5. Use the following GSL functions to position the
center-link hook above the header attachment pin:

• Reel down (B) to lower the center-link
• Header tilt up (C) to retract the center-link
• Header tilt down (D) to extend the center-link
Figure 4.162: GSL
6. Adjust position of the center-link cylinder (A) with
the REEL UP and REEL DOWN switches. Position
the hook above the header attachment pin using the
HEADER TILT switches on the GSL.
IMPORTANT:
Hook release must be down to enable
self-locking mechanism.
If the release is
open (up), manually push it down after hook
engages header pin.

DOWN switch until it locks into position (hook
release [B] is down).
8. Check that center-link is locked onto header by
pressing the REEL UP switch on the GSL.

both cylinders stop moving.
