CLEANING THE SPARK ARRESTOR
Refer to Table 3-1 for scheduled cleaning of the
spark arrestor muffler (which meets U.S. Forest
Service requirements). Cleaning is required for
maximum genset performance.
WARNING
A hot muffler can cause severe
burns. Let the muffler cool down before remov-
ing or installing the cleanout plug.
The muffler is mounted inside the genset housing
(Figure 3-3). The spark arrestor cleanout plug is lo-
cated on the side of the muffler and is accessible by
removing the top enclosure panel. Clean out the
muffler as follows:
1. Remove the top enclosure panel.
2. Remove the cleanout plug from the muffler. Se-
cure the top enclosure panel before running the
genset. With the cover in place there will be
enough air flow to cool the engine properly and
carry the soot out of the compartment.
3. Start the genset and load it nearly to full power.
Let the genset run for about five minutes to ex-
pel the soot.
4. Stop the genset, allow the muffler to cool down,
reinstall the cleanout plug and secure the top
panel.
