AUTOMATIC VOLTAGE REGULATOR
The following is a list of connections on the AVR. These
have been factory set and other than voltage adjustment,
should never be changed.
TERMINALS
Terminal 1 - Excitation Negative
Terminal 2 - Excitation Positive
Terminal 3 - AVR Power Supply
Terminal 4 & 5 - Voltage Sensing Input
Terminal 6 & 7 - Common for Sensing and Power Supply
VOLTS
To adjust generator output voltage.
Clockwise to increase voltage.
STAB
To prevent voltage hunting.
Clockwise to decrease stability and consequently the
response time.
HZ
Sets the intervention level of the under-frequency
protection.
These have been factory set and should never be
changed.
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.
A 12 Volt battery, group U1 rated at 275 CCA or larger is
recommended for this electric start 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.
See diagram below.
OPTIONAL DOLLY KIT
An optional 2-wheel dolly kit is available for this generator.
The dolly kit comes with its own instructions and parts list.
CAUTION: EQUIPMENT DAMAGE
Be sure to check the wheels properly before operating the
generator.
