Sharpening knives
It is very important for the quality of woodchip that the knives are sharp. They must be checked at
least once a day. The grinding interval of the knives can be prolonged by grinding them regularly
with a carborundum stone.
The grinding process must be wet grinding with a header. Never use an angle grinder or a similar
tool for grinding the knives.
When grinding knives, ensure that the width of the knives in the set are uniform. Their widths
must be the same to keep the disc in balance. This means that the knives must always to be
ground in sets. The knives must not be ground down to a width of less than 75 mm. After that they
must be discarded.
The edge of the knives must be ground at an angle of 30°
