lead.

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 necessary.
NOTE:
Product users on United States forest service land,
and in some states, must comply with fire prevention
regulations.
Clean the spark arrester as follows: (Fig. 9 and 10)
1.
Remove the screw from the muffler and remove the spark
arrester.
2. Use a brush to remove carbon deposits from the spark
arrester screen. Be careful to avoid damaging the
screen.
The spark arrester must be free of breaks and holes.
Replace the spark arrester if it is damaged.
3.
Install the spark arrester and muffler protector in the
reverse order of disassembly.
Spark arrestors are available from your local Mi-T-M Customer
Service Representative. Other user requirements may apply,
