SPARK ARRESTOR MUFFLER

•  The spark arrestor muffler controls the exhaust 

noise and prevents hot, glowing particles of  

carbon from leaving the muffler.  

Make sure the spark arrestor screen is in good 

repair and properly seated in the muffler. 

•  Certain internal combustion engines operated on 

forest, brush, and/or grass-covered areas in the 

states of Washington, Oregon, Idaho, California, 

Minnesota, New Jersey and Maine, are required 

to be equipped with a spark arrestor.

This requirement also applies to all U.S. Forest 

Service lands.  

In some of these areas, the spark arrestor system 

must be certified per USDA Forest Service  

Regulation SAE J335.  

Check with your local or state authorities for  

specific regulations in your area.  

Failure to follow these requirements is a violation 

of the law. 

   DANGER

Kickback safety precaution for chain saw 

users: Kickback may occur when the nose 

or tip of the guide bar touches an object or 

when the wood closes in and pinches the 

saw chain in the cut.

The installation of a chain brake may be mandatory 

by law or as stipulated by insurance regulations in 

your area of operation.  

You should inquire through local government  

offices, your employer or your local dealer to  

ensure that your chain saw conforms to the  

required safety standard.  

ECHO chain brakes have been designed and 

tested to comply with international safety standards 

as follows.  

This model needs to use low-kickback chain and 

bar.   

Do not use a combination other than those  

specified on page 23.  

For your own safety, do not remove the chain 

brake system.
