Unlocking the telescoping cylinder
If the telescopic section is locked (typically indicated by

telescoping cylinder.
• Select and confirm the symbol (3, (Figure 3-65)).
The telescoping cylinder is unlocked. In the unlocked
position, the screen should appear as indicated by
(Figure 3-69). The telescoping cylinder is unlocked from any
telescoping boom section (unlock symbol shown near the
graphical representation of the tele cylinder - refer to Item 1
in (Figure 3-65)).
The telescoping boom section is locked (the unlock symbol
is not shown near the graphical representation of the section
pins - refer to Item 2 in (Figure 3-65)).
In the top row of the proximity switches, S2112N is on, the
others in the row are off. In the middle row of the proximity
switches, S2118N is on, but the others are on or off
depending on the location of the tele cylinder with respect to
telescoping boom sections.
You can now move the telescoping cylinder into the next
telescopic section, refer to (Table 3-3.) for the expected
value for the precision length sensor (Item 2 in (Figure 3-64))
