Upon delivery and receipt of the reducer check the following. If a nonconformity or problem is
found, contact our nearest agent, distributor, or sales office.
(1) Do the items on the rating plate conform to what you ordered?
(2) Was there any part broken during transport?
(3) Are all bolts and nuts tightened firmly?
1—1) How to Refer to the Rating Plate
1—2) Lubrication Method
Since all MC drive IB series adopt grease lubrication, grease has been loaded on shipping
from factory. Put units into operation as they are.

When storing reducers for any extended period of time, consider the following important points.
2—1) Storage Location
Store the unit in a clean, dry place indoors.
• Avoid storage outdoors or in places with humidity, dust, sudden temperature change, or
corrosive gas.
DANGER
●Do not stand directly under a unit suspended by a crane or other lifting mechanism;
otherwise, injury or death may result.
3. Transport
CAUTION
●Exercise ample care so as not to drop the reducer. When a hanging bolt or hole is
provided, be sure to use it. After mounting reducer unit to the equipment, do not hoist the
entire machine using the hanging bolt or hole; otherwise, personal injury or damage to the
equipment and/or lifting device may result.
●Before hoisting, refer to the rating plate, crate, outline drawing, catalog, etc. for the weight
of the reducer. Never hoist a unit that exceeds the rating 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.
2. Storage
2—2) Storage Period
(1) Storage period should be less than 1 year.
(2) Export models need export rust prevention. Contact the tactory for details.
2—3) Use After Storage
(1) Oil seals will deteriorate when exposed to high temperatures and UV rays. Inspect the oil
seals before operation.
Replace the oil seals after long-term storage if there is any sign of deterioration.
(2) After starting the reducer, Verify that there is no abnormal sound, vibration, or heat rise. If
supplied as a brakemotor, check that the brake operates properly. If any anomaly is
observed, contact our nearest agent, distributor, or sales office.

4. Installation
CAUTION
●Do not use the reducer for purpose other than those shown on the rating plate or in the
manufacturing specification; otherwise, electric shock, injury, or damage to the equipment
may result.
●Do not place any object that will hinder ventilation around the reducer; otherwise, the
cooling effect is reduced, possibly leading to fire or burns due to excessive heat built-up.
●Do not step on or hang from the reducer; otherwise, injury may result.
●Do not touch the shaft end of the reducer, inside keyways, or the edge of the motor cooling
fan with bare hands; otherwise, injury may result.
●When the unit is used in food processing applications vulnerable to oil contamination,
install an oil pan or other such device to cope with oil leakage due to failure or limited
service life; otherwise, oil leakage may damage products.
4—1) Place of Installation
Ambient temperature: 0—40˚C
There is possibility of malfunctioning startup depending on rotational speed and torque of the
motor. When you use the motor at 0°C, please consult us.
Ambient humidity: 90% max. No condensation
Altitude: 1000m max.
Ambient atmospherethere should be no corrosive gas, explosive gas, or steam. The place
should be well ventilated without dust.
Location of installation: Indoors, with minimum dust and no water splashing.
• Units made to special specifications are necessary for installation under conditions other
than the above.
• Units made according to the outdoor, explosion-proof, or other specifications can be used
under the specified conditions without any problem.
• Install the units where inspection, maintenance, and other such operations can be carried
out easily.
• Install the unit on a sufficiently rigid base.

5. Coupling with Other Machines
CAUTION
●Confirm the direction of rotation before coupling the unit with the driven machine.
Difference in the direction of rotation may cause injury or damage to the equipment.
●When operating the reducer alone (uncoupled), remove the key that is temporarily
attached to the output shaft; otherwise, injury may result.
●Cover the rotating parts; otherwise, injury may result.
●When coupling the reducer with load, check that the centering, the belt tension and
parallelism of the pulleys are within the specified limits. When the unit is directly coupled
with another machine, check that the direct coupling accuracy is within the specified limits.
When a belt is used for coupling the unit with another machine, check the belt tension.
Correctly tighten bolts on the pulley and coupling before operation; otherwise, injury may
result because of misalignment.
(1) The standard output shaft of reducer is straight type. Recommend to use some kinds of
coupling which are not generated backlash at the coupling part.
(2) In case radial load is put on output shaft, do not exceed the value in the attached table,
"Standard model table".
(3) When output shaft is installed in coupling, do not force into it so that bearing may be
damaged.
5—1) Coupling Installation
• When installing a coupling, do not impact or apply excessive thrust load to the shaft;
otherwise, the bearing may be damaged or collar may be left.
• Thermal shrinking is the recommended installation method.
• When chain sprockets, gears or pullers are coupled with the reducer, please use within
the range of the allowable radial axial load, or shaft and bearing may be damaged.
(1) When Using a Coupling
The accuracy of the dimensions (A, B and X) shown in Fig.2 should be within the tolerance
shown in Table 1.

6. Operation
DANGER
●Do not approach or touch rotating parts (output shaft, etc.) during operation; otherwise,
loose clothing caught in these rotating parts may result in serious injury.
CAUTION
●Do not put fingers or foreign object into the opening of the reducer; otherwise, injury or
damage to the equipment may result.
●The reducer will become very hot during operation. Do not touch or come in contact with
the unit; otherwise, burns may result.
●If anomaly occurs during operation, stop operation immediately; otherwise, injury may
result.
●Do not operate the unit in excess of the rating; otherwise, injury or damage to the
equipment may result.
8
(2) When Using a Chain Sprocket and Gear
• The chain tension angle should be perpendicular to the shaft.
• Refer to the chain catalog for the chain tension.
• Select sprockets and gears whose pitch diameter are three times the shaft diameter or
geater.
•Install sprocket and gears so that their point of load application will be closer to the
recucer side with respect to the length of the shaft. (Fig.3)
(3) When Using a V-belt
• Excessive V-belt tension will damage the shaft and bearing. Refer to the V-belt catalog
for proper tension.
• The parallelism and eccentricity (ß) between two pulleys should be within 20'. (Fig.4)
• Use a matchend set with the same circumferential length when more than one belt is to
be installed.

7. Daily Inspection and Maintenance
DANGER
●Do not approach or touch any rotating parts (output shaft, etc.) during maintenance or
inspection of the unit; otherwise, loose clothing caught in these rotating parts may result in
injury or death.
CAUTION
●Do not put fingers or foreign objects into the opening of the reducer; otherwise, injury or
damage to the equipment may result.
●The reducer will become very hot during operation. Do not touch the unit with bare hands;
otherwise, burns may result.
●Identify and provide appropriate corrective action in a timely fashion and according to this
maintenance manual if any abnormal operating characteristics are observed. Do not
operate the unit corrective action has been taken.
●Do not use damaged reducers; otherwise, injury or damage to the equipment may result.
●We can not assume any responsibility for damage or injury as a result of an unauthorized
modification by a customer.
●Dispose of the reducer as general industrial waste.
7—1) Daily Inspection
To ensure proper and continued optimum operation, use table1 to perform daily inspections.
Table 2 Daily Inspection
Inspection item Details of inspection
Noise Is there abnormal sound? Is there sudden change in sound?
Vibration Is there vibration abnormally large? Does vibration change suddenly?
Foundation bolt
Grease leakage
Are foundation bolts loose?
Does grease leak from the gear section?
Surface temperature Is the surface temperature abnormally high? Does the surface temperature
rise suddenly?
When some anomaly is found during the daily inspection, contact our nearest agent, distributor, or sales
office.
