Product characteristics
•Only persons who have read and understand this manual may assembly, operate and maintain reducers. Further, the
persons operating with reducers must have qualification required for working with this type of devices.
•Responsible persons/managers/supervisors should prohibit to work with reducers to any person who do not
understand reducer as a product.
•If the end user of the product works in the military field or if the product is to be used for the manufacturing of
weapons, the product may be subject to trade controls and export regulations. Before the exporting of the product
therefore please check the export and trade control terms and conditions and take the required actions.
•If a fault or a malfunction of the product may directly endanger human lives or if the product is used in devices that
may damage the human health (nuclear, space, healthcare facilities, various security systems, etc.), regular checks are
essential. In such a case please contact our sales agent or our nearest business office.
•Although this product has been manufactured under strict quality control, if it is to be used in machines that, in
the event of a malfunction, may seriously endanger human lives or damage equipment, it is essential to adopt
appropriate safety measures.
•Installation should be done only by trained persons with knowledge of drive technology and mechanics.
•Before installing check if the reducer or its parts are not damaged.
•Be careful not to drop reducer on the floor or hit any metal object when moving as this can damage internal
component and cause malfunction of reducer.
•Do not hit any part of reducer with any tool e.g. hammer as this can cause damage to internal components
or malfunction of reducer.
•Do not use hammer or any impact tool to assemble reducer into its final position as this can damage internal
surfaces/components and cause malfunction of reducer.
•Do not touch reducer when running.
•Reducer will heat when running for certain period of time. Be careful not to touch its surface shortly after reducer
has stopped.
•Make sure the reducer with connected drive is turned off the power and cooled down before you exchange
lubricant, make any sort of checking or repair.
•Make sure that reducer and any connected component is not rotating/moving during maintenance, checking
or repair.
•Do not expose reducer to open fire or use in proximity of substances which are easily flammable or explosive.
•Reducers in standard version are not painted or covered with anticorrosive protection. Do not operate in humid
or corrosive environment as this may lead to damage of the reducer.
•Do not operate reducer outside of the specified technical parameters.
•Do not continue in operation if reducer is damaged or temperature on the case has exceed abruptly 60°C.
•Before disposal remove all of the lubricant from inside of reducer.
•Reducer should be disposed of in accordance with national regulations for industrial waste.

2.5 EU Directive 2006/42/EC
Reducer is a mechanical component only. It is used in machines and systems. Therefore, it is not a machinery or a partly
completed machinery within the meaning of the Directive 2006/42/EC of the European Parliament and of the Council.
A declaration of conformity is not therefore necessary for reducers.
Reducer must not be operated until it has been ensured that machine/system/device in which reducer is installed complies
in full with Directive 2006/42/EC.

3.4 Reducer lubrication
•The reducers as a standard are delivered lubricated with Castrol TRIBOL GR 100-0 PD or TRIBOL GR TT 1 PD grease.
Alternatively, the Castrol OPTIGEAR 150 oil may be used.
•When spline connection is used to connect motor with reducer, always use grease applied on the splined shaft.
Type of the grease is KLUEBER Microlube GL 261.
•The lubricant change interval highly depends on the individual operating conditions. High temperatures, speeds
and loading will reduce the service life of the lubricant. In many cases re-lubrication will not be necessary because
the reducer is filled for a long life. The recommended interval for lubricant change is 20 000 operating hours when
oil is used as a lubricant.
•Fully sealed reducers are always delivered pre-filled with lubricant. In case when open reducer is delivered,
consult our catalogue for proper amount of lubricant to fill in.
•Do not mix various types of lubricant in reducer. Doing so may cause damage or malfunction of reducer.
•Consult our catalogue or our customer service for detailed information about lubrication of reducers.
•The reducers should be transported in closed transport vehicles, in containers secured against movement
or overturning. The mode of transport should follow the mutual agreement between the customer and the supplier.
In addition, the product must be protected against the elements, aggressive vapors, dust, and mechanical damage.
The manufacturer recommends to store reducers in the original transport package.
•The standard packaging in the original package ensures corrosion protection for the period of 6 months during
storage in closed rooms with the ambient temperature from 5°C to 25°C and the relative humidity up to 60 %.
After 6 months it is necessary to preserve the reducer again.
•Never stand under suspended load as this possess risk of injury.
The warranty is specified in the General Delivery Terms of SPINEA, s.r.o. For more information visit our website: www.spinea.com

Product characteristics
•To get the maximum performance from the reducer, it is important to pay attention to the installation, assembly accuracy,
sealing and lubrication. Most motor adapter flanges are available on request, please contact the sales department or your local
sales representative for further assistance.
•Reducer is a single stage, zero backlash high precision gear which may be used only when properly assembled. The reducer
can be operated in horizontal or vertical position.
•The reducer surfaces are treated with corrosion inhibitor. Please remove all corrosion inhibitor from all surfaces which are to be
connected to the input and output components / devices. Inhibitor residues negatively impact friction coefficient of clamping
and bolt connections.
•To ensure safe connection of bolt connection we strongly recommend to use 10.9 quality screws and higher.
•Requirements on radial and axial runout with direct connection with motor shaft made according to DIN 42955R
are on the picture below. Please consult DIN 42955R standard for values of the tolerances.

•For the safe transmission of external loads applied to the reducers, it is required to use connecting screws of at least 10.9 grade
and to degrease contact surfaces of friction joints before the installation. Tightening torques of screws are shown in the table
below.
•Allowable torques transmitted through connecting screws on flange and case are shown in the table below.

•Make sure that all bolt holes, screws and connecting adjacent surfaces are free of grease and dirt.
•Assemble the motor flange to the input side of the reducer, use prescribed tightening torques.
•Make sure that the splined shaft on the motor or the spline adapter is greased with special grease (see chapter
3.4 Reducer lubrication). Failure to do so will damage splined connection.
•Slide the spline adapter on motor shaft, pull over the clamp ring and tighten with correct tightening torque. Use tightening
torque specified by clamp ring manufacturer.
•Slowly insert the motor with spline properly oriented into the reducer input shaft. Please do not use excessive force or impact
to get the motor into a final position. Use gentle movement to adjust the splined shaft into counter-surface inside of the input
shaft.
•Center the motor and tighten the bolts connecting motor to the motor flange.

6. Service
•Run the reducer only within its specified technical parameters.
•Use reducer in clean and dry environment.
•Operate the reducer within defined ambient temperature range -10°C to +40°C. Please contact manufacturer when
operating conditions are outside of those limits.
•Ensure that temperature of the reducer surface does not exceed 60 °C. In case your application requires higher running
temperatures on the surface of the reducer contact manufacturer.
•Check reducer for leaks. Sometimes excessive lubrication from sealing dustlip will cause small leakage, wipe it out
and observe if leakage continues.
•Check for noise during running-in and periodically when operating the reducer.
•To request service or information concerning reducers please contact our office listed below.
