5.1.9 Hydraulic System Maintenance
Hydraulic equipment is at a high temperature during operations and immediately after operations. During
operation, it‘s also under high pressure, so be careful of the following points when carrying out inspection
and maintenance of hydraulic related equipment.
Stop the machine on level ground, lower the bucket completely to the ground.
Always stop the engine and release pressure in hydraulic piping.
Immediately after the engine is stopped, the hydraulic oil and lubricants are at a high temperature and
high pressure. Wait for the temperature to go down before starting the maintenance operation.
Even when the temperature goes down, the circuits may be under internal pressure, so when loosening
plugs, screws, or hose connections, do not stand directly in front. Loosen gradually to release the
internal pressure before removing.
Always release the air in the hydraulic tank to remove the internal pressure before carrying out
inspection and maintenance of the hydraulic circuit.
Inspection and maintenance works include checking the hydraulic system for oil level, replacement of
filter elements and replacement of hydraulic oil.
If high pressure hoses have to be removed, check that there is no damage to the O-rings. If any
damage is found, replace the O-ring.
