Attaching the Mulching Plate
WARNING: To prevent the engine from
starting, disconnect the wire from the
spark plug.
1. Raise the chute deflector (A, Figure 5).
2. Align the mulcher plate (B) with the side discharge
opening. Make sure that the two alignment bumps (C)
are inside the opening.
3. Mount the tab (D) on the top of the mulcher plate to the
inside of the mower housing.
4. Mount the tab (E) on the bottom of the mulcher plate to
the inside of the mower housing.
5. Lower the chute deflector.
6. Attach the wire to the spark plug.
Note: On some models, the mulcher kit is installed at the
factory. To convert from a mulcher to a side discharge,
simply remove the mulching plate.
Mulching Tips
Mulching finely cuts the grass so that the grass can be easily
recycled. Because the nutrients are returned to the soil, the
lawn will need less fertilizer. To correctly mulch the lawn,
follow the tips below.
• 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
effectively cut is 4 1/2 inches. Set the height adjusters
so that only the top third of the grass is cut.
• If the grass is more than 4 1/2 inches 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 underside of the mower housing. Grass and
other debris can keep the mower from working
correctly.
If the quality of cut is marginal, try the following:
• Set the height adjusters at a higher cutting height.
• Cut the grass more frequently.
• Operate the mower at a slower ground speed.
• Overlap the cutting swaths instead of cutting a full
swath with each pass.
• Mow across the marginal areas a second time.

Preparing the Engine
ENGINE DOES NOT CONTAIN OIL OR GASOLINE
Using the bottle of oil supplied in the carton, fill the engine
with the proper amount of oil. See the engine manufacturer’s
instructions for the type of gasoline and oil to use. Before
you use the unit, read the information on safety, operation,
maintenance, and storage.
WARNING: Follow the engine manufacturer’s
instructions for the type of gasoline and oil to
use. Always use a safety gasoline container.
Do not smoke when adding gasoline to the
engine. When inside an enclosure, do not
fill with gasoline. Before you add gasoline,
stop the engine. Let the engine cool for
several minutes.
Note: The operation of a new engine will sometimes result in
a slight amount of smoke. This smoke is caused by paint or
oil on or around the muffler. This is normal and only
expected during initial operation.
IMPORTANT: This unit is equipped with an internal
combustion engine and must not be used on or near any
unimproved forest-covered, brush-covered or grass-covered
and unless the engine’s exhaust system is equipped with a
spark arrester meeting applicable local or state laws (if any).
If a spark arrester is used, it must 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. See an Authorized Service Center for a spark
arrester for the muffler.
Note: Actual sustained engine power will likely be lower due
to operating limitations and environmental factors.
Final Preparation
Before you use the mower, check the assembly of the
wheels, the handle, and the controls. Make sure all the
fasteners are tight. Make sure the throttle control (if
equipped) and the engine stop lever work correctly.
If the mower is equipped with height adjusters, make sure
the height adjusters function properly. Before starting the
engine, make sure each height adjuster is set at the desired
height. See “Adjusting The Height Of Cut”

5. Check the blade (C) according to the “Blade Service”
instructions. Replace a badly worn or damaged blade
with a factory replacement blade.
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 (D) and bolt.
Make sure the outside rim of the Belleville washer is
toward the blade.
8. Tighten the bolt that holds the blade to a torque of 30
foot pounds.
WARNING: Always keep the bolt that holds the
blade tight. A loose bolt or blade can cause an
accident.
Sharpening the Blade
WARNING: Vibration is the result if the blade
is not correctly balanced. A blade that is
damaged with cracks can break and cause
an accident.
1. Sharpen the blade 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 “Removing 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 (A, Figure 12, next page) with a file
(B). Make sure you keep the original beveled cutting
edge.
5. Make sure the blade is balanced. Use a screwdriver (C)
and hold the blade parallel to the ground (D) 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.
Checking the Level of Cut
Test the unit in a small area. If the height of cut is not level
or if the cut grass is not discharged, the cause can be: (1)
the blade is bent or damaged, (2) the blade is not sharp, (3)
a worn blade, (4) or a broken blade adapter. Before you use
the unit, correct the problem.

Maintenance
Preparing the Mower for Storage
WARNING: Do not remove gasoline while
inside a building, near a fire, or while you
smoke. Gasoline fumes can cause an
explosion or a fire.
1. Drain the fuel tank.
2. Let the engine run until it is out of gasoline.
3. Drain the oil from the warm engine. Fill the engine
crankcase with new oil.
4. Remove the spark plug from the cylinder. Pour one
ounce of oil into the cylinder. Slowly pull the recoil-start
grip so that the oil will protect the cylinder. Install a new
spark plug in the cylinder.
5. Clean the dirt and debris from the cylinder cooling fins
and the engine housing.
6. Clean the bottom of the mower housing.
7. Make sure the grass bag is empty of grass. Grass
remaining in the bag during storage will damage the
bag.
8. Completely clean the mower to protect the paint.
9. Fold the handles (if desired).
CAUTION: Be careful when you fold or raise the handle. Do
not damage the cables. A cable that is bent will not work
correctly. Before you use the unit, replace a bent or damaged
cable.
10. Put the unit in a building that has good ventilation.

ABOUT YOUR WARRANTY
We welcome warranty repair and apologize to you for being inconvenienced. Warranty service is available only through servicing
dealers authorized by Briggs & Stratton or BSPPG, LLC.
Most warranty repairs are handled routinely, but sometimes requests for warranty service may not be appropriate. This warranty
only covers defects in materials or workmanship. It does not cover damage caused by improper use or abuse, improper
maintenance or repair, normal wear and tear, or stale or unapproved fuel.
Improper Use and Abuse - The proper, intended use of this product is described in the Operator’s Manual. Using the product in
a way not described in the Operator’s Manual or using the product after it has been damaged will void your warranty. Warranty is
not allowed if the serial number on the product has been removed or the product has been altered or modified in any way, or if the
product has evidence of abuse such as impact damage, or water/chemical corrosion damage.
Improper Maintenance or Repair - This product must be maintained according to the procedures and schedules provided in the
Operator’s Manual, and serviced or repaired using genuine Briggs & Stratton parts. Damage caused by lack of maintenance or use
of non-original parts is not covered by warranty.

cover repairs when normal use has exhausted the life of a part or the equipment. Maintenance and wear items such as filters,
belts, cutting blades, and brake pads (engine brake pads are covered) are not covered by warranty due to wear characteristics
alone, unless the cause is due to defects in material or workmanship.
Stale Fuel - In order to function correctly, this product requires fresh fuel that conforms to the criteria specified in the Operator’s
Manual. Damage caused by stale fuel (carburetor leaks, clogged fuel tubes, sticking valves, etc) is not covered by warranty.

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 rating performance has been
obtained and corrected in accordance with SAE J1995 (Revision 2002-05). Torque values are derived at 3060 RPM; horsepow-
er values are derived at 3600 RPM. Net power values are taken with exhaust and air cleaner installed whereas gross power val-
ues are collected without these attachments. 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 develop the rated gross power when used in a given piece of power equip-
ment. 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 manufacturing and capacity limitations, Briggs & Stratton may sub-
stitute an engine of higher rated power for this Series engine.
