When taking samples at the cleaner outlet, it is
recommended to collect the entire grain flow for a
short moment before selecting the desired quantity
from the collected grain.
The grading rate of the sample is found by means
of test screens. If the percentage is too low, reduce
the capacity, and if it is too high, increase the ca-
pacity. As crops will vary, however, it will be wise to
allow for a minor safety margin.
If the capacity is changed, new samples will have
to be taken. Continue this way until the desired
grading result of the finished product has been
obtained. When the correct capacity setting has
been reached, it is recommended to deliver a sam-
ple of the finished product to the feedstuff dealer for
testing, as the test screens are intended as a guide
only.
Service and maintenance:
Bearings
All bearings are lubricated for life from the factory,
and requires no maintenance.
Gear for screen drum
The gear is supplied from the
factory with synthetic oil, ISO
VG 680. Check the oil level
in the gear on a regular ba-
sis. Change oil every 20.000
running hours, or latest after
4 years (at synthetic oil). At
mineral oil, the intervals will be
halved.
Oil type
See separate manual for the gear drive.
Never mix synthetic oil and mineral oil. If you want
to change oil type, it is necessary to clean the gear
very carefully.
Greasing of intermediate bearing on trough
auger
The intermediate bearing on the trough auger is
positioned in the bottom trough in the middle of the
cleaner.
The bearing construction is a steel shaft running in
a nylon bushing with facility for greasing.
Greasing of the bearing is extending lifetime of the
nylon bushing. It is beneficial to grease the bearing
each 40 hours of running. Preferable grease type
is: Mobiltemp SHC 460 Special, or similar grease
with content of graphite or/and MoS

Belt tensioning
Check at regular intervals that the belt is taut, espe-
cially while it is new. The first belt tensioning should
normally take place after 2 - 3 hours of operation.
Re tightening
In a new machine, all screws and bolts should be re
tightened after the first day of operation. Make sure
that they are always securely tightened.
Cleaning
Clean the machine if it is to stand idle for a consid-
erable period of time. Keep gear and motors free
from dirt, which may reduce the cooling.
