Installation

When a suspension tool is provided for a motor, carry the motor using the suspension tool.
 When a motor is used for a lift, install a safety device on the machine side. There is a risk that a lifted cargo, etc. may fall off.
 If any oil component, grease, etc. may leak out in case of a fault and adversely affect the environment adversely, prepare
an oil pan (oil catcher) or other device to prevent leakage of oil or grease.

Provide a safety cover for components such as belts, chains, or gears.
 If small pieces of foreign matter enters through or water causes rust at the oil seal section of the output shaft, grease may
leak out. Take necessary precautions. Do not use the motor in a place that may be wet with water.
Operation

The motor shaft may move at start.
 Do not use the motor in an application in which an excessive impact torque is generated during stopping (example: stop-on
contact at high speed). Doing so may damage the motor.
 Always stop the operation and inspect the motor when any abnormal noise or vibration is generated during operation, or
when the specified characteristics cannot be achieved.
 In the case of variable load, a sound generated by the effect of end play of the motor shaft may be heard, but it will not
cause any performance problem.
Brake

When using a motor with a brake, always adopt the separate braking method or the direct current (quick) braking method
for the brake wiring connection.
 Do not operate a manual releasing mechanism of the brake while an object is suspended. There is a risk that a lifted cargo,
etc. may fall off.

Before starting operation of a geared motor with a one-touch manual releasing brake, always fix the releasing lever on the
lever receiver.
 For a lift application, adopt the direct current (quick) braking method for the circuit.
 In the initial use condition, the specified brake torque may not be achieved for the reason of the friction surfaces. In such a
case, repeat turning ON/OFF of the brake with a lightest possible load as a running-in process for the friction surfaces.
 A lining rubbing sound may be generated because of the brake structure, but it will not affect performance.
 For the connection with the separate braking method, it is necessary to match the operation timings between the motor and
the brake. If the operation timings are different, there is a risk of falling, crashing, or brake damage.
For the production date of the drive unit, check the serial number printed on the rating plate or on package. For how to find the
SERIAL, refer to
