Risk of environmental damage due to leaking consumables!
Always let consumables drain into suitable recept
acles. Wipe up any con-
sumables that escape.
Store/dispose of consumables and any soaked equipment properly.
Ask about the applicable regulations.

There is a risk of scalding when the cooling circuit is hot!
The hot cooling circuit is under pressure. When you open the expansion
tank, you could be scal
ded by escaping vapour/coolant.
Wear suitable protective gloves and cover the cap on the expansion tank
with a rag before op
ening it.
Turn the cap slowly to the first detent in order to allow the pressure to be
released
