HYDRAULIC
GENERAL
• Raven Industries recommends that appropriate protective equipment be worn at all times when working on the
hydraulic system.
• Never attempt to open or work on a hydraulic system with the equipment running. Care should always be
taken when opening a system that has been previously pressurized.
• When disconnecting the hydraulic hoses or purging is required, be aware that the hydraulic fluid may be
extremely hot and under high pressure. Caution must be exercised.
• Any work performed on the hydraulic system must be done in accordance with the machine manufacturer’s
approved maintenance instructions.
• When installing RS1 HDU hydraulics or performing diagnostics, maintenance, or routine service, ensure that
precautions are taken to prevent any foreign material or contaminants from being introduced into the
machine’s hydraulic system. Objects or materials that are able to bypass the machine’s hydraulic filtration
system will reduce performance and possibly damage the steering hydraulic valve.
INSTRUCTIONS FOR HOSE ROUTING
The word “hose” is used to mean all flexible fluid carrying components. Follow existing hoses as much as possible
and use these guidelines:
Hoses should not contact or be attached to:
• Components with high vibration forces
• Components carrying hot fluids beyond component specifications
Avoid contact with any sharp edge or abrading surfaces such as, but not limited to:
• Sheared or flame cut edges
• Edges of machined surfaces
• Fastener threads or cap screw heads
• Ends of adjustable hose clamps
Routing should not allow hoses to:
• Hang below the unit
• Have the potential to become damaged due to exposure to the exterior environment. (i.e. tree limbs, debris,
attachments)
• Be placed in areas of or in contact with machine components which develop temperatures higher than the
temperature rating of hose components
• Hoses should be protected or shielded if it needs to route near hot temperatures beyond hose component
specifications
Hoses should not have sharp bends
