12.1 Safety Precautions before Working on Hydraulic
System
WARNING
High Hydraulic Oil Pressure
Working on the hydraulic system involves a high risk of personal injury.
u Make sure that the system is de-pressurized before starting any work.
WARNING
Hydraulic Oil and Water Pressure
Can cause personal injury.
u Do not replace high-pressure hoses with hoses of lower quality than the originals.
u Do not replace high-pressure hoses with hoses installed with removable couplings.
12.2 About Working on Hydraulic Components
The hydraulic system is sensitive to contamination. The environment where the machine is
normally used is generally an unsuitable place for repairing hydraulic components. Avoid
repairing hydraulic systems outside workshops.
Observe the following points to minimize interruptions in operation due to contaminated hy-
draulic oil:
• Keep the machine clean.
• Use a degreasing additive for washing.
• Before opening any hydraulic connection, clean the area round it.
• Use clean tools and work with clean hands.
• Always plug hydraulic connections immediately after they are disengaged.
• Use clean protective plugs.
• Hydraulic components, like hoses, valves, and motors, must always be stored with
suitable protective plugs are installed.
• Spare parts for hydraulic components must always be kept in sealed plastic bags.
• Change filter cartridges when filters indicate clogging.
12.3 Hydraulic Workshops
Workshops that are used for the repair of hydraulic components must include:
• A clean environment to avoid dust and particles
• Suitable washing equipment for component repair
• Suitable tools for working on hydraulic systems
