This thesis was commissioned by SCA Hygiene Products’ Nokia mill. The aim was to improve runnability and reduce downtime in packaging machines of converting line 1 of the Nokia mill by putting CIL into operation. Theories of CIL (Cleaning, Inspection and Lubrication) and RCA (Root Cause Analy-sis) are explained in the theory part if this bachelor’s thesis. CIL is basic element towards autonomous maintenance. Before CIL implementation operators and maintenance team work independently. With the use of CIL operators will have more detailed knowledge of their working place. And with that knowledge operators could maintain their working place completely in the future. CIL implementation was success, although there was no time to go through the whole CIL process cycle. The CIL process is not top priority at the Nokia mill, so the repara-tions from the defect list will take some time. In the future there will be more CIL implementations in the converting line 1 and in the other parts of the Nokia mill. There is no doubt that CIL would not improve the profitability of the converting lines and in the whole mill.
