DON'T OVERLOAD

C adty

You must make sure your generator can supply enough
rated (running) and surge (starting) watts for the items you
will power at the same time. Follow these simple steps:

I. Select the items you will power at the same time.

2. Total the rated (running) watts of these items.This is

the amount of power your generator must produce to
keep your items running. See Figure 8.

3. Estimate how many surge (starting) watts you will

need. Surge wattage is the short burst of power
needed to start electric motor-driven tools or

appliances such as a circular saw or refrigerator.
Because not aJJmotors start at the same time, total

surge watts can be estimated by adding only the

item(s) with the highest additional surge watts to the
total rated watts from step 2.

Power Manasement

To prolong the JJfeof your generator and attached devices,
it is important to take care when adding electrical loads to
your generator.There should be nothing connected to the
generator outlets before starting it's engine.The correct
and safe way to manage generator power is to sequentially

add loads as follows:

I. With nothing connected to the generator, start the

engine as described in this manual.

2. Plug in and turn on the first load, preferably the largest

load you have.

3. Permit the generator output to stabilize (engine runs

smoothly and attached device operates properly.

PRODUCT

INFORMATION

This is a single cylinder, overhead vaIve(OHV), air cooled
engine. [t is a low emissions engine.

In the State of California, Model Series J20000 engines are
certified by the Ca[ffornh Air Resources Board to meet

emissions standards for 125 hours. Such certification does
not grant the purchaser, owner or operator of this engine

any additional warranties with respect to the performance
or operational life of this engine.The engine is warranted

solely according to the product and emissions warranties
stated elsewhere in this manual

Power Ratings

_The power ratings for an individual engine model are
initially developed by starting with SAE (Society of
Automotive Engineers) code J[ 940 (Small Engine Power &
Torque Rating Procedure) (Revision 2002-05). Given both
the wide array of products on which our engines are
placed, and the variety of environmental issues applicable to
operating the equipment, it may be that the engine you
have purchased will not develop the rated horsepower
when used in a piece of power equipment (actual "on-site"
power).This difference is due to a variety of factors
including, but not limited to, the following: differences in

altitude, temperature, barometric pressure, humidity, fuel,
engine lubrication, maximum governed engine speed,
individual engine to engine variability, design of the
particular piece of power equipment, the manner in which
the engine is operated, engine run-in to reduce friction and
clean out of combustion chambers, adjustments to the
valves and carburetor, and other factors.The power ratings
may also be adiusted based on comparisons to other
similar engines utilized in similar applications, and will
therefore not necessarily match the values derived using
the foregoing codes.

are visible on its exterior surface.

NOTE: DO NOT use water or other liquids to dean
generator. Liquids can enter the engine fuel system causing
poor performance and / or failure to occur. [n addition, ff

liquids enters the generator through cooling air slots, some
of the liquid will be retained in voids and cracks of the rotor
and stator winding insulation. Liquid and dirt buildup on the
generator internal windings will eventually decrease the

insulation resistance of these windings.

Generator Cleaning

DaJJyor before use, dean accumulated debris from
generator. Keep linkage, spring and controls clean. Keep area
around and behind muffler free from any combustible debris.

Generator parts should be kept dean to reduce the risk of
