A maximum aromatic content of 35 volume percent.

2.Beginning October 1, 2010, owners and operators that use diesel fuel must use diesel fuel that meets:

A.Sulfur content of 15 parts per million (ppm) maximum.

B.Cetane index or aromatic content as follows:

A minimum cetane index of 40 or;

A maximum aromatic content of 35 volume percent.

General Information

Before installing and connecting the battery, complete the follow- ing steps:

1.Set the generator'sAUTO/OFF/MANUAL switch to OFF.

2.Turn off utility power supply to the transfer switch.

3.Remove the 10A and 15A fuses from the generator control panel.

Battery cables were factory connected at the generator (Figure

4.Connect the red battery cable (from starter contactor) to the battery post indicated by a positive, pas or (+).

5.Connect the black battery cable (from frame ground) to the battery post indicated by anegative, NEG or (-).

NOTE:

Damage will result if battery connections are made in reverse.

NOTE:

The generator is equipped with a battery trickle charger that is active when the unit is set up for automatic operation. With the battery installed and utility power source voltage available, the battery receives a trickle charge while the engine is not run- ning, to prevent self-discharge. The trickle charger is designed to help extend the life of the battery by maintaining the battery when the unit is not running. The trickle charge feature cannot be used to recharge a discharged battery.
