Knives
The wood chipper is fitted with four knives.
The knives must always be changed as a set. The knives belong together in sets, also when they
are ground so that they are always of equal width. If the knives are not of equal width, the disc will
be out of balance, which will lead to unnecessary strain on the bearings and vibrations in the
whole wood chipper.
Replacing the knives
1.
Open the disc housing as described in chapter 7.
2.
Remove the bolts (2) that hold the knives and clamping plates (3)/sliver breaker securely to
the disc.
3.
Remove the knives and sharpen/replace.
4.
Carefully clean the knives (1), clamping plates (3)/sliver breaker and contact faces.
5.
When fitting the knives (1), the bolts (2) must be lightly oiled (
m
=0.125), i.e. light oil, WD 40
or an equivalent product. Do not use copper grease, MoS
2
or similar low friction grease.
6.
Check that the distance between the knife edge and the counterknife is set correctly to
D
(see chapter 10). Check all of the knives.
7.
Tighten the bolts (2) to
110 Nm / 11 KPm
. Use a torque spanner for this purpose (available
as extra equipment).
8.
Finally, close the disc housing as described in chapter 7.
