General
Particular safety
precautions must be
taken when working with
the machine. The power
connection is a particular
source of danger.
Read all instructions
before using this
machine. The following
safety precautions must
be observed.
Before starting work, always check that
your vacuum cleaner is operating
correctly and is in good condition. Pay
special attention to the power cable and
plug.
The machine may only be used by duly
trained and authorized operators. The
machine must never be used by
adolescents.
Keep children, animals and bystanders
at a safe distance.
The machine may only be operated with
an undamaged filter element.
Never attempt to pick up
flammable materials (hot
ashes, inflammable
explosive dust, glowing
cigarettes, etc.) or
combustible liquids
(petrol, thinners, etc.).
The machine cannot be used to vacuum
physiologically harmful dust.
Risk of fire or explosion
Avoid damage to the power cable by
rolling over, crushing or pulling it.
Never pull the power cable to disconnect
the plug from the wall outlet. Always
grasp the plug, never the cable, to
unplug.
Inspect the power cable regularly for
signs of damage or ageing. Never use
the machine if the power cable is
damaged in any way – risk of
electrocution.
The main plug must be
disconnected
immediately if the power
cable is damaged –
electric shocks can kill.
Always remove the paper filter bag and
check correct operation of the float
before using the vacuum cleaner to pick
up liquids or wet materials. Always use
the filter element.
Stop work immediately and empty the
container if foam forms.
Never modify your vacuum cleaner in
any way, as this could be extremely
dangerous.
Only carry out the maintenance work
and repairs described in this manual.
Other work should be performed by your
STIHL servicing dealer.
Only use original replacement parts.
Always disconnect the plug from the
power supply (unplug it) before
performing any kind of work on the
machine.
The power cable may only be repaired
or replaced by authorized personnel.
All plugs and connectors for power
cables must at least be splash-proof.
The machine must be unplugged from
the power supply before cleaning or
servicing it and before replacing any
parts.
Never spray the upper part of the
vacuum cleaner with water: danger to
people, risk of short-circuiting.

Switch off the connected machine

The motor continues to run for a few
seconds after switching off in order to
empty the suction hose.
Vacuuming dry matter
Flammable materials must not be
vacuumed.
Always ensure that the filter bag has
been fitted in the container before
vacuuming dry materials. This makes it
easier to dispose of the vacuumed
material. Dry matter can also be
vacuumed without filter bag.
Vacuuming liquids
Flammable liquids must not be
vacuumed.
Always remove the paper filter bag and
check correct operation of the float
before vacuuming liquids. The float
interrupts the air stream when the
container is full. The filter element
should be replaced by a special
cartridge* if the vacuum unit is used
exclusively for wet vacuuming.
The filter element is damp after
vacuuming liquids. The filter
element may clog more quickly if dry
matter is vacuumed while it is still
damp. For this reason, the filter
element should be dried or replaced
by a dry filter element before
vacuuming dry matter.
