Feeding Material into the Machine.
Ensure that no contaminated material is fed into the Chipper. Metal, stones, sand and dirt will harm
the cutting edge of the blades, leading to undesirable performance. Avoid feeding stringy materials
such as cabbage trees into the Chipper as these can wrap around the cutter shaft bearing, damaging
the seals.
Avoid feeding short pieces of wood into the Chipper. These short pieces tend to bounce off the
cutting disc and act erratically. To chip these short pieces of material, combine their feeding with
larger lengths of wood.
Freshly cut green material will be cut more efficiently that old wood which has dried over an
extended period.
The maximum diameter of branches that the Chipper can process is 40mm, depending on the
hardness of the wood. The Chipper has been designed to self-feed the material into the cutting
blades. Because the Chipper has a large inlet chute, larger material has the tendency to stall the
machine. To aid in stopping this, manually feed these larger branches down the chute, allowing the
engine to maintain a high speed to effectively cut the material without stalling.
Ensure that the material is fed into the inlet chute wooded end first, leaving the leafy end to be
pulled through. This aids in the self-feeding of the machine and helps the bushy material be
effectively cut. Some of the smaller growth coming off the main branch may need to be trimmed so
that it doesn’t get jammed at the bottom of the inlet chute. As the operator becomes more familiar
with the machine, they will be able to judge which branches need to be trimmed.
If material becomes clogged at the bottom end of the inlet chute, use a spare branch to push the
blocked material down into the cutting blade. Ensure that the spare branch is of sufficient length so
that the operator does not have to reach inside the chute.
The Chipper is able to process material other than just branches. Leaves, prunings and vines can be
fed into the Chipper.
Unclogging the Cutter
If the Chipper stalls through overloading or clogging, stop the engine, ensure that the cutting disc
has completely stopped and the ignition switch is in the OFF position and the spark plug
disconnected. Open the cutter housing cover and remove all the material from the housing. Close
the cutter housing, and restart the machine. Refer to the starting procedure at the beginning of this
section for guidance. If any stringy material becomes wrapped around the rotor shaft, remove it
before it works itself into the bearing.
