Lubricant replacement procedure
7.4.3.
This section describes how to replace lubricants.
The replacement procedure is different for the straight and pulley input type and the right angle input type.
Replace the lubricant correctly according to the following procedure.
• When handling the lubricant, be sure to wear protective goggles and rubber gloves.
When replacing the lubricant, turn OFF the power source (e.g., power supply) and execute
lock-out/tag-out so that the power will not be turned ON by accident. Otherwise, you could be caught
by the rotation section, which will result in injury.
If the lubricant gets in your eyes or touches your skin, it could cause inflammation.
When the safety cover near the reduction gear has been removed for replacement/maintenance of
lubricant, be sure to return them to their original positions after the procedure.
If the lubricant is overfilled, there is a possibility of high internal pressure and that an oil seal could fall
off, the lip could be reversed, or lubricant could leak. If the lubricant is insufficient, a lubrication failure
could occur and the reduction gear could be damaged.
If the lubricant is not filled sufficiently, it could lead to premature damage of the reduction gear.
