Improper assembly, commissioning and maintenance of the coupling.
Operation of the coupling with defective protection guards or improperly mounted or
non-functional safety and protection devices.
Failure to observe the notes in the operating instructions regarding transportation,
storage, assembly, commissioning, operation, maintenance, cleaning and disassembly
of the coupling.

Safety
Proper use
The highly flexible Reich TOK coupling has been specially designed for applications
requiring extremely low torsional stiffness. Furthermore, it is particularly well suited to the
compensation of axial and radial displacements of resiliently mounted drives. The wide
range of flexible coupling elements and adaptive designs provides standard solutions for a
wide variety of different tasks. These can be complemented by specific customised
designs on request. The flexible element is designed to combine high torque transmission
capacity and high displacement capacity with high speed capability. Its stiffness can be
adapted to requirements by selecting different rubber qualities. The adaptive designs are
based on the standard flywheel adapter dimensions according to SAE J 620.
Proper use also includes the observance of and compliance with all details contained in
these operating instructions and the related documents. This applies, in particular, to both
the safety instructions and the warning notices, and to the adherence to the cleaning and
maintenance intervals.
Any other use or any use beyond the limits of proper use is deemed improper use and can
lead to property damage or personal injury.
The following types of use, in particular, are deemed improper use:
Operating the coupling outside its operating limits, and especially at too high
rotational speeds and/or torques or continuous fatigue torques.
Operating the coupling in a substandard condition.
Having the coupling operated by inadequately trained personnel.
Operating the coupling with deactivated and/or modified protective guards.
Operating the coupling with modified add-on parts.
Improper cleaning with cleaners containing solvents, alkalis or acids.
Improper operation of the coupling results in forfeiture of the liability for material defects
and warranty.

Duties of the owner
The owner of the coupling is bound by laws and regulations to issue instructions which
ensure safe operation.
The owner must define a “responsible person”. Only this person is authorised to issue
a work clearance permit for working on and with the coupling. Work on the coupling
described herein must not be executed unless the written work clearance permit for
the execution of that work is available from the responsible person.
The owner of the coupling must ensure that only qualified and authorised personnel
performs the following activities on and with the coupling:
−Transportation
−Storage
−Assembly
−Putting into operation
−Operating
−Decommissioning
−Cleaning
−Servicing
−Disposal.
Persons whose ability to react is affected, for example, by the use of alcohol,
medicines, drugs, etc., must not work on or with the coupling.
The owner of the coupling must regularly train the personnel working on the coupling
in the following areas:
−Use of the personal protective equipment
−Safe working practices
−Applicable accident prevention regulations
−Hazards arising from the coupling whilst in operation
−Behaviour in an emergency
−First aid measures.
The owner must ensure that the applicable country-specific laws and guidelines
including the health protection regulations, the occupational health and safety
regulations and the fire prevention regulations, are adhered to.
The owner must ensure that personnel receiving training, hands-on training, briefings
or making an apprenticeship exclusively works on and with the coupling under the
constant supervision of an experienced specialist.
The operator must ensure that the coupling is enclosed by an adequately dimensioned
separating protective guard which can withstand a coupling rupturing. It must allow
sufficient ventilation of the coupling; see page 72.
Before commissioning the coupling, the owner or a person authorised by the owner
must ensure that the following requirements are met:
−Proper use of the coupling must be ensured.
−All protection devices must be properly mounted and functional.
−All safety regulations must be adhered to.
