OPM-128/E
120 Volt and 240 Volt receptacles are provided for
connection to various loads.
The diagram below represents this 4,500 watt (rated
output) generator. A & B represent the 120 volt output
legs of this generator. Up to 2,250 watts at 120 volts
(37.5 Amps) can be drawn from the receptacles attached
to either A or B output legs. This generator is capable of
producing 37.5 Amps of 240 volt current at C. Check the
appliance or tool nameplates for the current and voltage
to insure compatibility. Remember that power taken from
C reduces the power available equally at both A and B and
vice versa.
Change Oil Warning -
After the first 50 hours, the engine oil should be changed.
The YourGen meter will light up the oil icon ( ) and the
word ‘change’ will flash. Once the oil has been changed,
press and hold the cycle button for approximately 5
seconds until the warning has been removed from the
display to reset the warning. The meter will then remind
you of oil changes on the appropriate schedule for your
generator. It is important to remember that the engine
manufacturer recommends changing the oil on a calendar
schedule even if the total number of operational hours have
not been reached. Certain operating environments may
also require more frequent oil changes.

disconnecting the spark plug and then open the
receptacle panel. Locate the backside of the YourGen
meter. Gently pry the back plate off using the slot
located on top.
2. Once open, the battery will be located at the top.
Using a needle nose plier, carefully pull out the
