Dust Extraction - Festool BS 105 Manual De Instrucciones

- Switch on the machine and check that the sand-
ing belt is running smoothly. The sanding belt
must run centrally across the sanding base (3.4).
If this is not the case, use the rotary knob (3.1)
to adjust the position of the sanding belt.

Dust extraction

Always connect the machine to a dust
extractor when performing work that
generates dust.
Inboard extraction
Slide the connector (4.3) on the dust bag (4.1) onto
the extractor opening (4.2) and turn clockwise to
secure.
Make sure that the plate springs (4.5) touch the
belt casing on the machine.
Turn the connector anticlockwise to remove and
empty the bag.
External extraction by an extraction unit
Attach the adapter (4.4) to the extractor opening
(4.2) instead of the dust bag.
A Festool dust extractor with an extractor hose
diameter of 36 mm or 27 mm can be connected
to the adapter.
4.4 Cooling air
Position the air guide flap (1.1) so that the escap-
ing air does not disturb you.
5 Working with the machine
- Only switch off the machine when lifted from the
workpiece.
- Only guide the machine along the workpiece
when switched on. Only switch off the machine
once you have lifted it off the workpiece com-
pletely.
- Before putting the machine down, always switch
it off and wait until it has stopped completely.
- Always secure the workpiece in such a manner
that it cannot move while being sawed.
- The machine must always be held with both
hands by the designated handles (1.4, 1.5).
Operating instructions
Apply minimal pressure when working with the
machine. The weight of the machine should be
sufficient.
Work at a steady pace. Guide the machine in
parallel, overlapping sanding strokes along the
workpiece. Sand in the direction of the grain to
achieve a better surface quality.
When sanding paint, clean the workpiece surface
regularly so that paint dust does not clog the
sanding belt.
5.1 Stationary use (partly accessories)
CAUTION
Wear protective gloves!
During stationary use, the abrasive belt is
exposed and may cause grazes and cuts.
- Attach both feet (5.1) via the two threaded holes
(4.6). Important: the straight edges of the feet
must face inwards.
- Make sure that the machine is standing firmly:
use clamps to attach the feet to the base.
- Do not work with oversized and heavy work-
pieces that could damage the tool.
5.2 Sanding frame (partly accessories)
Assembly
- Position the machine so that the sanding frame
tenons (2.3) rest in the grooves (2.4). The coun-
terpiece (2.2) on the height adjuster must rest
underneath the spring (2.1).
- Push the machine downwards towards the
grooves (2.4) until the counterpiece (2.2) latches
into position.
Removal
- Push the knurled screw (2.7) downwards until
the counterpiece (2.2) pops out of the notch.
- Remove the machine from the sanding frame.
Note: the position of the sanding frame guide
elements (2.4) is set in the factory. Do not detach
them from the machine!
Working with the sanding frame
Adjust the height of the sanding frame using the
knurled screw (2.7). Increase the cutting depth
(the distance the sanding belt protrudes over the
edge of the sanding frame) by turning the screw
in the direction of the plus sign. One turn of the
knurled screw corresponds to 0.4 mm.
Practical hint: use a test workpiece to set the
sanding frame to the correct cutting depth.
When work is complete, push the eccentric clamp
(2.6) towards the machine until it latches into
position. The machine is raised above the work-
piece. When you return the eccentric clamp to its
original position, the preset cutting depth is the
same as before.
