Doosan Generator G80

• 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).

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 current hours of operation

Is the current hours of operation less than 20000 hours?

Monitor the temperature rise in the bearings, which should not exceed 60°C above the ambient temperature.
