by feeding +24V power to the floating valve solenoid 122 on left side main cylinder.
Use adapter cable MU113937001.

If the hooklift is not equipped with preinstalled oil reservoir, then open the plug from the tank
line connector on the control valve before activating the solenoid and catch up the oil
(max. 1 pt).
If the hooklift is equipped with preinstalled oil reservoir, the tank connector does not need to be
