Doosan Generator G90WJD-2A-T3 (C24)

Check for loose wire routing clamps. Clamps must be secure and properly mounted. Also check wiring for wear, deterioration and vibration abrasion.

Check for evidence of arcing around electrical terminals.

Check that the grounding circuit is in accordance with the National Electrical Code Article 250-122 and the local code requirements. As a minimum, the copper wire size should be American Wire Gauge 8 (AWG#8) from the grounding terminal, frame, generator and engine block.

Check for loose, or frayed wiring insulation or sleeving.

Check for water in the fuel filter/water separator unit. Some engines have a translucent bowl for visual indication, and others have a drain valve below the primary element.

Clean the air vents of any obstruction or debris.

Check Evidence of Arcing around electrical terminals.

Check Loose Wire Routing Clamps.

• Each month it is recommended that the intake hoses from the air cleaner and all flexible hoses used for water and fuel be inspected for the following:

1) All rubber hose joints and the screw type hose clamps must be tight and the hoses showing no signs of wear, abrasion or deterioration.

2) All flexible hoses must be free of wear, deterioration and vibration abrasion. Routing clamps must be secure and properly mounted.

2. Each month, inspect the radiator exterior for obstructions, dirt and debris. If present, blow water or compressed air containing a non-flammable solvent between the fins in a direction opposite the normal air flow. Should the radiator be clogged internally, reverse flushing, using a commercial product and the supplier’s recommended procedure, may correct the problem.

• On Keystart models, each month the diagnostic lamps should be tested. With unit shutdown and emergency stop pushed, turn the Engine Start Switch to “START”, or pull the ESTOP to apply power to the controller. All diagnostic lamps should glow; If not, refer to troubleshooting.

4. Diagnostic Trouble Code (DTC) Display

• On models with Electronic (ECU) engines, each month, the DTC display should be tested. When unit is started, the DTC Display should show dashes (---) or a trouble code if there is a fault condition.

• Weekly check the condition of the tires, and gauge the air pressure. Tires that have cuts or cracks or little tread should be repaired or replaced.

Check Engine Shutdown System Switches (setting)

Replenish with a fresh mixture every twelve months

Servicing or troubleshooting must be carried out strictly in accordance with instructions so as to avoid the risk of accidents and to maintain the machine in its original state.

All such operations performed on the alternator should be undertaken by personnel with training of electrical and mechanical components.

Before any intervention on the machine, ensure that it cannot be started by a manual or automatic system and that you have understood the operating principles of the system.

The bearings are greased for life: approximate life of the grease (depending on use) = 20,000 hours or 3 years.

Enter the temperature rise in the bearings

Temperature rise in the bearings does not exceed 60°C above the ambient temperature.

Should this value be exceeded, the machine must be stopped and checks carried out.
