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 scalded by escaping steam/coolant.
Wear suitable protective gloves and cover the cap on the expansion tank
with a rag before opening it.
Turn the cap slowly to the first detent in order to allow the pressure to be
released.

Risk of damage to engine due to lack of coolant.
If the coolant has to be topped up frequently, the cooling system may be
leaking. Have the cooling system checked by
Manitowoc Crane Care
or an
authorised GROVE dealer or your repair crew.
