Proper Clothing
WARNING
To reduce the risk of injury, the operator
should wear proper protective apparel.
WARNING
Be particularly alert and cautious when
wearing hearing protection because
your ability to hear warnings (shouts,
alarms, etc.) is restricted.
WARNING
To reduce the risk of injury when the
inhalation of dust cannot be
substantially controlled use an
appropriate respirator for the material
being blown. For more information see
the "Working conditions" section of
these Safety Precautions.
THE POWER TOOL
For illustrations and definitions of the
power tool parts see the chapter on
"Parts and Controls."
WARNING
Never modify this power tool in any way.
Only attachments supplied by STIHL or
expressly approved by STIHL for use
with the specific STIHL model are
authorized. Although certain
unauthorized attachments are useable
with STIHL power tools, their use may,
in fact, be extremely dangerous.
If this tool is subjected to unusually high
loads for which it was not designed (e.g.
heavy impact or a fall), always check
that it is in good condition before
continuing work. Check in particular that
the fuel system is tight (no leaks) and
that the controls and safety devices are
working properly. Do not continue
operating this machine if it is damaged.
In case of doubt, have it checked by your
STIHL servicing dealer.
WARNING
Small particles (e.g. dust) blown through
the blower tubes and nozzle can cause
a static charging of the blower tubes.
This is especially true in low humidity
and high dust conditions. In order to
reduce the risk of shock from static
charging and subsequent injury from
loss of control, your blower has features
designed to help reduce the build up of
static electricity in the blower tubes and
equalize the charge with the engine
and/or operator:
The control handle is designed to
conduct static electricity through the
throttle cable to the engine and from the
handle through the operator to the
ground.
STIHL offers an optional kit for use in
especially dry and dusty conditions. The
kit contains: (1) blower tubes made with
graphite to help conduct the charge back
to the control handle, and (2) a metal
ring with "wire" for insertion in the end
tube that helps reduce the buildup of
static electricity.
If your blower is properly assembled and
you are still experiencing static shocks,
make sure that your foot ware has
conductive soles and try operating your
