General Inspection and Repair
Note
Before Inspection and Repair
Move the machine to level surface.
Apply the parking brake, and then lower the
operating machine.
Stop the engine, and then remove the key.
Clean the machine.
Be sure to clean parts such as the piping,
hoses, and hydraulic fittings.
Remember that cleaning is always
necessary upon inspection and repair of
hydraulic systems.
Warning
Be sure to depressurize the hydraulic system
before inspecting or repairing it.
When piping and hoses are removed, put a
cap or plug in its place to prevent
contamination of the hydraulic systems.
Attach labels or other identifications to the
removed piping and hoses so that they can
be correctly refitted.
When removing piping and hoses, pay
special attention to the connection part.
If necessary, mark the piping and hoses to
ensure correct fitting.
After Inspection and Repair
Caution
After the installation, check that there is no
hydraulic oil leakage in each part.
Check the amount of hydraulic oil in the
hydraulic tank. Add as necessary.
In the event that failure or contamination is
found in the hydraulic circuit, replace the
hydraulic oil and filter.
When fitting hydraulic fittings with O rings,
apply hydraulic oil to the O ring.
Fit piping, hydraulic hoses, and hydraulic
fittings only after removing the cap and
plug.
When fitting piping, hydraulic hoses, and
hydraulic fittings, follow the proper
procedure for tightening.

After repair, check to see whether the
hydraulic system functions normally and
whether there are any broken parts.
When the hydraulic system has been
repaired or replaced, operate the machine
slowly, idling the engine, to allow the air to
go out of the hydraulic circuit.
Make sure that there is no oil leakage.
In the event of oil leakage, stop the engine,
repair the oil leak, and check the amount of
hydraulic oil in the hydraulic tank.
Add oil if necessary.
Towing
Important
Going over the limit of towing may lead to the
failure of hydraulic equipment.
Also, if the machine is towed at high speed,
the wheel may cease its motion.
Stop towing in case of wheel lock.
Resume towing at low speed after the
pressure has been stabilized.
In the event of loss of mobility due to engine
trouble or the like of, movement is possible
through towing or hand driving.
Take the shortest route when towing or hand
driving the machine.
Transport the machine on a trailer if you have
to transport it a long way.
For the towing method, see the owner's
operating manual of this machine.
Neutral
If the machine moves forward or backward
while the traveling pedals are released, they
are not set to the neutral position. Make
adjustments.
Depressurization
Be sure to depressurize the hydraulic system
with the steps below before inspecting or
repairing it.
Move the machine to level surface.
Apply the parking brake, and lower the
mower unit.
Stop the engine, and then remove the key.
Move the traveling pedal and all the drives of
the mower unit to the neutral position.
Turn the steering wheel to the left and right.
