OPERATION
CAUTION
Check to be sure all bystanders have cleared the area.
2. Start the 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.
Figure 4.236: GSL
3. If necessary, relocate the clevis pin (A) at the frame
linkage as required to raise the center-link (B), so that
the hook is above the attachment pin on the header.
