Warning!
To reduce the risk of fire and burn injury,
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!
Never modify your muffler. The muffler
could be damaged and cause an
increase in heat radiation or sparks,
thereby increasing the risk of fire and
burn injury. You may also permanently
damage the engine. Have your muffler
serviced and repaired by your STIHL
servicing dealer only.
Catalytic converter
!
Warning!
Some STIHL power tools
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 power
tool 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.
!
Warning!
An improperly mounted or damaged
cylinder housing or a damaged/
deformed muffler shell may interfere
with the cooling process 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.
Reactive forces
!
Warning!
Reactive forces may occur any time the
chain is rotating.The force used to cut
wood can be reversed and work against
the operator. If the rotating chain is
suddenly stopped by contact with any
solid object such as a branch or is
pinched, the reactive forces may occur
instantly. These reactive forces may
result in loss of control, which, in turn,
may cause personal injury. An
understanding of the causes of these
reactive forces may help you avoid the
element of surprise and loss of control.
Because of the design of the pole
pruner, the reactive forces experienced
when working with it are generally not as
severe as those encountered with a
chainsaw. Nevertheless, you should
always maintain a proper grip and good
footing to control the power tool when
you experience such forces.
