General safety rules
Carbon monoxide
When a maintenance operation must be performed with the engine running, make sure that the working
area is well-ventilated. Never run the engine indoors.
Warning
Exhaust gases contain carbon monoxide, which is a poisonous gas that can cause unconsciousness or even
death if inhaled.
Run the engine outdoors or, if working indoors, use an exhaust gas extraction system.
Fuel
Always make sure the working area is well ventilated. Keep any sources of ignition, such as cigarettes, open
flames or sparks, well away from working area and fuel storage area.
Warning
Fuel is highly flammable and can explode under certain conditions. Keep away from children.
Hot parts
Warning
The engine and exhaust parts become hot when the motorcycle engine is running and will stay hot for some
time after the engine has been stopped. Wear heat-resistant gloves before handling these components or
allow the engine and exhaust system to cool down before proceeding.
Warning
The exhaust system might be hot, even after engine is switched OFF; pay particular attention not to touch
exhaust system with any body part and do not park the motorcycle next to inflammable material (wood,
leaves etc.).
Used engine oil
Warning
Prolonged or repeated contact with used engine oil may cause skin cancer. If working with engine oil on a
daily basis, we recommend washing your hands thoroughly with soap immediately afterwards. Keep away
from children.
Brake dust
Never clean the brake assembly using compressed air or a dry brush.
Brake fluid
Warning
Spilling brake fluid onto plastic, rubber or painted parts of the motorcycle may cause damages. Protect
these parts with a clean shop cloth before proceeding to service the system. Keep away from children.
Coolant
Engine coolant contains ethylene glycol, which may ignite under particular conditions, producing invisible
flames. Although the flames from burning ethylene glycol are not visible, they are still capable of causing
severe burns.
Warning
Take care not to spill engine coolant on the exhaust system or engine parts. These parts may be hot and
ignite the coolant, which will subsequently burn with invisible flames. Coolant (ethylene glycol) is irritant
and poisonous when ingested. Keep away from children. Never remove the radiator cap when the engine is
hot. The coolant is under pressure and will cause severe burns.
