OPEN AND CLOSED CENTER HYDRAULIC SYSTEM.
With the valves you can choose between a hydraulic system with open or closed centers. Almost
all tractors have a hydraulic pump that gives a fixed oil flow per revolution. (Open center). TANCO
AUTOWRAP 1300 is set-up in the open position on leaving the factory. Some tractors, (like John
Deere), have an oil pump with variable volume per revolution. (Closed center). If you intend fitting
this machine to a machine with a closed center system a special closed center kit is required. See
spare parts list.
The contents of V6 must be replaced with pos. 13 and V7 with pos. 15 in the spare parts list.

CHECK LIST.
Before using the machine it is recommended to follow this check list:
1.
Make it a habit to discharge the oil-pressure before connection or disconnection of the
hydraulic hoses. (By operating the hydraulic control lever inside the tractor). (Use the
tractors hydraulic control lever).
2.
Return-oil should be led directly to tank. Beware that if the counter pressure is too high, the
security valve on the main block will release some oil. (See chapter 13).
3.
Hose with
BLUE CAP = RETURN OIL.
4.
Hose with
RED CAP = PRESSURE.
5.
Tie up loose hoses and Connection Cables so that no squeeze damages occur.
6.
Remove the locking bolt that holds the wrapping arm to the frame during transport.
7.
Start the tractor and try out the functions. A bale is not required for this test.
8.
Check all connections, hoses and couplings. If there is any oil-leakage, it should be
rectified immediately.
If any problems should occur, it is most likely that the failure is in the quick-couplers on the
tractors pressure and return-connections.
Make sure that both the male and the female-couplers opens properly for the oil flow.
Check them carefully. The best thing to do is to exchange the quick-coupling on the return side and
arrange a
"free return".
Your TANCO AUTOWRAP bale wrapper has been tested in practical operation in approx. 2 hours
at the factory.
