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.
(implement tips to the rear)
The load tips over too fast due to heavy
load. This causes a vacuum in the
hydraulic system.
Increase the engine speed in order to
deliver enough oil. With the implement in
dumping position, continue "actuating the
dumping function" until the cylinder is filled
with oil again.
Unstable front loader.
(The front loader deflects up or
down when pushing)
The front loader was lowered too fast by
gravity.
This causes a vacuum in the hydraulic
system.
Increase the engine speed in order to
deliver enough oil. With the implement
lowered, continue "actuating the lowering
function" until the cylinders are filled with oil
again.
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.
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.
