Know Generator Limits

Overloading a generator in excess of its rated wattage
capacity can result in damage to the generator and to
connected electrical devices. Observe the following rules
to avoid overloading:
•
Add up the total wattage of all electrical devices to be con-
nected at one time. The total should NOT be greater than
the wattage capacity of the generator.
•
The rated wattage of lights can be taken from light bulbs.
The rated wattage of tools, appliances and motors can
usually be found on a data label or decal affixed to the
device.
•
If the appliance, tool or motor does not give wattage, multi-
ply volts times ampere rating to determine watts (volts x
amps = watts).
•
Some electric motors, such as induction types, require
about three times more watts of power for starting than for
running. This power surge lasts only a few seconds. To
allow for high starting wattage when selecting electrical
devices to connect to the generator, proceed as follows:
Figure the watts needed to start the largest motor.

Add to that figure the running watts of all other connected

one time.

Before Starting Generator

Running
Watts
Add engine oil and gasoline to the generator before oper-
ation. Proceed as follows:
Add Engine Oil
All oil should meet minimum American Petroleum Insti-
tute (API) Service Class SJ, SL or better. Use no special
additives. Select the oil's viscosity grade according to the
expected operating temperature (also see chart).
•
Above 40° F, use SAE 30
•
Below 40° F and down to 10° F, use 10W-30
•
All temperatures, use synthetic 5W-30
Use petroleum based oil for engine break-in before using
synthetic oil.
