TESTING AND TROUBLESHOOTING
The troubleshooting sections help identify the causes of mechanical, hydraulic and electrical faults. Diagnostic procedures guide the technician through a logical sequence of inspections and tests before components are dismantled or replaced.
Testing and adjustment information includes inspection methods, standard measurements, operating values and adjustment procedures. These allow actual machine performance to be compared with the correct service specifications and help technicians locate problems accurately.
This information is particularly useful when investigating difficult starting, loss of engine power, overheating, slow hydraulic operation, reduced digging performance, abnormal attachment movement, travel problems, swing faults, warning indications or electrical malfunctions.
HYDRAULIC SYSTEM INFORMATION
The hydraulic sections explain the operation of the pumps, control valves, cylinders, motors and associated circuits. Procedures cover hydraulic inspection, pressure testing, adjustment, component removal, dismantling, repair and reassembly.
Understanding the hydraulic circuits helps technicians diagnose slow operation, reduced hydraulic power, leakage and incorrect boom, arm or bucket movement. Following the correct testing procedures can also prevent serviceable components from being replaced unnecessarily.
ENGINE AND ELECTRICAL SYSTEMS
Engine information covers the inspection, testing and servicing procedures needed to maintain reliable machine operation. The manual also contains technical guidance for the fuel, cooling, intake and lubrication systems.
Electrical information assists with diagnosing starting, charging, monitoring and control problems. Wiring information, component locations and testing procedures help identify faulty circuits, poor connections, switches, sensors and other electrical components.
TRAVEL, SWING AND UNDERCARRIAGE
The manual provides technical information covering the travel motors, final drives, swing machinery, tracks and associated undercarriage components. Inspection and repair procedures help identify wear, damage and incorrect adjustment before more serious problems develop.
Work-equipment information covers the principal components used to operate the boom, arm and bucket. Hydraulic and mechanical procedures assist with diagnosing reduced performance, unusual movement and excessive component wear.
DISASSEMBLY AND ASSEMBLY
Step-by-step repair procedures explain the correct sequence for removing, dismantling, inspecting, assembling and installing components. Instructions include important measurements, inspection points, service limits and adjustment requirements where applicable.
Detailed illustrations, sectional drawings and exploded views help identify individual parts and show their correct positions during reassembly. This is particularly valuable when carrying out major engine, hydraulic, travel, swing or undercarriage repairs.
