Do not perform any procedure in this Special Instruction until you have read the information and you understand the information.Safety Section
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat® products.Dispose of all fluids according to local regulations and mandates.
Personal injury can result from hydraulic oil pressure and hot oil.Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system.Make sure all of the work tools have been lowered to the ground, and the oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand.
Personal injury or death can result from improperly checking for a leak.Always use a board or cardboard when checking for a leak. Escaping air or fluid under pressure, even a pin-hole size leak, can penetrate body tissue causing serious injury, and possible death.If fluid is injected into your skin, it must be treated immediately by a doctor familiar with this type of injury.

This inspection form is intended to assist with identification and prioritization of failure modes associated with hose assemblies and to increase your ability to identify and proactively resolve issues in order to minimize fluid loss, machine downtime and avoid environmental impact.Various site conditions, the environment and machine age should always be considered when inspecting hose assemblies.When performing a machine walk-around, always follow local safety guidelines and wear the appropriate PPE. Prior to inspection, turn off equipment power and release pressure from the accumulators along with the system pressure. Make sure equipment is in a safe or neutral position, retract all cylinders, drop the load, and allow enough time for cool down. Chock tires as necessary. NEVER touch a hydraulic hose that is under pressure.Replacement Indicator Levels
When inspecting hose assemblies, the recommended Replacement Indicator Levels noted below should be considered. For detail and replacement recommendations, please reference the following pages.Replacement indicator 1
Hose assembly is visibly damaged and risk of failure is high.Replacement indicator 2
Hose assembly is showing early signs of fatigue or wear and risk of failure is low.Note: Where possible take photos to highlight areas of concern and attach to report.Replacement Indicator 1 (Major Risk)
Hose is visibly damaged and may consist of
