English 5 IMPORTANT SAFETY INSTRUCTIONS
￭ Although certain unauthorized attachments may fit your
STIHL chain saw, their use may be extremely dangerous.
Only attachments supplied by STIHL or expressly
approved by STIHL for use with this specific model are
recommended.
– Use only attachments supplied or expressly
approved by STIHL.
– Never modify this chain saw in any way.
– Never attempt to modify or override the chain saw's
controls or safety devices in any way.
– Never use a chain saw that has been modified or
altered from its original design.
￭ Any modification to your muffler or spark arresting screen
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.
– Never modify your muffler or spark arresting screen.
￭ If the chain saw is dropped or subjected to similar heavy
impacts:
– Check that it is undamaged, in good condition and
functioning properly before continuing work.
– Check that the fuel system is tight and has no leaks.
– Check that the controls and safety devices, including
the chain brake, are working properly, @ 17.
– Never work with a damaged or malfunctioning chain
saw. In case of doubt, have the chain saw checked
by your authorized STIHL servicing dealer.
￭ Genuine STIHL replacement parts are specifically
designed to match your chain saw and meet safety and
performance requirements. Use of parts that are not
authorized or approved by STIHL may cause serious or
fatal injury or property damage.
– STIHL recommends that only identical STIHL
replacement parts be used.
5.5 Fueling Instructions
Fuel
WARNING
￭ Gasoline and its vapors are extremely flammable. Your
STIHL chain saw uses an oil-gasoline mixture for fuel. If
spilled and ignited by a spark or other ignition source, it
can cause fire and serious burn injury or property damage.
Pick a Safe Location for Fueling
WARNING
￭ To reduce the risk of fire and explosion while fueling:
– Use extreme caution when handling
gasoline or fuel mix.
– Do not smoke or bring any fire or flame
near the fuel or the chain saw.
– Note that combustible fuel vapor may
escape from the fuel system.
– Fuel your chain saw in a well-ventilated
area, outdoors away from flames, pilot
lights, heaters, electric motors, and other
sources of ignition. Vapors can be
ignited by a spark or flame many feet
away.
– Select bare ground for fueling and move
at least 10 ft. (3 m) from the fueling spot
before starting the engine.
– Wipe off any spilled fuel before starting
your chain saw.
– Take care not to get fuel on your
clothing. If this happens, change your
clothing immediately.
