Coolant replacement

The coolant has to be replaced every
1000 operating hours or at least once
every two years.
N.B. Replacing the coolant may also be
necessary as part of the winter storage
procedure; in case that the coolant pre-
sent in the cooling system offers insuf-
ficient protection for the winter.
Be aware of the risk of skin
burning during draining the
hot coolant! Used coolant
must be collected in a con-
tainer for proper disposal
according to laws and regulations.
