WARNING
Use only identical STIHL replacement 
parts for maintenance and repair. Use of 
non-STIHL parts may cause serious or 
fatal injury.
Strictly follow the maintenance and 
repair instructions in the appropriate 
section of your KombiEngine and 
KombiTool instruction manuals. Please 
refer to the maintenance charts 
respectively the maintenance notes in 
these manuals.
WARNING
Always stop the engine and make sure 
that the working tool is stopped before 
doing any maintenance or repair work or 
cleaning the power tool. Do not attempt 
any maintenance or repair work not 
described in your KombiEngine and 
KombiTool instruction manuals. Have 
such work performed by your STIHL 
servicing dealer only.
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 attached.) A loose 
connection between spark plug boot and 
the ignition wire connector in the boot 
may create arcing that could ignite 
combustible fumes and cause a fire.
WARNING
Never test the ignition system with the 
ignition wire boot removed from the 
spark plug or with a removed spark plug, 
since uncontained sparking may cause 
a fire.
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.
Store the power tool in a dry and high or 
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 this 
manual.
