Removing and remounting the battery *
The battery only needs to be removed if the motorcycle is being immobilized.
Remove the screws [1] on both sides, loosen the screws [2] 2 turns and remove
the front spoiler towards the front. Push the cables to the side. Remove the
screws [3] and fold the battery cover [4] down.
First disconnect the negative terminal, then the positive terminal from the
battery. Make sure the battery terminals are not bent when they are removed.
Remove the battery cover and take out the battery.
Charge the battery before and after storage. Storage temperature 0 - 35°C.
When remounting the battery, position it in the battery compartment and mount
the battery cover. First connect the cables on the positive terminal, then con-
nect the negative terminal to the battery to avoid a short-circuit. Open the
battery cover and fasten with 2 screws. Remount the front spoiler. Apply Loctite
243 to the screws [1] and tighten to 10 Nm.
– IF ELECTROLYTE (SULPHURIC ACID) LEAKS FROM THE BATTERY, PROCEED WITH
GREAT CARE. THE ELECTROLYTE CAN CAUSE SEVERE BURNS.
– IN THE CASE OF SKIN CONTACT RINSE THOROUGHLY WITH WATER.
– IN THE CASE OF CONTACT WITH THE EYES, THOROUGHLY RINSE EYES WITH
WATER FOR AT LEAST 15 MINUTES. IMMEDIATELY CONSULT A DOCTOR.
– THE BATTERY IS A CLOSED MODEL BUT CAN NEVERTHELESS EMIT EXPLO-
SIVE GASES. AVOID SPARKS AND OPEN FIRE NEAR THE BATTERY.
– DEFECTIVE BATTERIES MUST BE STORED OUT OF THE REACH OF CHILDREN.
ENSURE PROPER DISPOSAL OF DISCARDED BATTERIES.
– THE SCREWS ON THE UNDERRIDE PROTECTION MUST BE SECURED WITH LOC-
TITE 243 TO PREVENT THEM FROM BECOMING LOOSE.
NEVER DISCONNECT THE BATTERY WHILE THE ENGINE IS RUNNING. THIS WILL
DESTROY THE RECTIFIER-REGULATOR.
Charging the battery
Note: a battery charger, item no. 58429074000, is available from your KTM
dealer. You can also use the battery charger to test the off load voltage, starta-
bility of the battery and the generator capacity.
Remove the front spoiler and fold the battery cover down; then determine the
battery's charge condition. To determine the charge condition, use a voltmeter
to measure the voltage between the battery terminals (off load voltage). For
a precise measurement, the battery should not have been charged or discharged
for at least 30 minutes.
If the voltage exceeds 12.4 V, it does not need to be charged.
If the voltage is below 12.4 V, the battery should be charged.
CHARGING:
Disconnect the negative terminal from the battery to avoid damage to the motor-
cycle's electronic system.
Connect the battery charger to the battery terminals. First connect the cables
to the positive terminal, then to the negative terminal on the battery. Charge
the battery for 5 to a max. of 10 hours with 1.4 amperes and a max. of 14.4
volts. For a quick charge, do not charge the battery with 4.5 amperes and a
max. of 14.4 volts for more than 1 hour.
– ALWAYS DISCONNECT THE NEGATIVE TERMINAL FROM THE BATTERY PRIOR TO
CHARGING TO AVOID DAMAGE TO THE MOTORCYCLE'S ELECTRONIC SYSTEM.
– IF THE CHARGE CONDITION CANNOT BE ESTABLISHED, THE BATTERY MAY ONLY BE
CHARGED 5 TO A MAX. OF 10 HOURS WITH 1.4 AMPERES AND A MAX. OF 14.4 VOLTS.
– ALWAYS CONNECT THE BATTERY TO THE CHARGING UNIT BEFORE TURNING THE
CHARGING UNIT ON.
– WHEN RECHARGING THE BATTERY IN CLOSED ROOMS THERE IS SUFFICIENT
VENTILATION. EXPLOSIVE GASES ARE RELEASED DURING THE BATTERY CHARGING
PROCESS.
– CHARGING TIME AND CHARGING VOLTAGE SHOULD NOT EXCEED THE STATED VAL-
UES. OTHERWISE ELECTROLYTE WILL BE RELEASED THROUGH THE SAFETY VALVES.
– AVOID QUICK CHARGING IF POSSIBLE.
– TO AVOID DAMAGE, DO NOT REMOVE THE LOCKING BAR.
Jump start
Jump starts are not recommended since they can damage the motorcycle's
electronic system.
