CLEANING THE SPARK ARRESTOR

Refer to Table 4 for scheduled cleaning of the spark

arrestor muffler. Cleaning is required for maximum

genset performance. Park the vehicle away from

grass, brush or debris that could be ignited by

sparks expelled during this procedure.

WARNING

A hot muffler can cause severe

burns. Let the muffler cool down before remov-

ing or installing cleanout plugs or screens.

Series HGJAA: A double-drum muffler is mounted

inside the genset. The cleanout plug is in the top

drum, but accessible from below, though not readily

visible. In Figure 15 a portion of the lower drum is

cut out so that the location of the plug is visible.

1. Locate the square-headed cleanout plug by

hand and solidly seat a 7/16 inch, eight point,

3/8 inch drive socket wrench with 3 inch exten-

sion on the plug. Then add a swivel section and

6 inch extension and turn with a ratchet to re-

move the plug.

2. Start and load the genset to near full power

(Page 9). Let the genset run for about five

minutes to expel the soot in the muffler.

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

and then reinstall the plug.

Series HGJAB: See Figure 15 if double-drum or

Figure 16 if single-drum. On a single-drum muffler

the cleanout plug is accessible from below as

shown in Figure 16.

1. Remove the plug with a 7/16 inch, eight point

socket wrench.

2. Start and load the genset to near full power

(Page 9). Let the genset run for about five

minutes to expel the soot in the muffler.

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

and then reinstall the plug.

Series HGJAC: The muffler is externally mounted.

If it has a clean out plug like the one shown in Fig-

ure 16, use the instructions for Series HGJAB as a

guide. Alternatively, the end of the tail pipe may

have a spark screen (Figure 17). If so, remove the

screw that secures the spark screen, clean the

screen with a wire brush and re-install it.
