Check lubricant quality
You can judge whether the lubricant needs to be replaced by checking for the following
features:
• Change in consistency
• Discoloration
• Degree of soiling
Replacing or Refilling Lubricant
• Fill the bearings uniformly with grease until all operating surfaces are well greased.
• For the rotor bearings, a lubricant quantity of one third to a maximum of half of the
bearing volume per bearing is required. If too much grease is used, the lubricant will
become unusable due to excessive temperature.
• Only one type of grease may be used, mixing different types of grease is prohibited.
The bearings have been filled at the factory with lithium base saponification roller
bearing grease F3.
• Refer to the “List of Lubricants” in this section for recommended bearing grease.
