Preparing for operation
55
> Loosen the hexagon socket screw on the seed row
> Slide the sprocket and seed row alternately in small increments as
desired. Ensure correct chain alignment whilst doing so.
> Resecure the sprocket and seed row
Points to note when positioning the outer seed row fully out-
wards:
In addition to the steps described above, the following must be adju-
sted:
•
Overpressure hose
•
Sprocket
> Before adjustment, loosen the screw on the overpressure hose
and remove the hose
> Following adjustment, refit the overpressure hose on the outer side
You can remove the outer sprocket and turn it 180°. It is easier to
achieve the correct alignment of the seed row and sprocket if the seed
row is positioned fully outwards.
> Slacken the chain
> Loosen the grub screw on the sprocket
> Remove the sprocket and turn it through 180°
> Slide on the sprocket and secure with the grub screw
> Pull on the chain
