Service and maintenance:
Bearings
All motor bearings are lubricated for life from the fac-
tory, and requires no maintenance.
Gear for screen drum
The oil level should be checked regularly and filled if
necessary. Also check the gear for leakages, and the
condition of the oil seals. Replace any leaking seals.
Oil is filled through the (top) vent screw hole, checked
through the middle screw hole (located just above the
motor) and drained through the bottom screw hole.
The gear is filled with synthetic oil, ISO VG 680, for
operation in working areas -20 to +40 ° C.
The gear oil is first replaced after 300 hours of opera -
tion, and then every 2 years or after 10,000 hours of
operation with mineral oil. For synthetic oil, the interval
is every 4 years or every 20,000 operating hours re-
spectively.
See any separate manual for the gear drive.
Recommended synthetic VG 680 oil types are:
Mobil Glygoil 680 or Shell Omala S4 WE 680.
The gear unit ventilates through the vent screw at tem-
perature fluctuations.
The gear motor must be cleaned as needed so that
cooling does not decrease.
Gear for auger
The gear units on the gear motors are filled with syn -
thetic oil from the factory, which does not require re-
placement. Pay attention to leaky oil seals, and replace
if necessary.
Oil type
See any 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.
Gas dampers on side doors
The dampers must be inspected and replaced as
needed.
Greasing of intermediate bearing on trough auger /
screen drum main bearings
The intermediate bearing on the trough auger is posi-
tioned 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

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.
Electrical connection and cable connections
Check the electrical connection in the control cabinet
- the cable glands must be tight and there must be no
loose conductors. Also, check the various cables regu-
larly. Additionally, check the magnetic contacts on the
side doors for proper attachment and function.
Cleaning
Clean the machine if it is left unused for a considerable
period of time. Keep gear and motors free from dirt,
which may reduce the cooling. The inspection windows
can be removed and wiped off when necessary. The
window is removed by turning the thumbscrew 90° and
tilting the frame outwards.
Storage
If the cleaner is used for outdoor installation, and will
be out of use for a longer period, it is recommended to
open the outlets from the auger to avoid water being
collected in the bottom of the machine.
