General maintenance
Figure 5.5
A machine is only as good as the service it receives!
Before starting work, check that all nuts and screws are tightened. During the season, check the
tightness of nuts and screws regularly, as well as the wear on linkages and the hydraulic ram
mountings.
NOTE!
The screws holding links should not be tightened so much that movement in the linkage is
restricted.
The hydraulic system does not normally require any maintenance, but check that the hoses and
couplings are undamaged.
NOTE!
Dirt must be kept out of the hydraulic system during any service work. Wipe with clean
paper or a clean rag. Lay the parts on a clean surface (not directly on the work bench). Rinse off
parts with e.g. a degreasing compound before fitting them.
Always grease the piston rods after cleaning them or if the drill is not going to be used for a long
time.
Grease galvanized and chromium plated surfaces before long periods of storage.
To maintain the quality of this seed drill, always use Väderstad original spare
parts.
5.2
Seed feed housings and rape brushes
The inside of the seed feed housing must be cleaned out regularly and frequent checks must be
made for signs of wear on plastic and rubber components. It is specially important to ensure that
seed additive deposits do not build up in the scoops, reducing their volume.
The casing with the scale can be drained from below and can be rinsed through once the feed hous-
ing has been turned down nearly to zero.
Clean inside the transparent transmission cover when necessary.
Check that the blades of the cellwheel do not jam but that they bear against the bottom of the
groove during setting from zero and upwards.
Check the wiring.
Rape brushes
Before setting the drill for rapeseed, always check the rape brushes
and clean them if necessary.
Check that the brushes spin easily on their axles. The rape brushes must never be greased.
