5.2 Hydraulic spool valve setup
The wrapper hydraulic valve must be set up in accordance with the type of hydraulic
system on the tractor, that is being used. Check the tractor manual or with your dealer
if you are unsure of which system is used on the tractor. If in any doubt after checking,
use open centre settings as this will not damage the tractors hydraulics.The valve may
be set up in two different ways:
1.
Plug A (manual, part no CVA06003) (electronic, part no CVA06004)
This plug is used for both
open centre
and
load sensing
hydraulic systems.
The hydraulic valve is set up to this specification when leaving the factory.
When using load sensing hydraulics, always reduce the tractor oil flow to under
30 l/min.
2.
Plug B (part no CVA06001)
This setting is used for
closed centre
hydraulic systems.

Changing from plug B to plug A (Manual & Electronic valves):
