the bench and guide the saw blade pins into the recess.
Repeat this procedure for the upper blade holder. Push
the upper arm of the saw slightly downwards before
tightening the screws (Fig. 9, 10, 13).
2 Check the positions of the blade pins in both holders
(Fig. 12).
3 Tension the blade using the tensioning tap. Check the
blade tension. Carry on turning clockwise to tension the
blade further (Fig. 11).
Note: It is difficult to open the tensioning tap again if the blade
is too tightly tensioned.
Basic operation
A scroll saw is fundamentally a „curve cutting tool" but
which can also carry out straight and angled edge cuts. Fa-
miliarise yourself with the following important points prior
to commissioning the saw.
• The saw does not automatically cut wood. You must feed
the wood against the saw blade manually.
• The cutting process occurs on I y while the blade is mov-
ing downwards.
• Feed the wood slowly against the saw blade as the saw
blade teeth are small and cut only while moving down-
wards.
• AlI persons carrying out work with the saw require train-
ing. The saw blade may break easily during this train-
ing time Iwhile the operator is sti1l unfamiliar with the
saw.
• The saw is best suited tor sheets of wood less than 2.5
cm thick.
• Feed the wood especially slowly against the blade and
avoid abrupt curves to prevent the saw blade from break-
ing, if you wish to cut wood sheets thickerthan 2.5 cm.
• Saw blade teeth blunten over time, saw blades must be
replaced. The saw blades are sufficient tor 1/2 to 2 op-
erating time depending upon the type of wood.
• Try and make sure that the saw blade follows the grain of
the wood in order to obtain a clean cut.
• deco 402/decotronic: The saw speed must be reduced
to minimum when cutting precious and non-terrous met-
als.
Inside cuts
Warning: Switch off the saw and remove the mains supply plug
before installing saw blades in order to avoid injuries caused
by unintentional activation of the saw.
This saw is suited also to inside cuts cuts not starting at
the edge of the work piece. Proceed as follows:
• Drill a 6 mm hole in the work piece.
• Loosen the blade tension er and release the tension in
the blade.
• Place the bore hole over the saw blade slot in the work
bench.
• Install the saw blade through the hole in the work piece
and through the work blade slot, and fasten the blade to
the holders.
• When you have completed the inside cut, remove the saw
blade and then remove the workpiece from the bench.
m Electrical connection
The installed electric motor is completely wired ready for
operation.
The customer's connection to the power supply system,
and any extension cables that may be used, must conform
with local regulations.

Important remark:
The motor is automatically switched off in the event of an
overload. The motor can be switched on again after a cool-
ing down period that can vary.
Defective electrical connection cables
Electrical connection cables often suffer insulation dam-
age.
Possible causes are:
• Pinch points when connection cables are run through
window or door gaps.
• Kinks resulting from incorrect attachment or laying of
the connection cable.
• Cuts resulting from running over the connecting cable.
• Insulation damage resulting from forcefully pulling out
of the wall socket.
• Cracks through aging of insulation.
Such defective electrical connection cables must not be
used as the insulation damage makes them extremely haz-
ardous.
Check electrical connection cables regularly for damage.
Make sure the cable is disconnected from the mains when
checking.
Electrical connection cables must comply with the regula-
tions applicable in your country.
Single-phase motor
• The mains voltage must coincide with the voltage speci-
fied on the motor's rating plate.
• Extension cables up to a length of 25 m must have a
cross-section of 1.5 mm
2
mm2.
• The connection to the mains must be protected with a
16 A slow-acting fuse.
Only a qualified electrician is permitted to connect the ma-
chine and complete repairs on its electrical equipment.
In the event of enquiries please specify the following da-
ta:
• Motor manufacturer
• Type of current of the motor
• Data recorded on the machine's rating plate
• Data recorded on the switch's rating plate
If a motor has to be returned, it must always be dispatched
with the complete driving unit and switch.
m Maintenance
Warning: In the interests of operational safety, always switch
off the saw and remove the mains plug before carrying out
maintenance work.
General
Re­application of the wax coating on the workbench makes
feeding the workpiece to the blade easier.
Motor
The mains cable should be replaced immediately if pulled
out, cut or damaged in any other way.
Do not lubricate the motor bearings or internal parts!
Saw arm bearings
Lubricate the saw arm bearings every 50 hours. Proceed
as follows (Fig. 14).
