• Daily 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.

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.

Monitor the temperature rise in the bearings

Temperature rise in the bearings not exceeding 60°C above the ambient temperature

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