SECTION 1: IMPORTANT SAFE OPERATION PRACTICES
WARNING: This symbol points out important safety instructions which, if not followed, could
endanger the personal safety and/or property of yourself and others. Read and follow all instructions in
this manual before attempting to operate this machine. Failure to comply with these instructions may
result in personal injury. When you see this symbol - heed its warning.
WARNING: Engine Exhaust, some of its constituents, and certain vehicle components contain or
emit chemicals known to State of California to cause cancer and birth defects or other reproductive
harm.
DANGER:This machine was built to be operated according to the rules for safe operation in this
manual. As with any type of power equipment, carelessness or error on the part of the operator can
result in serious injury. This machine is capable of amputating hands and feet and throwing objects.
Failure to observe the following safety instructions could result in serious injury or death.
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. Be completely familiar with the controls and
the proper use of this machine before operating it. Keep this
manual in a safe place for future and regular reference and for
ordering replacement parts.
2. 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.
3. 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 parent. Only responsible individuals who are familiar with
these rules of safe operation should be allowed to use this
machine.
4. 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.
Plan your mowing pattern to avoid discharge of material toward
roads, sidewalks, bystanders and the like. Also, avoid
discharging material against a wall or obstruction which may
cause discharged material to ricochet back toward the operator.
5. 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.
6. 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.
7. 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.
8. Do not put hands or feet near rotating parts or under the cutting
deck. Contact with the blade can amputate hands and feet.
9. A missing or damaged discharge cover can cause blade contact
or thrown object injuries.
10. 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.
11. 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.
12. Do not operate the mower while under the influence of alcohol
or drugs.
13. Do not engage the self-propelled mechanism on units so
equipped while starting engine.
14. 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.
15. 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.
16. Mow only in daylight or in good artificial light. Walk, never run.
Stop the blade when crossing gravel drives, walks or roads.
17. If the equipment should start to vibrate abnormally, stop the
engine and check immediately for the cause. Vibration is
generally a warning of trouble.
18. 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.
19. 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.
20. Muffler and engine become hot and can cause a burn. Do not
touch.
21. Only use parts and accessories made for this machine by the
manufacturer. Failure to do so can result in personal injury.
22. 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.
3. Always be sure of your footing. A slip and fall can cause serious
personal injury. If you feel you are losing your balance, release
the blade control handle immediately, and the blade will stop
rotating within 3 seconds.
Do Not:
1. Do not mow near drop-offs, ditches or embankments, you could
lose your footing or balance.
2. Do not mow slopes greater than 15 degrees as shown on the
slope gauge.
3. Do not mow on wet grass. Unstable footing could cause slipping.
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 mowing
activity. They do not understand the dangers. 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 if a child enters the area.
3. Before and while moving backwards, look behind and down for
small children.
4. Use extreme care when approaching blind corners, doorways,
shrubs, trees, or other objects that may obscure your vision of a
child who may run into the mower.
5. Keep children away from hot or running engines. They can suffer
burns from a hot muffler.
6. Never allow children under 14 years old to operate a power
mower. Children 14 years old and over should read and
understand the operation instructions and safety rules in this
manual and should be trained and supervised by a parent.
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.
2. Wash your skin and change clothes immediately.
3. Use only an approved gasoline container.
4. 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.
5. 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.
6. 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.
7. Extinguish all cigarettes, cigars, pipes and other sources of
ignition.
8. Never fuel machine indoors because flammable vapors will
accumulate in the area.
9. Never remove gas cap or add fuel while the engine is hot or
running. Allow engine to cool at least two minutes before
refueling.
10. Never over fill fuel tank. Fill tank to no more than ½ inch below
bottom of filler neck to provide for fuel expansion.
11. Replace gasoline cap and tighten securely.
12. If gasoline is spilled, wipe it off the engine and equipment. Move
unit to another area. Wait 5 minutes before starting the engine.
13. 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.
14. 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.
15. 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. Maintain or replace safety labels, as necessary.
12. Observe proper disposal laws and regulations. Improper
disposal of fluids and materials can harm the environment.

Periodically inspect the blade adapter for cracks, especially if you strike a foreign object. Replace when necessary.
Follow the steps below for blade service:
• Disconnect spark plug wire from spark plug.
• 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.
• Remove the bolt and the blade bell support which
hold the blade and the blade adapter to the engine
crankshaft. See Figure 14.
• Remove blade and adapter from the crankshaft.
• 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.
•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
sharpening. Possible damage resulting from blade
unbalance condition is not the responsibility of the manufacturer.
NOTE: Always remove blade from the adapter for testing balance.
• 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.
• 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.
• Install the blade adapter on the crankshaft with the “star” away from the engine. See Figure 14. 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 holes of the blade and insert the hex bolt.
WARNING: Never tip the mower more than 90 degrees in any directions and do not leave the mower
tipped for any length of time. Oil can drain into the upper part of the engine causing a starting problem.
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.

• Tighten the hex bolt to the torque listed below:
Blade Mounting Torque
Center Bolt 450 in. lb. min., 600 in.lb. max.
To insure safe operation of your unit, ALL nuts and bolts must be checked periodically for correct tightness.
NOTE: Cutting grass in sandy soil condition causes abrasive wear to the blade.
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.
IMPORTANT:
We do not recommend the use of a pressure washer or garden hose to clean your unit.
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 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.
NOTE: Be careful not to bend or kink cables.
NOTE: If the starter rope becomes disconnected from rope guide on handle, disconnect and ground the spark plug
wire. Depress the blade control handle and pull the starter rope out from engine slowly. Slip the starter rope into the
rope guide bolt on handle.
