GENERAL INFORMATION
COOLANT
The coolant is composed of ethylene glycol that, under certain conditions, can become inflammable and send out
invisible flames causing severe burns.
DANGER
Be careful not to spill the coolant on the red-hot parts of the engine and the exhaust system: it may catch
fire and send out invisible flames.
In case any maintenance operation should be required, it is advisable to use latex gloves.
Even if toxic, coolant has a sweet flavour. Never leave it inside open containers or within the reach of
animals to prevent the risk of drinking.
KEEP AWAY FROM CHILDREN.
Do not remove the radiator plug when the engine is hot. The coolant is under pressure and could cause
severe burns.
HYDROGEN GAS AND BATTERY ELECTROLYTE
DANGER
The battery electrolyte is a toxic, caustic substance containing sulphuric acid and thus able to cause
severe burns in case of contact.
Always wear tight gloves and protective clothes when handling this fluid.
If the electrolyte gets in contact with the skin, carefully wash the parts of your body that get in contact
with the fluid with abundant fresh water.
Always use a protection for your eyes since also a very small amount of the battery fluid can cause
blindness. In the event of contact with your eyes, carefully wash them with water for fifteen minutes and
then consult immediately an eye specialist.
Should you accidentally drink some fluid, drink abundant water or milk, then drink magnesia milk or
vegetable oil and consult immediately a doctor. Battery releases explosive gases. Keep flames, sparks,
cigarettes and any other heat source away from the battery. Make sure the room is well-aerated when
servicing or recharging the battery.
KEEP AWAY FROM CHILDREN.
The battery fluid is corrosive
Do not pour it on the plastic parts.
Make sure that the electrolyte acid is suitable for the type of battery used.
GENERAL PRECAUTIONS AND INFORMATION
Follow these instructions closely when repairing, disassembling or reassembling the motorcycle or its components.
DANGER
Using bare flames is strictly forbidden when working on the motorcycle. Before servicing or inspecting
the motorcycle: stop the engine and remove the key from the ignition switch; allow for the engine and
exhaust system to cool down; where possible, lift the motorcycle using adequate equipment placed on
firm and level ground. Be careful of any parts of the engine or exhaust system which may still be hot to
the touch to avoid scalds or burns.
Never put any mechanical parts or other vehicle components in your mouth when you have both hands
busy. None of the motorcycle components is edible. Some components are harmful to the human body
or toxic.
Unless expressly specified otherwise, motorcycle assemblies are refitted or re-assembled by reversing
the removal or dismantling procedure. Where a procedure is cross-referred to relevant sections in the
manual, proceed sensibly to avoid disturbing any parts unless strictly necessary. Never attempt to polish
matte-finished surfaces with lapping compounds.
Never use fuel instead of solvent to clean the motorcycle.
Do not clean any rubber or plastic parts or the seat with alcohol, petrol or solvents. Clean with water and
neutral detergent.
Always disconnect the battery negative (–) lead before soldering any electrical components.
When two or more persons service the same motorcycle together, special care must be taken to avoid
personal injury.
BEFORE DISASSEMBLING ANY COMPONENTS
•
Clean off all dirt, mud, and dust and clear any foreign objects from the vehicle before disassembling any
components.
•
Use the model-specific special tools where specified.
