■ Lubricating oil

・Be sure to use the specified lubricating oil.

・ Do not mix any other lubrication.

・ If you use this product in an area with an ambient temperature of 0ºC or less, or 40ºC or more, heat- or cold-resistant lubricating oil is required.

・ Since, unless otherwise requested, the speed drive is filled with the proper amount of lubricating oil before shipping, additional lubrication is not

required.

・ Check the oil level every day.

・ Keep the replacement interval, and replace accordingly.

・ At initial operation, confirm the rotating direction of the output shaft, and gradually apply the load.

・ The handle rotational direction and increasing or decreasing speed may depend on the handle mounting direction. For more information,

please contact us.

・ The surface temperature of the speed drive housing under normal operation can reach up to approximately 50ºC higher than the ambient

temperature.

・ Switch between forward and reverse rotation after the motor (input) shaft stops completely.

・ Never change the speed when operation stops.

・ Be careful not to overload.

・ NRX is an output torque limiting model. Especially in the middle- and high-speed areas, the speed drive may be overloaded even with

the motor rated current value or less. For more information, please contact us.

■ Dial Plate & Load

・ The output speed will not change as long as a load does not change.

If a load changes greatly, however, the output speed might change even

at the same dial plate position

・ Note that the output speed might change if a load changes greatly.

■ Output Speed

・

When using product continuously, use it in the middle and high-speed areas,

which secures high efficiency.

　　・ If a special request was not given at the time of order, the rotation speed is set

to 0 rpm when a light load is applied.

　　・ If you continuously use this unit in the low-speed area of 100 rpm(*1) or less,

it could be susceptible to load changes, and the rotation speed might become unstable.　

■ Input Speed

・Allowable input speed:　　　　　　　　　　　　　　　　　

based on the standard specifications.

When using the product with a lower input speed than the above, please contact us.

Operating Precautions

*We recommend using the automatic control when high accuracy is desired.

Precautions during operation

For purchase of the lubricating oil (special traction drive oil for the speed change section),

*Refer to “ 3 Special lubricating oil” described on page 8.

Lubricating oil plays an important role, which can be used not only for power transmission, but also for burn,
wear, rust prevention, and for cooling.
Since lubricating oil greatly influences the performance of the product and service life, be sure to use the
special lubricating oil only.
