3 Operation
3.1 Changing the filter
During the following procedure, take care not
to raise dust more than is unavoidable.
a) Changing the filter bag
- Open locking clips (1.4), remove top section
(1.5),
- Change filter bag (2.1) ๎ see print on filter
bag,
- Replace top section, close locking clips.
Note: A replacement filter bag can be stored
in the storage compartment (5.4).
b) Changing the filter element
Do not operate machine without a filter
element.
This may damage the motor.
- Open locking clips (1.4), remove top section
(1.5),
- Fold over handle (3.2) and remove holder
(3.3),
- Remove used filter element (3.4) and replace
with a new one,
- Replace holder and fold over handle until it
latches into place,
- Replace top section, close locking clips.
3.2 Emptying the dirt trap
The dirt trap (2.2) can be emptied once the
top part has been removed.
3.3 Stand / Brake
Folding out the stand (4.5) prevents the mo-
bile dust extractor from rolling away.
To achieve this, lift the front end of the mobile
dust extractor slightly and push the stand
downwards until it latches into place.
Press the button to release the stand (4.4).
4 Application
The extractor hose (4.2) is connected to the
extractor opening by the angle bracket (4.1).
During machine operation, the extractor hose
is inserted through the opening (4.3).
A Systainer can be attached to the storage
area (5.6) via the four locking clips (5.5).
Note: The mains cable then has to be inserted
through the opening (5.3).
4.1 Vacuuming dry materials
Before using the vacuum cleaner to
evacuate dry substances, a filter bag
must always be inserted in the
container. Then the evacuated material
can be disposed off easily.
The filter element becomes damp after
evacuating liquids.
A damp filter element suffers more wear and
tear if it is used for dry materials.
Accordingly, the filter element should be dried
or replaced with a dry one before dry operation.
4.2 Vacuuming liquids
The filter bag has to be removed before
evacuating liquids. We recommend use
of a special wet filter.
When the maximum filling level is reached, a
level indicator (3.1) automatically interrupts
extraction.
Do not evacuate combustible liquids!
If foam or liquid escapes, stop work
immediately and empty the dirt
container.
4.3 The antistatic system (AS)
Friction in the suction hose causes electrostatic
charges which can result in unpleasant electric
shocks for the operator.
In order to conduct these static charges to
earth, the extraction units are provided with
an antistatic system as a standard feature.
However, antistatic hoses and accessories
have to be used in this case.
The antistatic function will only work if
the plug is plugged into a totally earthed
socket.
5 After finishing work
- Switch off the cleaner and pull the plug of the
mains lead out of the plug socket.
- Empty dirt tank.
- Insert the suction hose (5.1) and connecting
pipe (5.2) in the top section.
- Clean the vacuum cleaner inside and outside
by suction and wiping.
- Deposit the appliance in a dry room, safe from
unauthorised use.
6 Temperature control
A temperature fuse switches the dust extractor
off before this reaches a critical temperature
to protect against overheating - switch dust
extractor off and leave for around 5 minutes
to cool down.
If the dust extractor still cannot be switched
back on, please consult a Festool-service
centre.
