TROUBLESHOOTING
Following table shows the most common problems and the solutions to them. There are more instructions
and troubleshooting advice concerning the engines in the Owner’s Manual of the engine (Honda or Kubota).
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
(lever no. 3, page 12) is in locking
position.
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
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.
