SAFETY INSTRUCTIONS  
If the equipment should start to vibrate abnormally, stop the engine and  
check immediately for the cause. Vibration is generally a warning of trouble.  
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.  
Shut the engine off and wait until the blade comes to a complete stop before  
removing the grass Bagger 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.  
Keep children out of the mowing area and under watchful care of a  
responsible adult other than the operator.  
Never operate mower without proper trail shield, discharge cover, grass  
Bagger, 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.  
Be alert and turn mower off if a child enters the area.  
Before and while moving backwards, look behind and down for small  
children.  
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.  
Muffler and engine become hot and can cause a burn. Do not touch.  
Never attempt to make a wheel or cutting height adjustment while the  
engine is running.  
Keep children away from hot or running engines. They can suffer burns from  
a hot muffler.  
Only use parts and accessories made for this machine by the manufacturer as  
listed in the Parts pages of this Operator’s Manual. Failure to do so can result  
in personal injury.  
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.  
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.  
SERVICE  
Safe Handling of Gasoline:  
If situations occur which are not covered in this manual, use care and good  
judgement.  
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.  
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. The machine is heavy and can  
speed up when going downhill. Be prepared to maintain control of the machine.  
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.  
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.  
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.  
Do:  
Mow across the face of slopes; never up and down to avoid loss of control.  
Exercise extreme caution when changing direction on slopes; turn uphill not  
down.  
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.  
Watch for holes, ruts, rocks, hidden objects, or bumps which can cause you  
to slip or trip. Tall grass can hide obstacles.  
Extinguish all cigarettes, cigars, pipes and other sources  
of ignition.  
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.  
Never fuel machine indoors because flammable vapors will accumulate in  
the area.  
Never remove gas cap or add fuel while engine is hot or running. Allow  
engine to cool at least two minutes before refueling.  
Do Not:  
Never over-fill fuel tank. To allow for expansion of the fuel, do not fill above  
the bottom of the fuel tank neck.  
Do not mow near drop-offs, ditches or embankments, because you could  
lose your footing or balance.  
Replace gasoline cap and tighten securely.  
Do not mow slopes greater than 15 degrees as shown on the slope guide.  
Do not mow on wet grass. Unstable footing could cause slipping.  
If gasoline is spilled, wipe it off the engine and equipment. Move machine to  
another area. Wait 5 minutes before starting engine.

contains carbon monoxide, an odorless and deadly gas.  
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.  
NOTICE REGARDING EMISSIONS  
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 the Parts pages of this manual. Use of parts which do not meet  
the original equipment specifications may lead to improper performance  
and compromise safety!  
Engines which are certified to comply with California and federal EPA  
emission regulations for SORE (Small Off Road Equipment) are certified  
to operate on regular unleaded gasoline, and may include the following  
emission control systems: Engine Modification (EM), Oxidizing Catalyst (OC),  
Secondary Air Injection (SAI) and Three Way Catalyst (TWC) if so equipped.  
SPARK ARRESTOR  
Mower blades are sharp and can cut. Wrap the blade or wear gloves, and use  
extra caution when servicing them.  
WARNING  
Keep all nuts, bolts, and screws tight to be sure the equipment is in safe  
working condition.  
This machine is equipped with an internal combustion engine and should  
not be used on or near any unimproved forest-covered, brushcovered or  
grass-covered land unless the engine’s exhaust system is equipped with a  
spark arrestor meeting applicable local or state laws (if any).  
Never tamper with safety devices. Check their proper operation regularly.  
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.  
If a spark arrestor is used, it should be maintained in effective working order  
by the operator. In the State of California the above is required by law (Section  
4442 of the California Public Resources Code). Other states may have similar  
laws. Federal laws apply on federal lands.  
A spark arrestor for the muffler is available through your nearest Sears Parts  
and Repair Service Center. For location and purchase information call  
1-888-331-4569.  
Never attempt to make a wheel or cutting height adjustment while the  
engine is running.  
Grass Bagger 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 the Parts pages of this manual. Use of parts which do not meet the  
original equipment specifications may lead to improper performance and  
compromise safety!  
Do not change the engine’s governor setting or over-speed the engine. The  
governor controls the maximum safe operating speed of the engine.  
Check fuel line, tank, cap, and fittings frequently for cracks or leaks. Replace  
if necessary.  
Do not crank engine with spark plug removed.  
Maintain or replace safety and instruction labels, as necessary.

for a minimum of two minutes, allowing the underside of the cutting deck to  
thoroughly dry  
Clean underside of the mower deck once a season to prevent build-up of grass  
clippings or other debris. Follow steps below for this job.  
1.  
2.  
Allow the engine to run until it is out of fuel. Do not attempt to pour fuel  
from the engine. Disconnect spark plug wire. Refer to Engine Operator’s  
Manual.  
Tip mower so that it rests on the housing, keeping the muffler side down.  
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. Do not spray  
with water.  
IMPORTANT: Do not use a pressure washer or garden hose to clean your unit.  
These may cause damage to bearings, or the engine. The use of water will  
result in shortened life and reduce serviceability.  
4.  
Put the mower back on its wheels on the ground.  
Deck Wash (If Equipped)  
Your mower’s deck is equipped with a water port on its surface as part of its deck  
wash system.

OFF-SEASON STORAGE  
WARNING  
Never store lawn mower with fuel in tank indoors or in poorly ventilated  
areas where fuel fumes may reach an open flame, spark, or pilot light as on  
a furnace, water heater, clothes dryer, or gas appliance.  
Preparing The Engine  
Preparing The Lawn Mower  
For engines stored over 30 days:  
Clean and lubricate mower thoroughly as described in the lubrication  
instructions.  
To prevent gum from forming in fuel system or on carburetor parts, run  
engine until it stops from lack of fuel or add a gasoline additive to the gas  
in the tank. If you use a gas additive, run the engine for several minutes to  
circulate the additive through the carburetor.  
Do not use a pressure washer or garden hose to clean your unit.  
Coat mower’s cutting blade with chassis grease to prevent rusting.  
An oil change is not required but if you desire to change the oil then change  
while the engine is warm.  
WARNING  
When handling the cutting blade, protect your hands with a pair of heavy  
gloves or use a heavy rag to hold the blade.  
Clean engine of surface debris.  
Refer to Preparing the Engine for correct engine storage instructions.  
Store mower in a dry, clean area. Do not store next to corrosive materials,  
such as fertilizer.  
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.  
Battery  
The battery must be stored with a full charge. Extended storage of a  
discharged battery will reduce life and capacity of the battery. For optimal  
battery life, charge the battery once per month while in storage.  
Remove electric start push key and keep in a safe place out of the reach of  
children.
