MDM Engine Protection

The CR 6, CR 7, CR 8 and CR 9 soil compactors with MDM engine protection and COMPATROL^® 2.0 offer extensive safety precautions. In case of low engine oil pressure, high engine temperature or heavily soiled air filter, the Hatz diesel engine switches off automatically. If an error occurs, the operator is made aware of this by an LED indicator. Engine damages caused by inadequate maintenance are a thing of the past.

Life time and operational reliability of the engine are significantly extended.

The green LED signal indicates that the soil compactor is ready for use.
