Stihl BT 131 Instruction Manual page 13

WARNING
Never test the ignition system with the
spark plug boot removed from the spark
plug or with a removed spark plug, since
uncontained sparking may cause a fire.
WARNING
Use the specified spark plug and make
sure it and the ignition lead are always
clean and in good condition. Always
press spark plug boot snugly onto spark
plug terminal of the proper size. (Note: If
terminal has detachable SAE adapter
nut, it must be securely attached.) A
loose connection between spark plug
terminal and the ignition wire connector
in the boot may create arcing that could
ignite combustible fumes and cause a
fire.
WARNING
Check condition of drilling tool at regular
short intervals. If behavior of tool
changes, check immediately for
tightness or any signs of cracks in
particular.
WARNING
Wear gloves when handling or
performing maintenance on auger
drilling tools.
WARNING
Replace damaged drilling tools
immediately, even if they have only
superficial cracks. Never attempt to
repair damaged drilling tools.

WARNING
Do not operate your power tool if the
muffler is damaged, missing or modified.
An improperly maintained muffler will
increase the risk of fire and hearing loss.
Your muffler is equipped with a spark-
arresting screen to reduce the risk of
fire; never operate your power tool if the
screen is missing, damaged or clogged.
Remember that the risk of a brush or
forest fire is greater in hot or dry
weather.
In California, it is a violation of § 4442 or
§ 4443 of the Public Resources Code to
use or operate gasoline-powered tools
on forest-covered, brush-covered or
grass-covered land unless the engine's
exhaust system is equipped with a
complying spark arrester that is
maintained in effective working order.
The owner/operator of this product is
responsible for properly maintaining the
spark arrester. Other states or
governmental entities/agencies, such as
the U.S. Forest Service, may have
similar requirements. Contact your local
fire agency or forest service for the laws
or regulations relating to fire protection
requirements.
Tighten all nuts, bolts and screws except
the carburetor adjustment screws after
each use.
For any maintenance of the emission
control system please refer to the
maintenance chart and to the limited
warranty statement near the end of the
instruction manual.
Do not clean your machine with a
pressure washer. The solid jet of water
may damage parts of the machine.
Store your power tool in a dry and locked
location out of reach of children. Before
storing for longer than a few days,
always empty the fuel tank (see chapter
"Storing the Machine" in the instruction
manual).
