Shaft extensions

Caution
Damage to the motor and the rotor!
The ball bearings of the motor and the counterbalanced rotor may be damaged by forceful impacts in the
assembly of the rotor and/or the shaft extension.
♦ Attach the rotor and/or the shaft extension to the shaft or the rotor without forceful impacts.
Note:
The hub can be heated for easier assembly and dismantling, for example with a hot-air blower.
• Precondition for assembly: the wedge is in the intended groove.
• Tools: matching hexagonal wrench and suitable tool for removal, torque wrench for the taper clamping
bush.
