SPARK ARRESTOR:
If the generator has been running, the muffler will be very hot. Allow it to
cool before proceeding.
NOTE: Remove and clean spark arrester every 100 hours or as nec-
essary.

some states, must comply with fire prevention regulations.
Clean the spark arrester as follows: (Fig. 10A,B and 11)
1. Loosen the screw by the exhaust port of the muffler and remove the
spark arrester.
2. Use a brush to remove carbon deposits from the spark arrester screen.
Inspect the screen for breaks or tears and replace it if necessary.
3. Install the spark arrester in the reverse order of removal.
