<![CDATA[Background Hydron extrude machines in line 4 have a high enough total downtime, until the October 2019 period with a total of 264, 33 hours. Damage that often occurs in extrude machines from each Extrude Hydron engine subsystem, namely vacuum filter, vacuum hose and digital vacuum indicator. Aim to focus on steps to reduce damage. And from maintenance ensures the level of reliability and readiness while minimizing maintenance costs. Method on the extrude hydron machine is to use visual inspection and quantitative presentation. Results and Discussion Damage that occurs in vacuum filter components that often need to be caused by dust contamination, Automatic sensors (Limit Switch Piston, Pneumatic Limit Switch Cylinderr) are contaminated with dust particles. In repairing the damage that occurs is based on field conditions, so that the repair downtime is quite long due to the availability of spare parts and technical personnel. Conclusion in minimizing damage to extrude hydron machines using preventive maintenance]]>
