- The appliance may be operated only in an
adequately ventilated space (in compliance
with national industrial safety provisions).
- Do not suck in any sparks or hot chippings.
- With the exception of wood dust, do not
suck in any fl ammable or explosive dusts
such as magnesium, aluminium etc. - Risk
of explosion!
- Do not use to extract fl ammable or explo-
sive liquids (e.g. petrol, thinners) - Risk
of explosion!
- Do not use to extract aggressive liquids/
dry materials (e.g. acids, alkalis, solvents).
- Remove plug from mains socket when not
in use and before maintenance work.
- Do not pull plug out of mains socket by
its cable.
- Protect the cable against heat, oil and
sharp edges.
- Check the plugs and cables regularly and
have them replaced by an expert if damaged.
- Do not leave devices out in the rain.
- Do not lift or carry the devices by their
handles using a crane hook or lifting gear.
- The device may only be used by persons
who have been trained in its use and who
are authorised to do so.
- If noxious dusts have been extracted, the
vacuum cleaner and all accessories must
be completely cleaned (inside and outside)
by suction and wiping, before removal
from the contaminated area. Parts that
cannot be completely cleaned are to be
packed for transport in a plastic bag with
an airtight seal.
- For safety reasons, only operate the ma-
chine using a totally earthed socket.
3 Appliance preparation and initial
operation
The accessories are delivered horizontal in
the container (2.10), and must be removed
prior to initial operation.
3.1 Power supply
The line voltage and frequency must
correspond with the data on the rat-
ings plate!
Make sure that the vacuum cleaner is switched
off when you plug the power cable in.
The antistatic system (AS)
Friction in the suction hose causes electro-
static charges which can result in unpleas-
ant 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.
3.2 On/off switch (1.3)
In position 0 the vacuum cleaner is switched
off and the appliance plug socket (1.2) is dead.
Two modes of operation are possible:
a) Switch position „MAN“
The appliance plug socket is dead.
The cleaner motor starts immediately.
b) Switch position „Auto“
The appliance plug socket is live.
Before turning the switch to the
„Auto“ position, ensure that the
tool connected to the appliance plug
socket is switched off.
The cleaner motor starts only when the tool
connected to the appliance plug socket is
switched on.
3.3 Suction force regulator (1.4)
The suction force regulator can be used to
vary the suction capacity. This permits a
precise adaptation to different substances
to be picked up.
3.4 Temperature control
A temperature fuse switches the dust ex-
tractor off before this reaches a critical
temperature to protect against overheat-
ing - 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.
3.5 Connecting an electric tool
Observe the maximum connected
load on the appliance plug socket
(see “Technical Data“)!
Make sure that the electric tool is
switched off when plugging it in and
unplugging it.
Connect the electric tool to the appliance
plug socket (1.2).
3.6 Connecting pneumatic tools
Make sure that the pneumatic tool
is switched off when plugging it in
and unplugging it.
When the compressed-air module (1.8)
(452829; supplied ready with CTL 33 LE
SG and CTL 44 LE) is fi tted, the automatic
