Filling the Lubricant
This chapter describes the filling of lubricant.
Note: For the reduction gear already filled with lubricant, perform the procedure described in
this chapter only for replacing the lubricant.
Before filling the lubricant, take care regarding the following precautions.
• If the product is not filled with lubricant, fill it with an appropriate amount of
Nabtesco-recommended lubricant before use.
• 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, oil seals could fall off or lubricant could leak.
If overfilled, the temperature increases during operation and the internal pressure also increases. As
a result, oil seals could fall off or lubricant could leak.
If the lubricant is not filled sufficiently, it could lead to premature damage of 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.
