WARNING
Risk of injury due to Incorrect installation or removal
The feather key may be flung out if the motor is operated without drive output elements, such
as coupling, etc. Carefully comply with the required measures.
This can result in death, serious injury or material damage.
• The general touch protection measures for drive output elements must be observed.
• Only operate the machine with the drive output element mounted.
• Drive output elements may only be pulled on or pulled off with the correct equipment.
• The feather keys are only locked against falling out during shipping. For test operation or
when commissioning without drive output element, carefully secure the feather key
using a suitable locking element. When doing this, take into account the type of machine
balancing.
Pulling on drive output elements
• Requirements:
– The coupling and/or the drive output element must be appropriately dimensioned for the
operating case at hand.
– Observe the coupling manufacturer's instructions.
– Make sure that the balancing type of the drive output element correctly matches the type
of balance of the rotor.
– Use only ready drilled and balanced drive output elements. Check the hole diameters and
the balancing status before pulling them on. Thoroughly clean the shaft extension.
• Pulling on:
– Heat up the drive output elements to expand them before pulling them on. Select the
temperature difference for the heating process to suit the coupling diameter, fit and
material. Observe the coupling manufacturer's instructions.
– Drive output elements may only be pulled on or pulled off with the correct equipment.
The drive output element must be pulled on in one continuous operation via the front
thread holes in the shaft or pushed on by hand.
– Do not use a hammer, as this will damage the bearings.
