Step 1

Before you begin, make sure the generator is off and cool to the touch.
Use a large flathead screwdriver to unlock the maintenance cover.
Open the maintenance cover.

Step 2

Use a Phillips screwdriver to remove the screw securing the spark plug cover.
Remove the spark plug cover.

Step 3

Grab the plastic housing at the end of the spark plug wire.
Pull firmly to disconnect the wire from the spark plug.

Step 4

Turn the fuel valve to the cutoff position.

Step 5

Use a 10 mm socket to remove the four capped nuts securing the front cover.
Remove the front cover.

Step 6

Use an 8 mm socket to disconnect the battery wires from the battery terminals.
Disconnect the black negative cable first to prevent the risk of shorting the battery.
During reassembly, connect the black negative cable first. Make sure you reconnect the wires in the correct polarity.

Step 7

Unclip the battery strap from the lower plate.

Step 8

Remove the battery.

Step 9

Use a 10 mm socket to remove the four capped nuts securing the lower plate.
Set these capped nuts apart. They look similar, but are smaller than the front cover nuts.
Remove the lower plate.

Step 10

Insert a flathead screwdriver into the top of the brown fuse clip in order to release the fuse holder.
Detach the fuse holder from the brown clip.

Step 11

Use pliers to lift and disconnect the choke cable from the choke stay.
During reassembly, be sure to test the choke to ensure that it is properly connected.

Step 12

Use a long shaft Phillips screwdriver to remove the deeply recessed screw securing the fuel cutoff switch.
Be careful not to turn the fuel cutoff switch while you remove the screw.

Step 13

Remove the fuel cutoff switch.
During reassembly, be sure to test the switch to ensure that it is properly installed.

Step 14

Use a 10 mm socket to remove the four bolts securing the control panel.

Step 15

Carefully tilt the control panel downwards.
The control panel will still be connected to many wires and cables. Be careful not to strain any of the connected wires.

Step 16

Remove the following bolts securing the inverter:
One 8 mm ground bolt
Three 10 mm bolts (one behind the control panel)

Step 17

Reach behind the inverter along the edges and disconnect the six connectors from the back of the inverter.
All the connectors use locking tabs, so you will have to squeeze them in order to release them.
The third image shows the locations of all six sockets on the inverter.
Reassembly tip: Every socket on the inverter is different, so you can't plug something into the wrong place. Do not force the connectors into their sockets.

Step 18

Remove the inverter.

Step 19

If you are replacing the inverter and the replacement did not come with rubber mounts, follow the next two steps to transfer them over.
Use a screwdriver to push the metal collar out of the center of the rubber mount.
