GENERATOR CAPACITY
Exceeding the rated capacity of your generator can
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 should
always be calculated when matching a generators
wattage capacity to the appliance or tool.
• There are two types of electrical appliances that
can be powered by your generator:
A. Items such as radios, light bulbs, television
sets, and microwaves have a "resistive load".
Starting wattage and running wattage are the
same.
B. Items such as refrigerators, air compressors,
washer, dryer, and hand tools that use an
electrical motor have an "inductive load".
Inductive load appliances and tools require
approximately 2 to 4 times the listed wattage
for
starting the equipment. This initial load
only lasts for a few seconds on start-up but is
very important when figuring your total
wattage to be used.
NOTE: Some inductive appliances and tools will list
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)
• Always start your largest electric motor first, and
then plug in other items, one at a time.
The guide is provided to assist you in determining the
appliances and tools that can be ran with the wattage
capacity of your generator.
OBTAINING ELECTRICITY FROM
GENERATOR
There are basically two ways to obtain electricity from
a generator:
• Use of extension cords directly from the generator to the appliance, lights, tools, etc.
• Use of a double-throw transfer switch installed
directly to the main electrical supply outside of
the house.
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-slot receptacle that accepts the tool's plug MUST be used in
order to reduce the risk of electrical shock. 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.
An extension cord that is hot
to the touch is overloaded.
Repair or replace damaged extension cords
immediately.
Connecting Generator To Main Electrical
Supply
Potential hazards exist when a electrical generator is
connected to the main electrical supply coming into
the house. It is at that point that the generator could
feed back into the utility company’s system causing
possible electrocution of workers who are repairing
electrical lines. To avoid back feeding of electricity into
utility systems, a double-throw transfer switch
should be installed between the generator and utility
power. This device should be installed by a licensed
electrician and in compliance with all local electrical
codes.
NOTE: When installing a Double-Throw Transfer
Switch, a minimum of 10 gauge wiring must be used.
11 — ENG
D20346 Rev. 0 2/28/00
BEFORE STARTING ENGINE
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.
Adding Engine Oil
Your generator has been shipped without oil in the
engine. Begin by removing the oil dipstick and plug.
Start pouring the oil in slowly.
The engine will hold approximately 20 ounces of oil. To
check the oil, clean and replace the dipstick. Do not
screw the dip stick in when checking the oil level. Next,
remove the dipstick to check the level. The oil dipstick
is clearly marked with lines that tell you when the
engine has enough oil. Do not fill above this point.
Oil Fill
Plug
Use clean, fresh, regular unleaded gasoline with a
minimum of 85 octane. Do not mix oil with gasoline.
Never fill fuel tank com-
pletely. Fill tank to 1/2" below the bottom of the
filler neck to provide space for fuel expansion.
Wipe any fuel spillage from engine and equipment before starting engine.
• Do not overfill.
Never fill fuel tank indoors.
Never fill fuel tank when engine is running or
hot. Do not smoke when filling fuel tank.
To Start Your Generator
Never run engine indoors or
in enclosed, poor ventilated areas. Engine
exhaust contains carbon monoxide, an
ordorless and deadly gas.
Fill To
Overflowing
NOTE: When adding oil to the engine crankcase, use a
high quality detergent oil classified “For Service
SF,SG,SH” rated SAE 30 weight. Use no special additives.
Select the oil’s viscosity grade according to your expected
operating temperatures.
Gasoline
Your generator engine is 4 cycle. Use unleaded fuel
only. Never mix oil with gasoline.
• Remove gas cap.
• Move the choke control located on the engine to
"CHOKE" position.
NOTE: No choke is required on warm engines. Make
sure choke is in the "NO CHOKE " position on warm
engine starts.
