Power Rating
The gross power rating for individual gas engine models is labeled
in accordance with SAE (Society of Automotive Engineers) code
J1940 (Small Engine Power & Torque Rating Procedure), and rat-
ing performance has been obtained and corrected in accordance
with SAE J1995 (Revision 2002-05). Torque values are derived
at 3060 RPM; horsepower values are derived at 3600 RPM. Net
power values are taken with exhaust and air cleaner installed
whereas gross power values are collected without these attach-
ments. Actual gross engine power will be higher than net engine
power and is affected by, among other things, ambient operating
conditions and engine-to-engine variability. Given the wide array of
products on which engines are placed, the gas engine may not de-
velop the rated gross power when used in a given piece of power
equipment. This difference is due to a variety of factors including,
but not limited to, the variety of engine components (air cleaner,
exhaust, charging, cooling, carburetor, fuel pump, etc.), application
limitations, ambient operating conditions (temperature, humidity,
altitude), and engine-to-engine variability. Due to manufactur-
ing and capacity limitations, Briggs & Stratton may substitute an
engine of higher rated power for this Series engine.

Description
The walk-behind lawn mower is an engine powered rotary type
mower. The engine drives a cutting blade located under the mower
housing. The blade lifts and cuts through the grass. The height
of cut can be adjusted to give the lawn the desired finish. The cut
pieces of grass are either collected into a rear mounted grass bag
or, on some mowers, it can be recycled to feed the lawn. Recycling
the cut grass is known as “mulching”. Push models require the
operator to push the mower. Self-propelled models have a rear
wheel drive system to make mowing easier.
Intended Use/Limits Of Use
The walk-behind lawn mower is designed to cut lawn grass. Any
other use is not permitted. It is not designed to cut grass over
15cm in length or grass mixed with tall weeds. The lawn mower is
only suitable for private use in a domestic garden. It is not suitable
for cutting grass in public parks or playing fields.

How To Prepare The Engine - Figure 13 14
NOTICE: The engine does not contain oil. Before you start the
engine, make sure you add oil according to the instructions in
this manual. If you start the engine without oil, it will be damaged
beyond repair and will not be covered under warranty.
Oil Recommendations
We recommend the use of Briggs & Stratton Warranty Certified
oils for best performance. Other high-quality detergent oils are
acceptable if classified for service SF, SG, SH, SJ or higher. Do not
use special additives.
Outdoor temperatures determine the proper oil viscosity for the
engine. Use the chart to select the best viscosity for the outdoor
temperature range expected.
* Below 40°F (4°C) the use of SAE 30 will result in hard starting.
** Above 80°F (27°C) the use of 10W-30 may cause increased oil
consumption. Check oil level more frequently.
How To Check/Add Oil
Before adding or checking the oil
• Place engine level.
• Clean the oil fill area of any debris.
1. Remove the dipstick (A) and wipe with a clean cloth
(Figure 13).
2. Insert and tighten the dipstick.
3. Remove the dipstick and check the oil level. It should be at the
top of the full indicator (B) on the dipstick.
4. If low, add oil slowly into the engine oil fill (C). Do not overfill.
After adding oil, wait one minute and then recheck the oil
level.
5. Replace and tighten the dipstick.
Fuel Recommendations
Fuel must meet these requirements:
• Clean, fresh, unleaded gasoline.
• A minimum of 87 octane/87 AKI (91 RON). High altitude use,
see below.
• Gasoline with up to 10% ethanol (gasohol) or up to 15%
MTBE (methyl tertiary butyl ether) is acceptable.
CAUTION: Do not use unapproved gasolines, such as E85. Do not
mix oil in gasoline or modify the engine to run on alternate fuels.
This will damage the engine components and void the engine war-
ranty.
To protect the fuel system from gum formation, mix a fuel stabi-
lizer into the fuel. See Storage. All fuel is not the same. If starting
or performance problems occur, change fuel providers or change
brands. This engine is certified to operate on gasoline. The emis-
sions control system for this engine is EM (Engine Modifications).
High Altitude
At altitudes over 5,000 feet (1524 meters), a minimum 85 oc-
tane/85 AKI (89 RON) gasoline is acceptable. To remain emissions
compliant, high altitude adjustment is required. Operation without
this adjustment will cause decreased performance, increased fuel
consumption, and increased emissions. See a Briggs & Stratton
Authorized Dealer for high altitude adjustment information.
Operation of the engine at altitudes below 2,500 feet (762 meters)
with the high altitude kit is not recommended.

How To Use As A Mulcher - Figure 1 10
WARNING: Before you install or remove the mulcher
plug, disconnect the spark plug wire and keep it away
from the spark plug.
1. For mulching grass, remove the grass bag (I) and the side dis-
charge chute (M) from the mower. See Figure 1.
2. Raise the rear door (B) and install the mulcher plug (A) into
the rear discharge opening. See Figure 10.
Mowing Tips
Some models have an optional mulcher plug. If the mulcher plug
is installed, the grass is finely cut and will easily recycle. Because
the nutrients are returned to the soil, the lawn will need less fertil-
izer.
The following tips will increase performance and improve the ap-
pearance of the lawn.
• The grass must be dry. If the grass is wet, it will be difficult to
cut and cause heavy clumps of grass.
• The grass must not be too tall. The maximum height to effec-
tively cut is 9.8 cm. Set the height adjusters so that only the
top third of the grass is cut.
• If the grass is more than 9.8 cm high, two mowings will be
necessary. For the first mowing, set the height adjusters in
the highest position. Then, lower the height adjusters for the
second mowing.
• Keep a sharp edge on the blade. A blade that is not sharp will
cause the ends of the grass to become brown.
• Clean the bottom of the mower housing. If grass and other
debris accumulate on the bottom of the mower housing,
performance will be reduced.
To improve the quality of cut, try the following:
• raise height of cut
• cut more frequently
• operate at a slower ground speed
• reduce width of cut
• change direction
• mow a second time

Storage
WARNING: Fuel and its vapors are extremely flammable
and explosive.
Fire or explosion can cause severe burns or death.
When Storing Fuel Or Equipment With Fuel In Tank
• Store away from furnaces, stoves, water heaters or other
appliances that have pilot lights or other ignition sources
because they can ignite fuel vapors.
Fuel System
Fuel can become stale when stored over 30 days. Stale fuel causes
acid and gum deposits to form in the fuel system or on essential
carburetor parts. To keep fuel fresh, use Briggs & Stratton FRESH
START®fuel stabilizer, available as a liquid additive or a drip con-
centrate cartridge.
There is no need to drain gasoline from the engine if a fuel
stabilizer is added according to instructions. Run the engine for 2
minutes to circulate the stabilizer throughout the fuel system. The
engine and fuel can then be stored up to 24 months.
If gasoline in the engine has not been treated with a fuel stabilizer,
it must be drained into an approved container. Run the engine until
it stops from lack of fuel. The use of a fuel stabilizer in the storage
container is recommended to maintain freshness.
Engine Oil
While the engine is still warm, change the engine oil.
Folding Handle Storage
NOTICE: Be careful when you fold or raise the handle. Do not dam-
age the cables. A cable that is bent will not work correctly. Before
you use the unit, replace a bent or damaged cable.
How To Fold The Handle - Figure 21 22
1. Loosen the knobs (A) that hold the upper handle (B) to the
lower handle (C). See Figure 21.
NOTICE: As you fold or raise the handle, make sure that the
cables are not caught between the upper and lower handles or
around the handle fasteners.
2. Rotate the upper handle (B) toward the back of the unit. See
Figure 22.
3. Remove knobs (C) and the fasteners that secure the lower
handle to the handle bracket (D).
4. Rotate the handle forward over the engine as shown. Make
sure that the cables are not damaged.
How To Raise The Handle - Figure 2 3 4
1. Raise the lower handle (A) to the operating position
(Figure 2).

Use hole (C) to mount the handle in the high position. Use
hole (D) to mount the handle in the low position.
3. Mount the handle in either hole (C) or hole (D) with the fasten-
ers as shown. Tighten knobs (E) until the lower handle is
secure.
4. Put the upper handle (G) in the operating position (Figure 4).
Tighten the knobs (F) until the upper handle and lower handle
are locked in place.
How To Prepare The Mower For Storage
1. Clean the dirt and debris from the cylinder cooling fins and the
engine housing.
2. Clean the bottom of the mower housing.
3. Completely clean the mower to protect the paint.
4. Put the unit in a building that has good ventilation.
5. Make sure the grass bag is empty of grass. Grass remaining
in the bag during storage will damage the bag.
NOTICE: Store the engine level (normal operating position). If the
engine is tipped for storage, the fuel tank must be empty and the
spark plug side must be up. If the fuel tank is not empty and if the
engine is tipped in any other direction, it may be difficult to start

LOOK FOR RELEVANT EMISSIONS DURABILITY PERIOD AND AIR INDEX INFORMATION ON YOUR ENGINE
EMISSIONS LABEL
The California Air Resources Board, U.S. EPA, and Briggs & Stratton (B&S)
are pleased to explain the emissions control system warranty on your Model
Year 2011-2012 engine/equipment. In California, new small off-road
engines must be designed, built, and equipped to meet the State’s stringent
anti-smog standards. B&S must warrant the emissions control system on your
engine/equipment for the periods of time listed below provided there has been
no abuse, neglect, or improper maintenance of your small off-road engine.
Your emissions control system may include parts such as the carburetor or
fuel injection system, fuel tank, ignition system, and catalytic converter. Also
included may be hoses, belts, connectors, sensors, and other emissions-related
assemblies. Where a warrantable condition exists, B&S will repair your engine/
equipment at no cost to you including diagnosis, parts, and labor.
Manufacturer’s Warranty Coverage:
Small off-road engines are warranted for two years. If any emissions-related part
on your engine/equipment is defective, the part will be repaired or replaced by
B&S.
Owner’s Warranty Responsibilities:
s!STHESMALLENGINEEQUIPMENTowner, you are responsible for the performance
of the required maintenance listed in your owner’s manual. B&S recommends that
you retain all receipts covering maintenance on your engine/equipment, but B&S
cannot deny warranty solely for the lack of receipts or your failure to ensure the
performance of all scheduled maintenance.
s!STHEENGINEEQUIPMENTowner, you should however be aware that B&S may
deny you warranty coverage if your engine/equipment or a part has failed due to
abuse, neglect, improper maintenance, or unapproved modifications.
sYou are responsible for presenting your engine/equipment to a B&S distribution
center, servicing dealer, or other equivalent entity, as applicable, as soon as a
problem exists. The warranty 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 B&S at [phone].
Engines that are certified to meet the California Air Resources Board (CARB)
Emissions Standard must display information regarding the Emissions Durability
Period and the Air Index. Briggs & Stratton makes this information available to
the consumer on our emissions labels. The engine emissions label will indicate
certification information.
The Emissions Durability Period describes the number of hours of actual
running time for which the engine is certified to be emissions compliant, assuming
proper maintenance in accordance with the Operating & Maintenance Instructions.
The following categories are used:
Moderate:
Engine is certified to be emissions compliant
for 125 hours of actual engine running time.
Intermediate:
Engine is certified to be emissions compliant
for 250 hours of actual engine running time.
Extended:
Engine is certified to be emissions compliant
for 500 hours of actual engine running time.
For example, a typical walk-behind lawn mower is used 20 to 25 hours per year.
Therefore, the Emissions Durability Period of an engine with an intermediate
rating would equate to 10 to 12 years.
Briggs & Stratton engines are certified to meet the United States Environmental
Protection Agency (USEPA) Phase 2 emissions standards. For Phase 2 certified
engines, the Emissions Compliance Period referred to on the Emissions
Compliance label indicates the number of operating hours for which the engine
has been shown to meet Federal emissions requirements.
For engines less than 225 cc displacement:
Category C = 125 hours
Category B = 250 hours
Category A = 500 hours
For engines of 225 cc or more displacement:
Category C = 250 hours
Category B = 500 hours
Category A = 1000 hours
