1. Remove the hairpin (A) from pins (B) and remove the
pins from header legs.
CAUTION
Check to be sure all bystanders have cleared the area.
2. Start engine and activate HEADER DOWN button (A)
on the ground speed lever (GSL) to fully retract header
lift cylinders.
IMPORTANT:
If the center-link is too low, it may contact the header as
the windrower approaches the header for hookup.
3. 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.
4. Ensure that lift linkages are properly engaged in header
legs, contacting the support plates.
5. Stop engine and remove key from ignition.
