· The lifting platform should be cleaned sufficiently during maintenance in order to quicker identify emerging damages of the paint and the components. Waste lubricants should also be disposed of immediately instead of reusing it, as the contained dirt could damage essential parts.
· The oil container should be cleaned at least once a year and be completely replaced in case of occurred damages.
· Although the lifting platform is often seen as a tool, any paint damage should be repaired immediately after its discovery in order to prevent appearing rust.
