For periods of high electrical load or momentary
fluctuations, the Economy Control Switch should be
turned OFF.
12V DC Outlet (Battery Charger)
The 12V DC outlet is ONLY to be used with the
supplied 12V battery charging cable. The DC output
is unregulated and will damage other 12V DC
products.
The amount of current flowing will depend on the
charging voltage and battery's state of charge. As
the battery becomes more fully charged, the output
current to the battery decreases and nearly becomes
constant. Taper chargers are intended to be used
with the provision that they will be disconnected
from the battery after a maximum time on charge.
Normally a period of 30 to 120 minutes is sufficient
to recharge a weak battery.
The charge level of the
battery should be checked
periodically.
•For use with 12V direct current outlet, always
keep the ECO mode deactivated (OFF Position).
•You can use the 12V direct current outlet and
the
120V current at the same time, but keep the ECO
mode deactivated (OFF Position) at all times. Do not
start the vehicle while the battery charging Cable is
connected and the generator is running. It will not
give the battery a boost of power. The Vehicle or
the generator may be damaged. Charge only
vented wet lead acid batteries. Other types of
batteries may burst, causing personal injury or
damage.
Storage batteries give off EXPLOSIVE hydrogen gas
while charging. Do not allow smoking, open flames,
sparks, or spark producing equipment in the area
while charging.
Battery electrolyte fluid is comprised of sulfuric acid
that can be very dangerous and cause severe burns.
Do not allow this fluid to contact eyes, skin,
clothing, etc. If contact or spillage does occur, flush
the area with water immediately. Do not continue
to charge a battery that becomes hot or is fully
charged.
1. Before connecting the battery charging cable to a
battery that is installed in a vehicle, disconnect
the vehicle battery ground cable from the
negative (–) battery terminal.
2. Plug the battery charging cable into the
DCreceptacle of the generator.
3. Connect the red (+) battery charger lead to the
red (+) battery terminal.
4. Connect the black (–) battery charger lead to the
black (–) battery terminal.
5. Start the generator.
NOTE:
When the battery circuit is in use the AC capacity is
reduced by 100 watts. Make sure the combined load
is within the rated limits.
Do not continue to charge a battery that becomes
hot or is fully charged.
DC CIRCUIT PROTECTOR
A DC circuit protector has been provided to protect
the circuit from overloads. If an overload occurs, the
circuit protector will trip. The circuit protector may
be reset by pushing the button of the protector.
Charging a large capacity battery or a totally
discharged battery may cause the DC breaker to turn
off. In these cases, a separate battery charger unit
connected to an AC power source is recommended
instead of the DC receptacle on the generator.
Stopping the Engine
1. Turn off and remove entire electrical loads.
Never start or stop the generator with
electrical devices plugged in or turned on.
