Do not store the unit outdoors or in locations where there is excessive moisture, dust, severe
temperature change, corrosive gas, etc.

2-2 Storage Period• Storage period should be less than 1 year.
• Standard Rust Prevention Specifications
  External rust prevention Standard specification is no coating. The unit is packaged with volatilerustproof paper, however, the surface condition should be checked forrust on the machined surfaces 6 months after shipment. When long-term
storage is necessary, rust prevention such as application of rust prevention
oil should be performed.
  Internal rust prevention The unit should generally be stored inside a factory or warehouse in anenvironment that is free from moisture, dust, severe temperature change,
corrosive gas, etc.
• When the unit will be shipped overseas or stored for a period of longer than 1 year, please contact us for
special rust prevention specifications.
• When the unit will be stored for a period of longer than 1 year, the unit should be operated for a few
minutes under no-load conditions every two or three months.

2-3 Use After Storage• T he oil seal is prone to deterioration due to the surrounding conditions such as temperature,
ultraviolet rays, etc., so after long-term storage, the unit should be inspected before operation, and any
deteriorated parts should be replaced with new parts.
• When the storage period is 2 years or longer, the oil seals and grease should be replaced before starting
operation.
• At the start of operation, make sure there is no abnormal noise, vibration, heat, etc. If any abnormality isfound, immediately contact the nearest agent, dealer or our sales office.

【5】Lubrication
DANGER● F or models that have not been lubricated with grease, be sure to lubricate with therecommended grease before operation. Operating the unit without lubricating with theproper grease could result in failure of the equipment caused by damage to the internal
parts of the reducer, and locking of the reducer.
● Be sure to use the recommended lubricating grease. If grease other than the recommended
grease is used, not only will the performance and life of unit be greatly decreased, but
failure of the equipment could occur due to damage to the internal parts of the reducer, andlocking of the reducer.

CAUTION● F urther adding grease to models that have already be greased may cause heat generation or
grease leakage to occur.
● Excessive grease filling causes rise in the internal pressure, which causes heat generation,
grease leak and oil seal detachment.
Insufficient grease will cause improper lubrication, resulting in damage to the parts.
● Dispose of the reducer as general industrial waste.

5-1 Grease• Depending on the specifications for use, the actual grease used may differ from the listed grease, so be
sure to check the delivery specifications.
• As a guide, change the grease and perform maintenance with disassembly of the equipment after every
20,000 hours of operation or every 3 to 5 years. In the case of maintenance with disassembly, pleasecontact the nearest agent, dealer or sales office.

• If any abnormality is found during daily inspection, contact the nearest agent, dealer or sales office.

8-2 Maintenance of Main Unit
• Oil seals have a life, and after long-term use there may be a decrease in the seal effect due to natural
deterioration and wear. Although the seal life greatly differs depending on the operating conditions andsurrounding environment of the reducer, it is recommended that the seal be replaced every 1 to 3 years.
If the sliding surface of the oil seal becomes worn or rusted, replace the seal with a new one.
The sliding surface is made of a carbon steel, so rusting may occur and advance due to moisture, etc.,
which may lead to damage of the oil seal, so periodically take rust prevention measures.
• Maintenance such as replacing oil seals and grease, disassembly inspection and repairs should never be
attempted by the customer, but should always be performed by a skilled worker of this company who
has special tools and expertise.In the case of maintenance with disassembly, please contact the nearest
agent, dealer or sales office.
