English / USA
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 hedge cutter 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.

!
Warning!
An improperly mounted or damaged
cylinder housing or a damaged/
deformed muffler shell may interfere
with the cooling effect of the catalytic
converter. 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 catalytic
converter is furnished with screens
designed to reduce the risk of fire from
the emission of hot particles. Due to the
heat from the catalytic reaction, these
screens will normally stay clean 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.
Working Conditions
Do not operate using the starting throttle
lock as you do not have control of the
engine speed. See section of your
owner's manual on the proper use of the
slide control.
!
Warning!
Your hedge cutter pro-
duces poisonous exhaust
fumes as soon as the
combustible engine is
running.
These gases (e.g. carbon monoxide)
may be colorless and odorless.
To reduce the risk of injury from
inhalation of poisonous fumes, start and
operate your hedge cutter only outdoors
in a well ventilated area. Hold your
hedge cutter in such a way that you do
not breath in the exaust fumes.
Operate the hedge cutter under good
visibility and daylight conditions only.
!
Warning!
Make sure you always have good
footing. Take particular care in slippery
conditions and on slopes. Be careful on
un-even ground. Watch out for stumps,
roots, ditches or holes which could
cause you to trip or stumble.
