OPERATION
3. If necessary, activate the REEL UP switch (A) on the
GSL to raise the center-link, so that 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
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.
