4.2 External extraction by an extraction
unit
In order to avoid frequent changing of the tur-
bo-filter when carrying longer sanding jobs, it
is possible to connect a Festool extractor to
the unit instead of using inbuilt extraction.
In this case, the extraction pipe (Ø 27 mm
(1.8)) of the extraction unit is connected to
the suction nozzle (1.3).
5 Special sanding pad
The standard sanding pad (93 x 175 mm) can
be exchanged for a special sanding pad. Loosen
the four fastening screws (2.2).
The special sanding shoe is mounted in such a
way that the extended side protrudes over the
front edge of the sander.
Please use the enclosed countersunk screws
to secure the STF 93 x 230 sanding pad instead
of the standard oval-head screws.
5.1 Sanding pad STF 93 x 230
The special application of this sanding pad is to
sand in narrow spaces, e.g. between the
louvers on folding shutters or behind heating
pipes.
The protruding part of the sanding pad is 60 mm
long and has a Stickfix coating on the top and
bottom.
Stickfix sandpaper rolls in grit sizes P 50 to
P 180 are available for these applications.
These rolls are 12 m long and can be cut to
the desired length by the customer.
Cut through the Stickfix adhesive coating on
the back and the carrier material using a sharp
knife.
The sandpaper can then be simply torn off.
Please note that this sanding pad cannot be
used in conjunction with a suction unit.
Please secure with the enclosed countersunk
screws instead of the standard oval-head
screws.
5.2 Sanding pad STF 93V x 266
This sanding pad has a protruding triangular
point with an edge length of 93 mm it was
developed for sanding in corners and edges
though can also be used on flat surfaces thanks
to its continuous Stickfix coating.
Affix the triangular abrasive STF 93V to the tip
followed directly by a normal sanding strip STF
93 x 178.
In order to obtain maximum use of the
triangular abrasive it can be rotated at random
on the end of the sanding pad.
The STF 93V x 266 sanding pad is fastened
with standard oval-head screws.
Please note: The STF 93V x 266 sanding pad
has been specially developed for work in
corners and on edges.
Experience has shown that this leads to uneven
stress on the tip of the sanding pad.
This inevitably leads to the generation of more
heat than when working on flat surfaces since
the same force has to be distributed over a
smaller surface.
You should therefore work with reduced
pressure, otherwise the Stickfix coating on the
sanding pad and abrasive can become
damaged.
6 Attaching sanding material
6.1 Stickfix abrasives
The appropriate Stickfix sanding paper and
Stickfix sanding felt can be fastened quickly and
easily onto the Stickfix sanding base.
Always use original Festool sanding materials!
The self-adhesive sanding material (2.3) is
simply pressed onto the sanding base (2.4)
and held safely in place by the Stickfix sanding
base velcro surface.
6.2 Clamped sandpaper
Start clamping the abrasive on the back of the
tool by raising the clamping lever (1.12) and
thus opening the clamping device.
Insert abrasive up to limit stop and lower
clamping lever into initial position.
Place the abrasive on the sanding pad, pull
taught and clamp on the front.
Not perforated abrasives can be perforated by
the Festool Lochfix.
7 Operating instructions
Never overload the tool by using too
much pressure!
The best sanding results are achieved when
applying moderate pressure.
The sanding performance and quality depend
mainly on the choice of the right sanding
material.
Festool offers the appropriate sanding material
for all applications (see Festool catalogue).
We recommend the following settings on the
rotary control (2.1) for electronic machines:
rotary control setting
- sanding work
5 - 6
- sanding with max. drive
- sanding old paint
- sanding wood and veneer prior to painting
- interim sanding of paint on surfaces
4 - 5
- sanding of thinly applied primer
- sanding of wood with sanding vlies
- sanding edges on wooden parts
- smoothing primed wooden surfaces.
