Draper Tension Adjustment:
Draper tension should be just enough to prevent
slipping and keep draper from sagging.
Set draper tension as follows:
1. Check that draper guide (rubber track on
under- side of draper) is properly engaged in
groove of drive roller and that idler roller is
between the guides.
2. Turn bolt (A) clockwise (tighten) and white
indicator bar (B) will move to the right in
direction of arrow to indicate that draper is
tightening. Tighten until bar is about halfway
in window.
IMPORTANT:
To avoid premature failure of
draper, draper rollers and/or tightener
components, do not operate with tension set
so that white bar is not visible.
Draper Tracking Adjustment:
The draper deck has one fixed roller and one
spring-loaded roller. The spring loaded roller is
located at the same end of the deck as the
draper tensioner. Both rollers can be aligned by
adjuster rods.
If the draper is tracking incorrectly, make the
following adjustments to the rollers:
