Chapter 6 Filling the Lubricant 

53 

Chapter 6 Filling the Lubricant 

This chapter describes the filling of lubricant. 

Before filling the lubricant, take care regarding the following precautions. 

This product is not filled with lubricant when shipped from Nabtesco. Before operating the product, 
be sure to fill it with an appropriate amount of lubricant specified by Nabtesco. 

When pneumatic pressure is used for filling the lubricant, set the pressure below 0.03 MPa.

Be sure to leave a space about 10% of the total volume to be filled with the lubricant.

 

If the internal pressure of the reduction gear increases, an oil seal could fall off or lubricant could 
leak. 

 

If overfilled, the temperature increases during operation and the internal pressure also increases. As 
a result, an oil seal could fall off or lubricant could leak. 

 

If the filling amount of the lubricant is insufficient, it could cause premature damage to the reduction 
gear. 

6.1.   Precautions when handling the lubricant 

This section describes the precautions when handling lubricants. 

 

Before handling the lubricant, read the precautions described on the container of the lubricant and 
use it correctly. Improper use could impair your health. 

 

Wear protective goggles to protect your eyes from the lubricant. If it gets into your eyes, it could 
cause inflammation. 

 

Wear rubber gloves to protect your skin from the lubricant. If it touches your skin, it could cause 
inflammation. 

 

Do not eat or put the lubricant into your mouth. If it gets into your mouth, it could cause diarrhea or 
vomiting. 

 

If anything is unclear, refer to the Safety Data Sheet. If it is not available, contact our service 
representative.
