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!
Your Responsibility
Restrict the use
of this power machine
to persons who read,
understand
and follow the warnings
and instructions
in this manual
and on the machine.
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.
Children
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 cutting
deck. Contact with 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 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 good artificial light. Walk, never run.
17.Stop the blade when crossing gravel drives, walks or roads.
18.If the equipment should start to vibrate abnormally, stop the
engine and check immediately for the cause. Vibration is
generally a warning of trouble.
Tragic accidents can occur if operator is not alert to presence
of children. Children are often attracted to mower and 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 old to operate a power
mower. Children 14 years old and over should read and
understand operation instructions and safety rules in this
manual and should be trained and supervised by a parent.
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 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.

19.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.
20.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.
21.Muffler and engine become hot and can cause a burn. Do
not touch.
22.Only use parts and accessories made for this machine by
manufacturer. Failure to do so can result in personal injury.
23.If situations occur which are not covered in this manual,
use care and good judgment. Contact your dealer for
assistance.
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.
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 indoor 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 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
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.

Safe
Operation
Practices
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 over-rev 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.

Maintaining
Your
Engine
Storage
Engines stored over 30 days need to be drained of fuel
to prevent deterioration and gum from forming in fuel
system or on essential carburetor parts. If the gasoline in
your engine deteriorates during storage, you may need to
have the carburetor, and other fuel system components,
serviced or replaced.
1. Remove all fuel from tank by running engine until it
stops from lack of fuel.
Electrode
2. Change oil. See Oil Change section.
0.030 in.
Figure 10-4: Measure the plug gap with a feeler gauge.
3. Measure the plug gap with a feeler gauge. Correct
as necessary by bending side electrode. See Figure
10-4. The gap should be set to 0.030 in.
WARNING
Accumulation of
debris around muffler
could cause a fire.
Inspect and clean
before every use.
4. Clean grass and debris from around engine, under
finger guard, and under, around and behind muffler.
Touch up any damaged paint, and coat other areas
that may rust with a light film of oil.
4. Check that the spark plug washer is in good condition and thread the spark plug in by hand to prevent
cross-threading.
5. Store in a clean, dry and well ventilated area away from
any appliance that operates with a flame or pilot light,
such as a furnace, water heater, or clothes dryer. Also
avoid any area with a spark producing electric motor,
or where power tools are operated.
5. After the spark plug is seated, tighten with a spark
plug wrench to compress the washer.
6. If possible, also avoid storage areas with high humidity,
because that promotes rust and corrosion.
NOTE: When installing a new spark plug, tighten 1/2
turn after the spark plug seats to compress the washer.
When reinstalling a used spark plug, tighten 1/8-1/4 turn
after the spark plug seats to compress the washer.
IMPORTANT: The spark plug must be securely tightened. An improperly tightened spark plug can become
very hot and may damage the engine.
IMPORTANT: Do not
spray engine with water
to clean because water
could contaminate fuel.
Using a garden hose
or pressure washing
equipment can also
force water into the
air cleaner or muffler
opening. Water in the
air cleaner will soak
the paper element,
and water that passes
through the element
or muffler can enter
the cylinder, causing
damage.
3. Remove spark plug and pour about 1/2 an ounce of
engine oil into cylinder. Replace spark plug and crank
slowly to distribute oil.
Clean Engine
If the engine has been running, allow it to cool for at
least half an hour before cleaning. Periodically remove
grass and dirt build-up from engine. Clean finger guard
and around muffler. Clean with a brush or compressed
air.
7. Keep the engine level in storage. Tilting can cause fuel
or oil leakage.
Removing From Storage
1. Check your engine as described in the Pre-Operation
Check section of this manual.
2. If the fuel was drained during storage preparation, fill
the tank with fresh gasoline. If you keep a container
of gasoline for refueling, make certain it contains only
fresh fuel. Gasoline oxidizes and deteriorates over
time, causing hard starting.
3. If the cylinder was coated with oil during storage
preparation, the engine will smoke briefly at startup.
This is normal.
IMPORTANT: Do not spray engine with water to clean
because water could contaminate fuel. Using a garden
hose or pressure washing equipment can also force
water into the air cleaner or muffler opening. Water in
the air cleaner will soak the paper element, and water
that passes through the element or muffler can enter the
cylinder, causing damage.
WARNING: Accumulation of debris
around muffler could cause a fire.
Inspect and clean before every use.

Emission Control System Warranty Statement
(Owner’s Defect Warranty Rights and Obligations)
The U. S. EPA and MTD are pleased to explain the emissions control system warranty on your model year 2005 and later small off-road engine.
New small off-road engines must be designed, built and equipped to meet the stringent anti-smog standards. MTD must warranty the emission
control system on your engine for the period of time listed below, provided there has been no abuse, neglect or improper maintenance of your small
off-road engine.
Your emission control system may include parts such as the carburetor, air cleaner, ignition system, exhaust system, and other associated emission-related components.
Where a warrantable condition exists, MTD will repair your small off-road engine at no cost to your including diagnosis, parts and labor.
MANUFACTURER’S WARRANTY COVERAGE:
This emissions control system is warranted for two years. If any emission-related part on your engine is defective, the part will be repaired or
replaced by MTD.
OWNER’S WARRANTY RESPONSIBILITIES:
As the small off-road engine owner, you are responsible for the performance of the required maintenance listed in your Owner’s Manual. MTD
recommends that you retain all your receipts covering maintenances on your small off-road engine, but MTD can not deny warranty solely for the
lack of receipts or for your failure to ensure the performance to all scheduled maintenance.
As the small off-road engine owner, you should however be aware that MTD may deny your warranty coverage if your small off-road engine or part
has failed due to abuse, neglect, improper maintenance or unapproved modifications.
You are responsible for presenting your small off-road engine to an Authorized MTD Service Dealer as soon as a problem exists. The warranted
repairs should be completed in a reasonable amount of time, not to exceed 30 days.
If you have any questions regarding your warranty rights and responsibilities, you should contact a MTD Service Representative at 1-800-800-7310
and address is MTD LLC, P.O. Box 361131, Cleveland OH, 44136-0019.
Defects Warranty Requirements for 1995 and Later Small Off-Road Engines:
This section applies to 1995 and later small off-road engines. The warranty period begins on the date the engine or equipment is delivered to an
ultimate purchaser.
(a) General Emissions Warranty Coverage
MTD must warrant to the ultimate purchaser and each subsequent purchaser that the engine is:
(1) Designed, built, and equipped so as to conform with all applicable regulations adopted by the Air Resources Board pursuant to its authority in
Chapters 1 and 2,Part 5, Division 26 of the Health and Safety Code; and
(2) Free from defects in materials and workmanship that cause the failure of a warranted part to be identical in all material respects to the part as
described in the engine manufacturer’s application for certification for a period of two years.
(b) The warranty on emissions-related parts will be interpreted as follows:
(1) Any warranted part that is not scheduled for replacement as required maintenance in the written instructions required by Subsection (c)
must be warranted for the warranty period defined in Subsection (a)(2). If any such part fails during the period of warranty coverage, it must be
repaired or replaced by MTD according to Subsection (4) below. Any such part repaired or replaced under the warranty must be warranted for
the remaining warranty period.
(2) Any warranted part that is scheduled only for regular inspection in the written instructions required by Subsection (c) must be warranted for
the warranty period defined in Subsection (a)(2). A statement in such written instructions to the effect of “repair or replace as necessary” will
not reduce the period of warranty coverage. Any such part repaired or replaced under warranty must be warranted for the remaining warranty
period.
(3) Any warranted part that which is scheduled for replacement as required maintenance in the written instructions required by Subsection (c)
must be warranted for the period of time prior to the first scheduled replacement point for that part. If the part fails prior to the first scheduled
replacement, the part must be repaired or replaced by MTD according to Subsection (4) below. Any such part repaired or replaced under
warranty must be warranted for the remainder of the period prior to the first scheduled replacement point for the part.
(4) Repair or replacement of any warranted part under the warranty provisions of this article must be performed at no charge to the owner at a
warranty station.
(5) Notwithstanding the provisions of Subsection (4) above, warranty services or repairs must be provided at all MTD distribution centers that
are franchised to service the subject engines.
(6) The owner must not be charged for diagnostic labor that leads to the determination that a warranted part is in fact defective, provided that
such diagnostic work is performed at a warranty station.

(7) The engine manufacturer is liable for damages to other engine components proximately caused by a failure under warranty of any warranted
part.
(8) Throughout the engine’s warranty period defined in Subsection (a)(2), MTD will maintain a supply of warranted parts sufficient to meet the
expected demand for such parts.
(9) Any replacement part may be used in the performance of any warranty maintenance or repairs and must be provided without charge to the
owner. Such use will not reduce the warranty obligations of MTD.
(10) Add-on or modified parts that are not exempted by the Air Resources Board may not be used. The use of any non-exempted add-on or
modified parts shall be grounds for disallowing a warranty claim made in accordance with this article. The engine manufacturer shall not be
liable under this article to warrant failures of warranted parts caused by the use of non-exempted add-on or modified part.
(c) MTD will include a copy of the following emission warranty parts list with each new engine, using those portions of the list applicable to the
engine.

for a period of two (2) years commencing on the date of original purchase
and will, at its option, repair or replace, free of charge, any part found to
be defective in materials or workmanship. This limited warranty shall only
apply if this product has been operated and maintained in accordance
with the Operator’s Manual furnished with the product, and has not been
subject to misuse, abuse, commercial use, neglect, accident, improper
maintenance, alteration, vandalism, theft, fire, water, or damage because
of other peril or natural disaster. Damage resulting from the installation or
use of any part, accessory or attachment not approved by MTD for use
with the product(s) covered by this manual will void your warranty as to
any resulting damage.

workmanship for a period of thirty (30) days from the date of purchase.
Normal wear parts include, but are not limited to items such as belts,
blades, blade adapters, grass bags, wheels, engine oil, air filters, and
spark plugs.
HOW TO OBTAIN SERVICE: Warranty service is available, WITH
PROOF OF PURCHASE, through your local authorized service dealer. To
locate the dealer in your area, check your Yellow Pages, or contact MTD

or retailer, with respect to any product, shall bind MTD. During the
period of the warranty, the exclusive remedy is repair or replacement

limitation, expenses incurred for substitute or replacement lawn care

consequential damages, or limitations on how long an implied warranty
lasts, so the above exclusions or limitations may not apply to you.

purchase price of the product sold. Alteration of safety features of the
product shall void this warranty. You assume the risk and liability for
loss, damage, or injury to you and your property and/or to others and their

purchaser or to the person for whom it was purchased as a gift.
