SERVICE WORK ON THE ENGINE
17
Danger
Danger of poisoning Exhaust gases are toxic and
inhaling them may result in unconsciousness and
death.
- Always make sure there is sufficient ventilation
when running the engine.
- Use effective exhaust extraction when starting or
running the engine in an enclosed space.
- Start the engine and check it for leaks.
Finishing work
- Check the engine oil level. ( p. 118)
17.4
Adding engine oil
Info
Too little engine oil or poor-quality engine oil will result in premature wear of the engine.
Main work
- Remove filler plug 1 with the O-ring.
- Add the same engine oil used when the last oil change was
carried out.
Engine oil (SAE 10W/50) ( p. 140)
Info
For optimal performance of the engine oil, do not mix
401955-10
different types of engine oil.
Husqvarna Motorcycles recommends changing the
engine oil.
- Mount and tighten the filler plug together with the O-ring.

CLEANING, CARE
18.1
Cleaning the motorcycle
Note
Material damage Components become damaged or destroyed if a pressure cleaner is used incorrectly.
The high pressure forces water into the electrical components, connectors, throttle cables, and bearings, etc.
Pressure which is too high causes malfunctions and destroys components.
-
Do not direct the water jet directly on to electrical components, connectors, throttle cables or bearings.
–
Maintain a minimum distance between the nozzle of the pressure cleaner and the component.
Minimum clearance
60 cm (23.6 in)
Note
Environmental hazard Hazardous substances cause environmental damage.
- Dispose of oils, grease, filters, fuel, cleaning agents, brake fluid, etc., correctly and in compliance
with the applicable regulations.
Info
To maintain the value and appearance of the motorcycle over a long period, clean it regularly.
Avoid direct sunshine when cleaning the motorcycle.
-
Close off exhaust system to keep water from entering.
–
Remove loose dirt first with a soft jet of water.
–
Spray the heavily soiled parts with a normal commercial
motorcycle cleaner and clean using a brush.
Motorcycle cleaner ( p. 142)
Info
Use warm water containing normal motorcycle cleaner
401061-01
and a soft sponge.
Never apply motorcycle cleaner to a dry vehicle;
always rinse the vehicle with water first.
-
After rinsing the motorcycle with a gentle spray of water,
allow it to dry thoroughly.
-
Remove the closure of the exhaust system.
Warning
Danger of accidents Moisture and dirt impair the
brake system.
- Brake carefully several times to dry out and
remove dirt from the brake linings and the brake
discs.
-
After cleaning, ride the vehicle a short distance until the
engine warms up.
Info
The heat produced causes water at inaccessible loca-
tions in the engine and on the brake system to evapo-
rate.
-
Push back the protection caps of the handlebar controls to
allow any water that has penetrated to evaporate.
122
CLEANING, CARE
18
– After the motorcycle has cooled down, lubricate all moving
parts and pivot points.
- Clean the chain. ( p. 72)
- Treat bare metal (except for brake discs and the exhaust sys-
tem) with a corrosion inhibitor.
Preserving materials for paints, metal and rubber
(
p. 142)
– Treat all plastic parts and powder-coated parts with a mild
cleaning and care product.
Special cleaner for glossy and matte paint finishes, metal
and plastic surfaces ( p. 143)

STORAGE
19.1
Storage
Warning
Danger of poisoning Fuel is harmful to health.
- Avoid skin, eye and clothing contact with fuel.
- Immediately consult a doctor if you swallow fuel.
- Do not inhale fuel vapors.
- Rinse the affected area immediately with plenty of water in the event of contact with the skin.
- Rinse the eyes thoroughly with water, and consult a doctor in case of fuel contact with the eyes.
- Change your clothing if fuel spills on them.
- Keep fuels correctly in a suitable canister, and out of the reach of children.
Info
If you plan to garage the motorcycle for a longer period, perform the following steps or have them per-
formed.
Before storing the motorcycle, check all parts for function and wear. If service, repairs, or replacements
are necessary, you should do this during the storage period (less workshop overload). In this way, you
can avoid long workshop waiting times at the start of the new season.
-
When refueling for the last time before taking the motorcycle
out of service, add fuel additive.
Fuel additive ( p. 142)
-
Refuel. ( p. 32)
Tip
Fill the fuel tank completely as specified, using fuel
with the lowest possible ethanol content.

Guideline
Ideal charging and storage
10 … 20 °C (50 … 68 °F)
temperature of the lithium-
ion battery
-
Store the vehicle in a dry location that is not subject to large
fluctuations in temperature.
Info
Husqvarna Motorcycles recommends jacking up the
motorcycle.
-
Raise the motorcycle with a lift stand. ( p. 49)
–
Cover the vehicle with a tarp or a similar cover that is perme-
able to air.
124
STORAGE 19
Info
Do not use non-porous materials since they prevent
humidity from escaping, thus causing corrosion.
Avoid running the engine for a short time only. Since
the engine cannot warm up properly, the water vapor
produced during combustion condenses and causes
valves and the exhaust system to rust.
19.2
Putting into operation after storage
- Install the 12-V battery.
(
p. 102)
– Remove the motorcycle from the lift stand. ( p. 49)
- Perform checks and maintenance measures when preparing
for use. ( p. 26)
- Take a test ride.

SUBSTANCES
Brake fluid DOT 4 / DOT 5.1
Standard/classification
- DOT
Guideline
- Use only brake fluid that complies with the specified standard (see specifications on the container) and that
exhibits the corresponding properties.
Recommended supplier
Castrol
- REACT PERFORMANCE DOT 4
MOTOREX®
- Brake Fluid DOT 5.1
Coolant
Guideline
- Only use high-grade, silicate-free coolant with corrosion inhibitor additive for aluminum motors. Low grade
and unsuitable antifreeze causes corrosion, deposits and frothing.
- Do not use pure water as only coolant is able to meet the requirements needed in terms of corrosion pro-
tection and lubrication properties.
- Only use coolant that complies with the requirements stated (see specifications on the container) and that
has the relevant properties.
Antifreeze protection to at least
−25 °C (−13 °F)
The mixture ratio must be adjusted to the necessary antifreeze protection. Use distilled water if the coolant
needs to be diluted.
The use of premixed coolant is recommended.
Observe the coolant manufacturer specifications for antifreeze protection, dilution and miscibility (compatibility)
with other coolants.

Info
Do not use fuel containing methanol (e.g., M15, M85, M100) or more than 10% ethanol (e.g., E15,
E25, E85, E100).

STANDARDS
JASO T903 MA2
Different technical development directions required a separate specification for motorcycles - the
JASO T903 MA2 standard.
Earlier, engine oils from the automobile industry were used for motorcycles because there was no separate
motorcycle specification.
Whereas long service intervals are demanded for automobile engines, the focus for motorcycle engines is on
high performance at high engine speeds.
In most motorcycle engines, the transmission and clutch are lubricated with the same oil.
The JASO T903 MA2 standard meets these special requirements.
SAE
The SAE viscosity classes were defined by the Society of Automotive Engineers and are used for classifying
oils according to their viscosity. The viscosity describes only one property of oil and says nothing about quality.

28.1
Yellow and orange symbols
Yellow and orange symbols indicate an error condition that requires prompt intervention. Active driving aids are
also represented by yellow or orange symbols.
Malfunction indicator lamp lights up/flashes orange - The OBD has detected a malfunction
in the vehicle electronics. The malfunction indicator lamp also lights up if traction control is
activated and the speed limiter intervenes.
TC indicator lamp lights up orange - TC is enabled or is currently intervening. The TC indi-
cator lamp flashes if launch control is activated.
28.2
Green and blue symbols
Green and blue symbols reflect information.
QS indicator lamp lights up blue - The quickshifter is activated. The QS indicator lamp
flashes when the quickshifter is being programmed.
Indicator lamp B lights up green - ADVANCED mapping is activated.
