– are used to compare machines.
– They are also used for making preliminary esti-
mates regarding vibration and noise loads during
operation.
– They represent the primary applications of the

5 Compressed-air supply and com-
missioning
CAUTION
Risk of injury

Make sure that the pneumatic tool is switched
off when you connect the compressed-air sup-
ply.
5.1

Compressed-air processing

The Festool service unit should always be used to
ensure that Festool pneumatic tools function cor-
rectly. Consisting of a filter, control unit, condensa-
tion drain and lubricator, the service unit cleans and
lubricates the compressed air and keeps it free of
condensation. Here, the lubricator 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 incorrect com-
pressed-air processing is excluded from warranty
claims.
 We recommend a service unit with a 3/8" con-
nector, 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 sup-
ply compressed-air.
The diameter of the piping system must be suffi-
ciently large (at least 9 mm).
5.2

IAS 3 hose connector

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

• Dust extraction [1-3]

Connection and disconnection - see Fig. [5].
5.3

Switch on/off

Pressing the lever [2-1] switches on the com-
pressed-air tool. Releasing the lever switches the
machine off again.

CAUTION
Risk of injury

The machine should always be disconnected
from the compressed air supply before any work
is carried out on the machine.
6.1 Electronics
Speed adjustment
You can regulate the rotational speed steplessly be-
tween 4000 - 7000 rpm using the adjusting wheel
[2-2].
This enables you to optimise the cutting speed to
suit the material.
6.2

Attaching sanding accessories

You can choose between 2 types of abrasive fasten-
ing for the compressed-air orbital sanders LRS 93
M and LRS 93 G:
Clamping abrasive

Start at the rear.

Open the clamping device [4-1] by pressing the
locking lever.

Insert abrasive up to stop [4-2] and release le-
ver.

Then apply abrasive onto sanding pad, pull tight
and clamp with the front lever.
Fasten abrasive with StickFix
The suitable StickFix sandpaper and StickFix sand-
ing cloth can be attached quickly and simply to the
StickFix sanding pad.

Press the self-adhesive sanding accessory onto
the sanding pad .
6.3 Dust extraction
WARNING
Dust hazard

Dust can be hazardous to health. Always work
with a dust extractor.

Always read applicable national regulations be-
fore extracting hazardous dust.
To guarantee optimal dust extraction, we recom-
mend using Festool extractors with automatic
switch-on/switch-off device for compressed air
machines.
