2. Setting
2.1 Handling procedures
Use device as stipulated in specification.
●Never fail to calculate selection upon using device. Use device within load and number of rotation stipulated in
specification.
○If otherwise, it may invite malfunction or breakage.
●Do not use the product in the atmosphere of explosive gas or flammable gas, in the corrosive or splashy
atmosphere or near a combustible material.
○Otherwise, a fire, an electric shock or an injury may be caused.
●Do not attach the load over the allowable level.
○Otherwise, internal breakage may be caused.
●The keyway width of the standard type is of precision class. When fitting the key, be careful not to have an
impact on the shaft but grind the key so that it can force-fit in the keyway easily.
○Otherwise, the shaft or the motor may be broken.
○Key must be prerared by customer.
●This product has no self-lock function. To lock the load, provide an external locking mechanism or use
the motor built in with a brake. To lock the load with the motor-side brake, observe the instructions
prescribed in the manual of the motor.
○Otherwise, the load may drop.
Provide emergency stoppage circuit.
●Design with an emphasis placed on safety so that the power supply is instantaneously cut at the time of
emergency.
Don't install broken device.
●Don't install the device when it is broken.
○If otherwise, it may invite breakage or injury or secondary disaster.
Positively fix device.
●Upon setting device, fix it positively.
Mount device in accordance with requirements in manual and weight of device.
○If otherwise, device may fall during operation and mounting process resulting into secondary disaster.
●Make sure that bolt and screw are not loosely.
●When attaching a load, confirm no looseness in the key or the shaft and fasten the set bolt firmly.
○Otherwise, the load may drop unexpectedly.
●If the keyway is worn after long-time use or damaged under excessive torque, ratcheting (tripping) may
occur. If load drop or other serious danger is conceivable, take appropriate measures against load drop or
such danger.
○Otherwise, the load may come off during the operation, casing an injury or a secondary disaster.
Protect device.
●Rust-preventing surface treatment is not provided with output, input shaft and mounting surface in oder to keep
high precision. To those portions that requires rust-preventing treatment, apply rust-preventing oil or grease.
○Depending on atmosphere and storage conditions, rust may appear
●Make sure to protect device with cover depending on usage environment.
○If otherwise, it may cause malfunction or breakage.
●Our product is applied with an anticorrosive agent to the shaft portion for the temporary prevention of
corrosion. Before installing the product, remove the anticorrosive agent film.
◎Type of anticorrosive agent: Oil-based varnish
[How to remove the anticorrosive agent]
Wipe it off with a cloth soaked with alcohol for paint or white kerosene.
Don't forcibly turn device.
●Don't forcibly turn with device attached to machine at output shaft.
○If otherwise, it may cause breakage.
●Before connecting the product to the machine, check to confirm the direction of rotation.
○Otherwise, an injury or machine breakage may be caused.
●When using a coupling, select one that can accommodate eccentricity.
○Otherwise, noise, vibration or axis breakage may be caused.
Don't give impact or force on device.
●Don't give impact or the like. Be careful upon imposing load on device
○ If otherwise, it may cause breakage.
