Doosan Generator G10WMI-2D-T2 (B63)

• Every six months or 500 hours, or less if fuel is of poor quality or contaminated, replace the bowl elements(s).

• The engine coolant system is normally filled with a 50/50 mixture of water and ethylene glycol.

• This permanent type anti-freeze contains rust inhibitors and provides protection to -35°F (-37°C). The use of such a mixture is recommended for both summer and winter operation.

• When using water alone, be sure to add a reputable brand of rust inhibitor to prevent internal corrosion.

• It is recommended to test the freezing protection of the coolant every six months or prior to freezing temperatures. Replenish with a fresh mixture every twelve months.

3. Check Control Compartment (Interior).

Proper maintenance of the air cleaner provides maximum protection against airborne dust.

Squeeze the rubber valve (precleaner dirt dump periodically to ensure that it is not clogged).

To service the air cleaners, proceed as follows:

Inspect air cleaner housing for any condition that might cause a leak and correct as necessary.

Wipe inside of air cleaner housing with a clean, damp cloth to remove any dirt accumulation. This will permit better seal for gasket on filter element.

The air cleaner assembly (housing) should be inspected every 3 months or 500 hours for any leakage paths.

Make sure the inlet is free from obstruction.

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

Check daily for evidence of arcing around electrical terminals.

Daily 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.

Daily check for loose, or frayed wiring insulation or sleeving.

Daily 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.

Daily clean the air vents of any obstruction or debris.

Check Evidence of Arcing around electrical terminals.

Check Loose Wire Routing Clamps.

Check Engine Shutdown System Switches (setting)

Replenish with a fresh mixture every twelve months

1. Voltage Selector Door Interlock Switch

• Every three months or 250 operating hours, the interlock switch should be checked. Running with no electric load, open the VOLTAGE SELECTOR door. This will shutdown the engine and trip the main breaker. To reset, close the door.

2. High Containment Fluid Alarm System

• The operation of the high containment fluid alarm system should be checked every 3 months or whenever it appears not to be operating properly.

• The level switch is located at the lower end of a pipe at the bottom of the containment tank.

• Test the switch by unfastening the u-bolts holding the pipe, and then inverting the pipe to allow the switch float to fall.

• The “High Containment Level” LED should illuminate. Replace any defective switch.

• Drain the containment area using the drain plug at either end of the containment basin.;
