INTRODUCTION
Introduction
Congratulations
Thank you for purchasing a Husqvarna Walk-BehindMower. This machine is built for the greatestefficiency
and rapid mowing primarily of large areas. Controls in one place and a transmission regulated by motion
controls contribute to the machine’s performance.
This manual is a valuable document. Following the instructions (use, service, maintenance, etc.)
can considerably increase the l ifespan of your machine and even increase its resale value.
If you sell your machine, be sure to give this Operator’s Manual to the new owner.
The final chapter of this Operator ’s Manual comprises a Service Journal. Ensure that service and repair
work is documented. A well kept service journal reduces service costs for the season-based maintenance
and affects the machine’s resale value. Take the Operator’s Manual along when the machine is left to the
workshop for service.
General
In this Operator’s Manual, left and right, backward and forward are used in relation to the machine’s normal
driving direction.
Driving and Transport on Public Roads

SAFETY INSTRUCTIONS
Driving on Slopes
Driving on slopes is one of the operations
where the risk is greatest that the driver will
lose controlor the machine willtip over,which
can result in serious injury or death. All
slopes require extra caution. If you cannot
reverse up a slope or if you feel unsure,
do not mow the slope.
Do as follows
•Remove obstacles such as stones,
tree branches, etc.
•Watch out for and avoid driving over
furrows, holes, and bumps. On uneven
terrain, the machine can tip more easily.
Long grass can hide obstacles.
•Mow up and down, not side-to-side.
•If machine stops while going uphill,
disengage blades and back down slowly.
•Drive evenly and slowly. Use small
movements of the motion controls.
•Be extra cautious with any additional
equipment, which can alter the
machine’s stability.
Do not
•Do not make sudden changes in speed
or direction.
•Do not drive the machine on terrain that
slopes more than 10°.
•Do not mow near verges, ditches, or
banks. The machine can suddenly spin
around if a wheel goes over the edge of
adroporditch,orifanedgegivesway.
•Do not mow wet grass. It is slippery,and
the tires can lose their grip, so that the
machine slides.
•Avoid unnecessary turns on slopes, and
if it proves necessary, turn slowly and
gradually downward, if possible.
8011-634
Mow up and down, not side-to-side
8011-635
Be extra cautious when driving on slopes
•Avoid starting or stopping on a slope. If
the tires begin to slip, shut off the blades
and drive slowly straight down the slope.

SAFETY INSTRUCTIONS
Children
•Serious accidentsmay occur if you fail to
be on guard f or children in the vicinity of
the machine.Children are often attracted
to the machine and mowing work. Never
assume that children will stay where you
last saw them.
•Keepchildrenawayfromthemowing
area and under close supervision by
another adult.
•Keep an eye out and shut off the
machine if children enter the work area.
•Beforeand duringa reversingmaneuver,
look backward and downward for small
children.
•Never allow a child to ride with you.
They can fall off and injure themselves
seriously or prevent risk-free
maneuvering of the machine.
•Never allow children to operate the
machine.
•Be particularly cautious near corners,
bushes, trees, or other objects that block
your view.

Maintenance
WARNING!
The engine must not be started when the protective plate for the mower deck’s
drive belt is removed.
•Stop the engine. Prevent the enginefrom
starting by removing the spark plug
cables from the spark plugs or by
removing the ignition key before making
any adjustments or performing
maintenance.
•Never fill the fuel tank indoors.
•Fuel and fuel fumes are poisonous and
extremely flammable. Be especially
cautious when handling fuel, as
carelessness can result i n personal

never fill the fuel tank while the engine is
running.
•Allow the engine to cool before refueling.
Do not smoke. Do not fill fuel in the
vicinity of sparks or open flames.
•If leaks arise in the fuel system, the
engine must not be started until the
problem has been resolved.
•Store the machine and fuel in such a way
that there is no risk of leaking fuel or fuel
vapor leading t o damages.
•Check the fuel level before each use and
leave space for the fuel to expand,
because the heat from the engine and
the sun may otherwise cause the fuel to
expand and overflow.
•Avoid overfilling. If you spill fuel on the
machine,wipe up the spill and wait untilit
has evaporated before starting the
engine. If you have spilled fuel on your
clothing, change your clothing.

3. Motion contro l levers
The machine’s speed and direction are
continuously variable using the two motion
control levers.
When both controls are in the neutral
position, the machine stands still. The
controls can be locked in neutral position by
the thumb latches.
By releasing both controls an equal amount,
the machine moves in a straight line forward.
WARNING!
The machine can turn very
rapidly if one motion control
lever is moved much further
than the other.
In order, for example, to turn right while
moving forward, move the right control
towards the handle (neutral position). The
rotation of the right wheel is reduced and the
machine turns to the right.
8011-660
Motion control lever
With the opposite wheel still under power a
turn is accomplished. If the motion control
lever is squeezed even tighter the brake w ill
be applied to that wheel and a tighter more
abrupt turn is accomplished.
4. Operator Presence Lever
Located on the handle. As an additional
safety feature, these mowers are equipped
with an Operators Presence System. This is
an electrical interlock safety system which is
activated by depressing either one or both of
the Operator Presence Levers towards the
handle grips.
Releasing both Operators Presence Levers
while mowing or transporting will break the
electrical circuit and cause the engine and
mower to stop. The mower will not stop
immediately after releasing the operate
presence levers, some travel does occur.
One or both levers must be pressed against the
handle for the engine to remain running, when the
blades are engaged or thumb latches are not locked
in the motion control levers.

5. Choke and Throttle Control
Choke Control
The choke control is combined with the
throttle control. To engage the choke, the
throttle control is moved past the max rpm
setting to i ts choke position.
Do not use the choke when starting a warm
engine.
Throttle Control
The throttle control regulates the engine
speed and thereby the rate of r otation of the
blades,assuming the control forengaging the
mower deck is pulled forward, see Engaging
the Mower Deck.
In order to increase or decrease the engine
speed, the control is moved downward or
upward respectively.
8011-709
Choke and throttle control
Avoid idling the engine for longer periods, as
there is a risk of the spark plugs fouling.
USE FULL THROTTLE WHEN MOWING,for
best mower performance.

9. Refueling
The machine has one fuel tank. The tank
volume is 5.3 Gallons / 20 liters.
The engine should be run on a minimum of
87-octane unleaded gasoline (no oil mix).
See “Technical data” on page 60 concerning
methanol and ethanol fuels.
WARNING!
Gasoline is highly flammable.
Observe caution and fill the
tank outdoors
(see the safety rules).
WARNING!
Fill to bottom of filler neck. Do
not overfill. Wipe off any
spilled oil or fuel. Do not store,
spill or use gasoline near an
open flame.
When operating in temperatures below 32° F.
(0°C.), use fresh, clean wintergrade gasoline
to help insure good cold weather starting.
8011-418
Fuel tank
IMPORTANT INFORMATION
Experience indicates that 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 st orage. To avoid engine
problems, the fuel system should be
emptied before storage of 30 days or
longer. Drain the gas tank, start the
engine and let it the run until the fuel
lines and carburetor are empty. Use fresh
fuel the next season. See Storage
Instructions for additional information.
Never use engine or carburetor cleaners
in the fuel tank or permanent damage
may occur.
