the rotary sander and secure the hood by moving
the clamping lever forward (3.3).
4.1
4.2
4.5
4.4
4.3
Do not work with the machine unless the extractor
hood is clamped fi rmly and securely to the clamp-
ing throat. If the clamping force is reduced as the
result of frequent use, the clamping lever can be
re-adjusted.
–
Release the screw (4.1) on the clamping lever and
remove the lever (4.2).
–
Tighten the square-headed screw (4.3) by hand
until a tension is obtained.
–
Re-fi t the clamping lever and secure it with the
screw. The optimum clamping force can be de-
termined by closing the clamping lever before the
clamping screw is tightened.
b) Repositioning the rotatable handle
The rotatable additional handle can, if required, also
be fi tted to the right-hand side of the extractor hood.
For this purpose, the handle and the clamping lever
should be interchanged.
–
Release the screw (4.1) on the clamping lever and
remove the lever (4.2).
–
Remove the square-headed screw (4.3).
–
Detach the additional handle (4.5), using a 6 mm
A/F Allen key.
The clamping lever and the additional handle can
now be interchanged. Fitting is carried out in the
reverse of the above sequence. The locking nut
(4.4) can be used to vary the turning resistance of
the rotatable additional handle by tightening the
nut against the housing, using a 13 mm A/F open-
ended wrench, before fully tightening the additional
handle.
c) Replacing the brush insert
5.1
5.2
In order to replace this, press out the brush insert
by inserting a screwdriver through the square ap-
ertures (5.1). Insert the new brush strip (5.2) into
the groove, slightly bend this to obtain the correct
radius and press in fi rmly until the brush strip is in
contact with the base of the hood. The inclination of
the brush bristles must point outwards.
Two different brush inserts are available:
• AH-RAS D 115 Poly (484727): Pack of 2 polyamide
brushes (replacement for worn originals)
• AH-RAS D 115 metal (484728): Pack of 1 metal
brush (for use with spark-generating materials)
d) Sanding with dust extraction
For dust extraction, the suction hose (27 mm dia.)
of a Festool dust extractor should be inserted into
the connection socket (6.3) at the end of the rotary
sander housing.
The brush ring (6.2) can be adjusted by means of
the additional rotatable handle (6.1). This makes
it possible to achieve an optimum setting for the
working position used. Always turn the brush ring
into the direction of travel of the sanding dust.
A considerable quantity of air-borne sparks are
generated during the sanding of metals and other
spark-generating materials. For safety reasons,
therefore, a spark-trap (484733) must be fi tted
between the extractor hood and the rotary sander.

Fitting tool inserts
Use only tool inserts whose maximum
permissible speed is at least equal to the speed
given on the rating plate of the rotary sander. This
is the case with all original Festool accessories.
The Stickfi x sanding pads STF D 115 are provided
with an M 14 thread which enables these to be
screwed directly onto the drive spindle.
It is normally possible to unscrew the sanding pad
(7.3) by hand from the drive spindle after pressing
the spindle stop (7.1).
Actuate the spindle stop only when the
drive spindle is stationary. Do not switch on the mo-
tor when the spindle stop is pressed in.
