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 
To reduce the risk of 
injury to your eyes never 
operate your power tool 
unless wearing goggles 
or properly fitted protec-
tive glasses with 
adequate top and side 
protection complying with 
ANSI Z 87.1 (or your 
applicable national 
standard).
Power tool noise may 
damage your hearing. 
Wear sound barriers (ear 
plugs or ear mufflers) to 
protect your hearing. 
Continual and regular 
users should have their 
hearing checked 
regularly. 
Clothing must be sturdy 
and snug-fitting, but allow 
complete freedom of 
movement.
Avoid loose-fitting jack-
ets, scarfs, neckties, 
jewelry, flared or cuffed 
pants, unconfined long 
hair or anything that 
could become drawn into 
the air intake. Secure hair 
so it is above shoulder 
level.
Good footing is very 
important. Wear sturdy 
boots with nonslip soles. 
Steel-toed safety boots 
are recommended.
