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 if there is no
hydraulic oil leakage in each part.
See the list in "Tightening torques" (Page
3-5) .
Note that the Baroness product warranty may
not apply to defects caused by incorrect or
overtorque tightening etc.
Check the amount of 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, apply
hydraulic oil onto the O ring and seal.
Fit hoses and hydraulic fittings only after
removing the cap and plug.
When fitting 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 circuit.

Make sure that there is no oil leakage.
In the event of leakage, stop the engine, set
the oil stopper, and check the amount of oil
in the hydraulic tank.
Add oil if necessary.
Hydraulic hose, piping
Warning
When checking for pinhole leakage of the
hydraulic circuit or oil leakage of the nozzle,
search for a leakage point using something
like paper or cardboard, never with your bare
hands. Be careful about high-pressure oil
which may pierce your skin, resulting in
physical injury.
Check the piping and hose every day for oil
leakage, damage to the circuit, looseness,
abrasion, loosening of connecting part, weather-
related deterioration and chemical-related
deterioration. If necessary, repair before
operating the machine.
Hydraulic Oil
Important
In the event of hydraulic circuit failure, be
sure to clean the circuit.
In the event of contamination or failure of the
hydraulic circuit, clean and/or replace the parts.
Since the hydraulic circuit is a closed circuit, any
contaminant will remain within the circuit and
may lead to other failures unless cleaned.
Caution
Be careful with hot oil, which could cause
burns if it contacts your skin.
Drive and maneuver the machine and warm
up the hydraulic oil.
Move the machine to level surface.
Apply the parking brake, and then lower the
operating machine.
