CLEANING THE SPARK ARRESTOR

Refer to Table 3 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.

The cleanout plug is located on the side of the muf-

fler, accessible through the air outlet opening in the

bottom of the genset. Clean out the spark arrestor

muffler as follows:

1. Remove the cleanout plug from the muffler

(Figure 8).

2. Restart the genset and load it nearly to full pow-

er. See LOADING THE GENSET (Page 9).

Let the genset run for about five minutes to ex-

pel the soot in the muffler.

3. Stop the genset, allow the muffler to cool down

and then reinstall the plug.
