GENERATOR CAPACWY
Exceeding the rated capacity of your generator carl
result in serious damage to your generator and connected
electrical devices. You should observe the following to
prevent overloading the unit:
Starting and running wattage requirements must be
calculated to match your generator wattage capacity.
Resistive load appliances such as light bulbs, TV's
and microwaves, have the same starting and running
wattage. The wattage used for calculating the capacity
can usually be found on each of these appliances.
Some inductive appliances and tools wiii iist on the motor
name plate, the starting and running voltage and amperage
requirements. Use the following formula to convert voltage
and amperage to wattage:
_Volts X Amp = Watts}
Inductive load appliances and tools such as refrigerators,
air compressors and washers require approximately 2 to
4 times the listed running wattage for starting the equip-
ment. This initial load only lasts for a few seconds on
start-up but isvery important when figuring your total
wattage to be used.
NOTE: Always start your largest electric motor first, and
then plug in other items, one at a time.

OBTAmNING ELECTRBC_TY FROM
There are basicaiiy two ways to obtain eiectrbity form a
generator:
Use of extension cords directly form the generator
to the appiiance, iights, toois, etc.
Use of a doubie-throw transfer switch instaiied
directly to the main eHectrbaHsuppiy outside of the
house.
Start the engine. Let it run while the battery charges.
When the battery is fully charged, stop the engine
and disconnect the battery charge canes from the
panel and battery. Batteries should not be charged
when the unit is unattended.
NOTE- _ llb not use the -_t to c_ any 6_olt _atteries°Ds
not use the unit to crank an engine having a discharged
b_ttey°
Extension Cord
When using an appliance or tool at a considerable distance
from the generator, a 3-wire extension cord that has a 3-
blade grounding plug and 3-dot receptacle that accepts
the tool's plug should be used. A cord of adequate size
must be used. A minimum of 12 gauge wire size with at
least a 20 amp draw can be used. When amperage
exceeds 20 amps a 10 gauge wire size should be used.
Connecting Generator To Main Eleetrieam
SuppJy
Potenfiai hazards exist when a eiectricai generator is con-
nected to the main eiectricai suppiy coming into the house.
It is at that point that the generator couid feed back into the
utiiity company's system causing possibie eiectrocution of
workers who are repairing electrical lines. To avoid back
feeding of electricity into utility systems, a double-threw
transfer switch should be installed between the genera-
tor and utility power. This device should be installed by a
licensed electrician and in compliance with all local electri-
cal codes.
NOTE: When installing a Double-ThrowTransfer Switch,
a minimum of 10 gauge wiring must be used.
CHARGBNG A BATTERY
iMPORTANT: Always use safety glasses, rubber gloves
and protective clothing while charging battery.
Your generator has the capability of recharging a 12-volt
storage or automotive battery. To recharge a 12-volt
battery, proceed as follows:
First, check the fluid level in all of the battery cells.
Add distilled water if necessary. Do not use tap
water,
Clean battery posts if necessary.
Connect battery charge canes to panel receptacle
BEFORE STARTRNG ENGINE
CAUTION: Always check engine oil level before
every start. Running engine low of oil or out of oil
could result in serious damage to the engine
Automatic BdUeControU
The automatic idle control switch, when in the ON posi-
tion, allows the engine to run at lower speed when there
is no load on the generator. This wiii lower the engine
noise, save on fuel consumption and engine life. When in
