Checking the antifreeze and coolant level
Warning
Danger of scalding The coolant gets very hot when the motorcycle is driven and is under high pressure.
– Do not open the radiator, radiator hoses or other cooling system components when the engine is hot. Allow the engine and cool-
ing system to cool down. If you scald yourself, hold the affected area under cold water immediately.
Warning
Danger of poisoning Coolants are poisonous and a health hazard.
– Avoid contact between coolants and skin, eyes and clothing. If fuel gets into your eyes, rinse immediately with water and con-
tact a doctor. Wash affected skin areas immediately with soap and water. If coolant is swallowed, contact a doctor immediately.
Change clothes that have come into contact with coolants. Keep coolants out of the reach of children.
