HYDRAULIC CONNECTION. (See Fig. 13-1)
The
1300S
machine uses two of the tractors remote valves to operate. One valve operates the
wrap arm rotation and cutter, the second valve operates the rollers in (loading) and rollers out
(unloading) function.
There are 4 no. hydraulic connections between the 1300S machine and the tractor. They are
divided into two pairs, one pair connected to one side of the entry block (marked ‘P’ and ‘T’ on
the side of the block) and the second pair connected to the opposite side of the block (marked
‘R+ and ‘R-‘).
The hose from P can be connected to either a single or double acting service on the tractor, this
is the hydraulic supply for wrap arm rotation and cutter.
The hose from T (fitted with a female Q/R coupling) must be connected to a free return to
tank
. This is the return from the wrap arm rotation and cutter. The Cutter will not operate
correctly if this is not a free return.
Hoses from R+ and R- should be connected to a double acting service on the tractor. This is the
hydraulic supply for rollers in and rollers out.
The
1300 SM
is equipped with a two bank, cable operated valve. This requires just two
connections, a Feed and return. If possible arrange for a free return for the Return line as this
eliminates the risk of
Hydraulic lock
. This occurs if you try to send oil in the opposite direction
against the non-return valve. This results in pressurized oil between the non-return valve and the
quick coupling and prevents connection of the quick coupling. The only way to discharge the
pressure is to open the quick coupling using two 27 mm spanners.
The hydraulic hoses between machine and tractor are equipped with 3 no. 1/2" ISO male quick-
couplers and 1 no. female coupler. Discharge the oil pressure before you connect the oil hoses.
Use the tractors' hydraulic lever.
To make sure that the bale wrapper works properly, the tractors' oil pressure has to be at least
180 bar. The oil flow should be 25 - 40 liters per minute.
4.9 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.
Tie up loose hoses so that no squeeze damages occur.
3.
Remove the locking bolt that holds the wrapping arm to the frame during transport.
4.
Start the tractor and try out the functions, pull and hold the tractors single acting hydraulic
lever (note you must press the ‘Reset’ button on the controller for the wrap arm to
operate), the Cutter should automatically open and close on the second turn and also on
the last set turn the wrap arm will go into slow speed and the cutter will open, when you
hear the controller bleep release the hydraulic lever, the arm rotation will stop and the
cutter will close.
Check the operation of the roller arms out and in on the second service.
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 open properly for the oil flow.
