OPERATION
Economy Control Switch
The Economy Control switch can be activated in order to minimize fuel consumption and noise
while operating the unit during times of reduced electrical output, allowing the engine speed to
idle during periods of non-use. The engine speed returns to normal when an electrical load is
connected. When the economy switch is off, the engine runs at normal speed continuously.
NOTICE:
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.
NOTICE
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.
WARNING!
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.
