adjustment is necessary.
NOTE:
The starting position of spring retainer disc (A) is centered
within the U shape on indicator (B); however, the position
of the disc (A) will vary after draper tracking adjustment.

Adjust the draper tension by loosening jam nut (A) and
turning bolt (B) clockwise to increase draper tension or
counterclockwise to decrease draper tension. Retainer
disc (C) should be in the middle of indicator (D).
IMPORTANT:
For small tension adjustments, you may need to only adjust
one side of the draper. For larger tension adjustments and
to avoid uneven draper tracking, you may need to adjust
both sides of the draper equally.

If the draper is not tracking properly, retainer disc (C) can
be adjusted so that it is
NOT
in the middle of indicator (D),
but within the following range:
•
Loosened to 3 mm (1/8 in.), retainer disc (C) will move
towards the front of the deck from center of
indicator (D).
•
Tightened to 6 mm (1/4 in.), retainer disc (C) will move
towards the back of the deck from the center of
indicator (D).
