The purpose of this paper is to determine the damage to the runway on a lathe maximat V13 and to determine the treatment that is done on the basis of the V13 lathe maximat laboratory polytechnic civil engineering maintenance Semarang. The data collection method used to detect damage, repair, and maintenance of the runway on a lathe maximat V13 in laboratory maintenance engineering polytechnic semarang country is the primary data obtained through observation and interviews, while the secondary data obtained through literature. The results showed that the damage caused to the foundation lathe prior to setting it caused by: The changing position of the runway, the runway surface means are not, and corrosion occurs. After setting it on the runway V13 lathe maximat flatness foundation on a lathe is still within the limits of tolerance deviation. But the foundation repair method maximat V13 lathe in Mechanical Engineering Laboratory Care Semarang State Polytechnic kaena taught not take a long time and people who are experts in their field. This study also describes the foundation of care on a lathe maximat conducted periodically V13 is 1 daily maintenance: cleaning and lubricating foundation lathes, 2 monthly treatments: do inspections like checking and setting the foundation fasteners, 3 annual treatments: do scraped . Maintenance action is in accordance with the manual can be accounted.
