Lubrication * The lubrication grease is not filled before gearbox leave factory. Please fill in the suggested lubrication grease during assembly, the amount is roughly 70~90% of the gearbox inside cavity volume
* Lubricating grease is generally replaced in 2000 hours. When the grease is contaminated or is used in harsh environments, it is necessary to check the condition of aging and pollution and to change the time
* Reducer using lubricating oil: Molywhite RE-00 or VIGO-grease REO other similar grade precision reducer special grease
