3.5 Connecting a compressed-air tool
When the compressed-air module (1.11, Order No.
452 829, supplied ready with CTM 33 LE and
CTM 44 LE) is fitted, the automatic cut-in of the
appliance also operates in conjunction with
compressed-air tools.
We also recommend fitting of the VE supply unit
(Order No. 452 797).
The supply unit filters and oils the compressed air
and allows the air pressure to be regulated.
An IAS connecting piece (Order No. 454 757) is
available for connecting Festool compressed-air
tools with the IAS system.
To ensure trouble-free functioning of the automatic
cut-in, the operating pressure of the tool must be 6
bar. Make sure that the compressed-air tool is
switched off when plugging it in and unplugging it!

Application
A systainer can be fixed on the shelf (1.12) with the
two clamps (1.13).
Tools or accessories can also be stowed on the
shelf and in the storage compartments (1.6, not with
CTM 22).
A hose coupling (1.14, Order No. 487 072) can also
be plugged into the opening (1.10).
Alternatively, a hose clip (order No. 452 998) can
be fitted for coiling the suction hose.
The suction hose is connected to the tool from
above with the hose coupling.
The wheels can be blocked by the brakes (2.7),
thus preventing the vacuum cleaner from rolling
away unexpectedly.
The push handle (2.10, Order No. 452 921; supplied
ready with CTM 44 and CTM 55) makes the
vacuum cleaner easier to move.
Accessories (e.g. vacuum accessories) can be
fixed to the push handle batten (2.8).
An air blast is obtained by inserting a suction hose
in the blast opening (2.12).
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.
Warning: A filter bag must be used without
exception when evacuating noxious substances!
The filter element becomes damp after evacuating
liquids.
A damp filter element clogs up quickly 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
(Order No. 452 924).
When the maximum filling level is reached, a level
indicator (2.11) automatically interrupts extraction.
Warning: Do not evacuate combustible liquids! If
foam or liquid escapes, stop work immediately and
empty the dirt container (see 5.4).
N.B.: With wet operation, the volume flow monitor
acoustic warning may sound on account of
increased flow resistance. This does not impair
functional safety.
4.3 Volume flow monitoring
If the air speed in the suction hose drops below
20 m/s, an acoustic warning signal sounds for
safety reasons.
Possible causes and adjustments:
Cause
ð Adjustment
Suction force regulator (1.4) set to a too low value
ð Adjust suction force regulator to a higher value
Rotary knob (1.2) not adjusted to the connected
hose diameter
ð Adjust to correct hose diameter
Suction hose blocked or twisted
ð Remove blockage or twist
Filter bag full
ð Change filter bag
Filter element dirty
ð Change filter element
ð Only when operating without a filter bag: clean
filter element
Electronic monitoring system malfunctioning
ð Call Festool customer service for adjustment
Wet suction
ð Functional safety not impaired; no action
necessary
