Preface Instructions

Read and understand all Warning plates and decal on the machine before Operating, Maintaining or Repairing this machine. The manual has been written for the repair specialist. The serviceman or mechanic may be unfamiliar with many of the systems on this machine. This makes it important to use this manual and be caution when performing service work.

Please go carefully through the manual of the excavator before starting any repair work. Use proper lifting procedures when removing any components. Be careful when removing filler caps, breathers and plugs on the machine. Hold a rag over the cap or plug to prevent being sprayed or splashed by liquids under pressure. The danger is even greater if the machine has just been stopped because fluids can be hot.

Use the Shop/Service Manual of the SK75UR-3E, SK130UR-3E as a reference book and source of information even if you are familiar with Excavator technology. Using the Repair Manual, the experience construction machine mechanic can carry out any necessary repairs expertly.
