does not cover
items that have been subjected to operator abuse
or negligence. To receive full value from warranty,
operator must maintain the lawn mower as
instructed here.
3. Changing of engine-governed speed will void
engine warranty.
4. All adjustments should be checked at least once
each season.
5. Periodically check all fasteners and make sure these
are tight.
Lubrication
1. Lubricate the pivot points on the blade control handle
at least once a season with light oil. The blade
control must operate freely in both directions. See
Figure 10.
2. If your mower is equipped with ball bearing wheels,
lubricate at least once a season with a light oil, all
other types 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 automotive oil.
3. Lubricate the torsion spring and pivot point periodi-
cally with light oil to prevent rust. See Figure 10.
4. Follow the accompanying engine manual for lubrica-
tion schedule and instruction.
Lubricate these
points before
reassembly
Engine
1. Refer to the separate engine manual for engine
maintenance instructions.
2. Maintain engine oil as instructed in the separate
engine manual packed with your unit. Read and follow
instructions carefully.
3. Under normal conditions service air cleaner as
instructed in the separate engine manual packed with
your unit. Clean every few hours under extremely
dusty conditions. Poor engine performance and
flooding usually indicates that the air cleaner should be
serviced.
4. The spark plug should be cleaned and the gap reset
once a season. Spark plug replacement is recom-
mended at the start of each mowing season; check
engine manual for correct plug type and gap specifica-
tions.
NOTE: This spark ignition system meets all require-
ments of the Canadian Interference-Causing Equipment
Regulations.
5. 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.
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 prevent proper
mulching.
The deck may be cleaned by tilting the mower and scrap-
ing clean with a suitable tool (make certain the spark plug
wire is disconnected).
Blade Care
WARNING: When removing the
cutting blade for sharpening or
replacement, protect your hands
with a pair of heavy gloves or use
a heavy rag to hold the blade.
Periodically inspect the blade adapter for cracks, especial-
ly if you strike a foreign object. Replace when necessary.
Follow the steps below for blade service:
1. Disconnect spark plug wire from spark plug.
2. Tip mower as specified in separate engine manual. If
it does not specify turn mower on its side making sure
that the air filter and the carburetor are up.
3. Remove the bolt and the blade bell support which
hold the blade and the blade adapter to the engine
crankshaft. See Figure 11.
We do not recommend
the use of pressure
washers or garden
hose to clean your
unit. These may cause
damage to electrical
components, spindles,
pulleys, bearings, or
the engine. The use
of water will result in
shortened life and
reduce serviceability.

WARNING
When removing
the cutting blade
for sharpening or
replacement, protect
your hands with a
pair of heavy gloves
or use a heavy rag to
hold the blade.
An unbalanced blade
will cause excessive
vibration when rotat-
ing at high speeds. It
may cause damage
to mower, and could
break causing per-
sonal injury.
Figure 11
4. Remove blade and adapter from the crankshaft.
5. The blade may be resharpened by removing it and
either grinding or filing the cutting edge keeping as
close to the original bevel as possible. Do not attempt
to sharpen the blade while it is still on the mower.
6. It is extremely important that each cutting edge
receives an equal amount of grinding to prevent an
unbalanced blade.
NOTE: Improper blade balance will result in excessive
vibration causing eventual damage to the engine and
mower. Be sure to carefully balance blade after sharpen-
ing. Possible damage resulting from blade unbalance
condition is not the responsibility of the manufacturer.
NOTE: Always remove blade from the adapter for testing
balance.
7. The blade can be tested for balance by balancing it
on a round shaft screwdriver. Remove metal from the
heavy side until it balances evenly.
8. 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.
9. Install the blade adapter on the crankshaft with the
“star” away from the engine. See Figure 11. Place
the blade with the side marked “bottom” (or with part
number) facing away from the adapter. Align the

Off-Season Storage
The following steps should be taken to prepare your lawn
mower for storage.
1. Clean and lubricate mower thoroughly as described in
the lubrication instructions.
2. We do not recommend the use of a pressure washer
or garden hose to clean your unit.
3. Refer to engine manual for correct engine
storage instructions.
4. Coat mower’s cutting blade with chassis grease to
prevent rusting.
5. 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
a poorly ventilated 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 of your lawn mower before storage.
