!
Warning!
Never test the ignition system with
ignition wire boot removed from spark
plug or with unseated spark plug, since
uncontained sparking may cause a fire.
!
Warning!
Do not operate your clearing saw if the
muffler is damaged, missing or modified.
An improperly maintained muffler will
increase the risk of fire and hearing loss.
Never touch a hot muffler or burn will
result. If your muffler was equipped with
a spark-arresting screen to reduce the
risk of fire (e.g. in the USA, Canada and
Australia), never operate your clearing
saw if the screen is missing or damaged.
Do not modify or remove any part of the
muffler or spark arresting screen.
Remember that the risk of forest fires is
greater in hot or dry weather.
Keep cutting tool sharp. Tighten all nuts,
bolts and screws, except the carburetor
adjustment screws, after each use.
Additionally, the daily maintenance
schedule for your clearing saw set forth
in your STIHL Owner's Manual should
be strictly followed.
FS 500, FS 550
For any maintenance please refer to the
maintenance chart and to the warranty
statement near the end of this manual.
Store clearing saw in a dry, 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".

USING THE CUTTING TOOLS
For an illustration of the various cutting
tools and instructions on proper
mounting see the chapter "Mounting the
cutting tools" in your owner's manual.
Using the mowing heads
Do not use with mowing line longer than
the intended diameter. With a properly
mounted guard, the built-in cutter will
automatically adjust the line to its proper
length. Overly long lines can overload
the engine, resulting in damage to the
clutch mechanism and nearby parts.
