Never exceed the rated capacity of your generator. Serious damage to the

generator or appliance could result from an overload.

1. Starting and running wattage requirements should always be calculated when

matching a generators wattage capacity to the appliance or tool.

2. There are two types of electrical appliances that can be powered by your

generator:

Items such as radios, light bulbs, television sets, and microwaves have a

"resistive load". Starting wattage and running wattage are the same.

Items such as hand tools that use an electrical motor have an "inductive

load". Inductive load appliances and tools require approximately 2 to 3

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.

Always start your largest electric motor first, and then plug in other

items, one at a time.

NOTE: On 120-volt loads the maximum starting wattage should NOT exceed

1250 watts.

DETERMINING WATTAGE REQUIREMENTS

Before operating this generator list all of the appliances and/or tools that are going

to operate at the same time. (Then determine the starting wattage requirements and

the running wattage requirements by following example and/or refer to household

wattage calculator.)

First total the running wattage of all appliances and/or tools that will be

operated at the same time.

Example 1:

Lights

Television

Next the starting wattages of any appliances and/or tools that will start and

stop during operation.

Example 2:

Blender

TOTAL

The running wattage of examples 1 & 2 totals 800 watts. The starting wattage

of the blender is 800 watts which is 400 watts more than the running watts.

Take this difference of 400 starting watts from the blender and add to the total

running watts of 800.

Example 3:

TOTAL

Generator must have a maximum capacity of at least 1200 watts.
