Fuse
The fuse [1] is located in the starter relay of the E-starter [2] underneath the
left side paneling.
Having removed the left side paneling, the air box cover and the protection
cover [A], you will be able to see the fuse.
The following loads are connected to it:
– E-starter system
– horn
– flasher lights
– electronic speedometer
The starter relay also contains a (10 amp) spare fuse [3].
Replace a blown fuse only with an equivalent one. If a new fuse that has just
been installed gets blown again, you are strongly advised to have it
inspected by a KTM dealer.
The fuse capacity is 10 Ampere.
Under no circumstances is a stronger fuse allowed to be installed or a fuse
allowed to be “repaired”. An improper treatment could damage the whole elec-
trical installation.
Cooling system
The water pump [1] in the engine circulates the cooling liquid. The cooling
liquid is cooled by the air stream. This means that the cooling effect decreases
with the traveling speed. Dirty radiators additionally reduce the cooling effect.
Pressure induced by heating of the coolant in the system is controlled by a
valve in the radiator cap [2]; a water temperature rising up to 120° C
(248° F) is admissible, without fear of problems.
Some models are equipped with a thermostat so that the engine reaches its
operating temperature more quickly. When the engine is cold, the liquid
coolant circulates in the cylinder and the cylinder head. As soon as the
cooling liquid has reached a temperature of approximately 55°C, the thermo-
stat opens and the cooling liquid is also pumped through the two aluminum
radiators.
– If possible, always check level of cooling liquid when engine is cold. If
you have to open the radiator cap [2] when the engine is hot, use a rag to
cover the cap and open slowly to release pressure.
Caution - scalding hazard.
– Do not detach any radiator hoses while the engine is hot. The escaping
hot coolant and the steam may cause serious burns.
– In case you get burnt, hold the affected part of your body under running
cold water right away.
– Coolant is toxic. Keep the coolant out of the reach of children.
– In case coolant is ingested, consult a doctor immediately.
– If coolant gets into your eyes, rinse them out with water immediately and
go see a doctor.
Use a mixture of 50% antifreeze and 50% distilled water for the cooling
liquid. The antifreeze should be designed for temperatures of at least -25°C.
This mixture offers frost protection as well as good corrosion protection and
should not be replaced by water alone.
For the cooling system, use only with high-grade antifreeze (e.g. Motorex Anti-
Freeze). Using lower-grade antifreeze agents can cause corrosion and coolant
foaming.
