spillage before operating or storing the machine.
• Allow machine to cool before storage.
• Choose a low ground speed
so that you will not have to
stop while on the slope.
• Do not mow on wet grass.
Tires may lose traction.
• Avoid starting, stopping,
or turning on a slope. If
the tires lose traction,
disengage the blades and
proceed slowly straight down the slope.
• Keep movement on the slopes slow and gradual. Do not
make sudden changes in speed or direction, which could
cause machine to roll over.
• Use extra care while operating machine with grass catchers
or other attachments; they can affect the stability of the

bed with plastic liner. Always place containers on the
ground away from the vehicle when filling.
• Never overfill fuel tank. Replace gas cap and tighten
securely.
Slope Operation
Slopes are a major factor related to loss of control and tip-over
accidents, which can result in severe injury or death. Operation
on all slopes requires extra
caution. If you cannot back up
the slope or if you feel uneasy
on it, do not mow it.
• Mow up and down slopes
(10 degrees maximum), not
across.
• Watch for holes, ruts,
bumps, rocks, or other
hidden objects. Uneven terrain could overturn the machine.
Tall grass can hide obstacles.

SAFETY
• Remove gas-powered equipment from the truck or trailer
and refuel it on the ground. If this is not possible, 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.
• Do not start the engine near spilled fuel.
• Never use gasoline as a cleaning agent.
• If leaks arise in fuel system, the engine must not be started
until problem has been resolved.
• Check the fuel level before each use and leave space for
the fuel to expand, as the heat from the engine and the sun
may otherwise cause the fuel to expand and overflow.
• Never make adjustments or repairs with the engine running.
• Check the park brake’s functionality regularly. Adjust and
service as necessary.
• The blades are sharp and can cause cuts and gashes.
Wrap the blades or use protective gloves when handling
them.
• Never work with the starter circuit if there is spilled fuel.
• Ensure that the fuel filler cap is mounted tightly and no
flammable substances are stored in an open vessel.
• Sparking can occur when working with the battery and the
heavy cables of the starter
circuit. This can cause
battery explosion, fire or
eye injury. Sparking will not
occur after the grounding
cable (normally negative,
black) is removed from the
battery.
• Disconnect the grounding
cable from the battery first
and reconnect it last.
• Do not make a bridge short circuit across the starter relay
to run the starter.
• Be very careful when handling battery acid. Acid on skin
can cause serious corrosive burns. If you spill battery
acid on your skin, rinse
immediately with water.
• Acid in the eyes can cause
blindness, contact a doctor
immediately.
• Be careful when servicing
the battery. Explosive gases
form in the battery. Never
perform maintenance on the
battery when smoking or
near open flames or sparks. The battery can explode and
cause serious injury or damage.
CAUTION! Use protective glasses for
maintenance work.
General Maintenance
• Never use the machine
indoors or in spaces lacking
proper ventilation. The

CONTROLS
Steering Control Levers
WARNING! The machine can turn very rapidly if one
steering control is moved much further forward than the
other.
Park Brake
The machine’s speed and direction are continuously variable
using the two steering controls. The steering controls can
be moved forward or backward about a neutral position.
Furthermore, there is a neutral position, which is locked if the
steering controls are moved outward.
When both controls are in the neutral position (N), the machine
stands still.
By moving both controls an equal amount forward or
backward, the machine moves in a straight line forward or
backward respectively.
In order, for example, to turn right while moving forward, move
the right control towards the neutral position. The rotation of the
right wheel is reduced and the machine turns to the right.
Zero turn can be achieved by moving one control backward
(behind the neutral position) and carefully moving the other
steering control forward from its neutral position. The rotation
direction when zero turning is determined by which steering
control is moved backward behind the neutral position. If the
left steering control is pulled backward, the machine turns to
the left. Use extra care when using this maneuver.
If the steering controls are in uneven positions when standing
still or do not fit in the slots for moving the controls outward,
they can be adjusted.
The park brake is found on the right side of the machine. Pull
the lever backward to activate the brake and push forward to
release it.
IMPORTANT INFORMATION The machine must stand
absolutely still when applying the park brake. Always set
the park brake before dismounting. Release the park brake
before moving the mower.

CONTROLS
Throttle Control
Refueling
The throttle control regulates the engine speed and thereby
the rate of rotation of the blades, assuming the blade switch is
pulled out, see Engaging the Mower Deck.
To increase or decrease the engine speed, the control is
moved forward or back respectively.
Avoid idling the engine for long periods, as there is a risk
of fouling the spark plugs. USE FULL THROTTLE WHEN
MOWING, for best mower performance and battery charging.
Read the safety instructions before refueling. The machine has
one fuel tank, just behind the seat. The tank volume is 11.4
litres.
Make sure the fuel cap is properly tightened and the cap
gasket is not damaged.
The engine will run on a minimum of 85-octane unleaded
gasoline (no oil mix). Environmentally adapted alkylate
gasoline can be used. See also Technical Data concerning
ethanol fuel. Methanol fuel is not allowed. Do not use E85
alcohol based fuel. Damage to engine and components may
occur.
IMPORTANT INFORMATION Experience indicates that
alcohol blended fuels (called gasohol, 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. Drain the gas tank, start the
engine and let it run until the fuel lines and carburetor are
empty. Use fresh fuel the next season. See Storage for
additional information. Never use engine or carburetor
cleaners in the fuel tank or permanent damage may occur.
Cold Weather Start
In temperatures below 32OF, move the throttle control forward
past the start detent to the snowflake symbol. Once the engine
has started, slowly move the throttle control back to the full
throttle position.
WARNING! Gasoline is highly flammable.
Observe caution and fill the tank outdoors (see the safety
instruction).
WARNING! The engine and the exhaust system,
become very hot during operation.
Risk for burns if touched.
Allow engine and exhaust system to cool before refueling.
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.
13
CONTROLS
Fuel Shut Off Valve
Blade Control Lever
To engage the mower blades, slowly lift the lever up and into
the lock notch.
The fuel shut off valve is located in the fuel line under the
seat. Tilt seat forward for access. The fuel valve is ON when
the valve is parallel to the fuel line. Rotate the valve ¼ turn
clockwise to turn fuel OFF.
Tracking
If the mower is not tracking straight, check the air pressure
in both rear tires. Recommended air pressure is 15 psi. (1
bar) Tracking must be checked on a flat and level concrete or
blacktop surface. If the unit still does not track straight contact
your Husqvarna workshop for adjustments.
Mower Deck Lifting Lever
Bypass Linkages
Transaxle bypass linkages must be engaged when pushing or
pulling the mower. The release levers are located on each side
of the rear of the unit below the rear engine plate. See Moving
Machine By Hand in the Operation section.
The lifting lever is used to place the mower deck in the
transport position or one of the 6 different cutting height
positions.
The cutting height is set by placing a lever in the notch for the
desired cutting height.
The lifting lever can also be used to temporarily adjust the
cutting height, such as when passing a minor bump in the
lawn.
IMPORTANT INFORMATION To obtain an even cutting
height, it is important that the air pressure in all tires is 15
psi / 103 kPa / 1 bar.
WARNING! Bypass linkages are located close to
the muffler. To prevent burns, the engine should be shut off
and allowed to cool before the bypass linkage levers are
handled.
IMPORTANT INFORMATION Always raise the deck to the
highest position for transport.

2. Perform the daily maintenance before starting (see
Maintenance Schedule in the Maintenance section).
3. Check that there is sufficient fuel in the fuel tank.
4. Adjust the seat to the desired position.
Training
Due to unique steering capabilities, zero turn mowers are far
more maneuverable than typical riding mowers.
This section should be reviewed in its entirety prior to
attempting to move the mower under its own power. When
first operating the mower or until becoming comfortable with
controls, use a reduced throttle speed and reduced ground
speed. DO NOT move control levers to the furthest forward or
reverse positions during initial operation.
First time users should become familiar with the mower’s
movement on a hard surface, such as concrete or blacktop
PRIOR to attempting to operate on turf. Until the operator
becomes comfortable with the mower controls and zero turning
capability, overly aggressive maneuvers may damage turf.
The following conditions must be fulfilled before the engine
can be started:
• The blade switch must be pressed downward into the
disengaged position.
• The park brake must be up into the activated position.
• Both steering controls must be in the locked (outer) neutral
position.
Steering
To move forward and backward
The direction and speed of the mower’s movements are
effected by the movement of the control lever(s) on each side
of mower. The left control lever controls the left wheel. The right
control lever controls the right wheel.
First time users should push the mower (see Manual Transport
in the Operation section) to an open, flat area without other
people, vehicles or obstacles nearby. To move the unit under
its own power, the operator must sit in the seat and start the
engine (see Before Starting in the Operation section). Adjust
the engine speed to idle, disengage the park brake but do not
engage the blades at this time. Rotate control levers inward.
As long as the control levers have not been moved forward or
backwards, the mower will not move.
Slowly move both control levers forward slightly. This will allow
mower to start moving forward in a straight line. Pull the control
levers back to the neutral position and the mower should stop
moving.
Pull back slightly on control levers, allowing the mower to
move backwards. Push the control levers forward to the neutral
position and mower should stop moving.
To turn to the right
While moving in a forward direction, pull the right lever back
towards the neutral position while maintaining the position of
the left lever, this will slow the rotation of the right wheel and
cause the machine to turn in that direction.
To turn to the left
While moving in a forward direction pull the left lever back
towards the neutral position while maintaining the position of
the right lever, this will slow the rotation of the left wheel and
cause the machine to turn in that direction.
To zero turn
While moving in a forward direction, first pull both control
levers back until the mower stops or slows dramatically.
Then by alternating one lever slightly to the forward position
and the other in the reverse position, complete the turn.
Starting the Engine
1. Sit on the seat.
2. Raise the mower deck by pulling the lifting lever upward to
the transport position (F).
3. Activate the park brake.
15
OPERATION
4. Disengage the mower blades by lowering the blade
control lever out of the lock notch and into the down
position.
If the temperature is below 32OF, move the throttle lever
up to the cold weather (snowflake) starting position.
When the engine has started, move the throttle lever back
to full throttle detent and allow the engine to warm up for a
short period before operating the unit. Failure to move the
throttle from the cold weather starting position will result in
poor engine performance, smoke and spark plug fouling.
5. Move the steering controls outward to the locked (outer)
neutral position.
7. Open the fuel valve.
8. Press in and turn the ignition key to the start position.
6. Move the throttle lever to the full throttle position.
NOTE: There is a detent at the full throttle position to aid in
setting the control.
9. When the engine starts, immediately release the ignition
key back to the run position.
IMPORTANT INFORMATION Do not run the starter for
more than 5 seconds each time. If the engine does not
start, wait approximately 10 seconds before retrying.
10. Set the engine speed with the throttle. Allow the engine to
run at a moderate speed, approximately mid throttle, for
a short time before use. USE FULL THROTTLE WHEN
MOWING.
16
OPERATION
4. Move throttle control to full throttle.
WARNING! Engine exhaust and certain vehicle
components contain or emit chemicals considered to cause
cancer, birth defects or other reproductive system damage.
The engine exhaust contains carbon monoxide, which is a
odorless, colorless, poisonous gas. Do not use the machine
in enclosed spaces.
Running
1. Release the park brake by moving the lever downward.
5. Engage the mower blade by sliding the lever upwards and
into the lock notch.
NOTE: The mower is equipped with an operator presence
system. When the engine is running, any attempt by the
operator to leave the seat without first setting the park
brake will shut off the engine.
2. Move the steering controls inwards, out of the neutral
position (N).
3. Select the cutting height by placing the lever into the
desired notch.
WARNING! Make sure that no one is near mower
when engaging blade switch.
Make sure the work area is free from objects that could be
thrown by the rotating blades.
WARNING! Do not drive up or down hills with slopes
greater than 10 degrees. Do not drive across slopes.
17
OPERATION
Stopping the Engine
Mowing Tips
1. Disengage the mower deck by sliding the blade control
lever out of the lock notch and down into the lower
position.
• Observe and flag rocks and other fixed objects to avoid
collisions.
• Begin with a high cutting height and reduce it until the
desired mowing result is attained. The average lawn should
be cut to 64 mm during the cool season and over 76 mm
during the hot months. For healthier and better looking
lawns, mow often after moderate growth. For best cutting
performance, grass over 15 cm in height should be mowed
twice. Make the first cut relatively high, the second to the
desired height.
• The mowing result will be best with a high engine speed
(blades rotate rapidly) and low speed (rider moves slowly).
If the grass is not too long and dense, the driving speed
can be increased without negatively affecting the mowing
result.
• The finest lawns are obtained by mowing often. The lawn
becomes more even and the grass clippings more evenly
distributed over the mown area. The total time taken is not
increased as a higher operating speed can be used without
poor mowing results.
• Avoid mowing wet lawns. The mowing result is poorer
because the wheels sink into the soft lawn, clumps build,
and grass clippings fasten under the cowling.
• Hose the mower deck underside with water after each use.
When cleaning, the mower deck shall be raised into the
transport position. Make sure the mower is cooled and the
engine is off.
• Use compressed air to clean top surface of the deck.
Avoid flooding water on top surface, engine and electrical
components.
• When the mulching kit is used, it is important that the
mowing interval is frequent.
2. Raise the mower deck by pulling the lifting lever upward to
the transport position.
3. When the machine is standing still, activate the park brake
by pulling the lever backward.
If the engine has been worked hard, allow it to idle at
least 60 seconds to attain a normal operating temperature
before stopping. To prevent fouling the spark plugs, avoid
idling the engine for longer periods.
4. Move the throttle to the minimum position (tortoise
symbol). Turn the ignition key to the stop position. Never
use choke to stop the engine.
5. Move the steering controls outward.
6. Remove the key. Always remove key when leaving the
mower to prevent unauthorized use.
IMPORTANT INFORMATION Leaving the ignition switch
in any other position than OFF will cause the battery to be
discharged.
18
OPERATION
Weak Battery
Operating On Hills
If the battery is too weak to start the engine, it should be
recharged. (See Battery in the Maintenance section.)
If jumper cables are used for emergency starting, follow this
procedure:
Read the Safety Instructions Driving on Slopes in the Safety
section.
• The slowest speed possible should be used before starting
up or down hills.
• Avoid stopping or changing speed on hills.
• If stopping is absolutely necessary, pull steering controls
into the neutral position and push to the outside of the unit.
Engage the park brake.
• To restart movement, release the park brake.
• Pull the control levers back to the center of the mower and
press forward to regain forward motion.
• Make all turns slowly.
Jumper Cable Use
1. Connect each end of the RED cable to the POSITIVE (+)
terminal on each battery, taking care not to short against
chassis.
2. Connect one end of the BLACK cable to the NEGATIVE (-)
terminal of the fully charged battery.
3. Connect the other end of the BLACK cable to a good
CHASSIS GROUND on the mower with the discharged
battery, away from the fuel tank and battery.
WARNING! Never drive the rider on terrain that
slopes more than 10 degrees. Mow slopes up and down,
never side to side. Avoid sudden directional changes.
Moving Machine By Hand
When pushing or pulling the mower, be sure to engage the
EZT Hydrogear bypass linkages. The EZT bypass linkages are
located on the rear of the frame, below the rear engine guard.
1. Raise the deck into the highest cutting position.
2. Pull the EZT bypass linkages out and into the slots.
Release linkages to hold in the bypass position.
3. Release park brake.
4. To reengage the EZT’s to drive, reverse the above
procedure.
To remove cables, reverse order
1. Remove BLACK cable first from chassis and then from the
fully charged battery.
2. Remove RED cable last from both batteries.
CAUTION! Lead-acid batteries generate explosive
gases. Keep sparks, flame and smoking materials away
from batteries. Always wear eye protection when around
batteries.
IMPORTANT INFORMATION The mower is equipped
with a 12-volt negative grounded system. The other vehicle
must also be a 12-volt negative grounded system. Do not
use your mower to start other vehicles.
WARNING! Bypass linkages are located close to
the muffler. To prevent burns, the engine should be shut off
and allowed to cool before the bypass linkage levers are
handled.
WARNING! Use extreme caution when loading the
machine into a truck or trailer using ramps. There is the
possibility of serious injury or death if the machine falls off
the ramps.

MAINTENANCE
Safety System
V-belts
The machine is equipped with a safety system that prevents
starting or driving under the following conditions.
The engine can only be started when:
• The mower deck is disengaged.
• The steering controls are in the outer, locked neutral
position.
• The park brake is on.
Make daily inspections to ensure that the safety system works
by attempting to start the engine when one of the conditions is
not met. Change the conditions and try again.
If the machine starts when one of these conditions is not met,
turn the machine off and repair the safety system before using
the machine again.
Make sure the engine stops when the park brake is not
engaged and the operator leaves the seated position.
Check that the engine stops if the mower blades are engaged
and the driver temporarily moves off the drivers seat.
Check every 100 hours of operation. Check for severe
cracking and large nicks.
NOTE: The belt will show some small cracks in normal
operation.
The belts are not adjustable. Replace belts if they begin to slip
from wear.
Deck Belt

1. Park on a level surface. Apply park brake.
2. Lower the deck to the lowest cutting position.
3. Disengage the clutch by sliding the blade control lever
downwards.
IMPORTANT INFORMATION To be able to drive, the
driver must sit in the seat and release the park brake
before the steering controls can be moved into the neutral
position, otherwise the engine will stop.
EZT Belt
4. Carefully lift the belt away from belt keepers and off deck
pulleys and remove from deck.
To replace EZT belt
Park the mower on a level surface. Engage the park brake.
EZT belt removal
NOTE: Be careful not to damage the fan blades on the EZT as
this can affect cooling or damage the EZT.
1. Remove the deck belt (see To replace deck belt in this
section of the manual).
2. Create slack in the belt by pushing the spring loaded idler
arm inward. Rotate arm to release belt tension.
3. The belt should now be able to be removed from the
engine pulley and EZT pulleys.
Belt installation

The sharpening of blades should be carried out by
an authorized service workshop.
22
MAINTENANCE
Tire Pressures
Cutting Blades
All tires should be at 15 psi / 103 kPa / 1 bar.
To attain the best mowing effect, it is important that blades are
well sharpened and not damaged.
Replace blades that have been bent or cracked when hitting
obstacles.
Let the service workshop decide whether a blade with large
nicks can be repaired/ground or must be replaced. Balance
the blades after sharpening.
Check the blade mounts.
Blade Replacement
1. Remove blade bolt by turning counterclockwise.
2. Install new or resharpened blade with stamped GRASS
SIDE facing towards ground/grass (down) or THIS SIDE
UP facing deck and cutter housing.
IMPORTANT INFORMATION DO NOT add any type of
tire liner or foam fill material to the tires. Excessive loads
created by foam filled tires will cause premature failures.
Only use O.E.M. specified tires.
Caster Wheels
Check every 200 hours. Check that wheels rotate freely. If
wheels do not rotate freely take the unit to your dealer for
service.
Foam filled tires or solid tires will void the warranty.
Removal and installation of caster wheel
1. Remove nut and caster bolt.
2. Pull the wheel out of the fork and take care of the sleeve.
3. Reinstall in reverse order. Tighten caster bolt.
3. Seat the blade's opening firmly onto the cutter housing.
4. Tighten blade bolt securely.
5. Torque blade bolt to 50 ft/lbs (67 Nm).
IMPORTANT INFORMATION Special blade bolt is heat
treated. Replace with a Husqvarna bolt if required. Do not
use lower grade hardware than specified.
23
MAINTENANCE
Adjusting the Mower Deck
Cleaning
Regular cleaning and washing, especially under the mower
deck, will increase the machine’s life-span. Make it a habit to
clean the machine directly after use (after it is cooled), before
the debris sticks.
Use compressed air to clean the top side of mower deck. For
cleaning the underside of the deck, use the cleanout port.
CAUTION! Blades are sharp. Protect your hands
with gloves and/or wrap blades with a heavy cloth
when handling.
Check the tire pressure before adjustment of the mower deck.
See Tire Pressures in Maintenance. Faulty mower deck
adjustments will cause an uneven mowing result.
Leveling Deck
1. Position the mower on a level, preferably concrete,
surface.
2. Check the pressure in all four tires. See Technical Data
section.
3. Rotate blade to align side to side.
Attach the quick connect (from the accessory packet) to any
garden hose. After mowing, snap the hose to the cleanout port
and turn on water.
Restart the mower and engage the blades to use the spinning
action to wash away debris. Make sure the hose is away from
the mower blades.
Avoid spraying water on the engine and electrical components.
4. Measure from the floor surface up to the bottom of the
blade tip on the discharge side of the mower deck.
Record the measurement.
5. Move to the opposite side, check that measurement is the
same. If adjustment is required turn front adjuster nut(s) to
level deck side to side.
CAUTION! Use protective glasses when cleaning
and washing.
Hardware
Check daily. Inspect the entire machine for loose or missing
hardware.
WARNING! The engine and the exhaust system,
become very hot during operation. Risk for burns if
touched. Allow engine and exhaust system before
servicing.
NOTE: This will place the mower deck in a standard
measurement position. Depending on the type of grass
being mowed or environmental conditions, additional
adjustments may be required to achieve the desired cut.

Steering Control Shafts
Tip the driver’s seat. Lubricate with a grease gun, one zerk
for each steering control shaft with good quality molybdenum
disulphide grease, until the grease is forced out.
Level check
General
Remove the ignition key to prevent unintentional movements
during lubrication.
When lubricating with an oil can, it must be filled with engine
oil.
When lubricating with grease, unless otherwise stated, use a
high grade molybdenum disulphide grease.
For daily use, the machine should be lubricated twice weekly.
Wipe away excess grease after lubrication.
It is important to avoid getting lubricant on the belts or the
drive surfaces on the belt pulleys. Should this happen, attempt
to clean them with spirits. If the belt continues to slip after
cleaning, it must be replaced. Gasoline or other petroleum
products must not be used to clean belts.
Use only good quality bearing grease. Grease from wellknown brand names (petrochemical companies, etc.) usually
maintains a good quality.
Deck Spindle
Lower the cutting deck completely. If a grease gun without
rubber hose is uses, remove the foot plate to access deck
spindle zerk. Lubricate with a grease gun, one zerk, 2-3
strokes with good quality bearing grease.
IMPORTANT INFORMATION Use minimal lubrication
and remove excess lubricant so that is does not come into
contact with belts or belt pulley drive surfaces.
Transmission
The transmission is maintenance free with no need for level
checks or oil changes. If a leak occurs, replace the unit or
contact your Husqvarna dealer.
Engine
Refer to the engine manufacturer's manual for maintenance
and service instructions.

STORAGE
Winter Storage
To ready the machine for storage:
1. Thoroughly clean the machine, especially under the
mower deck. Touch up damage to the paint and spray
a thin layer of oil on the underside of the mower deck to
avoid corrosion.
2. Inspect the machine for worn or damaged parts and
tighten any nuts or screws that may have become loose.
3. Change the engine oil; dispose of properly.
4. Empty the fuel tanks or add a fuel stabilizer. Start the
engine and allow it to run until the carburetor is drained of
fuel or the stabilizer has reached the carburetor.
5. Remove the spark plug and pour about a tablespoon of
engine oil into the cylinder. Turn over the engine so that
the oil is evenly distributed and then refit the spark plug.
6. Lubricate all grease zerks, joints, and axles.
7. Remove the battery. Clean, charge, and store the battery
in a cool place, but protect it from direct cold.
8. Store the machine in a clean, dry place and cover it for
extra protection.
The machine should be readied for storage at the end of the
mowing season or if it will not be in use for more than 30 days.
Fuel allowed to stand for long periods of time (30 days or
more) can leave sticky residues that can plug the carburetor
and disrupt engine function.
Fuel stabilizers are an acceptable option as regards to the
sticky residues that can occur during storage.
Add stabilizer to the fuel in the tank or in the storage container.
Always use the mixing ratios specified by the manufacturer
of the stabilizer. Run the engine for at least 10 minutes after
adding the stabilizer so that it reaches the carburetor. Do not
empty the fuel tank and the carburetor if you have added
stabilizer.
WARNING! Never store an engine with fuel in the
tank indoors or in poorly ventilated spaces where fuel vapor
can come in contact with open flames, sparks, or a pilot
light such as in a boiler, hot water tank, clothes dryer, etc.
Handle the fuel with care. It is very flammable and can
cause serious personal injury and property damage. Drain
the fuel into an approved container outdoors and store far
away from open flame or sources of ignition. Never use
gasoline for cleaning. Use a degreaser and warm water.
Service
When ordering spare parts, please specify the purchase year,
model, type, and serial number.
Always use genuine Husqvarna spare parts.
An annual check-up at an authorized service workshop is a
good way to ensure that your machine performs its best the
following season.
