Mounting with grub screws

If the linear actuator is to be mounted to the
groove of the mounting shaft, at least one grub
screw must be used.
1. Make at least one threaded hole in the me-
chanical mounting across from the groove
(for dimensions, see manual).
2. Insert the linear actuator into the mechani-
cal mounting.
3. Screw a grub screw into each threaded hole
