• 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.

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.

• 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).

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.;

Ensure all electric loads are disconnected, engine is stopped and main breaker is turned on.
