TROUBLESHOOTING
Problem
Hydraulic attachment does not
work when the auxiliary
hydraulics control lever is
moved.
Engine does not start.
Attachment hoses will not go
into the quick couplers of the
machine.
The machine moves after
parking brake has been engaged.
Cause
Attachment hoses are not
coupled or they are coupled
wrongly in the quick couplers.
Faulty or damaged quick couplers
(will restrict or stop oil flow)
No fuel.
Auxiliary hydraulics control lever
is in locking position.
Blown fuse no. 3 (fuses in the
fuse box are numbered).
Battery empty or damaged.
If the starter motor works but
there comes no smoke from the
exhaust when one tries to start,
the engine is not getting fuel.
There is back pressure in the
auxiliary hydraulics line.
The pins of the parking brake
mechanism have not locked
properly in the wheels.
Remedy
Make sure that the hoses are
properly connected into the
quick couplers, change the place
of the hoses if necessary.
Auxiliary hydraulics have
double acting pressure couplers
(female) and a return line (male
coupler) Operating direction
of the attachment depends on
how the hoses are connected
in the quick couplers.
Replace quick couplers.
Fill the tank and start the engine.
Diesel engines have automatic
fuel bleeding  just glow and
restart.
Turn the lever in center
(neutral) position.
Change the fuse.
Jump start with another battery,
then charge the battery, or
replace if damaged.
Make sure that the fuel hoses
and fuel filter are clean and not
frozen. Clean if necessary.
Release the pressure by moving
the auxiliary hydraulics control
lever in both directions.
Drive slowly forward or
backward in order to lock the
parking brake.When releasing
the parking brake do this in
opposite order.
