Attention!
Do not use the antirotation
strap from the KM actuator!
(insufficient stability)
Note :
If LM... actuators are mounted on round
spindles less than 35 mm long, it is
important to:
1. use the LM...-F form-fit version
2. use the K5 spindle clamp adapter
The K5 comes with:
• Spindle clamp adapter
• LM antirotation strap
