12. Changing the saw blade

Your saw is equipped with a carbide-tipped saw blade with
24 teeth and an 80 mm diameter ex works.
This is very well suited for most „sawing jobs", guarantees
clean cuts in the most various materials and guarantees long
service life. But it will not last for ever, of course: Wear will
occur depending on the intensity of use: The saw blade will
become dull, more force to push the work piece is required
and the quality of the cut is reduced, the mechanics of the
machine are stressed more strongly than necessary.
Then it is high time to replace the saw blade with a new one.
It can also be necessary to use a different saw blade type for
a particular task (see also the chapter „Choosing the right
saw blade" below) so that it needs to be exchanged for the
standard blade. The work steps remain the same, naturally.
1. Disconnect the mains plug!
2. Turn the saw blade down as described in the chapter
„Height adjustment of the saw blade".
3. Swing open the housing as described in section 6.2
4. To release the screw 1 (fig 16a), the shaft on which the
saw blade 2 is mounted must be blocked. To do so, insert
the smaller of the two included Allen keys 3 through the
small drill hole 4 in the saw table and from there insert it
into the saw blade shaft through a cross-hole, see fig.
16b. If necessary, this drill hole must be „found" somewhat
by turning the saw blade by hand. A hint: For this proce-
dure we recommend you adjust the saw blade to a rela-
tively high height and then to lower it somewhat after find-
ing the latching drill hole with inserted Allen key in order to
gain full access to screw 1.
5. Release the cheese-head screw 1 with the larger of the
two Allen keys and remove together with disc 5.
The teeth of even worn saw blades are still very sharp! Risk
of injury!
6. Remove the old saw blade upwards and through the saw
blade opening and place the new saw blade on the shaft.
Make sure the saw blade drill hole is seated correctly at
the shaft shoulder!
7. Please also make sure that the teeth are pointing in the
direction as shown in the figures!
8. Screw on disc 5 with the cheese-head screw 1 and tight-
en. Note that the saw shaft still needs to remain blocked
with the small Allen key.
9. Release the latch, push down the upper housing part and
lock with the knurled screw.

12.1. Choosing the right saw blade

When choosing the saw blade, make sure at all costs that
the highest permissible speed is sufficiently high enough for
the idling speed of the saw!
Only use original Proxxon saw blades.
The choice of the suitable saw blade has an enormous
impact on the work result: Various characteristics such as
work piece material, saw job intensity and the desired quality
of the result must be considered. Proxxon has different saw
blades that can be used to operate the machine.

13. Maintenance and repairs:

Always disconnect the mains plug before doing any cleaning,
setting, maintenance or repair works!
The device is maintenance-free apart from the necessity of
regular cleaning (see below).
Only have repairs carried out by qualified specialist person-
nel or, even better, by the PROXXON central service. Never
repair electrical parts, but always exchange them for original
spare parts from PROXXON!

13.1. Cleaning the housing

For a long service life, the device should be cleaned after
every use with a soft cloth, hand brush or a soft brush. Even
a vacuum cleaner can be recommended.
Cleaning the outside of the houses can be done with a soft,
possibly moist cloth. A soft detergent or other suitable clean-
ing agent may be used. Avoid using solvents or alcohol-
based cleaning agents (e.g. benzine, rubbing alcohol, etc.)
as these will affect the plastic housing shells.
If, despite using the dust suction during operation, it is nec-
essary to clean the inside of the device, please simply swing
up the upper housing part and vacuum the inside of the
device with a vacuum cleaner.

13.2. Cleaning the inside of the device

Never use compressed air for blowing out! The fine wood
dust could become lodged inside the motor or on electrical
components and impair the reliability and the safety of the
machine!
1. Make sure the mains plug is disconnected!
2. Swing open the upper housing part (see also section 6.2
„Unpacking")
3. Vacuum the inside of the device with a vacuum cleaner
4. Push down the upper housing part and lock.

13.3. Replacing the toothed belt

A toothed belt transmits the power from the motor to the saw
blade shaft. The belt has a very long service life, but when
the machine is used extensively, it could be necessary to
replace it after a longer operating period. The procedure is
described here. In case you are unsure, please send the saw
to our Central Service.
1. Make sure the mains plug is disconnected!
2. Set the saw blade to an approx. 40° tilt as explained in
section „Adjusting the saw blade tilt".
3. Swing up the upper housing part as explained in section
6.2
4. Block the shaft with the small Allen key as described in
the Chapter 12.
5. Unscrew the Phillips screw 1 (fig. 17). Remove thrust
washer 2.
