MAINTENANCE
9.1 CHECKING FREQUENCY
The frequency of the checks indicated below is provided as a guideline. It may vary depending
on machine application and use, environment, temperature, weather conditions, etc.
- BEFORE STARTING THE SOWING SEASON:
Check the general operation of the planter. Perform this check without any seeds inside the
hopper.
Check that the plastic components of the planter are in good condition. The wear of this mate-
rial due to natural ageing or to the presence of rodents causes damages to these components.
Check that the mechanical components are in good condition and not rusty.
Clean the parts of the planter which are permanently in contact with seeds, such as hoppers and
metering boxes.
Check that the signal lamps work properly.
Check that the unions and the ducts of the hydraulic system do not show oil leaks.
- PERIODICALLY:
Before washing the planter with water, check that no seeds or fertilizer are inside the hoppers
or the metering boxes. After washing the machine, turn on the fan for some minutes in order to
remove the moisture from the metering units and the suction system.
Check that all the screws are in good condition, especially the ones which are in contact with the
ground. Tighten every single screw and bolt.
Check that the metering boxes and the suction system do not contain any residue (such as seed
or fertilizer residue, dust, etc). Residue accumulation may damage the suction system.
- END OF SOWING SEASON
Wash the planter well with a lot of water, making sure that no seeds, fertilizer or other products
remain inside the hoppers, metering boxes or ducts. Wash especially the parts of the planter
which are in contact with chemical products.
Properly lubricate the moving parts of the planter (see section 9.2 GREASING AND LUBRICA-
TION).
Repaint any metallic component which has lost its paint due to wear.
To store the planter properly, cover it with tarpaulin and keep it in a dry place.
Thoroughly check all components of the planter and replace the ones which are damaged or
worn.
KEEP THE SOWING EQUIPMENT CLEAN. THE ACCUMULATION OF EARTH, STONES, GRASS, ETC.
MAY BLOCK THE SOWING DUCTS.
