BATTERY MAINTENANCE (cont.)

	Table A
Display	Operating Condition
Red	•When the red LED is on, it indicates that
	your battery is discharged and the charger
	is recharging at the "BULK" rate of 6
	Amps. •While the red LED is on, the
Green	voltage measured will be 11.8 to 14 volts.
	•If the red LED stays on for more than 24
	hours, refer to the troubleshooting section
	of this manual.
	•When both the green and the red LED's
Red	are on, the charger is charging at an
	"ABSORPTION" rate of between 1.5 and 5
	Amps. This mode of charging gradually
	"tops off" the battery, and reduces harmful
	sulfating. •While both LED's are on, the
Green	voltage measured should be approx. 14.0
	to 14.5VDC. •If both LED's stay on longer
	than 24 hours, refer to the troubleshooting
	section in this manual.
	•When the green LED is on, the charger is
Red	charging at a "FLOAT" rate of less than
	1.5 Amps. •This "float" charging current
	will gradually decrease to as low as 0.1
	Amps as the battery reaches 100%
	charge. It will now be kept at full charge
Green	without over-charging. •If the green LED
	stays on when the battery is known to be
	low, refer to the troubleshooting section of
	this manual.

SPARK PLUG CHECK

Engine spark plugs are an important part of the engine ignition system. Worn or incorrectly adjusted spark plugs can negatively affect engine starting and operation. Therefore, it is important to inspect and regap, or replace the engine spark plugs as indicated in the service interval table. The listed steps are recommended to access and service the engine spark plugs.

WARNING

•Before performing any maintenance, make sure the Mode switch is in the OFF position, the circuit breaker is in the OFF position and the positive (red) battery cable is disconnected.

1.Access the spark plugs by removing the front and back generator panels. Insert the key into the top locks and turn 1/4 turn counterclockwise to unlock. Lift the panels up and out of the base and set them aside.

2.Pull the spark plug boots loose, then clean any dirt from the area around the spark plugs. Remove the spark plugs with a 13/16" spark plug wrench.

3.Inspect the spark plugs for fouling or abnormal wear like excessively worn electrodes or cracked or chipped insulator material. If abnormal wear is indicated, replace the spark plugs. Fouled plugs indicate the need for engine service by a qualified engine service technician.

New spark plugs or plugs that do not display any abnormal characteristics should be checked for proper gap using a suitable spark plug gauge. Adjust the gap to .035 inches (.889 mm) by carefully bending the grounding electrode.

4.Reinstall the spark plugs by hand until they begin to seat to avoid cross-threading. After the plugs begin to seat, tighten plugs an additional ¼ turn with a 13/16" spark plug wrench to avoid damage to the spark plugs. If a torque wrench is available, tighten all plugs to 13 in-lbs (18 N-m).

5.Reassemble the front and back panels to the generator by setting the bottom end of the panel into the base and push into place. Insert the key into the top locks and turn 1/4 turn clockwise to lock.
