• The spark arrestor muer controls the exhaust
noise and prevents hot, glowing particles of
carbon from leaving the muer.
Make sure the spark arrestor screen is in good
repair and properly seated in the muer.
• 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.
CORRECT USE OF CHAIN BRAKE

This requirement also applies to all U.S. Forest Ser-
vice lands.
In some of these areas, the spark arrestor system
must be certied per USDA Forest Service
Regulation SAE J335.
Check with your local or state authorities for
specic 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
oces, 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 fol-
lows.
This model needs to use low-kickback chain and bar.
Do not use a combination other than those
specied on page 23.
For your own safety, do not remove the chain brake
system.
