3.
Check that the draper guide (the rubber track on the
underside of the draper) is properly engaged in the groove
of the drive roller, and that the idler roller is between the
guides.
4.
Turn bolt (A) clockwise to tighten the draper.
NOTE:
White indicator bar (B) will move to the right as the draper
is tightened. Tighten the draper until the white indicator
sits in the center of the window.
IMPORTANT:
To avoid premature failure of the draper, the draper rollers,
and/or the tightener components, do
NOT
operate the
DWA when the white tension indicator bar is not visible.
4.1.2
Adjusting Draper Tracking
The draper deck has one fixed drive roller and one spring-loaded idler roller. The spring-loaded idler roller is located at the
same end of the deck as the draper tensioner. Both rollers can be aligned with adjuster rods to adjust the draper tracking.
IMPORTANT:
The tracking of the draper on the Double Windrow Attachment (DWA) needs to be checked when the draper is first run up;
otherwise, damage to the draper may result.
