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. This machine 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 of age to operate this
machine. Children 14 and over should read and understand
the instructions and safe operation practices in this manual
and on the machine and should be trained and supervised
by an 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 discharging 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 operator zone behind handles and keep children,
bystanders, helpers and pets at least 75 feet from mower
while it is in operation. Stop machine if anyone enters 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 light­weight (e.g. canvas) shoes.

11. Do not put hands or feet near rotating parts or under the
cutting deck. Contact with blade can amputate fingers,
hands, toes and feet.

3

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 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 machines
so equipped while starting engine.

17. The blade control 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 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 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 generally 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 blade control is released.
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 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
injur y.

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 judgement. Contact Customer Support
for assistance or the name of the nearest service 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 machine 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 three (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 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 of age to operate this
machine. Children 14 and over should read and understand
the instructions and safe operation practices in this manual
and on the machine and be trained and supervised by an
adult.

4 Section 2 — important Safe operation practiceS

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 engine is hot or
running. Allow engine to cool at least two minutes before
refueling.

9. Never over fill fuel tank. Fill tank to no more than 1 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 machine to another area. Wait 5 minutes before
starting 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 machine free of grass, leaves,
or other debris build-up. Clean up oil or fuel spillage and
remove any fuel soaked debris.

14. Allow machine 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’s governor setting or over-speed
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 and instruction labels, as
necessar y.

14. Observe proper disposal laws and regulations. Improper
disposal of fluids and materials can harm the environment.

15. According to the Consumer Products Safety Commission
(CPSC) and the U.S. Environmental Protection Agency (EPA),
this product has an Average Useful Life of seven (7) years,
or 140 hours of operation. At the end of the Average Useful
Life have the machine inspected annually by an authorized
service dealer to ensure that all mechanical and safety
systems are working properly and not worn excessively.
Failure to do so can result in accidents, injuries or death.

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.

any type of maintenance on your machine.

Lubrication

1. Lubricate pivot points on the blade and drive controls
at least once a season with light oil. These controls must
operate freely in both directions. See Figure 6-1.

2. The transmission is pre-lubricated and sealed at the factory
and does not require lubrication.

3. Follow the accompanying engine manual for lubrication
schedule and instruction for engine lubrication.

Deck Care

Clean underside of the mower deck after each use to prevent
build-up of grass clippings or other debris. Follow steps below
for this job.

1. Disconnect spark plug wire. Drain gasoline from lawn
mower or place a piece of plastic under the gas cap.

2. Tip mower so that it rests on the housing. Keep the side
with the air cleaner facing up. Hold mower firmly.

WARNING: Never tip the mower more than 90º in

any direction 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.

3. Scrape and clean the underside of the deck with a suitable
tool.

4. Put the mower back on its wheels on the ground. If you had
put plastic under the gas cap earlier, make sure to remove it
now.
