BATTERY INSTALLATION
This engine generator set is shipped with a bungee cord
for installation of the customer supplied battery in the
unit’s battery tray. If you intend to use the unit’s electric
start system, you will need to purchase and install a battery
to operate it. An Interstate IB18-A ,12 Volt battery or
equivalent is recommended for the electric start on this
engine-generator set. Follow the battery manufacturers
recommendations for servicing and charging prior to use.
Connect the battery to the electric start system using the
cables provided.
CAUTION: EQUIPMENT DAMAGE
These electric start engines are NEGATIVE GROUND.
Use extreme caution when connecting the battery.
Connect the NEGATIVE battery terminal to GROUND.
For your safety, always connect the positive battery cable to
the “bat+” terminal first. Then connect the negative battery
cable to the “bat-” terminal. Make sure all connections are
clean an tight. Reverse the sequence when disconnecting,
disconnect the negative cable first. These engines produce
enough direct current to keep the battery charged under
normal operating conditions, but were not intended to be
used as a battery charger.
WARNING: PERSONAL INJURY
Lead acid batteries produce explosive hydrogen gas
when charging. Keep sparks, flames, and burning
cigarettes away from the battery. Ventilate the area
when charging or using the battery in an enclosed
space. Lead acid batteries contain sulfuric acid, which
causes severe burns. If acid contacts eyes, skin, or
clothing, flush well with water. For contact with the
eyes, get immediate medical attention.
BATTERY CHARGING
Units have a small flywheel charger built into the engine
flywheel assembly for recharging the starting battery. This
flywheel charger generates a small AC current that passes
through a diode assembly to produce DC charging current
of about 1 to 3 Amps. This circuit is not designed to be used
as a battery charging circuit to recharge dead batteries.
LIFTING EYE INSTALLATION
The lifting eye is shipped loose along with a bag of parts.
Install the base of the lifting eye below the middle support.
