1. Pomi Stack 200
Thank you for choosing the Stack 200 bale stacker from POMI for your straw and silage
needs.
Using the bale stacker for any other purposes is subject to prior written permission from the
manufacturer.
2. Safety instructions
FOR YOUR OWN SAFETY
Only carry out work on the machine when the tractor has been stopped and the
emergency stop on the electric box has been activated.
Do not allow unauthorized personnel within a distance of 10 m from the machine
when it is in operation as the machine can make sudden movements and oil may
squirt from a damaged hose.
The lights must be functioning in accordance with national traffic regulations. It
is the operator’s responsibility to ensure that the lights meet current national
legislation.
Drive sensibly when using the bale stacker, as reckless driving will damage the
trailer. POMI assumes no liability for any damage caused.
Special care should be taken when setting the oil flow speed, as too much oil may
cause the tractor to overheat and consequently damage the tractor. POMI
assumes no liability for any such damage.
Remember to re-tighten the wheel and the wheel axle

7. Bale stacker start-up
Use the start button to start and pause the loading
program. Press this button to start automatic
loading. The external button ( 1 ) has the same
function.
Use the Menu to choose between the two loading
programs. Choose the loading program where the
bale clamp starts in the inner position or the other
program where the bale clamp starts in the outer
position. By pressing the start button when the bale
clamp is in the inner position, the bale clamp comes
out. You use this for turning the bale. When
pressing the start button a second time, the
loading program will start.
By pressing Menu, you can switch the program so
the bale clamp starts in the outer position. Press the
start button to start the loading program.
When the loading program starts, the bale clamp
compresses the bale until reaching the compression
pressure set in the PLC. The bale is then lifted
upwards until sensor B2 is activated.
In this position the bale clamp releases the bale
when the set pressure is reached. The fork yoke then
moves downwards until sensor B3 is activated, and
the trailer is ready to receive the next bale.

When the loading platform is full, it tilts
upwards until sensor B4 is activated. It is then
lowered until it reaches sensor B5. When the
loading platform stops in the top position, the
trailer is full. It is therefore important to enter in
the PLC how many layers and stacks you want
to load onto the trailer. See the section on the
electric box.
The push-off mechanism cannot be used, if the trailer is not tipped upwards and sensor B8 is
activated.
The push-off mechanism must be pulled in and sensor B6 must be activated before the trailer
can be tilted up or down.

8. The hydraulic system
8.1. The trailer valve block
Use the hex screw ( 1 ) to adjust the oil flow when using a load sensing control system (LS).
The pressure control valve ( 2 ) is set to 180 bars.
8.2. Valves in the control box/toolbox
When using an LS control system, the hex screw ( 3 ) must tightened and when not using an
LS control system (hydraulic circulation) it must be loosened.

9. Electric box
In the PLC on the electric box you set how many
layers and stacks you want to load onto the trailer.
Here you also set the closing and opening time for
the bale clamp.
If you need to change any of the values, press and
hold the ESC button until a row lights up.

14
Then, using the up and down arrows, move to the
row you want to change and press OK.
Then there is only one number marked where you
can move the selection with the left/right arrows,
and change the value with the up/down arrows.
Press OK, and exit by pressing the ESC-button.
