6. Lubrication
6-1) Shippingcondition
• theseproductsunitsareshippedwithoutoil.Supplyrecommendedoilbeforeoperation.
6-2) Methodoflubrication
The oil splash lubrication method is used for these products.
Under certain conditions, grease or forced lubrication should be used.
(1) Splash lubrication
Standard input shaft rotating speed range 450 ~ 1800r/min.
(2) Forced lubrication
CAUTION
● For a system inwhich a lubricant motor pump is provided separately, switch on the pump motor prior to
switching on the reducer motor. This will enable proper lubrication of the bearings prior to start up.
Failure to do so may damage the unit.
Useaowswitchand/orsighttoverifythatlubricantiscirculating,andforemergencymotorstopifnecessary.
(3) Grease lubrication for bearings
Greaselubricationwillberequireddepending on an operatingcondition.Insuchcase,thelocationandnumberof
greasenipplesshouldbeconrmedinadvance.Thebearingsarepackedwithgreaseatthetimeofshipment.
Supplygreaseaccordingtotheinputspeed-every1500hourswhentherevolutionisunder750r/min,andevery1000
hourswhentherevolutionis750-1800r/min.

6-5) Oilsupply
Supplyoilthroughthellingportatopthemainunit.Checkthe
oil level with a visual oil gauge. (Fig. 5) Exercise care when
supplying oil to ensure that loose nuts, bolts, washers, dust,
water, and other foreign substances will not enter the unit.
Ifoillevelislowerthan thespeciedrange,lubricationwillbe
insufcient.Incasetheoillevelishigher,deteriorationofoilis
accelerated due to oil temperature rise.
6-6) Wasteoil
Remove the drain plug under the main unit to drain waste oil while it is still warm.
(i. e. Soon after operation of the unit has ceased. But not immediately after.)
7. Backstop
Useofabackstop(optional)istopreventreverserotationofthecoolingfan.
Backstopislocatedinternally.Backstopislubricatedbytheinternalgearoil.
The oil level shall be
within this range.

8. Operation
DANGER
●Neverapproachortouchanyrotatingparts(shaft,etc.)duringoperation.Looseclothingcaughtintheserotating
parts may result in severe injury and/or death.
CAUTION
● Checktheoillevelwiththeoilgaugebeforeoperation.
● When usingpole changemotors tochange fromhigh speed tolow speed,control thefan rotationspeedso that
regenerationbrakingtorquedoesnotactonthereducer.
● Ifthereducerhas abackstopinstalledandthereduceris notoperatedforanextendedperiod,operatetheunita
minimumof5minutesforevery200hoursofnon-operation.
●Thereducerwillgetveryhotduringoperation.Donottouchorcomeincontactinany way with the reducer;
otherwise, you may suffer burns.
● Ifthereducerisoperatinginanabnormalway,stoptheunitimmediatery;otherwise,electricshock,personalinjury,
orremayresult.
● Donotoperatethereducerinamannerthatexceedsitsratingcriteria;otherwise,injuryordamagetothesystem
may result.
● Donotremoveanycoversoropenthereducerduringoperation;otherwise,splashinglubricantmaycauseburns.
● Donotloosentheoilllerplugduringoperation;otherwise,splashinglubricantmaycauseburns.
 Whenreversingthedirectionofrotation,rstbringtheunittoacompletestop,thencommencereverserotation;
otherwise, the system may be damaged.
Afterinstallation,checkthefollowingpointspriortooperation.
(1) Istheoillledtothecorrectoillevel?
(2) Isthereducercorrectlycoupledwiththematingmachine?
(3) Arefoundationboltsrmlytightened?
(4) Doesthedirectionofrotationconformtotheonespeciedanddesignedfor?
Afterconrmingtheabove,allowforano-loadbreak-inperiod.Thengraduallyapplythedesignload.
Atthistime,conrmthefollowing:
Table 6
Itemstobecheckedduringbreak-inperiod/possiblecauses.
Abnormal sound
and vibration
(1) The housing is deformed because the installation surface is irregular.
(2) Resonanceisoccurringduetothelackofrigidityoftheinstallationbase.
(3) The shaft center is not properly aligned with the motor.
(4) The vibration of the fan is transmitted to the reducer.
The surface
temperature of the
reducer is
abnormally high.
(1) The motor current has exceeded the rated current shown in the rating plate.
(2) The voltage rise and drop of the motor is too large.
(3) The ambient temperature at which the reducer is operating is too high.
(4) Theoilisnotatitsspeciedlevel(toolowortoohigh).
Whenananomalyisfound,stopoperation,andcontactthenearestagent,dealer,orserviceofce.

9. Daily inspection and maintenance
DANGER
●Neverapproachortouchanyrotatingparts(shaft,etc.)whenmaintainingorinspectingthereducer during
operation.
Loose clothing cought in these rotating parts may result in severe injury and/or death.
● Besure tostopboththe drivinganddriven machinesbeforecheckingany toothsurfaces;otherwise, youmaybe
caught in the gear engaging section, resulting in severe injury and/or death.
● Donotoperateanyunitswithoutall(safety)coversinplace.Failuretodosomaycauseinjuryand/ordeath.
CAUTION
● Thesurfaceofthereducerwillgethot,donottouchthereducer;otherwise,aburnmayresult.
● Donotchangetheoilduringoperationorsoonafteroperationhasceased;otherwise,thehotoilmaycauseburns.
●Donotremoveanycovers or open thereducerduringoperation;otherwise,splashing hot lubricantmaycause
burn.
● Changelubricantaccordingtothemaintenancemanual,anduseonlythoserecommendedlubricants;otherwise,
the system may be damaged.
● Donotoperatedamagedproducts;otherwise,injury,re,ordamagetothesystemmayresult.
● We cannot assume any responsibility for damage or injury resulting from an unauthorized modification by a
customer.
9-1) Dailyinspection
To ensure proper and contined optimum operation, use the table below to perform daily inspections of the unit.
Table 7
Inspection item Details of inspection
Noise Is there abnormal sound or sudden change in the noise characteristics during
operation?
Vibration Is there any abnormal vibration or sudden change in the vibration of the
reducer?
Surface temperature
Isthetemperatureof thesurfaceofthereducerabnormallyhigh?Orisit
risingrapidly?
The temperature rise during operation differs according to the type of
reducers. A surface temperature of approx. 80°C (176°F) will not cause any
adverseeffectsaslongasitdoesnotrisesignicantlyabovethislevel.
Oil level
Istheoilleveldecreasing?
(Checktheoillevelwithadipstickorvisibleoilgaugewhenthereducerisnot
operating)
Oilleakage Isoilleakingfromtheoilsealorothersections?
Foundation bolt Haveanyboltscomeloose?
Whenanyabnomalityisfoundduringdailyinspection,takeappropriatecorrectivemeasuresbasedon"10.Troubleshooting
(P.9)"
Ifnormaloperationisstillnotpossible,contactthenearestagent,distributor,orserviceofce.
9-2) Changeoflubricant
(1) Changeoil500hoursor6monthswhichevercomesrstafterinitialstart-up.
(2) Incaseoftheoiltemperatureisbelow80°C(176°F),a8000hoursor1year(Whichevercomesrst)changeintervalis
recommended.
(3) In case of the oil temperature is above 80°C (176°F), a 4000 hours or 6 months (Whichever comes first) change
interval is recommended.
Deterioration of the oil will be accelerated when the ambient temperature changes rapidly or the ambient atmosphere
contains corrosive gases. In these situations consult with the lubricant manufacturer.
