

Run the platform to the stowed position.



Adjust the eccentrics as shown in Figure 30. By doing this, the li-

near lift has the least possible range of movement before the ar-

rester hooks engage.

Micro-Switches

A total of three micro-switches are installed in the carrier arms of

the linear lift. They are actuated by the abrasion protectors on the

elbow joints (see Figure 31 and Figure 32).
