Round sawing blades (with flat ends) can ideally be used for
plastic, hard and soft wood. They cut on all sides, so it is not
necessary to turn the work piece when sawing.
10 Selecting the speed:
This representation can, of course, only give instructions on
the general direction to take. As in the previous section, you
have to "experiment" a little to find the optimal result. The
appropriate speed also, of course, depends on the blade
used, the material of the work piece, the feed etc.
Level
400 strokes
1600 strokes
10.1.1 Possible causes of faults:
The following causes may break the saw blade:
– If blade is tensioned too tightly or not tightly enough
– Mechanical overloading of the blade by feeding too quickly.
– Bending or twisting of the blade when turning the work
piece too quickly when cutting curves.
– When the wear limit of the saw blade has been reached.
– If the screws are tightened on saw blades with cross pin.
10.2 Sawing (fig. 7)
Hold the work piece on the saw table as shown in fig. 7.
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.
You can also experiment with various speeds.
Safe and precise work is only possible with careful fixing!
The mechanical scroll saw is predominantly a machine for
sawing curves. For good results, please note the following
points:
Please note:
– Only use perfect saw blades.
– Always remove the mains plug for maintenance and upkeep
work.
– Do not let the device operate unsupervised.

NOTE:
1. When sawing, press the work piece onto the work plate,
guide by feeling and with little power, more pressure on the
work plate, less pressure against the saw blade. Caution!
The saw does not cut the work piece itself. You must guide
the work piece into the saw blade.
2. 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. You will achieve the best results if the
wood thickness is less than 25 mm.
3. Please observe the instructions under 8.1.
10.2.1 Inside cuts (fig. 8)
CAUTION!
Always remove the mains plug before releasing the saw
blade.
If you must also make inside cuts when working with your
mechanical scroll saw, proceed as follows:
1. Drill a hole in the inside part 1 to be cut out of your work
piece.
2. Take the saw blade from the top saw blade guide 2.
Proceed as shown in 8.7.5.1 and in 8.7.5.2, depending on
the type of saw blade used.
3. Push the saw blade through the drill hole. Reattach saw
blade at the top. Tension the saw blade properly again.
4. Cut out the opening and remove the work piece once the
saw blade has been removed again.
Tip: If you drill the hole in such a way that it does not touch
the later inside contour, you can allow the saw line to run
tangentially into the contour. This produces a nice even
sawing edge.
10.2.2 Grain cuts:
For grain cuts, the table is simply tilted by the required
amount. This works as follows:
1. Slightly loosen toggle screw 1 (fig. 2) and align saw table 2
to the required value, using scale 9 on indicator 8.
2. Tighten toggle screw 1.
3. Press the work piece particularly firmly against the table for
a grain cut.
