11. Drive the windrower slowly forward until draper header
supports (A) enter header legs (B). Continue driving slowly
forward until the lift linkages contact the support plates in
the header legs and the header is nudged forward.
12. Ensure that the lift linkages are properly engaged in the
header legs and are in contact with the support plates.
13. Windrowers equipped with the self-aligning
center-link kit:
a. Adjust the position of center-link cylinder (A) with the
switches on the GSL until hook (B) is above the header
attachment pin.
IMPORTANT:
Hook release (C) must be down to enable the self-
locking mechanism to function.
b. If hook release (C) is open (in the up position), shut
down the engine, and remove the key from the
ignition. Manually push hook release (C) down after
the hook engages the header pin.
c. Lower center-link (A) onto the header with the REEL
DOWN switch on the GSL until the center-link locks into
position and hook release (C) is down.
d. Check that the center-link is locked onto the header by
pressing the REEL UP switch on the GSL.
14. Windrowers without the self-aligning center-link kit:
a. Press the HEADER TILT UP or HEADER TILT DOWN
cylinder switches on the GSL to extend or retract the
center-link cylinder until the hook is aligned with the
header attachment pin.
b. Shut down the engine, and remove the key from the
ignition.
c. Push down on the rod end of link cylinder (B) until the
hook engages and locks onto the header pin.
IMPORTANT:
The hook release must be down to enable the self-
locking mechanism to function. If the hook release is
open (in the up position), manually push it down after
the hook engages the pin.
