Problem
Possible cause
Remedy
DPF regeneration does not
start
DPF regeneration is inhibited
manually
Check DPF settings on display
Engine coolant temperature is
low
Engine load might not be high enough to keep engine coolant
temperature above required minimum for DPF. Increase engine
load.
Engine coolant may be too low for DPF regeneration due to
faulty thermostat. Check operation of thermostat, contact
service.
Engine overheats
Clogged radiator
Clean radiator and fan from engine side.
Dirt around engine
Clean engine and its surroundings carefully
Coolant level low
Add coolant.
Leaking cooling system
Check coolant pressure reservoir cap for tightness. Check
cooling system and all hoses and connections.
Hydraulic attachment does
not work when the auxiliary
hydraulics control lever is
moved
Attachment hoses are not
coupled or the multi connector
is not fully locked.
Make sure that the multi connector is properly connected.
Faulty or damaged quick
couplers (will restrict or stop oil
flow)
Replace quick couplers in multi connector.
Operator not seated on driver's
seat
Operator must sit on driver's seat to activate auxiliary
hydraulics. Also, other operating mode can be selected to
operate certain attachments from another control position, see
page 56.
Fault in attachment
Check with another attachment, if possible.
