Note
Using the eyebolts
The 1FL609❑ motor (90 mm shaft height) has two M8 screw holes for screwing in two
eyebolts. Lift the 1FL609❑ motor only at the eyebolts.
Eyebolts that have been screwed in must be either tightened or removed after mounting.
To ensure better heat dissipation, install a flange between the machine and the motor. You
can install the motor onto the flange with four screws as shown in the following figure.
The information about the screws and the flange is as follows:
