TROUBLESHOOTING &
MAINTENANCE
Area
Problem
Remedy
Hydraulic
Oil supply under high
pressure immediately
the tractor hydraulic
lever is engaged.
- Hydraulic feed or return couplings not properly engaged.
- Hydraulic couplings connected to a double acting supply on the tractor and supply is in the wrong direction. This can cause the
poppet in the return coupling to lock closed. The coupling will have to be loosened to relive the locking pressure between the
check valve and the coupling.
Controller
Controller does not
power up.
- Check the switch on the back of the controller.
- Make sure the 3 pin power supply plug is securely connected.
- There are two 15A fuses on the power cable, check the condition of these.
Controller not counting
turntable revolutions
- Check the turntable sensor located on the tipping frame. This has an LED indicator that lights when the metal come within 5mm
of the tip.
- Check the controller communication cable is connected and not damaged.
Note if the table revolutions are not being counted many other automatic functions will not automate because they are triggered
by the count.
Film Cut
and Start
Cylinder only partially
extends.
- The oil pressure in the accumulator is over 60 Bar usually caused by leaking cylinder seals. Get this checked by a service engineer.
- Check operation of diverter valve on tipping frame.
Cylinder does not retract
to release the film
during wrapping.
- This cylinder is opened by the oil held under pressure in the accumulator. If the pressure is too low it will not open. Please get your
dealer to recharge the accumulator pressure.
- Check the wiring to the control valve.
Cut and start is closed
before film is gathered
The diverter valve on the tipping frame is activated too soon. Change the bolt to a lower hole in the link.
Bale is tipped off before
film is cut.
Diverter valve is activated too late. Move the bolt to a higher hole in the link.
Film is not cut cleanly
Check condition of blade.
Film
Dispenser
Film not wrapping even-
ly on to bale.
Adjust the film dispenser height so the centre of the film is in line with the centre of the bale.
Film breaking while
wrapping.
- Check for damage on the roll of film.
- Check for damage on the film dispenser rollers.
- Check film dispenser gears are rollers are rotating freely.
Wrapping
Drive roller and bale not
turning.
Check the shear bolt on the driver roller sprocket. If sheared replace with an M8 X30 grade 8.8 bolt.
