●

Oil cooler

Scale removal

Remove the oil cooler water chamber cover. Flush
with scale remover and use a brass wire brush to
remove the scale from the inner surfaces of the oil
cooler tube nest.

●

Intercooler/Aftercooler

If scale build up occurs often, contact the local
HITACHI distributor/master dealer or representative
office for scale removal.
