McHale F5500 Baler

Door charge valve
1. Remove all unfinished and finished bales from the baling chamber.
2. Loosen the lock nut on the adjustment screw (A).
3. Inspect the existing pre-charge pressure by holding the spool to close the back
door for 3 seconds.
4. If pressure must be increased (gauge in the yellow zone) turn the adjustment
screw (A) clockwise and if the pressure is to be decreased turn the adjustment
screw anti-clockwise.
5. Continue to inspect the gauge and once the indicator needle is at the desired
setting, tighten the lock nut on the adjustment screw ensuring not to let the
adjustment screw itself rotate and close all protective covers.
The grass-silage/hay-straw door sensor handle is located inside the right-hand side
door panel, close to the door hinge. The bale chamber features a quick adjustment
sensor position plate. This allows for a quick change to lower density bales as required
for hay and straw, without any need to adjust the chamber pre-charge pressure. In
effect, it limits the level to which the chamber pressure will climb above the pre-charge
pressure during baling of hay and straw.
9.14 Bale size adjustment
McHale recommend that the bale size should be between 1.25 m and 1.29 m. The bale
size may vary depending on density setting, crop volume intake, chop length, stopping
distance, netter settings, amount of net applied and bale size sensor adjustment.
CAUTION:
Never adjust chamber pre-charge pressure above 170 bar
The chamber pre-charge pressure should never be adjusted above
170 bar pressure in any case, damage to machine components may result!
