SHARP BLADES = MAXIMUM OUTPUT
• Before performing any maintenance, stop the machine
Warning:
The blades may continue to rotate for a few seconds after the motor is switched
off. Always check whether the blade shaft has come to a complete standstill.
Caution:
Always wear gloves since blades can be razor-sharp
• Open the shredding chamber (“read § 16.2 Opening and clos-
ing the shredding chamber” on page 50).
Pay particular attention to the following:
Garden waste chipping with the ELIET chipping system takes
place in two steps. We first have the contact of the blades
with the garden waste when chopping takes place where the
cutting block can be found. The wood and garden waste is cut
in large, rough and irregular chippings during this
primary
chipping (1)
. These large chippings will, subsequently, end
up in the shredding chamber where they are finely chopped
to produce small chippings. This
secondary chipping (2)
will continue until the chippings are considered to be small
enough to pass through the openings of the calibrating sieve.
Each of these chipping actions set certain criteria that the blades
must meet for optimal chipping efficiency:
A)
The top of the blade, in particular, is important with regard
to the primary chipping. Since the blades act as splitting
blades, the cutting angle is essential because this forms the
key that will cleave through the wood. The
cutting angle
of
the cutting edge of the blade is by preference 30°. The sharp-
er the blade edge, the less resistance when splitting and the
smaller the cutting impact on the structure. This will ensure
considerably fewer vibrations and noise. This will also benefit
the load on the blade shaft and the bearings. The blades must
be regularly ground to guarantee the optimum cutting angle.
