Maintenance Technical Library (MTL) is an important structure in the maintenance department, it is the place that contains and stores all technical information. MTL is becoming gradually more virtual, with an Internet or Intranet based technical library maintenance technicians can have easy access to it. MTL makes it possible for technicians to have all the information (settings, diagrams, drawings) and make calculated decisions based on them. A brilliant idea for MTL is a display cabinet for broken parts, bearing and other small items. Ensure that there are backups of the CMMS and MTL files and assign someone to make sure everything is up-to-date.
