6.3. Lubricant filling procedure
This section describes how to fill the lubricant.
If the product is not filled with lubricant, perform steps 1 to 7 by taking care regarding the following
precautions.
• When handling the lubricant, be sure to wear protective goggles and rubber gloves.
If the lubricant gets in your eyes or touches your skin, it could cause inflammation.
Step 1
• Remove both of the plugs for tapped holes for injecting/draining grease, and attach a grease nipple,
etc., and then attach the injector. (Reference: Fig. 6-3.)
If the injector is attached with the supply side down, air is less likely to accumulate in the reduction
gear, which facilitates the lubricant filling procedure.
Step 2
• Fill the specified lubricant using the injector.
• When filling the lubricant, be sure to remove the plug for tapped hole for injecting/draining grease
on the drain side.
• When pneumatic pressure is used for filling the lubricant, set the pressure below 0.03 MPa.
If you fail to remove the plug for tapped hole for injecting/draining grease on the drain side, the
internal pressure increases. As a result, oil seals could fall off or the oil seal lip could be reversed.
If the internal pressure of the reduction gear increases, oil seals could fall off or lubricant could leak.
The shape of the reduction gear may differ from the illustration in Fig. 6-3, depending on the ordered
specifications. For details on the shape, refer to the separately provided “Outer dimensions”
drawings and specification sheet.
Step 3
• If the lubricant overflows from the tapped hole for injecting/draining grease on the drain side
during filling, temporarily stop the filling.
Step 4
• Remove the injector from the grease nipple and plug the tapped holes for injecting/draining grease
on both the greasing and drain sides.
