Festool PN570789, PI570789 Fitting tool inserts, Repositioning the rotatable handle

–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-fit 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 fitted 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.

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 fitted 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 Stickfix 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 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 firmly 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)

7.1

7.2

7.3

7.4

• 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.

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 flats 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.
