to be cut.
• Retighten locking handle (28).
• Check the setting before every cutting process and
adjust if necessary.
8.10 Adjusting the saw table (7) to 90°
(Fig. 2+12+13)
• Set the top saw blade guide (5) fully upwards. (8.9)
• Undo locking handle (22) and wing nut (21) (Fig. 2).
• Place the angle bracket between the Bandsaw blade
(26) and saw table (7). Angle bracket not included in
the scope of supply.
• Tilt the saw table (7) by turning, until the angle to the
Bandsaw blade (26) is precisely 90°. If the saw table
is already on the screw (58) and a 90° angle cannot
be set, undo the nut (59) and shorten the screw (58)
by turning in a clockwise direction.
• Retighten the locking handle (22) and wing nut (21).
• Also undo the nut (59).
• Adjust the screw (58) sufficiently that the saw table
touches the underside.
• Retighten the nut (58) to fix the screw (59) in posi-
tion.
8.11 Which saw band to use
The saw band supplied in the band saw is intended for
universal use. The following criteria should be consid-
ered when selecting the saw band:
• It is possible to cut tighter radii with a narrow saw
band than with a wide saw band.
• A wide saw band is used if a straight cut is required.
This is important in particular when cutting wood.
The saw band has a tendency to follow the wood
grain and therefore deviates easily from the desired
cutting line.
• Fine-toothed saw bands cut more smoothly, but also
more slowly than coarse saw bands.
m ATTENTION! Never use bent or torn saw bands!
8.12 Push Stick retainer (Fig. 14)
The Push Stick retainer (60) is pre-mounted on the ma-
chine frame. If unused, the Push stick (29) must always
be stowed in the Push Stick retainer.
8.13 Replacing the table insert (Fig. 15)
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 re-
verse order.
8.14 Replacing the saw band (Fig. 1a+1b+14)
• Set the saw band guide (5) at approx. half height
between the saw table (7) and machine frame (18).
• Undo the cover locking mechanisms (12) and open
the side covers (13).
• Remove the screw M6x35 (36) with two washers
(37) and the nut (38) of the table. (Fig. 3)
• Relieve the Bandsaw blade (26) tension by turning
the clamping screw (1) anti-clockwise.
• Remove the Bandsaw blade (26) from the saw band
rollers (2+9) and through the slot in the saw table (7).
• Place the new Bandsaw blade (26) centrally on both
saw band rollers (2+9). The teeth of the Bandsaw
blade (26) must point downwards in the direction of
the saw table (Fig. 6).
• Tension the Bandsaw blade (26) (see 8.6)
• Close the side cover (13) again.
• Mount the M6x35 bolt (36) to the table with two
washers (37) and the nut (38). (Fig. 3)
8.15 Extraction nozzle (Fig. 1b)
The band saw is equipped with an extraction nozzle
(24) Ø 40 mm for chips.
Only operate the device with a suitable extraction sys-
tem. Check and clean the suction channels at regular
intervals.

8.16 Mitre gauge (optional) (25) (Fig. 23)
• Slide lateral stop (25) into a groove (A) in the saw
bench.
• Release the grip screw (E).
• Turn the lateral stop (C) until the desired angular di-
mension has been set. The arrow (F) on the lateral
stop indicates the set angle.
• Retighten the grip screw (E).
• The stop rail (B) can be slid against the lateral stop
(C). To do so, loosen the knurled screws (D) and
slide the stop rail (B) into the desired position. Tight-
en the knurled screws (D) again
m ATTENTION! Do not slide the stop rail (B) too far
in the direction of the saw blade.
m ATTENTION! When working with the machine, all
protective devices and guards must be fitted.
The upper and lower bandwheel is protected by a fixed
guard and an articulated cover. When opening the cov-
er, the machine is switched off. Starting is possible
only with closed cover.
9. Operation
9.1 On/Off switch (15) (Fig. 17)
• 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 under voltage
switch. With a power failure, the band saw must be
switched back on again.
9.2 Fitting the parallel stop (Fig. 5+18)
• Place the parallel stop (14) on the guide rail (43) to
the left or right of the sawing blade.
• Press the clamping bar (42) down to fix the parallel
stop (14) in place. The clamping force of the parallel
stop can be adjusted at the rear knurled nut (41).
• Make sure that the parallel stop (14) always runs par-
allel to the band saw blade (26).
9.3 Angled cuts (Fig. 20)
In order to execute angled cuts parallel to the band saw
blade (26), it is possible to tilt the saw bench (7) for-
wards from 0° - 45°.
• Undo locking handle (22) and wing nut (21).
• Tilt saw bench (7) forwards, until the desired angle is
set on the degree scale (35).
• Retighten the locking handle (22) and wing nut (21).
