CAUTION
• Unpack the unit after verifying that it is positioned right side up;
otherwise, injury may result.
• Verify that the unit received is in fact the unit ordered. When a
dierent unit is installed, injury or damage to the equipment may
result.
• Do not remove the nameplate.
Upon delivery and receipt of the reducer check the following. If
a nonconformity or problem is found, contact our nearest agent,
distributor, or sales oce.
[1] Do the items on the nameplate conform to what was ordered?
[2] Were there any parts that were broken during transport?
[3] Are all bolts and nuts tightened rmly?
1-1 How to Refer to the Nameplate
When making an inquiry, advise us of the [1] Nomenclature and [2]
Serial No.
1-2 Lubrication Method
IB Series PE Type is a grease-lubricated unit. Grease is injected into
the unit components before shipment so that no further lubrica-
tion is necessary during use.

When storing reducers for any extended period of time, consider
the following important points.
2-1 Storage Location
Store the unit indoors in a clean dry location.
Do NOT store the unit outdoors or in locations where there is
excessive moisture, dust, severe temperature change, corrosive
gas, etc.
2-2 Storage Period
• Storage period should be less than 1 year.
• Standard Rust Prevention Specications
External rust proong
Rustproofing oil is applied to the unit before shipment.
After the unit is delivered, check the machined faces for
rusting once every six months and reapply rustproong or
take other appropriate rust prevention steps as required.
Internal rustproong
The product should be used in an environment free of
severe moisture or dust, extreme temperature changes
and corrosive gases. Storage should be provided under
generally acceptable indoor manufacturing condition or
in a warehouse.
• When the unit will be shipped overseas or stored for a period of
longer than 1 year, please contact us for special rust prevention
specications.
• When the unit will be stored for a period of longer than 1 year, the
unit should be operated for a few minutes under no-load condi-
tions every two or three months.
2-3 Use After Storage
• The oil seal is prone to deterioration due to the surrounding condi-
tions such as temperature, ultraviolet rays, etc., so after long-term
storage, the unit should be inspected before operation, and any
deteriorated parts should be replaced with new parts.
• 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 abnormal condition is observed, immedi-
ately contact our authorized service provider nearest to you.

[3] Transportation
DANGER
• Do not stand directly under a unit suspended by a crane or other
lifting mechanism; otherwise, injury or death may result.
CAUTION
• Exercise ample care so as not to drop or tip over the unit during
transportation.
• When lifting the unit using eye bolts in the threaded holes pro-
vided on the main unit, refer to the package, exterior drawings,
catalog, etc., and do no lift a unit that is heavier than the rated
load of the eye bolts; otherwise, the falling/tumbling of the unit
or damage to the lifting devices may cause personal injury or
equipment damage.
• After the unit has been mounted in the machine, avoid lifting the
entire machine with using the eye bolts; otherwise, it may result
in injury or damage to the equipment due to the unit falling or
tipping over, or due to failure of the eye bolts.
• Use proper lifting xtures, and make sure the eye bolts and nuts
are not loose before lifting.

[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; otherwise, the cooling eect is reduced, possibly leading
to re or burns due to excessive heat built-up.
• Absolutely do not stand on or hang from the unit; otherwise, in-
jury or damage to the equipment may result.
• Do not touch the key slot at the end of the unit’s shaft with bare
hands. otherwise, injury may result.
• When the unit is used in food processing applications, machines
for cleanroom and so on, vulnerable to oil contamination, install
an oil pan or other such device to cope with grease leakage due
to breakdown or failure; otherwise, grease leakage may cause
failure of the unit, etc.
4-1 Place of Installation
Ambient temperature range
0 to 40°C ( the unit may be unable to start up under some r.p.m.
or torque condition when the temperature is very low.
Consult us if the unit is going to be used at temperature
levels close to 0°C).
Ambient humidity 85% or less. No condensation.
Altitude 1000m max.
Ambient atmosphere There should be no corrosive gas, combus-
tible gas, or steam.
The location should be free from dust and well ventilated.
Installation location Indoor ( free of severe dust and away from
water or other liquid splashes)
• Mounting in conditions other than the above requires adherence
to special specications. Please consult with us.
• Mount in a location that enables easy operation, such as inspec-
tion and maintenance.
• Mount on a suciently rigid member.
4-2 Installation Angle
No limitation in the installation angle.

[5] Mounting the servo motor
5-1 Motor assembly procedure
The product has a special shaft coupling between the reducer
gear and the motor so that a non-straight motor shaft such as key-
or D-shape-cut shafts can be accommodated.
Assemble the motor in the following steps from (1) to (8):
(In the case of a key-slotted shaft, remove the key before assem-
bly).
(1) Wipe rustproong or other oils from the motor shaft surface.
(2) Place the reducer on an appropriate work surface with the cou-
pling facing straight up.
(3) Remove the plug from the setting hole .
(4) Manually align the components so that the coupling tightening
bolt can be tightened from the setting hole .
(5) Insert the motor shaft into the center hole of the coupling .
Press the shaft straight into the coupling, and engage the joint
between the motor and the adapter plate .
(6) Lock the motor and the adapter plate together by tightening
the motor mounting bolt.
(7) Tighten the coupling tightening bolt from the setting hole us-
ing a torque wrench. Tighten to the appropriate torque value
shown on Table 5-1.
(8) Reinstall the plug from the setting hole.
