The greasing intervals depend on the use conditions. In normal use, a running distance of every 100 km or once every six months is a guideline for the replenishment of grease. Apply 0.5 to 2.0 gram of grease of the same type (lithium soap grease No.2) to the rail raceways. In this case, check regularly to see if there are oil films or if the grease is deteriorated. If the grease is discolored early or a large amount of powder from abrasion is generated, a re-evaluation of greasing intervals is recommended.
