Operation
Before Starting The Engine
This engine was shipped from the factory without
oil. If you start the engine without oil, the engine
will be damaged beyond repair and will not be
covered under warranty.
CAUTION
Eye Protection
Always wear safety glasses. If you wear eye glasses,
put a Wide Vision Safety Mask over your eye glasses.
Oil Capacity
The engine holds approximately 0.5 liter (18 ounces)
of oil.
Oil Recommendation
•Do not use special additives.
•Choose a viscosity from the following chart.
SAE 30 5ºC and higher (40ºF and higher)
is good for all purpose use above 40ºF, use below
40ºF will cause hard starting.
10W-30 --18 to 38ºC(0to100ºF)
is better for varying temperature conditions. This
grade of oil improves cold weather starting, but may
increase oil consumption at 80ºF(27ºC) or higher.
Check oil level frequently at higher temperatures.
Synthetic 5W-30 --30 to 40ºC (--20 to 120ºF)
provides the best protection at all temperatures as
well as improved starting with less oil consumption.
5W-30 5ºC and below (40ºF and below)
is recommended for winter use, and works best in
cold conditions.
Check/Add Oil
Before adding or checking the oil
•Place engine level.
•Clean the oil fill area of any debris.
Dipstick (Figure 6)
1. Remove the dipstick (B) and wipe with a clean cloth.
2. Insert and tighten the dipstick.
3. Remove the dipstick and check the oil level. Make
sure the oil is at the FULL mark (C) on the dipstick.
4. To add oil, pour the oil slowly into the engine oil fill
(B). DO NOT OVERFILL. After adding oil, wait one
minute and then recheck the oil level.
5. Fill to the FULL mark (C) on the dipstick.

Fuel Recommendations
This engine is certified to operate on gasoline. The
emissions control system for this engine is EM
(Engine Modifications).
Gasoline must meet these requirements:
•Clean, fresh, unleaded gasoline.
•A minimum of 87 octane/87 AKI (91 RON). If
operating at high altitude, see below.
•Gasoline with up to 10% ethanol (gasohol) or up
to 15% MTBE (methyl tertiary butyl ether), is
acceptable.
•Use of any gasoline not consistent with the
requirements will void the engine warranty.
In some local areas, fuel pumps may be marked if the
gasoline contains alcohols or ethers. If you are unsure
about the gasoline you purchase, check with your fuel
provider.
•Do not modify the engine fuel system or
carburetor to run on alternative fuels.
•Never mix oil with gasoline.
All gasoline is not the same. If you experience starting
or performance problems after new gasoline has been
used in your engine, switch to a different fuel provider
or change fuel brands.
Some fuels, called oxygenated or reformulated fuels,
are fuels blended with alcohols or ethers. Excessive
amounts of these blends can damage the fuel
system or cause performance problems. If any
undesirable operating symptoms occur, use gasoline
with a lower percentage of alcohol or ether.
CAUTION
Fuel Stabilizer
To protect the fuel system from gum formation, mix in
a fuel preservative when adding fuel. Briggs &
Stratton recommends using FRESH STARTtfuel
stabilizer, available as a liquid additive or a
concentrated liquid cartridge.
High Altitude use
At higher altitudes (over 5,000 feet), 85 octane/85
AKI (89 RON) gasoline can be used. Operation at
high altitude may require a high-altitude carburetor jet
kit to improve performance and decrease fuel
consumption.
Add Fuel (Figure 7)
Gasoline and its vapors are
extremely flammable and explosive.
Fire or explosion can cause severe
burns or death.
•Turn engine off and let engine cool at least 2
minutes before removing the gas cap.
•Fill fuel tank outdoors or in well-ventilated area.
•Keep gasoline away from sparks, open flames,
pilot lights, heat, and other ignition sources.
•If fuel spills, wait until it evaporates before
starting engine.

entanglement, traumatic
amputation, or laceration.
The cutting blade is sharp and can
result in traumatic amputation or
laceration to the hands.
WARNING
Frequently check the blade for wear or damage such
as cracks. Frequently check the bolt that holds the
blade. Keep the bolt tight. If the blade hits an object,
stop the engine. Disconnect the wire to the spark
plug. Check the blade adapter for damage. Check for
a bent or damaged blade, a badly worn blade, or
other damage. Before you operate the unit, damaged
parts must be replaced with factory replacement
parts. For safety, replace the blade every two years.
Keep a sharp edge on the blade. A blade that is not
sharp will cause the ends of the grass to become
brown. Remove the blade as follows.
How To Remove The Blade (Figure 16)
1. Drain the fuel tank.
2. Lift the side of the mower that has the muffler or
spark plug.
3. Use a piece of wood to keep the blade from
rotating.
4. Remove the bolt (A) that holds the blade (B).
5. Check the blade and blade adapter (C) according
to the “Blade Service” instructions. If badly worn or
damaged, replace with factory replacement parts.
6. Mount the blade with the curved edges toward the
housing. If the blade is upside down, the blade will
not cut correctly and can cause an accident.
7. Fasten the blade with the original washer(s) (D)
and bolt. Make sure the outside rim of the
Belleville washer (D) is toward the blade.
8. Tighten the bolt that holds the blade to a torque of

How To Sharpen The Blade (Figure 17)
1. Sharpen the blade (B) two times a year or every
25 hours.
2. If the blade is on the unit, do not sharpen. Remove
the blade according to the instructions in “How To
Remove The Blade”.
3. Clean the blade with a brush, soap, and water.
Check the blade. Look for cracks, nicks, or other
damage. Replace a blade that is badly worn, bent,
or damaged with a factory replacement blade.
4. Sharpen the blade with a file (C). Make sure you
keep the original beveled cutting edge (Figure 17).
5. Make sure the blade is balanced. Use a
screwdriver (D) and hold the blade parallel to the
ground as shown. A blade that is balanced will
stay parallel to the ground. If the blade is not
balanced, the heavy end will rotate toward the
ground. Sharpen the heavy end until the blade is
balanced.
6. A new blade will cut better than a badly worn
blade. Every two years replace the old blade with
a factory replacement blade.
Check The Level Of Cut
Test the unit in a small area. If the height of cut is not

Storage (over 30 days)
Mower
1. Disconnect the spark plug wire and keep it away
from the spark plug.
2. Clean the bottom of the mower housing.
3. Make sure the grass bag is empty of grass. Grass
remaining in the bag during storage will damage
the bag.
4. Completely clean the mower to protect the paint.
5. Put the unit in a building that has good ventilation.
Engine
Gasoline and its vapors are
extremely flammable and explosive.
Fire or explosion can cause severe
burns or death.
When Storing Gasoline 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 gasoline vapors.
WARNING
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. Mix
fuel stabilizer with the fuel in the tank or storage
container. Run the engine for a short time to circulate
stabilizer through the carburetor and engine. Engine
and fuel can then be stored up to 24 months.
If fuel stabilizer is used, you do not need to drain the
gasoline prior to storage. If fuel stabilizer is not used,
run the engine until it stops from lack of fuel.
If a FRESH STARTtfuel cap with a cartridge of
concentrated slow drip stabilizer is used, there is no
need to drain the fuel for seasonal storage as long as
the cartridge contains stabilizer.
Engine oil
While the engine is still warm, change the engine oil.
Lubricate cylinder and piston
Remove the spark plug and pour approximately 1 oz
(30 ml) of engine oil into the spark plug hole. Replace
the spark plug and slowly pull the starter rope to
distribute the oil.
Clean engine
Clean engine of surface debris, chaff, or grass.
Storage Area
Store in a clean, dry area. Do not store in the same
area as a stove, furnace, water heater, or other
appliance that uses a pilot light or has a device that
can create a spark.
