Risk of injury Battery acid and battery gases cause serious cauterization.
–Keep batteries out of the reach of children.
–Wear suitable protective clothing and goggles.
–Avoid contact with battery acid and battery gases.
–Keep the battery away from sparks or open fire. Charge only in well ventilated rooms.
–In the event of skin contact, rinse with large amounts of water. If battery acid gets in the eyes, rinse with water for at least
15 minutes and contact a doctor.
Warning
Environmental hazard Battery parts and acid are harmful to the environment.
–Do not discard batteries with the household trash. Dispose of a defective battery in an environmentally compatible manner.
Give the battery to your KTM dealer or to a recycling center that accepts used batteries.
Warning
Environmental hazard Hazardous substances cause environmental damage.
–Oil, grease, filters, fuel, cleaners, brake fluid, etc., should be disposed of as stipulated in applicable regulations.
Info
Even if there is no load on the battery, it loses power every day.
The charge state and the type of charge are very important for the service life of the battery.
Fast recharging with a high charge current shortens the battery's service life.
If the charge current, the charge voltage and the charge time are exceeded, electrolyte escapes through the breathing holes.
The battery capacity is then reduced.
If the battery is discharged from starting, it must be recharged immediately.
If it stands for a long time in a discharged state, the battery becomes over-discharged and sulfated, and then it is destroyed.
The battery is maintenance-free, i.e., the acid level does not have to be checked.
–Switch off all consumers and the engine.
–Remove the seat. ( p. 7)
–Disconnect the minus (negative) cable of the battery to avoid damage to the motor-
cycle's electronics.
400240-10

Battery charger (58429074000)
You can also use the battery charger to test the open-circuit voltage and cranking
power of the battery, and to test the generator. With this device, you cannot over-
charge the battery.
Info
Never remove the lid .
Charge the battery with at most 10% of the capacity specified on the bat-
tery .
–Switch off the charger after charging. Disconnect the battery.
Guideline
The charge current, charge voltage and charge time must not be exceeded.
Charge the battery regularly when the
motorcycle is not in use
3 months

Danger
Fire hazard Fuel is highly flammable.
–Never refuel the vehicle near open flames or burning cigarettes, and always switch off the engine first. Be careful that no
fuel is spilt, especially on hot vehicle components. Clean up spilt fuel immediately.
–Fuel in the fuel tank expands when warm and can escape if the tank is overfilled. See the notes on refueling.
Warning
Danger of poisoning Fuel is poisonous and a health hazard.
–Avoid contact of the fuel with skin, eyes and clothing. Do not inhale fuel vapors. If fuel gets into your eyes, rinse imme-
diately with water and contact a doctor. Wash affected skin areas immediately with soap and water. If fuel is swallowed,
contact a doctor immediately. Change clothing that has come into contact with fuel.
