Service Maintenance
4. Sieve box drive
The sieve box drive belt differs
slightly from the others on the
machine in that to check the
tension of the belt the nut, B,
needs slackening, then the
spring length F can be set to
the guide D. If nut B is not
slackened, the pulley will look
to be at the correct tension,
even if this is not the case.
5. Chopper stops and belt
Make sure the chopper beltis
tensioned daily and that the
chopper stops shown in the
picture are pushed upwards
so they make contact.
TIP. Do not force the stops up, this will not increase the tension on the belt.
