GB 3.3 Extraordinary maintenance

For some maintenance operations there is the possibility of pulling the generator out by sliding the entire bottom of the generator on the guides fixed to the sidewalls of the casing. To set the gene- rator basis free loosen the harness and unscrew the 4 fastening screws. The generator unit will be extractable by ¾ of its depth. To come to a complete extraction put the generator basis on firm ground to protect it against possible falls and unscrew the 2 limit stop screws. Alternatively tighten the generator basis inserting screws in inner position.

Changing the oil

Warning

Hot oil can burn your skin!

Check the oil level with the engine turned off.

Important

Old oil moust not be disposed of in the environment, but left to a station specialised in the disposal and/or recycling of the same, respecting the laws in the country where the operations are carried out.

Use oil recommended for 4-stroke Diesel engines of these types: CCMC-D4-D5-PD2or API-CD-CE-CF-CGor SHPD (this indication is

on the oil can).

SAE 10W-30 oil is recommended for general use at all temperatures. If you use monograde oil, choose the appropriate viscosity on the basis of the average temperature of the place where the generator is installed.

To drain the old oil easier you should run the generator for roughly 3/5 minutes, in this way the oil is more fluid and will drain better through the drain tube when you remove the drain plug. Refill the generator with oil of the recommended type, through the oil filler.
