Warning!
Since a muffler with a catalytic converter
cools down less rapidly than
conventional mufflers, always set your
backpack blower 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 blower 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 instructions
Work carefully.
english / USA
The assistance of another person may
be needed in placing the unit on your
back after starting. In order to reduce the
risk of injury to the assistant from thrown
objects or from contact with fumes, the
engine should be kept at idle speed
during this brief period, and your
assistant should not stand in the area of
the outlet nozzle or exhaust. Otherwise,
the unit should be started and operated
without assistance.
Operate the blower under good visibility
and daylight conditions only.
!
Warning!
Your blower produces
poisonous exhaust fumes
as soon as the combus-
tible engine is running.
These gases (e.g. carbon
monoxide) may be color-
less and odorless.
To reduce the risk of serious or fatal
injury from breathing toxic fumes, never
start or run the blower indoors or in
poorly ventilated locations. Ensure
proper ventilation when working in
trenches or other confined areas.
Keep the space behind and beside the
engine clear at all times to allow for the
escape of hot and toxic exhaust fumes.
