operation, maintenance, inspection, etc.). Thoroughly understand the machine, information about
safety, and all precautions for correct operation.
Maintain this manual for future reference.
- Pay particular attention to the "DANGER" and "CAUTION" warnings regarding safety and proper use.
Improper handling may result in physical damage, serious personal injury
and/or death.
Improper handling may result in physical damage and/or personal injury.
Matters described in may lead to serious danger depending on the situation.
Be sure to observe important matters described herein.
DANGER
- Transport, installation, plumbing, wiring, operation, maintenance and inspections should be
handled by properly trained technicians; otherwise, electric shock, injury, re, or damage to
the equipment may result.
- In the case of maintenance with disassembly, please contact the nearest authorized
maintenance shop.
- When the unit is to be used in a system for human transport, a protecting device for human
safety should be installed to prevent accidents resulting in personal injury, death, or damage
to the equipment due to running out of control or falling.

2. Storage
If this product is not for immediate use, note the following points when storing it.
2-1 Storage Location
Store the unit indoors in a clean and dry location.
Do not store the product outdoors. Store it in a location that is free of moisture, dust, extreme
temperature changes, corrosive gases, etc.
2-2 Storage Time
- Storage period should be less than 1 year.
- Standard rust prevention specications
External rust prevention Rust prevention oil is applied when shipping from the factory. Check the
rust conditions to see if any rust is forming on the machined surface every
six months after shipment. Reapply the rust prevention oil or any other rust
prevention process if necessary.
Internal rust preventionStore the product in a general factory or warehouse in an environment free
of moisture, dust, extreme temperature changes, corrosive gases, etc.
- If the product is for export, or if the storage time is longer than 1 year, adherence to special rust
prevention specications is required. Please consult with us.
- If the storage time is longer than 1 year, run the product for a few minutes under no load once every 2 to
3 months.
2-3 Using after Storage
- Oil seals are affected by temperature, ultraviolet light and other ambient conditions and can easily
degrade. After long storage periods, inspect it before operation, and replace any degraded seals with
new seals.
- 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 is
found, immediately contact the nearest authorized maintenance shop.

3. Transport
DANGER
- Do not step under a unit suspended by a crane or other lifting mechanism for transport;
otherwise, injury or death may result.
CAUTION
- When hanging bolts or holes are provided, be sure to use them. After mounting the unit to
a machine, do not hoist the entire machine by using the hanging bolts or holes; otherwise,
personal injury or damage to the equipment and/or lifting device may result due to falling of
the machine or failure of hanging metal tting.
- In the case the product is lifted by using the tapped hole on it, refer to the nameplate,
crate, outline drawing, catalog, etc. for the weight of the unit before hoisting. Never hoist
a unit that exceeds the load capacity of the crane or other mechanism being used to lift it;
otherwise, personal injury or damage to the equipment and/or lifting device may result.
- When the product is lifted, use suitable lifting parts, and conrm that eye bolts and nuts are
not loose.

4. Installation
CAUTION
- Do not use the unit for a purpose other than that indicated on the nameplate or in the
manufacturing specications; otherwise, injury or damage to the equipment may result.
- Do not place any object that will hinder ventilation around the reducer. Insufficient
ventilation can cause excessive heat that may result in burns or re.
- Do not step on or hang from the gearmotor or reducer; otherwise injury may result.
- Do not touch the shaft end of the product and inside key ways with bare hands; otherwise,
injury may result.
- Install a loss prevention device such as oil pan to machines particularly vulnerable to oil
especially (machine for food processing, machine for clean room, and so on) in case oil or
grease leaks; otherwise, oil or grease leakage may cause failure of the unit.

5. Mounting the Servo Motor
5-1 P1, PK1, P2, P Type
The product has a special shaft coupling between the reducer and the motor so that shaft with keyway
or D shaft other than straight shaft can be accommodated.
Attaching the motor in the following steps from (1) to (8): (In the case of a shaft with keyway, remove
the key before assembly).
(1) Wipe rustproong or other oils from the motor shaft surface and the ange surface of the reducer. (see
gure5-1).
(2) Place the reducer on an appropriate working table with the coupling [3] facing straight up.
(3) Remove the plug [1] from the setting hole.
(4) Manually align the components so that the coupling tightening bolt [2] can be tightened from the
setting hole [1].
(5) Insert the motor shaft into the center hole of the coupling [3]. Press the shaft straight into the
coupling, and engage the joint between the motor and the adapter plate [4].
In the case of the motor with the ange plate, set the ange plate [5] between motor and adapter
plate [4].
After tting the spigot of the ange plate [5] and adapter plate [4], insert motor shaft into the center
hole of the coupling [3], press in vertically and t the spigot of the motor and the ange plate [5].
(6) Lock the motor and the adapter plate [4] together by tightening the motor mounting bolt.
(7) Tighten the coupling tightening bolt [2] from the setting hole using a torque wrench. Tighten to the
appropriate torque value shown on Table 5-1 and 5-2.
(8) Reinstall the plug [1] from the setting hole.
