Fitting the Coupling
WARNING
Unprotected coupling.
Risk of severe injury!
●
Make sure that the coupling is protected by a cover or a guard.
In case of a machine supplied without a motor:
●
Fit a suitable coupling that matches the machine and motor shaft size.
●
Make sure that the coupling is sized to withstand the full motor torque.
●
Make sure that the coupling is correctly aligned according to the coupling instructions.
●
Install a protective cover or a guard.
