COOLING
The water pump (1) housed in the engine induces forced circulation of
the coolant liquid.
There is no thermostat in the system, therefore, when the engine is cold,
it is important to moderate the number of revs. of the engine and speed.
Proceed for at least 5 minutes at half throttle and at reduced pace to
allow the engine to reach an adequate working temperature.
Cooling takes place thanks to the passage of air through the fins of the
radiator, the lower the speed, the less the cooling effect. Dirty radiator
fins also decrease the cooling effect.
The pressure caused by the high liquid temperature is adjusted by a
valve on the radiator cap (2); it is possible to reach temperatures of
120°C without problems.
- CHECK THE LEVEL OF THE COOLANT LIQUID WHEN THE ENGINE IS
COLD. IF YOU MUST REMOVE THE RADIATOR CAP WHEN THE ENGINE
IS HOT, COVER IT WITH A CLOTH AND OPEN SLOWLY TO RELEASE THE
PRESSURE. ATTENTION, BURNS HAZARD!
- DO NOT DISCONNECT THE RADIATOR HOSES WHEN THE ENGINE IS
HOT. THE COOLANT LIQUID AND THE HOT STEAM THAT ESCAPE, MAY
CAUSE SERIOUS BURNS.
- IF YOU ARE BURNED, PUT THE INTERESTED PART UNDER COLD RUN-
NING WATER.
- THE COOLANT IS TOXIC! THEREFORE PRESERVE IT OUT OF THE REACH
OF CHILDREN.
- IF YOU SWALLOW COOLANT, SEEK MEDICAL ADVICE IMMEDIATELY.
- IF THE COOLANT HITS THE EYES, RINSE IMMEDITAELY WITH COLD
WATER AND SEEK MEDICAL ADVICE.
The coolant liquid is a mixture of antifreeze at 40% and water at 60%.
The antifreeze protection limit must however be at least -25°C.
This mixture offers protection against freezing as well as a good protection
against corrosion and therefore should not be replaced by pure water.
WARNING
- AFTER THE COOLANT LIQUID HAS BEEN EMPTIED, WHEN RE-FILLING IT
IS NECESSARY TO BLEED THE COOLING SYSTEM (SEE NEXT PAGE).
- ALWAYS USE GOOD QUALITY PRODUCTS TO PREVENT CORROSION
OR FOAM.
- IN EXTREME WEATHER CONDITIONS OR IN STOP-AND-GO TRAFFIC,
OVERHEATING MAY OCCUR. TO SOLVE THIS PROBLEM, AN ELECTRIC
FAN KIT IS AVAILABLE FOR ALL MODELS WITH ELECTRIC STARTER (ASK
AT YOUR TM AUTHORIZED DEALER).
