- The cleaning capacity will change when adjusting the rotating speed and the inclination
angle of the drums.
- A moderate throughput of seed grain will lead to a better end result.
- For commercial purposes, the capacity can be set to the maximum.
- For a more precise screening of larger quantities, it is recommended that a 6 mm internal
drum is used for wheat and rye.
- The 4 x 15 internal drum is suitable for all grains, but when using oats, its capacity will
only be 150-200kg/h.
8. Maintenance
When necessary, the machine can be cleaned using a brush and a vacuum, particularly if a lot of
loose rubbish has accumulated into the recess at the power end. The discharge hatch at the edge
of the conical part must be opened. The drums are brushed with a coarse brush, in the direction
of the holes. The threads of the height adjustment screw can be lubricated when necessary. Keep
the grain grader and the drums protected from rain and sunlight, in an undercover area. Store the
drums in a vertical position.
Check annually:
- the condition of the drive wheels of the feed end
- check the rotation of the feed roller by lifting the lever
- ensure that the bearings are in good condition
Check Motovario's valid instructions before use. The maintenance instructions for Motovario's
variator and worm gear reducer, in brief:

check regularly that the external surface of the motor and the variator is clean;
particularly such surfaces that affect cooling.

Check regularly that there are no oil leaks in the equipment; particularly the shaft seals
and the O-rings.

The switch has been lubricated permanently, it does not have oil change plugs. You do
not need to change the oil of the switch.

For the variator, the oil change interval is 5000h. When the machine is used for sorting,
oil change is usually not necessary, due to the small amount of operating hours.

You can check the variator's oil amount visually (C). Oil is added through the plug (B).
When adding or changing oil, the motor package must be removed from the drawing
head.

The normal operating temperature of the variator and the switch is (-5°C - +40°C). The
lowest recommended operating temperature is -15°C. Please ensure that the machine has
sufficient cooling air when using the machine in hot weather.
