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.
Stop the engine, and then remove the key.
Warning
Be sure to depressurize the hydraulic system
before inspecting or repairing it.
Important
Be sure to clean the circuit connecting part to
be repaired.
Drain the oil from the hydraulic tank.

Drain the oil from the hydraulic hoses and
piping while the oil is still warm.
Check the hydraulic tank and suction filter,
and clean.
Fit the hydraulic hoses, piping and hydraulic
fittings that have been removed.
Caution
Use only the specified hydraulic oil.
Use of other hydraulic oil may lead to the
failure of hydraulic circuit or the like.
Replace the hydraulic oil and filter.
Make sure that the traveling pedal and all the
drives of the operating machine are in
neutral position.
Start and run the engine for 10 seconds to
check that there is no oil leakage or else.
Perform this operation twice.
Start the engine.
Let it run idle for at least two minutes, then
run at the maximum speed for one minute.
Raise and lower the operating machine.
Stop the engine, and check for any oil
leakage.
Check the amount of hydraulic oil. Add as
necessary.
Operate for two hours under normal
operating conditions.
Check the condition of hydraulic oil.
If it is contaminated, repeat the procedures
from 1 through 15 until the oil becomes
clean.
If no abnormality is found, operate normally
and maintain according to the maintenance
schedule.
