Conducting daily maintenance requires only that the operators use measuring tools and their senses. Check the following.

• ・Noise ...Make sure that noise is not louder than usual and that there are no periodic abnormal sounds.
• ・Vibration ...Make sure there is no abnormal vibration
• ・Temperature ...Is the surface temperature of the reducer higher than normal?

A contact-type oil seal is used to seal the shaft of the speed reducer housing.

In most cases, there is no need to change the oil seals. However, you can increase the service life of the reducer by changing the oil seals after—as a guideline—10,000 hours of use.

Because the life of the oil seal depends on usage conditions, there may be cases where the oil seal needs to be replaced before 10,000 hours of operation.

Also, when using the product with food processing machines, especially those devices with which oil must not be used, install an oil pan or other damage prevention equipment to prepare for the rare occurrences of oil spills caused by issues such as malfunctions and the oil seals reaching the end of their service lives.

※In rare cases, grease discharges from the oil seal lip at the beginning of startup. This is only excess grease from filling during the assembly process; it does not indicate a function failure of the reducer.
