removed. To reduce the risk of personal 
injury, do not operate a chain saw with a 
damaged or missing chain catcher.
WARNING
Inspect antivibration elements 
periodically. Replace damaged, broken 
or excessively worn antivibration 
elements immediately, since they may 
result in loss of control of the saw. A 
"sponginess" in the feel of the saw, 
increased vibration or increased 
"bottoming" during normal operation 
may indicate damage, breakage or 
excessive wear. Antivibration elements 
should always be replaced in sets. If you 
have any questions as to whether the 
antivibration elements should be 
replaced, consult your STIHL servicing 
dealer.
If this chain saw is subjected to 
unusually high loads for which it was not 
designed (e. g. heavy impact or a fall), 
always check that it is in good condition 
before continuing work. Check in 
particular that the fuel system is tight (no 
leaks) and that the controls and safety 
devices are working properly. Do not 
continue operating this chain saw if it is 
damaged. In case of doubt, have it 
checked by your STIHL servicing dealer.
Your chain saw is not designed for 
prying or shoveling away limbs, roots or 
other objects. Such use could damage 
the cutting attachment or AV system.
WARNING
When sawing, make sure that the saw 
chain does not touch any foreign 
materials such as rocks, fences, nails 
and the like. Such objects may be flung 
off, damage the saw chain or cause the 
chain saw to kickback.
WARNING
If the rotating saw chain strikes a rock or 
other hard object, sparks may be 
created, which can ignite flammabale 
materials under certain circumstances. 
Flammable materials can include dry 
vegetation and brush, particularly when 
weather conditions are hot and dry. Do 
not use your chain saw around 
flammable materials or around dry 
vegetation or brush when there is a risk 
of fire or wildfire. Contact your local fire 
authorities or the U.S. Forestry Service if 
you have any question about whether 
vegetation and weather conditions are 
suitable for the use of a chain saw.
WARNING
Take special care when cutting 
shattered wood because of the risk of 
injury from slivers being caught and 
thrown in your direction.
WARNING
Never modify your muffler. Any 
modification could cause an increase in 
heat radiation, sparks or sound level, 
thereby increasing the risk of fire, burn 
injury or hearing loss. You may also 
permanently damage the engine. Have 
your muffler serviced and repaired by 
your STIHL servicing dealer only.
WARNING
The muffler and other parts of the engine 
(e.g. fins of the cylinder, spark plug) 
become hot during operation and remain 
hot for a while after stopping the engine. 
To reduce risk of burns, do not touch the 
muffler and other parts while they are 
hot. Keep the area around the muffler 
clean. Remove excess lubricant and all 
debris such as pine needles, branches 
or leaves. Let the engine cool down 
sitting on concrete, metal, bare ground 
or solid wood (e.g. the trunk of a felled 
tree) away from any combustible 
substances.
WARNING
An improperly mounted or damaged 
cylinder housing or a 
damaged/deformed muffler shell may 
interfere with the cooling process of the 
muffler. To reduce the risk of fire or burn 
injury, do not continue work with a 
damaged or improperly mounted 
cylinder housing or a 
damaged/deformed muffler shell.
Your muffler is furnished with a spark 
arresting screen designed to reduce the 
risk of fire from the emission of hot 
particles. Never operate your unit with a 
missing or damaged spark arresting 
screen. If your gas/oil mix ratio is correct 
(i.e., not too rich), this screen will 
normally stay clean as a result of the 
heat from the muffler and need no 
service or maintenance. If you 
experience loss of performance and you 
suspect a clogged screen, have your 
muffler maintained by a STIHL servicing 
dealer. Some state or federal laws or 
regulations may require a properly 
maintained spark arrester for certain 
uses. See the "Maintenance, Repair and 
Storing" section of these Safety 
Precautions. Remember that the risk of 
a brush or forest fire is greater in hot or 
dry conditions.
