DO:
• Mow across the face of slopes: never
up and down. Exercise extreme caution
when changing direction on slopes.
• Remove obstacles such as rocks, tree
limbs, etc.
• Watch for holes, ruts, or bumps. Tall
grass can hide obstacles.
DO NOT:
• Do not trim near drop-offs, ditches or
embankments. The operator could lose
footing or balance.
• Do not trim excessively steep slopes.
• Do not mow on wet grass. Reduced
footing could cause slipping.
• Never fill 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 filling.
• 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 overfill fuel tank. Replace gas
cap and tighten securely.
III. CHILDREN
Tragic accidents can occur if the operator is
not alert to the presence of children. Children
are often attracted to the machine and the
mowing activity. Never assume that children
will remain where you last saw them.
• Keep children out of the trimming area
and under the watchful care of another
responsible adult.
• Be alert and turn machine off if children
enter the area.
• Before and while walking backwards,
look behind and down for small children.
• Never allow children to operate machine.
• Use extra care when approaching blind
corners, shrubs, trees, or other objects
that may obscure vision.
V. GENERAL SERVICE
• Never run machine inside a closed area.
• Never make adjustments or repairs with
the engine (motor) running. Disconnect the
spark plug wire, and keep the wire away
from the plug to prevent accidental starting.
• Keep nuts and bolts, especially blade
attachment bolts, tight and keep equipment in good condition.
• Never tamper with safety devices.
Check their proper operation regularly.
• 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 necessary,
before restarting.
• Never attempt to make wheel height
adjustments while the engine is running.
• Grass catcher components are subject to
wear, damage, and deterioration, which
could expose moving parts or allow objects
to be thrown. Frequently check components and replace with manufacturer’s
recommended parts, when necessary.
• Mower blades are sharp and can cut.
Wrap the blade(s) or wear gloves, and
use extra caution when servicing them.
• Do not change the engine governor setting or overspeed the engine.
• Maintain or replace safety and instruction labels, as necessary.
IV. SAFE HANDLING OF GASOLINE
Use extreme care in handling gasoline.
Gasoline is extremely flammable 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 flame, spark
or pilot light such as a water heater or
on other appliances.
WARNING: This lawn mower is equipped with an internal combustion engine and
should not be used on or near any unimproved forest-covered, brush-covered or
grass-covered land 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
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 arrester for the muffler is available through your nearest Husqvarna or
other authorized service center (See the REPAIR PARTS section of this manual).

ACCESSORIES
These accessories were available when this lawn mower was produced. They are not
shipped with your mower. They are also available at most Husqvarna retailers and
service centers. Some of these accessories may not apply to your lawn mower.
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.

SIMPLE STEPS TO REMEMBER WHEN
CONVERTING YOUR LAWN MOWER
CAUTION: Alcohol blended fuels
(called gasohol or using ethanol or methanol) can attract moisture which leads to
separation and formation of acids during
storage. Acidic gas can damage the fuel
system of an engine while in storage. To
avoid engine problems, the fuel system
should be emptied before storage of 30
days or longer. Empty the gas tank, start
the engine and let it run until the fuel lines
and carburetor are empty. Use fresh fuel
next season. See Storage Instructions for
additional information. Never use engine
or carburetor cleaner products in the fuel
tank or permanent damage may occur.
FOR MULCHING 1. Rear mulcher plug installed.
2. Mulcher door closed.
FOR REAR BAGGING 1. Rear mulcher plug removed.
2. Grass catcher installed.
3. Mulcher door closed.
FOR SIDE DISCHARGING 1. Rear mulcher plug installed.
2. Discharge deflector installed.
CAUTION: Do not run your lawn mower without mulcher plug, clipping deflector
or approved grass catcher in place. Never
attempt to operate the lawn mower with
the rear door removed or propped open.
Engine
oil cap
BEFORE STARTING ENGINE
ADD OIL
Your lawnmower is shipped without oil in
the engine. For type and grade of oil to
use, see “ENGINE” in the Maintenance
section of this manual.
CAUTION: DO NOT overfill engine with
oil, or it will smoke heavily from the muffler
on startup.
1. Be sure lawnmower is level.
2. Remove oil dipstick from oil fill spout.
3. You receive a container of oil with the
unit. Slowly pour the entire container
down the oil fill spout into the engine.
NOTE: Initial oil fill requires only 18 oz.
due to residual oil in engine from the
manufacturers 100% quality testing. When
changing oil you may need 20 oz.
4. Insert and tighten dipstick.
IMPORTANT:
• Check oil level before each use. Add oil
if needed. Fill to full line on dipstick.
• Change the oil after every 25 hours of
operation or each season. You may
need to change the oil more often
under dusty, dirty conditions. See “TO
CHANGE ENGINE OIL” in the Maintenance section of this manual.
ADD GASOLINE
• Fill fuel tank to bottom of tank filler neck.
Do not overfill. Use fresh, clean, regular
unleaded gasoline with a minimum of 87
octane. Do not mix oil with gasoline. Purchase fuel in quantities that can be used
within 30 days to assure fuel freshness.
CAUTION: Wipe off any spilled oil or
fuel. Do not store, spill or use gasoline
near an open flame.

TO STOP ENGINE
• To stop engine, release operator presence control bar.
TO START ENGINE
NOTE: Due to protective coatings on the
engine, a small amount of smoke may be
present during the initial use of the product
and should be considered normal.
1. To start a cold engine, push primer
three (3) times before trying to start.
Use a firm push. This step is not
usually necessary when starting an
engine which has already run for a few
minutes.
2. Hold operator presence control bar
down to the handle and pull starter
handle quickly. Do not allow starter
rope to snap back.
NOTE: In cooler weather it may be
necessary to repeat priming steps. In
warmer weather over priming may cause
flooding and engine will not start. If you do
flood engine, wait a few minutes before
attempting to start and do not repeat
priming steps.

MOWING TIPS
MULCHING MOWING TIPS
CAUTION: Do not use de-thatcher
blade attachments on your mower. Such
attachments are hazardous, will damage
your mower and could void your warranty.
• Under certain conditions, such as very
tall grass, it may be necessary to raise
the height of cut to reduce pushing effort
and to keep from overloading the engine
and leaving clumps of grass clippings.
It may also be necessary to reduce
ground speed and/or run the lawn
mower over the area a second time.
• For extremely heavy cutting, reduce the
width of cut by overlapping previously
cut path and mow slowly.
• For better grass bagging and most cutting conditions, the engine speed should
be set in the FAST position.
• Pores in cloth grass catchers can
become filled with dirt and dust with use
and catchers will collect less grass. To
prevent this, regularly hose catcher off
with water and let dry before using.
• Keep top of engine around starter clear
and clean of grass clippings and chaff.
This will help engine air flow and extend
engine life.
IMPORTANT: For best performance,
keep mower housing free of built-up
grass and trash. See “CLEANING” in the
Maintenance section of this manual.
• The special mulching blade will recut
the grass clippings many times and
reduce them in size so that as they fall
onto the lawn they will disperse into
the grass and not be noticed. Also, the
mulched grass will biodegrade quickly
to provide nutrients for the lawn. Always
mulch with your highest engine (blade)
speed as this will provide the best recutting action of the blades.
• Avoid cutting your lawn when it is wet.
Wet grass tends to form clumps and
interferes with the mulching action. The
best time to mow your lawn is the early
afternoon. At this time the grass has
dried, yet the newly cut area will not be
exposed to direct sunlight.
• For best results, adjust the lawn mower
cutting height so that the lawn mower
cuts off only the top one-third of the
grass blades. If the lawn is overgrown it
will be necessary to raise the height of
cut to reduce pushing effort and to keep
from overloading the engine and leaving
clumps of mulched grass. For extremely
heavy grass, reduce your width of cut
by overlapping previously cut path and
mow slowly.
MAX 1/3
• Certain types of grass and grass
conditions may require that an area be
mulched a second time to completely
hide the clippings. When doing a second cut, mow across (perpendicular) to
the first cut path.
• Change your cutting pattern from week
to week. Mow north to south one week
then change to east to west the next
week. This will help prevent matting and
graining of the lawn.

section of this manual.
• At least once a year, replace the spark
plug, clean or replace air filter element
and check blade for wear. A new spark
plug and clean/new air filter element
assure proper air-fuel mixture and help
your engine run better and last longer.
• Follow the maintenance schedule in this
manual.

BEFORE EACH USE
• Check engine oil level.
• Check for loose fasteners.
LUBRICATION
Keep unit well lubricated
(See “LUBRICATION CHART”).
12
IMPORTANT: Do not oil or grease plastic
wheel bearings. Viscous lubricants will
attract dust and dirt that will shorten the life of
the self-lubricating bearings. If you feel they
must be lubricated, use only a dry, powdered
graphite type lubricant sparingly.
LAWN MOWER
Always observe safety rules when performing any maintenance.
TIRES
• Keep tires free of gasoline, oil, or insect
control chemicals which can harm rubber.
• Avoid stumps, stones, deep ruts, sharp
objects and other hazards that may
cause tire damage.
DRIVE WHEELS
Check rear drive wheels each time before
you mow to be sure they move freely.
The wheels not turning freely means trash,
grass cuttings, etc. are in the drive wheel area
and must be cleaned to free drive wheels.
If necessary to clean the drive wheels, be
sure to clean both rear wheels.
BLADE CARE
For best results, blade must be kept
sharp. Replace a bent or damaged blade.
CAUTION: Use only a replacement
blade approved by the manufacturer of
your mower. Using a blade not approved
by the manufacturer of your mower is hazardous, could damage your mower and
void your warranty.
TO REMOVE BLADE
1. Disconnect spark plug wire from spark
plug and place wire where it cannot
come in contact with plug.
2. Turn lawn mower on its side. Make
sure air filter and carburetor are up.
3. Use a wood block between blade and
mower housing to prevent blade from
turning when removing blade bolt.
NOTE: Protect your hands with gloves
and/or wrap blade with heavy cloth.
4. Remove blade bolt by turning counterclockwise.
5. Remove blade & attaching hardware
(bolt, lock washer & hardened washer).
TO REPLACE BLADE
1. Position blade on the blade adapter
aligning the two (2) holes in the blade
with the raised lugs on the adapter.
2. Be sure the trailing edge of blade (opposite sharp edge) is up toward engine.
3. Install the blade bolt with the lock
washer and hardened washer into
blade adapter and crankshaft.
4. Use block of wood between blade and
lawn mower housing and tighten the
blade bolt, turning clockwise.
• The recommended tightening torque is
35-40 ft. lbs.
IMPORTANT: Blade bolt is heat treated.
If bolt needs replacing, replace only with
approved bolt shown in the Repair Parts
section of this manual.

TO SHARPEN BLADE
NOTE: We do not recommend sharpening the blade - but if you do, be sure the
blade is balanced. An unbalanced blade
will cause eventual damage to mower or
engine.
• The blade can be sharpened with a file
or on a grinding wheel. Do not attempt
to sharpen while on the mower.
• To check blade balance, drive a nail into
a beam or wall. Leave about one inch of
the straight nail exposed. Place center
hole of blade over the head of the nail.
If blade is balanced, it should remain in
a horizontal position. If either end of the
blade moves downward, sharpen the
heavy end until the blade is balanced.
GRASS CATCHER
• The grass catcher may be hosed with
water, but must be dry when used.
• Check your grass catcher often for damage or deterioration. Through normal
use it will wear. If catcher needs replacing, replace only with approved replacement catcher shown in the Repair Parts
section of this manual. Give the lawn
mower model number when ordering.
GEAR CASE
• To keep your drive system working
properly, the gear case and area around
the drive should be kept clean and free
of trash build-up. Clean under the drive
cover twice a season.
• The gear case is filled with lubricant to
the proper level at the factory. The only
time the lubricant needs attention is if
service has been performed on the gear
case.
• If lubricant is required, use only Texaco
Starplex Premium 1 Grease, Part No.
13 750369. Do not substitute.

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
NOTE: Although multi-viscosity oils
(5W30, 10W30 etc.) improve starting in
cold weather, these multi-viscosity oils will
result in increased oil consumption when
used above 32°F. Check your engine oil
level more frequently to avoid possible
engine damage from running low on oil.
Change the oil after every 25 hours of operation orat least once a year if the mower
is not used for 25 hours in one year.
Check the crankcase oil level before
starting the engine and after each five (5)
hours of continuous use. Tighten oil plug
securely each time you check the oil level.
TO CHANGE ENGINE OIL
NOTE: Before tipping lawn mower to drain
oil, empty fuel tank by running engine until
fuel tank is empty.
1. Disconnect spark plug wire from spark
plug and place wire where it cannot
come in contact with plug.
2. Remove engine oil cap; lay aside on a
clean surface.
3. Tip lawn mower on its side as shown
and drain oil into a suitable container.
Rock lawn mower back and forth to remove any oil trapped inside of engine.
AIR FILTER
Your engine will not run properly and
may be damaged by using a dirty air
filter. Replace the air filter cartridge every
100 hours of operation or every season,
whichever occurs first. Service air cleaner
more often under dusty conditions.
TO CLEAN AIR FILTER
1. Loosen screw and tilt cover to remove.
2. Carefully remove cartridge.
3. Clean by gently tapping on a flat surface. If very dirty, replace cartridge.
CAUTION: Petroleum solvents, such
as kerosene, are not to be used to clean
cartridge. They may cause deterioration
of the cartridge. Do not oil cartridge. Do
not use pressurized air to clean or dry
cartridge.
4. Install cartridge, then replace cover

CLEANING
IMPORTANT: For best performance,
keep mower housing free of built-grass
and trash. Clean the underside of your
mower after each use.
CAUTION: Disconnect spark plug wire
from spark plug and place wire where it
cannot come in contact with plug.
• Clean the underside of your lawn mower
by scraping to remove build-up of grass
and trash.
• Clean engine often to keep trash from
accumulating. A clogged engine runs
hotter and shortens engine life.
• Keep finished surfaces and wheels free
of all gasoline, oil, etc.
• We do not recommend using a garden
hose to clean lawn mower unless the
electrical system, muffler, air filter and
carburetor are covered to keep water
out. Water in engine can result in shortened engine life.
CLEAN UNDER DRIVE COVER
Clean under drive cover at least twice a
season. Scrape underside of cover with
putty knife or similar tool to remove any
build-up of trash or grass on underside of
drive cover.

ENGINE
FUEL SYSTEM
IMPORTANT: It is important to prevent
gum deposits from forming in essential
fuel system parts such as carburetor, fuel
filter, fuel hose, or tank during storage.
Alcohol blended fuels (called gasohol or
using ethanol or methanol) can attract
moisture which leads to separation and
formation of acids during storage. Acidic
gas can damage the fuel system of an
engine while in storage.
• Empty the fuel tank by starting the engine and letting it run until the fuel lines
and carburetor are empty.
• Never use engine or carburetor cleaner
products in the fuel tank or permanent
damage may occur.
• Use fresh fuel next season.
NOTE: Fuel stabilizer is an acceptable
alternative in minimizing the formation of
fuel gum deposits during storage. Add
OTHER
• Do not store gasoline from one season
to another.
• Replace your gasoline can if your can
starts to rust. Rust and/or dirt in your
gasoline will cause problems.
• If possible, store your unit indoors and
cover it to protect it from dust and dirt.
• Cover your unit with a suitable protective cover that does not retain moisture.
Do not use plastic. Plastic cannot
breathe, which allows condensation to
form and will cause your unit to rust.
IMPORTANT: Never cover mower while
engine and exhaust areas are still warm.
CAUTION: Never store the lawn
mower with gasoline in the tank inside a
building where fumes may reach an open
flame or spark. Allow the engine to cool
before storing in any enclosure.
