7.5CLEANING SPARK ARRESTOR SCREEN

WARNING

Muffler reaches temperatures that can cause serious burns if touched. NEVER touch hot surfaces.

The generator muffler is equipped with a spark arrestor screen, which must be cleaned according to the mainte- nance schedule (see Table 7-1) to ensure prevention of sparks escaping generator.

To clean spark arrestor screen, you will need:

1/4” socket wrench

8 mm socket

7/32” socket

#2 Phillips screwdriver

Wire brush

1.Stop the engine if it is running. Allow to completely cool.

2.Place generator on a flat, level surface.

3.Using a socket wrench with an 8 mm socket, remove the muffler cover bolts (muffler cover not present on HW3000 or HW3000L models).

4.Remove muffler cover.
