SAFETY INSTRUCTIONS
• 
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. 
• 
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. 
• 
Allow machine to cool at least 5 minutes before storing.
General Service:
• 
Never run an engine indoors or in a poorly ventilated area. Engine exhaust 
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. 
• 
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!
• 
Mower blades are sharp and can cut. Wrap the blade or wear gloves, and use 
extra caution when servicing them.
• 
Keep all nuts, bolts, and screws tight to be sure the equipment is in safe 
working condition.
• 
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.
• 
Never attempt to make a wheel or cutting height adjustment while the 
engine is running.
• 
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 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.
• 
Observe proper disposal laws and regulations. Improper disposal of fluids 
and materials can harm the environment.
• 
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 a Sears or other qualified 
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.
NOTICE REGARDING EMISSIONS
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
 WARNING
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).
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.
