Vacuuming Dry Materials; Vacuuming Liquids - Festool CTM 44 E Manual De Instrucciones

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).
- A hose coupling (1.11) (487072) can be plugged
into the opening (1.8). The suction hose is con-
nected to the tool from above with the hose
coupling. Alternatively, a hose clip (452998) can
be fi tted for coiling the suction hose.
- The push handle (2.11) (452921) makes the
vacuum cleaner easier to move. Accessories
(e.g. vacuum accessories) can be fi xed to the
push handle batten (2.9).
- An air blast is obtained by inserting a suction
hose in the blast opening (2.7).
5.1

Vacuuming dry materials

A fi lter bag must be used without excep-
tion when evacuating noxious substanc-
es!
Before using the vacuum cleaner to evacuate dry
substances, a fi lter bag must always be inserted
in the container.
Then the evacuated material can be disposed 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 im-
mediately and empty the dirt container.
The fi lter bag has to be removed before evacuat-
ing 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 malfunctioning
- Call Festool customer service for adjustment
Wet suction
- Functional safety not impaired; no action neces-
sary
6 After fi nishing work
- Switch off the cleaner and pull the Plug of the
mains lead out of the Plug socket.
- Wind up the mains lead (2.6).
- Empty dirt tank.
- Clean the vacuum cleaner inside and outside by
suction and wiping.
- Deposit the appliance in a dry room, safe from
unauthorised use.
7 Maintenance and care
Always remove the power supply plug
from the socket before carrying out any
work on the machine.
All maintenance and repair work which
requires the motor casing to be opened
may only be carried out by an authorised
service centre.
A safety test is to be carried out at least once a
year by the manufacturer or an instructed person,
e.g. for possible damage to the fi lter and leaks
in the appliance, and to ensure that the control
devices are functioning.
If the user services the appliance, it must be dis-
mantled, cleaned and serviced, as far as possible
without any danger to the maintenance staff and
other persons. Appropriate measures include
decontamination before dismantling, locally fi l-
tered forced ventilation on the dismantling site,
cleaning the service area, and suitable personal
safety equipment.
