IMPORTANT:
Insufficient hold-down clearance will result in the knife and the guards overheating.
7.10.5 Checking Hold-Down – Short Knife Guards
The short knife guard hold-downs prevent the knife sections on the cutterbar from lifting off of the guards, while still
allowing the knife to slide. The hold-downs will need to be inspected to ensure that there is adequate clearance between
the hold-downs and knife sections.
To check the center hold-down on double-knife headers, refer to
page
193.
