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.

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

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 entiret y 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.

6. Always wear safety glasses or safety goggles during opera

tion 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. Shir ts 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.

19. Shut the engine off and wait until the blade comes to a

complete stop before removing the grass catcher or unclog-

ging 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.

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 equip ment 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, discon nect 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 adjust

ment while the engine is running.

9. Grass catcher components, discharge cover, and trail

shield are subject to wear and damage which could

expose moving par ts or allow objects to be thrown. For

safety protection, frequently check components and re-

place immediately with original equipment manufacturer’s

(O.E.M.) par ts 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 gover nor setting or over-rev the engine. The governor controls the maximum safe operating speed of the engine.

11. Maintain or replace safety labels, as necessar y.

12. Observe proper disposal laws and regulations. Improper

disposal of fluids and materials can harm the environment.

Gasoline and its vapors are extremely flammable and explosive. Fire or explosion can cause severe burns or death. If gasoline is spilled on yourself or your clothes, wash your skin and change clothes immediately.

• When adding fuel, turn engine OFF and let engine cool at least 2 minutes before removing gas cap.

• Fill fuel tank outdoors or in well ventilated area.

• Use only an approved gasoline container.

• 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.

• If possible, 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.

• 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.

• Do not overfill fuel tank. Fill tank to approximately 2 cm below lowest portion of neck to allow for fuel expansion.

• Keep gasoline away from sparks, open flames, pilot lights, heat, and other ignition sources.

• Never fuel equipment indoors because flammable vapors will accumulate in the area.

• Extinguish all cigarettes, cigars, pipes, and other sources of ignition.

• Check fuel line, tank, cap, and fittings frequently for cracks or leaks. Replace if necessary.

• When starting engine, make sure spark plug, muffler, fuel cap and air cleaner are in place.

• Do not crank engine with spark plug removed.

• If fuel spills, wait until it evaporates before starting engine.

• When operating equipment, do not tip engine or equipment at angle which causes gasoline to spill.

• Do not choke carburetor to stop engine.

• When transporting equipment, transport with fuel tank EMPTY.

• When storing gasoline or equipment with fuel in tank, store away from furnaces, stoves, water heaters or other appliances that have pilot light or other ignition source because they can ignite gasoline vapors.

Starting engine creates sparking. Sparking can ignite nearby flammable gases. Explosion and fire could result.

• If there is a natural or LP gas leakage in area, do not start engine.

• Do not use pressurized starting fluids because vapors are flammable.

Engines give off carbon monoxide, an odorless, colorless, poisonous gas. Breathing carbon monoxide can cause nausea, fainting, or death.

• Start and run engine outdoors.

NOTE: Please dispose of used motor oil in a manner that is compatible with the environment. We suggest you take it in a sealed container to your local service station for reclamation. Do not throw it in the trash or pour it on the ground.

Air Cleaner Service

A dirty air cleaner will restrict air flow to the carburetor. To prevent carburetor malfunction, service the air cleaner regularly. Service more frequently when operating the engine in extremely dusty areas.

WARNING: Never use gasoline or low flash point solvents for cleaning the air cleaner element. A fire or explosion could result.

IMPORTANT: Never run the engine without the air

cleaner. Rapid engine wear will result.

1. Remove the wing bolt and the air cleaner cover. Remove the elements and separate them. See Figure 10-2. Carefully check both elements for holes or tears and replace if damaged.

2. Foam element: Wash the element in a solution of household detergent and warm water, then rinse thoroughly, or wash in nonflammable or high flash point solvent. Allow the element to dry thoroughly. Soak the element in clean engine oil and squeeze out the excess oil. The engine will smoke during initial start-up if too much oil is left in the foam.

3. Paper element: Tap the element lightly several times on a hard surface to remove excess dirt, or blow compressed air through the filter from the inside out. Never try to brush the dirt off; brushing will force dirt into the fibers. Replace the paper element if it is excessively dirty.

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.

2. Change oil. See Oil Change section.

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.

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.

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.

6. If possible, also avoid storage areas with high humidity, because that promotes rust and corrosion.

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.

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.

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

Normal wear parts are warranted to be free from defects in material and 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 LLC at P.O. Box 361131, Cleveland, Ohio 44136-0019, or call 1-800-8007310 or log on to our Web site at www.mtdproducts.com.

a. Log splitter pumps, valves, and cylinders have a separate one

year warranty.

sharpening, tune-ups, brake adjustments, clutch adjustments, deck adjustments, and normal deterioration of the exterior finish due to use or exposure.
