GENERATOR APPLICATION

WHAT IS A GENERATOR

A generator is basically a prime mover, typically a gasoline or
diesel engine, coupled to an alternator to produce electricity. It
is very useful as a substitute power source during power
outages or as the primary source in remote locations where
power is not available. Generators are essential for people
such as contractors or farmers who are always in need of
portable power. They are also very convenient for recreational
use.

SELECTING A GENERATOR

Selecting the proper generator is important. A generator that is
too small for your application will not run all of the equipment
needed. A generator that is too large will cost more and if
never used to its potential the money is wasted. The correct
size generator is determined by totaling the wattage
requirements of the items to be used simultaneously,
determine additional starting wattage requirements and total
these numbers. Select a generator with a continuous rating
that exceeds this by about 20% to allow for expansion. See the
table in the section titled “Generator Set Overload” for some
wattage guidelines of common equipment.

RATED vs. SURGE WATTS

Rated

, or continuous, watts are the watts an item needs as it is
running.
Surge

, or maximum, watts are the watts an item needs to start.
This is typically 2-4 times the rated watts.
This information is typically provided on the manufacturer’s
nameplate. If watts are not provided, it can be calculated using
the formula: Watts=Amps x Volts.

EXTENSION CORDS

An extension cord should always be in good condition with no
damage to the wires or sheathing. Never run an extension cord
through water. The correct wire size for an extension cord can
be determined from the table that follows.

LOADING YOUR GENERATOR SET

With reference to the Receptacle details section, please review
the power receptacles fitted to your generator. The circuit
breaker rating and the generator rating drive the actual load
that may be pulled from each receptacle. The ratings shown in
the table are the maximum available from each receptacle.
DO NOT EXCEED THE INDIVIDUAL RECEPTACLE RATINGS

AS SHOWN IN THE TABLE BELOW. DO NOT EXCEED THE
TOTAL GENERATOR NAMEPLATE RATING. All generator
units are equipped with a thermal-magnetic main circuit
breaker as well as a "PUSH TO RESET" breaker on branch
circuits.

AMPERAGE RATE TABLE

ENGINE LIMITATIONS ON GENERATOR

PERFORMANCE

Generator ratings assume 60°F (20C) and Sea Level.
Operation of your generator at temperatures above 60°F (20C)
or above Sea Level will result in lower electrical output.
Electrical output must be derated 1% for each 10°F above
60°F and 3 ½ % for each 1000 feet above mean sea level.

GENERATOR CLEANING

CAUTION: ALWAYS SHUT DOWN THE GENERATOR

AND ALLOW IT TO COOL COMPLETELY BEFORE

PERFORMING CLEANING OPERATIONS.

WARNING: DO NOT USE HIGH PRESSURE WATER

OR A GARDEN HOSE TO CLEAN YOUR
GENERATOR. WATER INTRODUCED INTO THE
GENERATOR CAN CAUSE ELECTRICAL SHORTS,
GENERATOR DAMAGE OR PERSONAL INJURY.

• Compressed air (max. 25 psi) may be used to blow loose

dirt and dust from your generator. DO NOT DIRECT
COMPRESSED AIR DIRECTLY INTO ANY OPENING IN
THE GENERATOR OR ENGINE.

• Use a dampened cloth to wipe clean exterior surfaces.

• Use a soft bristle brush to clean/ loosen heavy dirt, oil or

grease deposits.

• NEVER insert rags, tools or any device into the generator

or engine openings.

GENERAL STORAGE GUIDELINES

WARNING: GASOLINE FUEL FUMES ARE

FLAMMABLE. DO NOT STORE YOUR GENSET IN

ANY AREA THAT IS INDOOR OR IN POORLY
VENTILATED AREAS. GASOLINE FUEL FUMES CAN
IGNITE IN THE PRESENCE OF ANY OPEN FLAME, PILOT
LIGHT, CLOTHES DRYER, WATER HEATER, ETC.

Your generator should be started and operated for
several minutes at least every 30 days. When the generator
set is not being operated or is being stored more than one
month, follow these instructions:

1. Replenish engine oil to upper level.

2. Run the generator, then close the fuel shut-off valve and

allow the unit to run until the engine stops.

3. Move the engine switch to the “OFF” position.

4. After the unit has cooled, drain gasoline from fuel tank,
fuel line and carburetor.

5. Pour about one teaspoon of engine oil through the spark
plug hole, pull the recoil starter several times and replace
the plug. Then pull the starter until you feel the piston is
on its compression stroke and leave it in that position. This
closes both the intake and exhaust valves to prevent the
inside of the cylinder from rusting.

6. Cover the unit and store in a clean, dry place that is well
ventilated away from open flame or sparks.

NOTE: We recommend always using a fuel stabilizer.

A fuel stabilizer will minimize the formulation of fuel gum
deposits during storage. The fuel stabilizer can be added
to the gasoline in the fuel tank, or into the gasoline in a
storage container.
