3. If necessary, relocate the pin (A) at the frame linkage as
required to raise the center-link (B) so that the hook (B)
is above the attachment pin on the header.
IMPORTANT:
If the center-link is too low, it may contact the header as
the windrower approaches the header for hookup.
4. Slowly drive the windrower forward so the boots (A)
enter the header legs (B). Continue to drive slowly
forward until lift linkages contact the support plates in
the header legs and the header nudges forward.
5. Ensure that lift linkages are properly engaged in header
legs, contacting the support plates.
6. Activate HEADER TILT cylinder switches on ground
speed lever (GSL) to extend or retract center-link
cylinder so that the hook lines up with the header
attachment pin.
7. Stop engine and remove key from ignition.
