Replacing Pointed Guards and Hold-Downs
Check daily that guards are firmly bolted to the cutterbar, and not worn or broken. Replace broken guards as required. A
worn or broken guard can be replaced without removing knife from cutterbar. This procedure describes the replacement of
pointed guards and hold-downs on single- and double-knife headers.
DANGER
To prevent injury or death from the unexpected start-up of the machine, always stop the engine and remove the key
from the ignition before leaving the operator’s seat for any reason.
