DRIVING
Cutting tips
WARNING! Clear the lawn from stones and
other objects which can be thrown out by
the blades.
!
•
•
•
Localise and mark stones and other fixed objects to avoid
collision.
Start with a high cutting height and reduce down until the
required mowing results are obtained.
The mowing result will be best with the highest permitted
engine speed, see technical data, (the blades rotate
rapidly) and low speed (the Rider moves slowly). If the
grass is not too high and thick, the driving speed can be
increased without noticeably depreciating the mowing
result.
•
The best lawns are achieved if the grass is cut often.
Mowing becomes more uniform and the grass cuttings
become more evenly distributed over the surface. The
total time consumption is not greater since it is possible to
select a higher driving speed without inferior mowing
results.
•
•
Avoid mowing a wet lawn.The mowing results are inferior
since the wheels sink down into the soft lawn.
Hose down the cutting unit with water underneath each
time it is used. The cutting unit should then be put in the
service position.
•
When the BioClip function is used, it is very important that
the mowing interval is not too long.
WARNING! Do not use the machine on

Open the engine cover.
Replace the air filter as follows:
Unscrew the filter cover and remove the paper filter.
•
•
Open the engine cover.
Cleaning the air filter
Loosen the two fasteners holding the filter cover and
remove it.
If the engine seems to lack power or does not run smoothly
this may be because the air filter is clogged. When driving
with a dirty air filter the engine can suffer from lack of air, so
that it does not meet environmental requirements and the
engine does not provide full power.
IMPORTANT INFORMATION
Never run the engine without the air filter fitted.
Poorly filtered inlet air is a main factor contributing to engine
wear. Replace the air filter according to the service
schedule or more often in dusty conditions
Emptying the particle collector
The filters must not be oiled. They must be fitted dry.
Remove the filter cartridge from the filter housing.
Squeeze so that the rubber tabs open and the particles can
escape.

Maintenance
•
Remove the filler cap.
Change coolant
Correct coolant level is important for the cooling system to
function properly. Therefore the coolant level must be
checked regularly.
The coolant should be visible when the filler cap is removed.
Fill only with antifreeze and water mixed according to the
following table.
Glycol
60 %
50 %
40 %
Water
40 %
50 %
60 %
Freezing point
-47 °C / -53 °F
-37 °C / -35 °F
-25 °C / -13 °F
Repeated coolant loss normally indicates leakage. The
cooling system should be checked by a professional. It is not
sufficient just to top up with coolant.
IMPORTANT! Never add cold coolant to a hot engine. Risk
of comprehensive engine damage.
If the engine boils, coolant will be lost. Open the radiator cap
and allow the coolant to cool down. Allow the engine cool
before filling.
•
Check the coolant when the engine has run for a few
minutes after filling. There may have been air in the
system that has been released.
The cooling system must not be filled with salt water, as this
will cause corrosion damage to the engine.
Replace coolant if it is discoloured or cloudy
The cooling system must then be thoroughly flushed.
Use only glycol-based antifreeze approved to BS 6580:1992
or ASTM D 3306-89 or AS 2108-1977 (indicated on the
packaging).
The antifreeze must be intended for alloy engines.
Your Husqvarna supplier can provide the right type of
antifreeze.
Use antifreeze all year round and even in climates where
there is no risk of frost.
Antifreeze contains additives that protect the engine cooling
system against corrosion
The coolant and antifreeze should be changed at least every
two years.
WARNING! Do not open the cap quickly
when the engine is hot without first
releasing the pressure by partially opening
the cap. Risk of burns. Wear protective
gloves and goggles.
!
WARNING! Antifreeze and coolant are
dangerous to health. Keep them in storage
in labelled containers and away from
children and animals.

Lubrication
Check the oil level in the
transmission gearboxes
Lubricating the cables
Remove the cable´s rubber casing when lubricating.
Grease both ends of the cables and move the controls to end
stop positions when lubricating.
•
Use the oil dipstick to check that there is oil in the
transmission.
Re-attach the rubber covers on the cables after lubrication.
Cables with sheaths will jam if they are not lubricated
regularly. A jammed cable may cause malfunction, such as
the parking braking being applied. If a cable binds, remove
the cable and hang it vertically. Lubricate it with thin engine oil
until the oil begins to escape from the bottom.
A tip: Fill a small plastic bag with oil and tape it so that it seals
against the casing and allow the cable to hang vertically from
the bag overnight. If you do not succeed in lubricating the
cable, it must be replaced.

Storage
Winter storage
Service
At the end of the season, or if the machine is going to stand
idle for more than 30 days, it should immediately be made
ready for storage. Fuel which is left to stand for long periods
(30 days or more) can leave sticky deposits and interfere with
the engine function.
Low season is the most suitable time to perform a service or
overhaul of the machine in order to ensure high function
safety during high season.
When ordering spare parts state your machine’s purchase
year, model, type, and serial number.
Fuel stabiliser is an acceptable alternative to avoid tacky
deposits during storage. Add stabiliser to the fuel in the tank
or the storage container. Always use the mixing ratios
indicated by the manufacturer. Run the engine for at least 10
minutes after adding the stabiliser.
Always use genuine parts.
An annual check-up by an authorised servicing dealer is a
good way to ensure that your ride-on mower performs at its
best the following season.
WARNING! Never store a machine with fuel
in the tank indoors or in poorly ventilated
spaces where fuel vapour can come in
!
contact with open flames, sparks, or a pilot
light such as in a boiler, hot water tank,
clothes drier, etc. Exercise caution when
handling fuel. It is highly inflammable, and
careless use can cause serious injury and
damage to property. Drain off the fuel in an
approved container outdoors and well clear
of naked flames. Never use petrol for
cleaning purposes. Use degreasing agents
and hot water instead.
To prepare the machine for storage follow these instructions:
1
Carefully clean the machine, especially under the cutting
unit. Touch-up paint damage to avoid rust.
2
Inspect the machine for worn or damaged parts and
tighten loose screws and nuts.
