LOW OIL SHUTDOWN

Your Sears generator engine is equipped with Low Oil Shutdown. Low Oil Shutdown is a safety device designed to protect your engine from damage in the event the oil level in the crankcase is low.

If while the engine is running, the oil gets low, it will automatically shut itself down and will not restart until the oil is added. If the oil is low before start-up, the generator will not start until oil is added.

NOTE: The Low Oil Shutdown mechanism is very sen- sitive. You must fill the engine to the full mark on the dipstick to inactivate this safety device.

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 follow- ing 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.

NOTE: On 120-volt loads the maximum starting watt- age should NOT exceed one half of the rated generator wattage. Example: a 5250 rated wattage generator = 2625 maximum starting wattage.

The guide is provided to assist you in determining the appliances and tools that can be ran with the wattage capacity of your generator.

Application Guide

To select the right generator for your needs, total the wattage of the items to be run at the same time.

OBTAINING ELECTRICITY FROM GENERATOR

There are basically two ways to obtain electricity form a generator:

•Use of extension cords directly from the genera- tor 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 recep- tacle 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.

An extension cord that is hot to the touch is overloaded.

Repair or replace damaged extension cords immediately.
