2. Storage
When storing Hyponic drives 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 changes or
corrosive gas.
2–2) Storage Period
(1) Storage period should be less than 1 year.
(2) When the storage period exceeds 1 year, special rust prevention is necessary. Contact
the factory for details.
(3) Export models need export rust prevention. Contact the factory 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 Hyponic drives or reducer, verify that there is no abnormal sound,
vibration or heat built-up. If supplied as a brakemotor verify that the brake operates
properly. If any anomaly is observed, contact our nearest agent, distributor or sales office.
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 gearmotor or reducer. When a hanging bolt or
hole is provided, be sure to use it. After mounting a cyclo 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 Hyponic drives or 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.

Water proof/Dust proof type
Note) IP65 is not available for underwater or high water pressured condition.
COMMON
DANGER
Do not use a standard unit in an explosive atmosphere (which is likely to be filled with
explosive gas or steam). Under such conditions, an explosion-proof motor should be used;
otherwise, electric shock, personal injury, fire, explosion, or damage to the equipment may
result.
4. Installation
CAUTION
Do not use the cyclo gearmotor for purposes other than those shown on the rating plate or
in the manufacturing specifications; otherwise, electric shock, personal injury, or damage
to the equipment may result.
Do not place flammable objects around the gearmotor; otherwise, fire may result.
Do not place any object around the gearmotor; that will hinder ventilation; otherwise,
excessive heat may build-up and cause burns or even fire.
Do not step on or hang from the gearmotor; otherwise injury may result.
Do not touch the shaft end of the gearmotor, 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 breakdown;
otherwise, oil leakage may damage products.
4–1) Installation Location
Ambient temperature: -10°C to +40°C
Ambient humidity: 85% max.
Altitude: 1000 m max.
Ambient atmosphere: There should be no corrosive gas, explosive gas, or steam.
The location should be well ventilated without dust.
Installation location: Indoors, with minimal dust and no water contact.
IP65: The IP indication that represents dust-proofing and water-proofing grades is prescribed
by IEC529 and IEC34-5. "6" of IP65 represents a "perfect dust-proofing structure" that
is the highest-grade protection from contact or entry of solids, while "5" represents
protection from water, ensuring protection from water jets in all directions.
The motor has a structure that permits motor operation without any trouble even if it is
exposed to water jets in all directions from a nozzle.
Test conditions: A nozzle of 6.3 mm in I.D. is placed at a distance of 3 m from the test piece
and water jetted out of the nozzle under pressure of 30 kPa at the flow rate
of 12.5 l/min is directed at the test piece in all directions for three minutes.
After that, there should be no abnormality. The motor cannot be used
underwater or in places exposed to high-pressure water jets.

(a-1) How to set the shaft (03#, 07#, 17#, 1010#)
Apply molybdenum disulfide grease to the surface of a driven shaft and the inner
surface of a hollow shaft. Then insert the Drive into the driven shaft.
If the fitting is too tight, lightly knock the end face of a hollow output shaft with a
wooden hammer for smooth insertion. Do avoid knocking the casing. We recommend
making a jig shown Fig 2. Using this jig, you can insert the Drive smoothly.
COMMON
4–2) Installation Angle
There is no restriction on the installation angle.
(For outdoor type gearmotors, standard installation angle is horizontal in the axial direction.
Contact us for other axial directions.)
· 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 units where inspection, maintenance, and other such operations can be easily carried
out.
· Install units on a sufficiently rigid base.

(c–1) How to set a torque arm (03#, 07#, 17#, 1010#)
Mount a torque arm on the driven machine side of the Drive casing. Use hexagon
socket head bolts for mounting. (See Table 3 for bolt sizes.)
Torque arm anti-rotation stopper should be designed so as to allow movement of the
torque arm to make sure that the contact surface between the Drive and shaft are free
from excess force.
Don't fix the torque arm by anti-rotation bolts.
For such applications as requiring frequent start and stop or frequent reversing of the
rotating direction, insert a rubber bushing between the torque arm and securing bolt (or
spacer) in order to relax impact load.

CAUTION
Confirm the rotation direction before coupling the unit with the driven machine. Incorrect
rotation direction may cause personal injury or damage to the equipment.
When operating the gearmotor alone (uncoupled), remove the key that is temporarily
attached to the output shaft; otherwise, personal injury may result.
Cover the rotating parts; otherwise, personal injury may result.
When coupling the gearmotor with a 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, personal
injury may result because of misalignment.

· 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
greater.
· Install sprocket and gears so that their point of load application will be closer to the
gearmotor side with respect to the length of the shaft. (Fig.24)
(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,. (Fig25)
· Use a matched set with the same circumferential length when more than one belt is to be
installed.
