the power tool is used.
If the electric power tool is used for other ap-
plications, with other tools or is not maintained
sufficiently prior to operation, however, the vibra-
tion and noise load may be higher when the tool is
used. Take into account any machine idling times
and downtimes to estimate these values more
accurately for a specified time period. This may
significantly reduce the load during the machine
operating period.
3 Power supply and start-up
The mains voltage must correspond to
the specification on the rating plate.
Switch (1.1) serves as an On/Off switch (I = On / 0
= Off). It may be latched with the locking knob on
the side (1.2) for continuous operation. Pressing
the switch again releases the lock.
Always switch the machine off before
connecting or disconnecting the mains
lead!
See Fig. 3 for connection and disconnection of the
power cable.
4 Electronics
The RS 300 EQ has an electronic control
with which the rotational speed can be
varied step-free.
This allows the sanding speed to be adapted to
the optimum level according to the material con-
cerned (see Chapter 6).
The speed is set using the rotary control button
(2.1).
5 Dust extraction
Dust extractors prevent large accumu-
lations of dust in the air in the working
environment and dirt collecting at the
workplace.
5.1 Inboard extraction
The machines are fitted with inboard extraction as
standard. The sanding dust is extracted through
suction openings in the sanding base (2.4) and
trapped in the turbo-filter (1.5). The turbo-filter
has to be changed when it is so full of dust that
the extraction power diminishes.
Inserting a turbo-filter
- Push the front cardboard section of the turbo-
filter with the sealing lip (1.4) onto the extraction
nozzle (1.9) of the filter holder
- Insert rear cardboard section with slot (1.6) onto
the retaining strip (1.7) of the filter holder
- Push the filter holder with its opening (1.11) as
far as it will go onto the extraction nozzle (1.3)
of the machine and clamp tight by turning rotary
knob (1.10).
5.2 External extraction by an extraction
unit
In order to avoid frequent changing of the turbo-
filter when carrying longer sanding jobs, it is
possible to connect a Festool extractor to the unit
instead of using inboard extraction. In this case,
the extraction pipe (Ø 27 mm (1.8)) of the extrac-
tion unit is connected to the suction nozzle (1.3).
6 Special sanding pads
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.
6.1 Sanding pad STF-93x230
Please use the enclosed countersunk screws to
secure the STF-93x230 sanding pad instead of the
standard oval-head screws.
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 bot-
tom. 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.
6.2 Sanding pad STF-V93x266
The STF-V93x266 sanding pad is fastened with
standard oval-head screws.
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
