Lubrication
The gears are originally lubricated and require no maintenance. The exception
is when the gears have been removed and the grease has been removed.
Bearings
The machine's bearings are originally lubricated and do not require regular
lubrication. If the bearings have been de-greased on purpose, they should be
lubricated with lithium grease.
