1. Engine coolant temperature indicator
It indicates the engine coolant temperature, which should normal-
ly be approximately 80–85°C.
After starting the engine, let it warm up before starting work.
If the indicator exceeds the set values during operation and
reaches the red overheating area (B), let the engine idle until the
indicator returns within the normal operating range (A).
When the indicator reaches the red overheating area (B), the
acoustic alarm sounds and the warning light blinks (C).
If the inconvenience occurs again, try to find out if there is any
failure (see "3.7.6 OTHER TROUBLES").
