– 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 extrac-

tor 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 

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 polyam-

ide brushes (replacement for worn origi-nals) 

• AH-RAS D 115 metal (484728): Pack of 1 metal 

brush (for use with spark-generating materi-

als) 

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 ro-

tary sander housing. 

The brush ring (6.2) can be adjusted by means of 

the additional rotatable handle (6.1). This makes 

it possi-ble to achieve an optimum setting for 

the working position used. Always turn the brush 

ring into the direc-tion 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 rea-

sons, therefore, a spark-trap (484733) must be 

fi tted between the extractor hood and the rotary 

sander.

 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 

motor when the spindle stop is pressed in. 

In case the pad should seize:
– Remove the brush insert. 
– Insert the special spanner (7.4) through the slot 

(7.2) and place on spanner fl ats of tool.

– Release the tool with the spindle stop pressed 

by turning the special spanner.

Please note: Always screw the sanding pad onto 

the drive spindle by hand. This will make it con-

siderably easier to remove it subsequently.
