Warning!
To reduce the risk of injury from loss
of control, be absolutely sure that the
cutting tool is clear of you and all other
obstructions and objects, including the
ground, because when the engine starts
at starting-throttle, engine speed will be
fast enough for the clutch to engage and
turn the cutting tool.
!
Warning!
When you pull the starter grip, don't
wrap the starter rope around your hand.
Do not allow the grip to snap back, but
guide the starter rope to rewind it
properly. Failure to follow this procedure
may result in injury to hand or fingers
and may damage the starter
mechanism.
With the engine running but at idle,
attach the trimmer to the spring hook of
your harness (see appropriate chapter
of this manual).

Catalytic converter
!
Warning!
Some STIHL trimmer
models are equipped with
a catalytic converter,
which is designed to
reduce the exhaust
emissions of the engine
by a chemical process in the muffler.
Due to this process, the muffler does not
cool down as rapidly as conventional
mufflers when the engine returns to idle
or is shut off. To reduce the risk of fire
and burn injuries, the following specific
safety precautions must be observed.
!
Warning!
Since a muffler with a catalytic converter
cools down less rapidly than conven-
tional mufflers, always set your trimmer
down in the upright position and never
locate it where the muffler is near dry
brush, grass, wood chips or other
combustible materials while it is still hot.
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!
To reduce the risk of fire or burn injury,
let the unit cool down before refueling
your trimmer after use.
!
Warning!
Never disassemble or modify your
muffler. The muffler could be damaged
and cause an increase in heat radiation
or sparks, thereby increasing the risk of
fire or burn injury. You may also
permanently damage the engine. Have
your muffler serviced and repaired by
your STIHL Servicing Dealer only.
!
Warning!
To reduce the risk of fire or burn injury,
keep the area around the muffler clean.
Remove all debris such as pine needles,
branches or leaves.
