Inserting the safety filter bag [7]
► Insert a new safety filter bag (FIS-CTH
26/48) on the inlet nozzle of the container
and lock in position. Important: Ensure the
lock is snapped in.
► Place the plastic bag over the edge of the
container. The lateral openings on the safe­

dirt trap.
Ensure the contacts are [10-2]free.
Make sure that the filter bag is not pinched
between the top and bottom sections.
► Replace the top section [2-1] and close the
locking clips [2-2].
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 Solution
Value set on the suction power adjust­
er [1-9] is too low.
Set the suction power adjuster to a higher value (see
Chapter 7.4 ).
Rotary knob [1-8] not set to the correct
hose diameter.
Set the knob to the correct hose diameter (see Chap­
ter 7.1 ).
Suction hose blocked or kinked. Remove blockage or kink.
Filter bag full. Insert a new filter bag (see Chapter 7.7 ).
Dirty main filter. Changing the main filter (see Chapter 9.1 ).
Monitoring electronics malfunction. Send to a Festool service workshop for repair.
Wet extraction. Functional reliability not affected, no actions required.
8 Working
8.1 Handling
Hose holder: After finishing work, you can feed
the suction hose through the opening [8-2] and
place it in the hose holder.
SysDoc Systainer storage area: A Systainer can
be fastened to the storage area with the four
slides or the T-Loc lock [8-1].
8.2
Extracting dry materials
CAUTION
Hazardous dust
Damage to the respiratory passage
► Always use a safety filter bag and an ap­
propriate main filter when extracting haz­
ardous materials.
► Do not use the machine if the volumetric
flow monitoring function is inactive.
When extracting large quantities of oak
or beech wood dust or dust that exceeds
the permitted limit values, only extract from a
single machine (electric or air tool).
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 dis­
charged back into the room must not exceed
50% of the fresh air volume flow (room volume
V
R
x air renewal rate L
W
). Observe all the rele­
vant regional regulations.
Remember: A moist main filter clogs more
quickly when extracting dry materials. There­
fore, dry the main filter before extracting dust
or replace the damp filter with a dry one.
