CHECKING THE COOLANT LEVEL

Carry out this check with the machine parked on a level
q
surface and the equipment resting on the ground.
Do not remove the radiator cap; the coolant level must
q
be checked with cold engine and by means of the com-
pensation tank.
The coolant tank (1) can be reached by raising the engine ho-
od (see "3.5.1 ENGINE HOOD") and opening the rear panel
(see "3.5.2 REAR PANEL") and the level must be included
between the MIN. and MAX. marks.
If necessary, add water or coolant and, if a constant and consi-
derable decrease in the fluid level can be noticed, check the ti-
ghtness of the radiator-engine unit and of the radiator casing.
