Noise level
Measuring uncertainty allowance
The noise level can exceed 85 dB(A) during
operation. Wear ear protection!
Vibration emission level a
ured in accordance with EN ISO 8662:
Handle
Auxiliary handle
The emission values specifi ed (vibration, noise)
were measured in accordance with the test con-
ditions stipulated in EN ISO 15 744/EN ISO 8662
and are intended for machine comparisons. They
are also used for making preliminary estimates
regarding vibration and noise loads during opera-
tion. The emission values specifi ed refer to the
main applications for which the air tool is used.
If the air tool is used for other applications, with
other tools or is not maintained suffi ciently prior
to operation, however, the vibration and noise load
may be higher when the tool is used. Take into ac-
count any machine idling times and downtimes to
estimate these values more accurately for a speci-
fi ed time period. This may signifi cantly reduce the
load during the machine operating period.
4 Compressed-air supply and commis-
sioning
Make sure that the pneumatic tool is
switched off when you connect the com-
pressed-air supply.
4.1

Compressed-air processing

The Festool service unit VE should always be used
to ensure that Festool pneumatic tools function
correctly. Consisting of a fi lter, control unit, con-
densation drain and lubricator, the service unit
cleans and lubricates the compressed air and
keeps it free of condensation. Here, the lubrica-
tor should be set so that a drop is applied to the
compressed air approx. every 7-10 minutes.
Damage that occurs as a result of in-
correct compressed-air processing is
excluded from warranty claims.
We recommend a service unit with a 3/8" connector,
when up to two Festool pneumatic tools are used.
A compressor that supplies at 500 l/min and at
an operating pressure of 6 bar should be used to
supply compressed-air. The diameter of the piping
system must be suffi ciently large (at least 9 mm).

4.2 IAS 2 hose connector
The sander is a pneumatic tool for connection to
the Festool IAS 2 system. This hose system com-
bines three functions in one hose:
- Compressed air supply [3-1]
- Exhaust air extraction [3-2]

- Dust extraction [3-3]

Connection and disconnection – see Fig. 2.
4.3 Commissioning
Switch [1-1] serves as an On/Off switch (I = On /
0 = Off).
5 Machine settings
The machine should always be discon-
nected from the compressed air supply
before any work is carried out on the
machine.
5.1

Speed adjustment

You can regulate the speed steplessly between 5,500
and 7,000 min-1 using the adjusting wheel [1-2].
This enables you to optimise the cutting speed to
suit the material.
5.2 Dust extraction
The sanding dust is extracted directly
through the extraction channels in the
sanding shoe directly at the point of sand-
ing.
To guarantee optimized dust extraction, we rec-
ommend using Festool extractors with automatic
switch-on/switch-off device for compressed-air
machines.
5.3

Attaching sanding material

Self-adhesive abrasives such as Stickfi x
sandpaper and sanding fl eeces can be
attached to Stickfi x sanding shoes.
The abrasives are simply pressed onto the sanding
shoe [1-3] and pulled off after use.
Always use original Festool sanding ma-
terials!
Use only sanding shoes with undamaged Velcro
coatings.
6 Maintenance and care
The machine should always be discon-
nected from the compressed air supply
before any work is carried out on the
machine.
