Problem

Possible cause

Remedy

Attachment hoses will not go
into the extra front or rear
quick couplers of the loader

There is back pressure in the
auxiliary hydraulics line.

Release the pressure by moving the extra auxiliary hydraulics
control lever in both directions.

Hydraulic system overheats

Hydraulic oil level low

Check and refill, see page 112.

Clogged oil cooler

Clean cooler and fan

Fan faulty

Check and clean, repair if necessary

Hydraulic oil flow restricted

Make sure auxiliary hydraulics valve is completely opened
when using high flow attachments. Adjust lever locking plate if
necessary.

Hydraulic system overloaded

Use attachment at lower engine rpm, use with 1-pump setting,
check attachment for faults.

The loader does not move
even after the parking brake
has been released.

Bad connection on the wiring of
the parking brake switch, blown
fuse, or faulty switch

Check wires, fuse, and switch, repair if necessary. Contact
service.

Low hydraulic charge pressure

Contact service for pressure check.

Faulty solenoid valve

Check and replace if possible. Contact service
