Warning :
Remember: When shredding at temperatures around freezing,
maximum branch size of branchy material is limited to 70 mm.
9.6.3 ABM system
The machine comes as standard with an anti-block motor system (ABM).
• This ABM system monitors the performance of the engine and will automatically intervene
when the speed falls below a critical rpm level by regulating garden waste supply.
• Result:
• The machine is overload protected.
• The machine will autonomously check its operation and the operator needs
only to concentrate on the in-feed of material.
• Less consumption and improved effi cient operation.
• The discharge belt conveyor will always discharge material with a constant speed. The anti-
block motor system (ABM) will not affect the operation of the output conveyor.
9.6.4 Tips for correct use
The ABM-system entails great comfort of use for the operator but, in certain situations, the ABM
system may need assistance in that the operator must be involved when the machine fl ashes:
• The ABM system will continuously switch on and off the feed when processing long and thick branch-
es that have the maximum diameter (100 < > 140 mm) over the entire length. Every time the engine
speed picks up again, the ABM will again start the feeding and the machine will again process the full
load. Since we are here dealing with the limit of what the machine can do, a small additional effort is
suffi cient for the machine to encounter problems. The operator should be in the vicinity as a precau-
tionary measure so that he or she can manually intervene if the machine should threaten to jam:
• You can then modify the material feed speed;
• Alternatively, you can switch off the feed for a short period by pulling the control handle one
position backwards (position 1) or by pressing the control handle one position forward (position 3).
• The wood can, if required, be returned by pressing the control handle forwards (4) and the redi-
rect the branch and have it fed in again.
The ABM system acts only on the feed roller and the feed belt. However, neither the ABM system
nor the operator can manipulate garden waste that has gone through the feed roller. This is why
the operator must already avoid problems when introducing material in the feeding hopper with
regard to certain types of garden waste:
• With irregular branches (nodes, forked branches), ensure to feed them to the feed roller in an
optimal position. Stop, if required, the roller and reposition the branch halfway to ensure that the
machine cannot jam.
