• Relieve the bandsaw blade (21) tension by turning
the clamping screw (1) anti-clockwise.
• Remove the bandsaw blade (21) from the saw band
rollers (2+8) and through the slot in the saw table
(7).
• Place the new bandsaw blade (21) centrally on both
saw band rollers (2+8). The teeth of the bandsaw
blade (21) must point downwards in the direction of
the saw table (Fig. 6).
• Tension the bandsaw blade (21) (see 8.2)
• Close the side cover (11) again.
• Re-install the U-reinforcement (34).
8.9 Replacing the table insert (Fig. 13)
• In case of wear or damage, the table insert (6) must
be replaced; otherwise there is an increased risk
of injury.
• Remove the worn table insert (6) by lifting it up and
out.
• Installation of the new table insert takes place in
reverse order.
8.10 Extraction nozzle (Fig. 1b)
• The band saw is equipped with an extraction noz-
zle (19) Ø 40 mm for chips.
• Only operate the device with a suitable extraction
system. Check and clean the suction channels at
regular intervals.
8.11 Push Stick retainer (Fig. 12)
• The Push Stick retainer (48) is pre-mounted on the
machine frame. If unused, the Push stick (26) must
always be stowed in the Push Stick retainer.
9. Operation
9.1 On/Off switch (12) (Fig. 15)
• To turn the machine on, press the green button „I".
• To turn the machine off again, press the red button
„0".
• The band saw is equipped with an undervoltage
switch. With a power failure, the band saw must be
switched back on again.
9.2 Parallel stop (Fig. 16)
• Press the clamping bar (25) of the parallel stop (24)
upwards
• Slide the parallel stop (24) left or right of the Band-
saw blade (21) on the saw table (7) and set to the
desired measurement.
• Press the clamping bar (25) down to fix the parallel
stop (24) in place. In order to increase the clamping
force of the clamping bar (25), rotate it clockwise
until the parallel stop is sufficiently fixed in place.
• Make sure that the parallel stop (24) always runs
parallel to the bandsaw blade (21).
9.3 Angled cuts (Fig. 17)
In order to execute angled cuts parallel to the band-
saw blade (21), it is possible to tilt the saw bench (7)
forwards from 0° - 45°.
• Undo locking handle (20) and wing nut (31).

• Tilt saw bench (7) forwards, until the desired angle
is set on the degree scale (17).
• Retighten the locking handle (20) and wing nut (31).
• Attention: With a tilted saw table (7), the parallel
stop (24) must always be fitted to the right of the
bandsaw blade (21) in the working direction. This
prevents the workpiece from slipping.
10. Working instructions
The following recommendations are examples of the
safe use of band saws.
The following safe working methods should be seen
as an aid to safety. They cannot be applied suitably
completely or comprehensively to every use. They
cannot treat every possible dangerous condition and
must be interpreted carefully.
• Connect the machine to a suction unit when work-
ing in closed rooms.
• Loosen the sawband when the machine is not in
operation (e.g. after finishing work). Attach a notice
on the tension of the saw band to the machine for
the next user.
• Collect unused sawbands and store them safely in
a dry place. Check for faults (teeth, cracks) before
use. Do not use faulty sawbands!
• Wear suitable gloves when handling sawbands.
• All protective and safety devices must be securely
mounted on the machine before beginning work.
• Never clean the sawband or the sawband guide
with a hand-held brush or scraper while the saw-
band is running. Resin-covered sawbands impair
working safety and must be cleaned regularly.
• For your own protection, wear protective glasses
and hearing protection. Wear a hairnet if you have
long hair. Roll up loose sleeves over the elbows.
• Always position the sawband guide as near the
workpiece as possible when working.
• Insure sufficient lighting in the work area and
around the machine.
• Always use the fence for straight cuts to keep the
workpiece from tipping or slipping away.
• When working on narrow workpieces with manual
feed, use the push stick.
• For diagonal cuts, place the saw bench in the ap-
propriate position and guide the workpiece on the
fence.
• In order to cut dovetail tenons and teeth or wedges,
bring the saw table into the corresponding position
on the angle scale.
• For arced and irregular cuts, push the workpiece
evenly using both hands with the fingers together.
Hold the workpiece with your hands on a safe area.
• Use a pattern for repeated arced or irregular cuts.
• Insure that the workpiece does not roll when cutting
round pieces.
• Attention! After every new setting, we recommend
performing a test cut, in order to check the dimen-
sional settings.
• With all cutting processes, the top saw band guide
(5) must be positioned as close as possible to the
workpiece (see 8.5).
