Repairing And Replacing Seed Hoses; Replacing The Fan Revolution Sensor - Vaderstad RAPID RDA 400 S Instructions Manual

4.15 Repairing and replacing seed hoses

Figure 4.24
Repair
If a seed hose is worn or bent, it can be patched with a joint, Part No. 415397 for Ø32 mm hose.
This dimension refers to the internal diameter of the hose and the external diameter of the joint.
Cut the hose in the centre of the damaged area. If necessary, a small section of the damaged area
may be cut off. It the hose is too stiff with the joint and cannot be bent sufficiently when the drill
is folded, it may be necessary to replace the entire hose, or to move part of the hose and join it in
two places.
Replacing seed hoses
Use soapy water on the hoses when removing and refitting. Twist the hose anticlockwise during
removal and replacement so that the spiral reinforcement opens up the hose slightly. Cut the spare
hose to the same length as the old hose.
Order new wearing parts in good time before the season!
Good maintenance means good economy!
