Manual adjustment 
NOTICE 
Manual adjustment may only be performed when the actuator is installed. 
■ The small actuator must be disconnected from the power supply 
when performing manual adjustment, which means at least one 
of the batteries must be removed. 
■ A hexagon key (key socket 4 mm) can be used to move the 
actuator into any position. 
NOTICE 
If you manually adjust until the slip clutch responds, turn the hexagon key half a turn in the opposite direction 
after the manually set stroke position has been reached.
