Extension Cord Cable Size
Refer to the table below to ensure the cable size of the extension cords you use are capable of carrying the required load.
Inadequate size cables can cause a voltage drop, which can damage the appliance and overheat the cord.

Electric Motor Loads
It is characteristic of common electric motors in normal operation to draw up to six times their running current while starting.
This table may be used to estimate the watts required to start electric motors; however, if an electric motor fails to start or
reach running speed, turn off the appliance or tool immediately to avoid equipment damage. Always check the requirements
of the tool or appliance being used compared to the rated output of the generator.

Operating voltage and frequency requirement of all electronic equipment should be checked prior to plugging
them into this generator. Damage may result if the equipment is not designed to operate within a +/- 10% voltage
variation, and +/- 3 hz frequency variation from the generator name plate ratings. To avoid damage, always have
an additional load plugged into the generator if solid state equipment (such as a television set) is used. A power
line conditioner is recommended for some solid state applications.
