9.9 Knife pressure monitoring
The knife pressure on the McHale F5500 is monitored from the control box.
Knife pressure display
The knife pressure will increase to and stop at the normal working pressure of
50 - 60 bar which is displayed on the screen. The knife sensor symbol should also
appear on the screen to indicate that the knives are fully raised into the chopping
position. (On machines with the selectable knife option, a separate indicator is
displayed for each set of knives.)
Knife pressure too high warning
A warning will always be shown when the knife pressure is above working pressure.
Lower the knives, then raise again to reset to the normal working pressure.
This will be displayed if the knives lower even slightly while baling to warn the operator
of less than optimum crop chopping. The knives may be blunt or a hydraulic problem
may be causing the knife pressure to drop too low allowing the knives to retract.
WARNING: Do not bale if the knife pressure is too high!
Do not bale if the knife pressure is too high as machine damage will
occur!
