TROUBLESHOOTING
Front loader, implement and
implement with hydraulic function
is blocked during lifting or lowering
movement.
Coupling not completely closed. Check the hydraulic coupling.
The coupling is defective. Replace the defective coupling halves.
Hydro-Fix, multi-coupler and Implement-
Fix not fully closed.
Check the locking lever for deformation.
Check the couplings for firm seating, fasten
if necessary.
The front loader rocks when
lowering the load.
Lowering speed too high. Reduce the lowering speed.
Unstable implement on FS rapid
emptying front loaders (implement
tilts away backwards).
Rapid emptying activated without dumping.
This causes a vacuum in the hydraulic
system.
Only activate the rapid emptying during the
dumping process.
Increase the engine speed in order to
deliver enough oil.
The implement cylinder are
extended, but are not retracted
again.
Piston seal in the implement cylinder is
defective, so that the surface of the piston
and the ring are stuck together.
Check each cylinder separately for leaks
and if necessary replace any defective
cylinders.
Seat valve does not return to starting
position after turning on the rapid emptying.
Remove seat valve and check for debris, if
necessary, replace.
Insufficient oil flow. Check the tractor hydraulics.
The double pressure relief valve of the front
loader control block does not close.
Clean the double pressure relief valve and
replace if necessary.
Leaks on the hydraulic block and
system.
Loose bolted connections. Tighten the screw again.
Leak between the magnet and valve. Unscrew the knurled nut, remove the
magnet, tighten the magnetic core again
with an open-end spanner.
Leak between the valve flanges. Tighten the screws again or renew the
gasket rings.
Defective gaskets. Replace the gasket rings such as Walform.
The front loader is raised when
scooping from a lowered position.
Oil shortage on the piston rod side of the
lifting arm cylinder.
Increase the engine speed when lowering.
Lower without float position.
The front loader is raised when
scooping from a lowered position,
and when subsequently dumping,
the front loader is lowered very
fast.
Oil shortage on the piston crown side of the
lifting arm cylinder.
After the previous error, only actuate the
lifting function until the front loader is raised
and the implement can be carried in a
parallel position.
