7.9 Volumetric flow monitoring
An acoustic warning signal sounds if the air speed in the suction hose falls below 20 m/s.
Possible causes
Value set on the suction power adjuster
[1-9] is too low.
Rotary knob [1-8] not set to the correct
hose diameter.
Suction hose blocked or kinked.
Filter bag full.
Dirty main filter.
Monitoring electronics malfunction.
Wet extraction.

Working

8.1 Handling
Hose store: after finishing work, you can
feed the suction hose through the recess [8-
3] and place it in the hose store. You can do
the same with the mains cable through the
other recess [8-2].
SysDoc Systainer attachment system: a
Systainer can be attached to the storage
area via the two slides [8-1].
8.2 Extracting dry materials
CAUTION
Hazardous dust
Damage to the respiratory passage
X
Always use a safety filter bag when ex-
tracting hazardous materials!
X
Do not use the machine if the volumetric
flow monitoring function is inactive.
Observe the following when extracting
dust generated by operating electric power
tools:
If the exhaust air is discharged back into the
room, the air renewal rate L within the
room must be sufficient. The volume of air
discharged back into the room must not ex-
ceed 50% of the fresh air volume flow (room
volume V x air renewal rate L
R
the relevant regional regulations.

Solution
Set the suction power adjuster to a higher value
(see Chapter 7.4).
Set the knob to the correct hose diameter (see
Chapter 7.1).
Remove blockage or kink.
Insert a new filter bag (see Chapter 7.7).
Changing the main filter (see Chapter 9.1).
Send to a Festool service workshop for repair.
Functional reliability not affected, no actions
required.
Remember: A moist main filter clogs more
quickly
Therefore, dry the main filter before extract-
ing dust or replace the damp filter with a dry
one.
8.3
Before the absorption of liquids remove the
filter bag or safety filter bag (see Chapter
7.7, 7.8). The use of a special wet filter is
recommended.
The dust extractor stops automatically when
the maximum level is reached.

8.4
Friction inside the extraction hose causes
static electricity to develop during extraction.
Operating personnel may receive unpleasant
electric shocks while working. The mobile
dust extractor is fitted with an antistatic sys-
tem as standard to discharge any static elec-
tricity that may develop. However, always
use the enclosed antistatic extraction hose.
