7. Press HEADER DOWN switch (A) on the ground speed lever
(GSL) to fully retract the header lift cylinders.
8. If the hydraulic center-link self-alignment kit is installed:
press REEL UP switch (B) on the GSL to raise the center-link
until the hook is above the attachment pin on the header.
IMPORTANT:
Ensure that the center-link is positioned high enough that it
does not contact the header as the windrower approaches
the header.
9. If the hydraulic center-link self-alignment kit is NOT
installed: relocate pin (A) in the frame linkage as needed to
raise center-link (B) until the hook 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.
10. Drive the windrower forward slowly, until feet (A) on the
windrower enter supports (B) on the header. Continue to
drive forward until the feet engage the supports and the
header is nudged forward.
