SAFETY RULES  
Do not operate the mower without proper guards,  
plates, grass catcher or other safety protective  
devices in place.  
Safe handling of gasoline  
To avoid personal injury or property damage, use extreme  
care in handling gasoline. Gasoline is extremely  
flammable and the vapors are explosive.  
See manufacturer’s instructions for proper operation  
and installation of accessories. Only use accessories  
approved by the manufacturer.  
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 the 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.  
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 fuelling is  
complete. Do not use a nozzle lock-open device.  
If fuel is spilled on clothing, change clothing  
immediately.  
Stop blade when crossing gravel surfaces.  
Never leave a running machine unattended.  
Stop the engine (motor) and wait until the blade  
comes to a complete stop before cleaning the  
machine, removing the grass catcher, or unclogging  
the discharge chute.  
Mow only in daylight or good artificial light.  
Do not operate the machine while under the influence  
of alcohol or drugs.  
Never operate machine in wet grass. Always be sure  
of your footing: keep a firm hold on the handle, walk,  
never run.  
Disengage drive system, if so equipped, before  
starting the engine (motor).  
If the equipment should start to vibrate abnormally,  
stop the engine (motor) and check immediately for the  
cause.Vibration is generally a warning of trouble.

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.  
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, never up and down.  
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.

PRESENTATION  
Dear customer!  
The Lawn mower  
Congratulations on your choice to buy a Husqvarna  
product! Husqvarna is based on a tradition that dates  
back to 1689, when the Swedish King Karl XI ordered the  
construction of a factory on the banks of the Huskvarna  
River, for production of muskets.The location was logical,  
since water power was harnessed from the Huskvarna  
River to create the water-powered plant. During over 300  
years of continuous operation, the Husqvarna factory has  
produced a lot of different products, from wood stoves to  
modern kitchen appliances, sewing machines, bicycles,  
motorcycles etc. In 1956, the first motor driven lawn  
mowers appeared, followed by chain saws in 1959, and it  
is within this area Husqvarna is working today.

MACHINE´S SAFETY EQUIPMENT  
Rear deflector  
General  
The rear deflector, attached between the rear wheels of  
your mower, is provided to minimize the possibility that  
objects will be thrown out of the rear of the mower into the  
operator’s mowing position.  
This section describes the machine's safety equipment,  
its purpose, and how checks and maintenance should be  
carried out to ensure that it operates correctly.  
WARNING! Never use a machine that  
has faulty safety equipment! If your  
machine fails any checks contact your  
service agent to get it repaired.  
!
Prevent unintentional starting by  
removing the ignition cable from the  
spark plug.  
Operator presence control bar  
IMPORTANT! Federal regulations require an engine  
control to be installed on this lawn mower in order to  
minimize the risk of blade contact injury. Do not under  
any circumstances attempt to defeat the function of the  
operator control.The blade turns when the engine is  
running.  
Inspecting the rear deflector  
The operator presence control is designed to stop the  
engine.When the grip on the operator presence control  
bar is released the engine should stop.  
Make sure the rear deflector is not damaged and that  
there are no visible defects such as cracks, or broken  
springs that force the door closed. Replace the  
deflector or springs if damaged.  
Checking the operator presence control bar  
Start the engine and then release the operator  
presence control bar.The engine should stop.  
Muffler  
WARNING! Never use a machine without  
a muffler, or with a faulty muffler. A  
damaged muffler may substantially  
increase the noise level and the fire  
hazard. Keep fire fighting equipment  
handy.  
!
The muffler gets very hot during and  
after use.This also applies during idling.  
Be aware of the fire hazard, especially  
when working near flammable  
substances and/or vapours.  
The muffler is designed to keep noise levels to a minimum  
and to direct exhaust fumes away from the user.  
Inspecting the muffler  
Check regularly that the muffler is complete and  
secured correctly.

handle of the frame is outside of the top of the bag.  
The mulching mode will recut the grass clippings many  
times, which will reduce the clippings in size so that as  
they fall onto the lawn they will disperse into the grass and  
not be noticed. In addition, the mulched grass will  
biodegrade quickly to provide nutrients for the lawn.  
Use rear bagging to collect the grass clippings within the  
grass catcher.

FUEL HANDLING  
If the machine is leaking fuel. Check regularly for  
leaks from the fuel cap and fuel lines.  
General  
WARNING! Running an engine in a  
confined or badly ventilated area can  
result in death due to asphyxiation or  
carbon monoxide poisoning.  
Engine oil  
!
CAUTION! Check the oil level before starting the lawn  
mower. A too low oil level can cause serious damage to  
the engine.  
Fuel and fuel fumes are highly  
inflammable and can cause serious  
injury when inhaled or allowed to come  
in contact with the skin. For this reason  
observe caution when handling fuel and  
make sure there is adequate ventilation.  
See instructions in the section “Maintenance”.  
Transport and storage  
Store and transport the machine and fuel so that there  
is no risk of any leakage or fumes coming into contact  
with sparks or open flames, for example, from  
electrical machinery, electric motors, electrical relays/  
switches or boilers.  
The exhaust fumes from the engine are  
hot and may contain sparks which can  
start a fire. Never start the machine  
indoors or near combustible material!  
When storing and transporting fuel always use  
approved containers intended for this purpose.  
Do not smoke and do not place any hot  
objects in the vicinity of fuel.  
Long-term storage  
When storing the machine for long periods the fuel  
tank must be emptied. Contact your local gas station  
to find out where to dispose of excess fuel.  
Fueling  
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  
Fuel stabilizer is an acceptable alternative to avoid  
tacky deposits during storage. Add stabilizer to the  
fuel in the tank or the storage container. Always follow  
the mix ratio found on stabilizer container. Run the  
engine for at least 10 minutes after adding the  
stabilizer so that it will reach the carburetor. Do not  
empty the gas tank and carburetor if using fuel  
stabilizer.  
WARNING! Always stop the engine and  
let it cool for a few minutes before  
!
refueling.The engine should be  
switched off.  
Use a fuel can at all times to avoid  
spillage.  
CAUTION! Alcohol blended fuels (called gasohol or  
using ethanol or methanol) can attract moisture which  
leads to separation and formation of acids during  
storage.  
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.  
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. Never use engine or carburetor  
cleaner products in the fuel tank or permanent damage  
may occur.  
When refuelling, open the fuel cap  
slowly so that any excess pressure is  
released gently.  
Clean the area around the fuel cap.  
Tighten the fuel cap carefully after  
refueling. Negligence may lead to the  
start of a fire.  
Never start the machine:  
If you have spilled fuel or engine oil on the machine,  
wipe off the spillage and allow remaining fuel to  
evaporate.  
If you have spilled fuel on yourself or your clothes,  
change your clothes.Wash any part of your body that  
has come in contact with fuel. Use soap and water.

OPERATING  
Always use common sense  
Work area safety  
It is not possible to cover every conceivable situation you  
can face. Always exercise care and use your common  
sense. If you get into a situation where you feel unsafe,  
stop and seek expert advice. Contact your dealer, service  
agent or an experienced user. Do not attempt any task  
that you feel unsure of!  
Branches, twigs, stones, etc. should be removed from  
the lawn before you start to mow.  
Objects hitting against the cutting attachment could  
be thrown and cause damage to people and objects.  
Keep people and animals well away.  
Never use the machine in bad weather, for instance in  
fog, in rain, damp or in wet locations, strong winds,  
intense cold, risk of lightning, etc.Working in bad  
weather is tiring and can lead to dangerous  
conditions, e.g. slippery surfaces.

OPERATING  
Pay particular attention when pulling the machine  
towards you during work.  
Slope operation  
Mowing slopes can be dangerous. Do not use the lawn  
mower on slopes steeper than 15°. All slopes demand  
extra care. If you feel unsure, do not mow it.  
Never lift up the lawn mower or carry it around when  
the engine is running. If you must lift the lawn mower,  
first switch off the engine and disconnect the ignition  
lead from the spark plug.  
Do:  
Mow across the face of slopes, never up and down.  
Do not mow the lawn while walking backwards.  
Exercise extreme caution when changing direction on  
slopes.  
The engine should be switched off when moving over  
ground that is not to be mowed. For example, gravel  
paths, stone, shingle, asphalt, etc.  
Remove obstacles such as stones, branches, etc.  
Never run with the machine when it is running.You  
should always walk with the lawn mower.  
Watch for holes, ruts, bumps or hidden objects.  
Uneven terrain could cause a slip and fall accident.  
Tall grass can hide obstacles.  
Shut down the engine before changing the cutting  
height. Never make adjustments with the engine  
running.  
Do not:  
Do not mow too close to edges, ditches or banks.  
Never leave the machine unsupervised with the motor  
running.Turn off the motor. Ensure the cutting  
attachment has stopped rotating.  
Avoid sudden changes in direction.  
Do not mow wet grass. It is slippery, and tires can lose  
their grip so that the machine skids.  
If any foreign object is hit or if vibrations occur stop the  
machine immediately. Disconnect the spark plug wire  
from the spark plug. Check that the machine is not  
damaged. Repair any damage.  
Transport and storage  
Secure the equipment during transportation in order  
to avoid transport damage and accidents.  
Never direct discharged material toward anyone.  
Avoid discharging material against a wall or  
obstruction. Material may richochet back toward the  
operator.  
Store the equipment in a lockable area so that it is out  
of reach of children and unauthorized persons.  
Store the machine and its equipment in a dry and frost  
proof place.  
Basic working techniques  
Always cut with a sharp blade for optimal results. A  
dull blade gives an uneven cut and the grass becomes  
yellow on the surface of the cut.  
When loading or unloading this machine, do not  
exceed the maximum recommended operation angle  
of 15°.  
Never mow more than 1/3 of the length of the grass.  
This especially applies during dry periods. Mow first  
with the cutting height set high.Then check the result  
and lower to an appropriate height. If the grass is  
really long, drive slowly and mow twice if necessary.  
Empty the fuel tank by running the machine until the  
tank is empty.  
Drain the engine oil as described under Changing the  
engine oil.  
Clean the machine. For more information, see the  
”Cleaning” section.  
MAX 1/3  
Lubricate as shown in the Maintenance section of this  
manual.  
Tighten bolts and nuts.  
Replace or repair damaged components.  
Touch up all rusted or chipped paint surfaces, sand  
lightly before painting.  
For extremely heavy cutting, reduce the width of cut  
by overlapping previously cut path and mow slowly.  
Place the lawn mower in Transport position. See  
”Storage/Transport position” in the Assembly and  
adjustments section of this manual.  
Cut in different directions each time in order to avoid  
stripes in the lawn.  
Before pulling the machine towards you, disengage  
the drive and push the machine forward approx. 3’’ (10  
cm).  
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. Never cover mower  
while engine and exhaust areas are still warm!  
Make sure to disengage the drive when approaching  
an obstacle.  
For transport and storage of fuel, see the section  
“Fuel handling”.  
Pores in cloth grass catchers can become filled with dirt  
and dust with use and the catcher will collect less grass.  
To prevent this, regularly hose the grass catcher off with  
water and let dry before using.

MAINTENANCE  
General recommendations  
Cleaning  
The warranty on this lawn mower does not cover items  
that have been subjected to operator abuse or  
negligence.To receive full value from the warranty,  
operator must maintain mower as instructed in this  
manual. Some adjustments will need to be made  
periodically to properly maintain your unit. At least once  
a season, check to see if you should make any of the  
adjustments described in the Maintenance section of  
this manual.  
WARNING! Always disconnect the  
spark plug before performing  
maintenance or service.  
!
Brush leaves, grass and the like off of the lawn  
mower.  
Keep finished surfaces / wheels free of gasoline, oil,  
etc.  
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.  
Keep top of engine around starter clear and clean  
of grass clippings and chaff.This will help engine air  
flow and extend engine life.  
Clean the underside of your lawn mower by  
scraping to remove build-up of grass and trash.  
Follow the maintenance schedule in this manual.  
Do not use a high pressure washer to clean the  
machine.  
General inspection  
Never flush water directly on the engine.  
Check that nuts and screws are tight.  
Clean the air intake on the starter. Check the starter  
and starter cord.  
General lubrication  
When cleaning under the cutting cover, empty the fuel  
tank and put the machine on its side with the muffler  
down.  
CAUTION! 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.  
CAUTION! With the exception of the water washout  
port (if equipped), we do not recommend using a  
garden hose to clean the outside of your 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.  
Keep unit well lubricated.
