ble fluids.
NOTICE
Vacuuming abrasive material (such as grit, stone
chips, etc.) causes the impeller wheel and impel‐
ler housing to wear at a rapid rate. This results in
a considerable loss of suction power. In such a
case you should contact your dealer. STIHL rec‐
ommends you have this work done by a STIHL
servicing dealer.
Take particular care when vacuuming wet leaves
since they may block the blower wheel and
elbow.
To clear a blockage in the machine:
– Switch off the machine and disconnect the
mains plug
– Remove the elbow and suction tube – see
"Assembling the Vacuum Shredder".
– Clean the elbow and blower housing.

While working
If the power cord is damaged, imme‐
diately disconnect the plug from the
power supply to avoid the risk of elec‐
trocution.
Avoid damage to the power supply cord. Do not
drive over it, pinch or tug it.
Never jerk the connecting cord to disconnect it
from the wall outlet. To unplug, grasp the plug,
not the cord.
The power cord and power plug must never be
touched with wet hands.
In case of imminent danger or in an emergency,
move the trigger/switch to STOP or 0 .
Your power tool is designed to be operated by
one person only. Do not allow other persons in
the work area.
Children, animals and bystanders must remain at
a distance.
To reduce the risk of injury from
thrown objects, do not allow any other
persons within 5 meters of your own
position.
This distance must also be maintained in relation
to objects (vehicles, window panes) – risk of
property damage!
Do not direct the air blast towards bystanders or
animals – the machine may eject small objects at
high speed – risk of injury!.

2 Safety Precautions and Working Techniques
When blow-sweeping and vacuum shredding (in
open ground and gardens), watch out for small
animals to avoid harming them.
Never leave a running machine unattended.
Walk slowly forwards as you work – observe the
nozzle outlet at all times – do not walk back‐
wards – risk of stumbling.
Keep the connecting cord behind the power tool
at all times – do not walk backwards – risk of
stumbling.
Hold your power tool in a normal, relaxed work‐
ing position. Make sure you always have good
balance and secure footing.
Take care in splippery conditions on slopes and
uneven ground.
Watch out for obstacles: Be careful of refuse,
tree stumps, roots and ditches which could
cause you to trip or stumble
Do not work on a ladder or in unstable locations.
Be particularly alert and cautious when wearing
hearing protection because your ability to hear
warnings (shouts, alarms, etc.) is restricted.
Work calmly and carefully – in daylight conditions
and only when visibility is good. Proceed with
caution, do not put others in danger.
Take breaks when you start getting tired or feel‐
ing fatigue – risk of accidents!
Static electricity may build-up while blow-sweep‐
ing large quantities of very dusty material and
suddenly discharge in certain unfavorable condi‐
tions (e.g. very dry work area).
Always wear a dust mask if dust is generated.
Vacuuming unsuitable materials may block the
impeller wheel. Switch off the unit immediately
and disconnect the plug from the power supply.
Then clear the blockage.
Never attempt to insert objects into the impeller
housing through the intake screen or the nozzle.
They may be expelled at very high speed by the
blower – risk of injury.
If there is a noticeable change in running behav‐
ior (e.g. higher vibrations), stop work and rectify
the cause of the problem.
If your power 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 – see also
"Before Starting Work". Make sure the safety
