Risk of fire or explosion
Avoid damage to the power cable by

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
