Coolant
Coolant replacement must always be carried out by authorised
personnel. See the engine instruction manual. Please note that
dierent types of coolant are used in the standard and eco models.
(See chapter 3.7 Oils and lters)
Open the cover of the expansion vessel (4). Fill to 3 cm from the
top edge. Close the cover. Please note that at the normal operating
temperature, if coolant is overlled, the liquid can leak out from
the drain hose (5). This is not hazardous for the machine. When
replacing the coolant (only authorised personnel permitted to do
this) on cab models, air bleeding of the heating package may be
required. This is done via aventing hose in the roof. See the picture
on page 19, item (13).

WARNING! Never open the expansion vessel when the engine is warm or when the engine is running – risk of high pressure.
The coolant in awarm machine can be extremely hot. Risk of injuries from burns.
