CLEANING THE SPARK ARRESTOR
The spark arrestor cleanout plug is located on the
side of the muffler (Figure 3-3). Clean out the spark
arrestor as follows:
Refer to Table 3-1 for scheduled cleaning of the
spark arrestor (which meets U.S. Forest Service requirements). Cleaning is required for maximum
genset performance.
1. Remove the 1/4” NPT cleanout plug from the
muffler.
2. Start the genset and load it nearly to full power.
Let the genset run for about five minutes to expel the soot.
WARNING A hot muffler can cause severe
burns. Let the muffler cool down before removing or installing the cleanout plug.
3. Stop the genset, allow the muffler to cool down,
reinstall the cleanout plug.
