Spring Adjustments
The springs locate to the hood via chains which allow for adjustment by resetting the chain length.
The chains length can be set longer by locating the spring into a longer chain loop to create a
heavier force to the ground where needed.
The machine ex-factory is set for light sweeping with one chain link spring connection. Once set this
does not normally need to be adjusted.

The settings can be
30-50mm.
The factory setting is
30-35mm.
By moving the spring support upwards to 50mm you can tension the springs to fine adjustment.
The initial factory setting is 30 - 35mm. Both sides on the pick-up hood should be adjusted in the
same way, although subject to road camber you might want to alter these settings to suit conditions.
Always try to set the pick-up hood to the lightest ground pressure.
