The chain should be cleaned regularly.
To clean the chains, brush with a coarse brush to remove any dirt. Wash the chain in
benzene, kerosene or similar solvent and soak it in this for 24 hrs. After this the chain
should be clean, if it is, it will no longer make any scratching sounds when the links
are moved.
In order to lubricate the chain, it should be submersed in a bath of good quality motor
oil and moved around.
Prior to re-installation the sprockets must be cleaned thoroughly.
8.10 Rotor wear plates (optional)
The wear plates (counter knives) underneath the knives should be observed at every
knife change. They must be replaced before the wear reaches the rotor body. These
wear plates must be changed as a set, to prevent rotor imbalance.
8.11 Feedrolls
The wear of the feedroll teeth should be observed, short round teeth affect the indeed
and therefore the chip quality. The two feedrolls just ahead of the rotor show usually
the strongest wear.
In order to fully utilise the life of all feedrolls, they can be exchanged with other rolls
showing less wear. There are two types of feedrolls and any roll must be replaced by
a roll of the same type.
The cleaning comb installed between rotor and lower first feedroll usually experi-
ences a lot of wear and must be replaced when worn. The cleaning comb on the up-
per feedroll does not usually receive a lot of wear.
