Some machines may have an electrical outlet at the
platform, but no power-input connector on the chassis. In
that case, power is supplied by an optional AC generator.
An external power source is not required.
With the engine running, place the machine/generator
control (refer to Figure 7.21) in the generator position to
provide electrical power to the outlet at the platform and
to the outlet on the end of the generator housing.
Figure 7.21 – Upper Controls
Plug an electrical tool into the receptacle at the platform
and at the generator and try to operate the tool to verify
proper operation of the outlet.
The outlet at the platform is equipped with a ground fault
circuit interrupter (GFCI). Use the following procedure to
test the GFCI.
1. Push the test button (refer to Figure 7.22).
