Why does the front furrow width change during work with my LEMKEN VariOpal Farm Equipment?
If the front furrow width of your LEMKEN Farm Equipment changes during work, it is likely that the piston seal of the swing-in ram or Memory ram is leaky. The suggested solution is to replace the piston seal.
What to do if the plough frame turns but the turnover ram switches over too early on my LEMKEN VariOpal?
If the plough frame turns, but the turnover ram switches over before reaching the half-turned position causing the plough frame to turn back again on your LEMKEN Farm Equipment, it could be due to several reasons: * The pre-adjusted switchover pressure is too low. Increase it by fitting additional washers (U); one washer equals a 10 bar increase. * The inner turn-buckle is too long. Shorten the inner turn-buckle. * The bearing of the turnover device is damaged. Check the bearings and replace if required.
Why does the plough frame stop at the middle position on my LEMKEN VariOpal Farm Equipment?
If the plough frame on your LEMKEN Farm Equipment turns up to the middle position and stops, it indicates that the required switch-over pressure for the turnover ram has not been reached by the tractor hydraulics. You can try: a) Reducing the pre-adjusted switch-over pressure by removing the washers (U). Removing one disc means a pressure reduction of approximately 10 bar. The washers (U) are located behind the plug (V). b) Checking and maintaining the hydraulic assembly of the tractor, if required.
What to do if the turnover ram switches over without turning the plough frame on my LEMKEN VariOpal Farm Equipment?
If the turnover ram switches over without turning the plough frame on your LEMKEN Farm Equipment, it could be due to: a) The pre-adjusted turnover pressure being too low. Increase the pre-adjusted switchover pressure by adding an additional washer (U). b) The cone or its seat of the switch-over valve being damaged and leaky. Replace the hydraulic ram.
How to fix a Memory ram that won't open or close on LEMKEN VariOpal?
If the Memory ram on your LEMKEN Farm Equipment does not open or close, it is possible that the throttle bores of the threaded throttle in the Memory ram are blocked. To resolve this, screw out the threaded throttles from the ram connections using a circlip tong and clean them. Note that Connection (S) has no throttle.
Why does the plough frame start turning before the Memory ram is fully swung in on LEMKEN VariOpal?
If the plough frame on your LEMKEN Farm Equipment starts turning before the Memory ram is fully swung in, it indicates that the friction of the frame pivot bolts is too high. Grease the pivot bolts carefully, following the maintenance table.
