Vacuuming Dry Materials; Vacuuming Liquids - Festool CTM 22 E SG Notice D'utilisation D'origine

4.4 Emptying the dirt trap (2.10)
Always remove the upper part of the
vacuum cleaner before emptying the dirt
container!
- Open the vacuum cleaner,
- Raise the upper part slightly, depress the
support (2.5),
- Raise the upper part to the stop (vertical
position),
- Remove the upper part by moving it for-
wards horizontally,
- Empty the dirt container,
- Replace the upper part. Warning: Make
sure that both upper-part pins are fully
inserted in the recesses (1.5)!
- Close the vacuum cleaner.
4.5 Stand/Brake
The wheels can be blocked by the brakes
(2.8), thus preventing the vacuum cleaner
from rolling away unexpectedly.
4.6 Hose depot (partly in scope of
delivery)
Securing the hose depot on the dust extrac-
tor: see Fig. 4. When work is complete, you
can guide the extractor hose through the
opening (4.1) and deposit the hose in the
depot. Similarly, the mains cable can also
be guided through the opening (4.2) and
deposited in the hose depot.
5 Application
- A systainer can be fi xed to the storage
area (1.12) with the two clamps (1.10).
Tools or accessories can also be stowed
on the storage area and in the storage
compartments (1.6, not with CTM 22).
- A hose coupling (1.11) (487072) can be
plugged into the opening (1.8). The suc-
tion hose is connected to the tool from
above with the hose coupling. Alterna-
tively, a hose clip (452998) can be fi tted
for coiling the suction hose.
- The push handle (2.11) (452921; supplied
ready with CTM 44 and CTM 55) makes the
vacuum cleaner easier to move. Acces-
sories (e.g. vacuum accessories) can be
fi xed to the push handle batten (2.9).
- An air blast is obtained by inserting a suc-
tion hose in the blast opening (2.7).
5.1

Vacuuming dry materials

A fi lter bag must be used without
exception when evacuating noxious
substances!
Before using the vacuum cleaner to evacu-
ate dry substances, a fi lter bag must always
be inserted in the container.
Then the evacuated material can be dis-
posed of easily. The fi lter element becomes
damp after evacuating liquids. A damp fi lter
element suffers more wear and tear if it
is used for dry materials. Accordingly, the
fi lter element should be dried or replaced
with a dry one before dry operation.
5.2

Vacuuming liquids

Do not evacuate combustible liquids!
If foam or liquid escapes, stop work
immediately and empty the dirt con-
tainer.
The fi lter bag has to be removed before
evacuating liquids. We recommend use of a
special wet fi lter. When the maximum fi lling
level is reached, a bag-full indicator (2.12)
automatically interrupts extraction.
5.3 Volume fl ow 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
- Adjustment
Suction force regulator (1.4) set to a
too low value
- Adjust suction force regulator to a higher
value
Rotary knob (1.2) not adjusted to the
connected hose diameter
- Adjust to correct hose diameter
Suction hose blocked or twisted
- Remove blockage or twist
Filter bag full
- Change fi lter bag
Filter element dirty
- Change fi lter element
- Only when operating without a fi lter bag:
clean fi lter element
Electronic monitoring system malfunc-
tioning
- Call Festool customer service for adjust-
ment
