215184 284 Revision A
8.13 Adjusting Draper Tension
The drapers are tensioned at the factory and rarely need adjustment. If adjustment is required, tension the drapers just
enough to prevent slipping and to keep the draper from sagging below the cutterbar. Adjust drapers on both sides of the
header.
DANGER
To avoid bodily injury or death from unexpected start-up or fall of raised machine, always stop engine, remove key, and
engage safety props before going under machine for any reason.
