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.  
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.  
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.  
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.

not recommend the use  
of pressure washers or  
a garden hose to clean  
your unit. These may  
cause damage to electric  
components, spindles,  
pulleys, bearings, or the  
engine. The use of water  
will result in shortened life  
and reduce serviceability.  
General Recommendations  
Always observe safety rules when performing  
any maintenance.  
1. Maintain oil level.  
2. Service air cleaner every 25 hours under normal  
conditions. Clean every few hours under extremely  
dusty conditions.  
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. Clean spark plug and reset the gap once a season.  
4. Clean engine regularly with a cloth or brush. Keep the  
cooling system (blower housing area) clean to permit  
proper air circulation. Remove all grass, dirt, and  
combustible debris from muffler area.  
Changing of engine-governed speed will void  
engine warranty.  
All adjustments should be checked at least once  
each season.  
Replacing Rear Flap  
1. Lift up rear door.  
Periodically check all fasteners and make sure these  
are tight.  
2. Bend (bow) the rear flap inward on each side to  
release tabs from the holes in the handle mounting  
brackets, Figure 5-2.  
WARNING: Always stop engine,  
disconnect spark plug, and ground  
against engine before servicing the  
unit.  
3. Replace with new flap by bending the rear flap and  
sliding into place.

and baffle, first around the transmission pulley and  
then the engine pulley.  
Maintaining  
Your Lawn  
Mower  
Coat mower’s cutting blade with chassis grease to  
prevent rusting.  
Store mower in a dry, clean area. Do not store next to  
corrosive materials, such as fertilizer.  
NOTE: Make certain that belt is seated correctly and  
that it is riding smoothly on the engine pulley and is not  
pinched between the lower and upper pulley halves.  
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.

careful not to touch the muffler.  
2. Visually inspect the spark plug. Discard the spark plug  
if there is apparent wear, or if the insulator is cracked  
or chipped. Clean the spark plug with a wire brush if it  
is to be reused.

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.

Maintaining  
Your  
1. Remove all fuel from tank by running engine until it  
stops from lack of fuel.  
2. Change oil. See Oil Change section.  
Engine  
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.  
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, Figure 10-4.  
The gap should be set to 0.030 in.  
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.  
4. Check that the spark plug washer is in good condi-  
tion and thread the spark plug in by hand to prevent  
cross-threading.  
WARNING  
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.  
Accumulation of debris  
around muffler could  
cause a fire. Inspect and  
clean before every use.  
7. Keep the engine level in storage. Tilting can cause fuel  
or oil leakage.  
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.  
Removing From Storage  
1. Check your engine as described in the Pre-Operation  
Check section of this manual.  
IMPORTANT: The spark plug must be securely tight-  
ened. An improperly tightened spark plug can become  
very hot and may damage the engine.  
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.  
Spark Plug Part Number: 951-10292  
IMPORTANT: Do not  
Clean Engine  
3. If the cylinder was coated with oil during storage  
preparation, the engine will smoke briefly at startup.  
This is normal.  
spray engine with water  
to clean because water  
could contaminate fuel.  
Using a garden hose  
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.  
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.

Emission Control System Warranty Statement  
(Owner’s Defect Warranty Rights and Obligations)  
EMISSION CONTROL SYSTEM COVERAGE IS APPLICABLE TO CERTIFIED ENGINES PURCHASED IN CALIFORNIA IN 2005 AND THERE-  
AFTER, WHICH ARE USED IN CALIFORNIA, AND TO CERTIFIED MODEL YEAR 2005 AND LATER ENGINES WHICH ARE PURCHASED AND  
USED ELSEWHERE IN THE UNITED STATES.  
California and elsewhere in the United States Emission Control Defects Warranty Coverage  
The California Air Resources Board (CARB), 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. In California, new small off-road engines must be designed, built and equipped to meet the States anti-smog  
standards. Elsewhere in the United States, new non-road, spark-ignition engines certified for model 2005 and later, must meet similar standards set  
forth by the U. S. EPA. 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, fuel-injection system, the ignition system, and catalytic converter, fuel  
tanks, fuel lines, fuel caps, valves, canisters, filters, vapor hoses, clamps, connectors, 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.

(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.
