Replacing the HC and CO Filters
1. Verify that the GX-2003 is off.

chamber on the back of the GX-2003. The HC filter is in the
position closer to the exhaust and has a yellow label around its
position. The CO filter is below the HC filter and has a red label
around its position.
3. If the filter does not come out with the filter retainer, carefully
remove it from the flow chamber.
4. Discard the old filter and snap the colored side (yellow for HC and
red for CO) of the new filter into the filter retainer.
