Carefully read and follow all of
the safety instructions below.
The American Academy of Pediatrics recommends that children be a minimum of
12 year of age before operating a pedestrian controlled lawn mower and a minimum of 16 years of age before operating a
riding lawn mower.
Tragic accidents can occur if the op er a tor is
not alert to the presence of children. Children
are often attracted to the ma chine and the
mowing activity. Never assume that children
will remain where you last saw them.
• Keep children out of the mowing area
and under the watchful care of a re spon-
si ble adult other than the operator.
• Be alert and turn machine off if chil dren
enter the area.
• Before and while walking back wards,
look behind and down for small chil dren.
• Never allow children to operate the
machine.
II. GENERAL OPERATION
• Read, understand, and follow all
in struc tions on the machine and in the
manual(s) before starting. Be thor ough ly
familiar with the controls and the proper
use of the machine before starting.
• Do not put hands or feet near or under
rotating parts. Keep clear of the dis charge opening at all times.
• Only allow responsible individuals, who
are familiar with the in struc tions, to operate the machine.
• Clear the area of objects such as rocks,
toys, wire, bones, sticks, etc., which
could be picked up and thrown by blade.
Stay behind the handle when the engine
(motor) is running.
• Be sure the area is clear of other people
before mowing. Stop ma chine if anyone
enters the area.
• Do not operate machine bare footed or
while wearing sandals. Al ways wear
substantial footwear with good ankle
support while mowing.
• Do not pull mower backwards unless
absolutely nec es sary. Always look down
and behind before and while moving
backwards.
• Never direct discharged material toward
anyone. Avoid discharging material against
a wall or obstruction. Material may richochet back toward the operator. Stop blade
when crossing gravel surfaces.
• Do not operate the mower without
proper guards, plates, grass catcher or
oth er safety protective devices in place.
• See manufacturer’s instructions for proper operation and installation of accessories. Only use accessories approved by
the manufacturer.
• Stop the blade(s) when crossing grav el
drives, walks, or roads.
• Never leave a running machine unattended.
• Stop the engine (motor) and wait until the
blade comes to a complete stop before
clean ing the machine, removing the grass
catcher, or unclogging the discharge chute.

• Do not operate the machine while under
the infl uence of alcohol or drugs.
• Never operate machine in wet grass.
Always be sure of your footing: keep a
fi rm hold on the handle; walk, never run.
• Disengage the drive system, if so equipped,
before starting the engine (motor).
• If the equipment should start to vi brate
abnormally, stop the engine (motor) and
check immediately for the cause. Vibration is generally a warning of trouble.
• Always wear eye protection when op er at ing machine.
• Use extra care when approaching blind
corners, shrubs, trees, or other objects
that may obscure vision.
• When loading or unloading this machine,
do not exceed the maximum recommended operation angle of 15°.
• Wear proper Personal Protective Equipment (PPE) while operating this machine, including (at a minimum) sturdy
footwear, eye protection, and hearing
protection. Do not mow in shorts or
open toed footwear.
Always let someone know you are outside
mowing.
III. SLOPE OPERATION
Slopes are a major factor related to slip &
fall accidents, which can result in severe
injury. All slopes require extra caution. If
you feel uneasy on a slope, do not mow it.
DO:
• Mow across the face of slopes: nev er
up and down. Exercise extreme caution
when changing direction on slopes.
• Remove obstacles such as rocks, tree
limbs, etc.
• Watch for holes, ruts, bumps or hidden
objects. Uneven terrain could cause a
slip and fall accident. Tall grass can hide
obstacles.
DO NOT:
• Do not mow near drop-offs, ditches or
embankments. You could lose your footing or balance.
• Do not mow on wet grass or excessively
steep slopes. Poor footing could cause a
slip and fall accident.
IV. SAFE HANDLING OF GASOLINE
To avoid personal injury or property damage, use extreme care in handling gasoline. Gasoline is extremely fl ammable and
the vapors are explosive.
• Extinguish all cigarettes, cigars, pipes
and other sources of ignition.
• Use only an approved container.
• Never remove gas cap or add fuel with
the engine running.
• Allow engine to cool before refueling.
• Never refuel the machine indoors.
• Never store the machine or fuel container where there is an open fl ame, spark
or pilot light such as a water heater or on
other appliances.
• Never fi ll containers inside a vehicle, on
a truck or trailer bed with a plastic liner.
Always place containers on the ground
away from your vehicle before fi lling.
• Remove gas-powered equipment from
the truck or trailer and refuel it on the
ground. If this is not possible, then
refuel such equipment 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.
• If fuel is spilled on clothing, change
clothing immediately.
• Never overfi ll fuel tank. Replace gas
cap and tighten securely.
V. GENERAL SERVICE
• Never run a machine inside a closed area.
• Never make adjustments or repairs with
the engine (motor) running. Dis con nect the
spark plug wire, and keep the wire away
from the plug to prevent ac ci den tal starting.
• Keep all nuts and bolts tight to be sure the
equipment is in safe working condition.
• Never tamper with safety devices.
Check their proper operation reg u lar ly.
Never do anything to interfere with the
intended function of a safety device
or reduce the protection provided by a
safety device.
• Keep machine free of grass, leaves, or
other debris build-up. Clean oil or fuel spillage. Allow machine to cool before storing.
• Stop and inspect the equipment if you
strike an object. Repair, if nec es sary,
before restarting.
• Never attempt to make wheel height
adjustments while the engine is running.
• Grass catcher components are sub ject
to wear, dam age, and de te ri o ra tion,
which could expose moving parts or
allow objects to be thrown. Frequently
check com po nents and replace with
man u fac tur er’s recommended parts,
when necessary.
• Mower blades are sharp and can cut.
Wrap the blade(s) or wear gloves, and
use extra caution when ser vic ing them.
• Do not change the engine governor setting or overspeed the engine.
• Maintain or replace safety and instruction labels, as necessary.

DISCLAIMERS: THE WARRANTIES AND REMEDIES CONTAINED HEREIN ARE
EXCLUSIVE AND IN LIEU OF ALL OTHER WARRANTIES, WHETHER ORAL OR
WRITTEN (OTHER THAN AS STATED HEREIN), AND WHETHER EXPRESS, IMPLIED
OR STATUTORY, INCLUDING BUT NOT LIMITED TO ANY. THIS WARRANTY

PROVINCE.
IN NO EVENT SHALL SEARS BE LIABLE FOR ANY INCIDENTAL, SPECIAL, INDIRECT
OR CONSEQUENTIAL DAMAGES, WHETHER RESULTING FROM THE USE, MISUSE
OR INABILITY TO USE THE PRODUCT OR FROM DEFECTS IN THE PRODUCT. THE
EXCLUSIONS IN THIS PARAGRAPH SHALL NOT APPLY IN JURISDICATIONS WHERE

additional instructions or information provided at the time of purchase or in subsequent
communications to the purchaser from time to time, exhibit reasonable care in the use,
operation, maintenance, general upkeep and storage of the product. Failure to comply

Engine Power Rating Information
The gross power rating for individual gas engine models is labeled in accordance with SAE (Society of Automo-tive Engineers) code J11940 (Small Engine Power & Torque Rating Procedure),
and rating performance has been obtained and corrected in accordance with SAE J1995 (Revision
2002-5). Actual gross engine power will be lower and is affected by, among other things, ambient operating conditions and engine-to-engine variability. Given both the wide array of products
on which engines are placed and the variety of environmental issues applicable to operating the
equipment, the gas engine will not develop the rated gross power when used in a given piece of
power equipment (actual “on-site” or net horsepower). This difference is due to a variety of factors
including, but not limited to, accessories (air cleaner, exhaust, charging, cooling, carburetor, fuel
pump, etc.), application limitations, ambient operating conditions (temperature, humidity, altitude),
and engine-to-engine variability. Due to manufacturing and capacity limitations, Briggs & Stratton
may substitute an engine of higher rated power for this Series engine.
