The Kobelco 140SRLC-3 Preface Instructions

Read and understand all Warning plates and decal on the machine before Operating, Maintaining or Repairing this machine. The Kobelco 140SRLC-3 Excavator 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 Shop 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 140SRLC-3  Excavator as a reference book and source of information even if you are familiar with Excavator technology. Using the Workshop Manual, the experience construction machine mechanic can carry out any necessary repairs expertly.

TROUBLESHOOTING

(1) If an abnormal condition is noticed, check to see if the problem is with the control valve itself, one of the main
pumps, the gear pump, or a circuit. To this end, you will need to measure pilot pressure, pump delivery
pressure, load pressure, etc. If any part of the system is to be disassembled for inspection, follow the
disassembly and reassembly procedures in this manual.
(2) Dust is the enemy of hydraulic components. Pay strict attention to protection from dust. If any part of the system
is to be disassembled, take dust protection measures beforehand.
(3)Moving parts must be handled with care. If they are damaged, smooth the damage using an oil stone or the like.
(4) Take care not to damage the contact face of O-rings. A damaged contact face will certainly cause oil leaks.
