5.7 Lubrication
At the time of delivery, the gears are conserved with preservation oil. The characteristics of the lubricating grease and oil
types approved by Harmonic Drive® are not changed by mixing with the preservation oil. It is therefore not necessary to
remove the preservation oil completely from the gear components. However, the mating surfaces must be degreased before
the assembly.
