3.7 SPARK ARRESTOR MUFFLER

If the generator is not equipped with a spark arrestor

exhaust muffler and is to be used on any forest cov

ered, brush covered or grass covered unimproved

land, you may have to install a spark arrestor. The

spark arrestor must be maintained in effective work

ing order by the vehicle owner/operator.

For assistance in ordering, installing and maintaining

spark arrestor exhaust mufflers, contact your nearest

Generac Authorized Service Dealer.

Exhaust mufflers supplied by Generac are spark

arrestor types. Generac exhaust mufflers for recre

ational vehicle generators do not have a spark

arrestor screen, but are of the more efficient “toroid”

or “swirl” type. To remove carbon and combustion

deposits from such mufflers, remove the plug from

the muffler and run the engine for approximately 15

minutes. Shut down the engine, let the muffler cool

and install the plug.
