SPARK ARRESTOR CLEANING

In some areas of the United States, a USDA Forest Service approved exhaust spark arrestor is legally required. This optional accessory is added to the generator during initial installation. To identify whether the generator is equipped with a spark arrestor, inspect the exhaust tailpipe opening for a screen. If a screen is present in the tailpipe, the spark arrestor option is installed.

Spark arrestors require periodic inspection and cleaning as indicated in the recommended service interval table on page 25. To maintain the spark arrestor, the following steps are recommended.

1.To gain access to the spark arrestor assembly inside the exhaust chamber, some disassembly of the generator cabinet is required. Begin the disassembly by carefully removing the lid from the enclosure. First push in the hinge retaining stop (A), then slide the lid (B) to the left to free it from the rest of the enclosure as shown in Fig GG. Set the lid aside on a soft surface to avoid scratching the lid paint.

2.Open the battery access panel by removing the 3 screws and rotating the panel outward (see Fig. E on page 28).

3.Remove the 2 screws (C) fastening the exhaust chamber panel (D) to the rear engine firewall (see Fig HH). Slide the exhaust chamber panel (D) upward to free it from the enclosure and carefully set it aside.

4.Remove the spark arrestor assembly by loosening the screw holding the arrestor to the muffler.

5.Use a low pressure stream of compressed air or water to blow particles from the spark arrestor screen. Ensure that all particles are completely flushed from the tailpipe.

6.Visually inspect the spark arrestor screen to for holes or breaks in the screen. If any are found, replace the spark arrestor assembly.

7.Reinstall the spark arrestor on the muffler outlet and replace the clamp.

8.Slide the exhaust chamber panel (D) back into place and install the screws (C) holding it to the rear engine firewall.

9.Slide the lid (B) back onto the hinges and reinstall the retaining clip to secure the lid place.
