Sawing; General Tips On Sawing; Changing The Saw Blade - Proxxon FET Manual De Instrucciones

1. To adjust the angle, release knurled screw 4 and set the
desired value at the scale 5. Retighten knurled screw 4.
Adjust position of limit stop strip 1 and clamp firmly by
tightening the knurled screw 3.
2. Caution! Make sure at all costs that the limit stop strip 1 is
correctly seated in the receiver of the angle stop 2 and
that there is sufficient distance from the end of the limit
stop strip to saw blade 7! In all cases: Switch off the saw
and disconnect the mains plug and test to see that the
limit stop strip does by no means touch the saw blade or
the saw blade guard, see fig. 13c!
3. Insert clamping piece 8 in the guide of the limit stop strip
(fig. 13d) and determine the position in dependence on
the desired work piece length. Please note: The hexagon
nut travels in the guide of the limit stop! Fix the clamping
piece with the knurled screw 9.
While sawing, the piece to be sawn is pushed up to the limit
stop and can be crosscut as shown in fig. 12.

11. Sawing

Your FET may not be used for slitting (notch completed in the
work piece)! To groove or notch, please by all means use the
Proxxon groove-milling device (article number 28736).
Hold the work piece on the saw table as shown in fig. 14.
Adapt the feed according to the material, the saw blade and
the work piece thickness! Hard materials, fine saw blades
and thick work pieces do not "tolerate" as much feed as soft
materials, rough saw blades and thin materials.
Always operate the saw from the position as shown in Fig.
14a so that you are always in optimal control of the work
piece. Stand in front of the saw while sawing! Never saw with
your FET from the side or even from the back. Ensure
sufficient stability while you work!
If you process correspondingly small work pieces then use
the included push-rod, as shown in fig. 15. This prevents
your hands from coming to close to the revolving saw blade
and thus reduces the risk of injury:
Always keep the push-rod close to hand while working!
If the device is not in use, please use the supplied push-rod
in the designated housing fixture (fig. 14b)!
Please note:
• Only use perfect saw blades.
• Always remove the mains plug for maintenance and
upkeep work.
• Do not let the device operate unsupervised.
When sawing, press the work piece onto the work plate,
guide with sensitivity and with little force, more pressure on
the work plate, less pressure against the saw blade. Guide
the work piece slowly into the saw blade, particularly if the
blade is very thin and the teeth very fine or if the work piece
is very thick.

Caution!

11.1. General tips on sawing

For good results, please note the following points:
• When sawing, press the work piece onto the work plate,
guide with sensitivity and with little force; more pressure on
the work plate, less pressure against the saw blade.
• Make sure that the work piece is lying properly on the saw
table (no burrs or sawdust)
• Adapt the feed to the requirements by saw blade, speed
and work piece material.
• Guide the work piece slowly into the saw blade, particularly
if the blade is very thin and the teeth very fine or if the work
piece is very thick.
• Only use perfect saw blades. Make sure that the saw
blades are suitable for use with the FET. You must comply
with the dimensions specified in the technical data.
• Do not let the device operate unsupervised.
• Carefully mark out the check line.
• Make sure there is good lighting.
• Always work with connected dust suction!
• If necessary, use the included push-rod to feed the work
piece.
• Always work with the saw blade guard and splitting wedge.
Make sure that the protective devices are in a perfect
condition.
• Prevent the saw blade from blocking! Always work with
adjusted feed and avoid jamming the work piece. If the saw
blade blocks all the same, please carefully pull out the work
piece against the feed direction so that the saw blade can
rotate freely again.

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.
