• Advance the counter-pressure roller until just a
short distance from the back of the band saw blade,
once the band saw blade is running, after it has
been tensioned and once its guide has been ad-
justed. This prevents grooves forming in the com-
pression roller, which can lead to damage to the
band saw blade. This action supports the band saw
blade during sawing operations.
• Always use sharpened band saw blades.
• Loosen the sawband when the machine is not in
operation (e.g. after finishing work). Attach a no-
tice 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.
• Use a safe method for cutting pegs, e.g. a depth
limit stop
• For cutting of small wedges, use a guide fixture.
• On curved and irregular cuts, advance the work-
piece using both hands, keeping your fingers
closed. Keep your hands on a safe area of the
workpiece.
• For repeated cutting of curve, irregular cuts, use an
auxiliary template.
• For the cutting of round discs, use a circular cutting
fixture.
• Use a pattern for repeated arced or irregular cuts.
• Insure that the workpiece does not roll when cut-
ting round pieces.
10.1 Rip fence (Fig. 1+11)
The rip fence (5) serves as a guide during longitu-
dinal cuts.
• Clamp the longitudinal fence (5) in the desired po-
sition by pressing the clamping lever (28).
10.2 Transverse cutting gauge (optional) (Fig. 16)
• Slide lateral stop (30) into a groove (a) in the saw
bench.
• Release the grip screw (b). Remove the locking
pin (c) (0°/ 45°).
• Turn the lateral stop (30) until the desired angular
dimension has been set. The arrow (d) on the lat-
eral stop indicates the set angle.
• Retighten the grip screw (b). If necessary, reinstall
the locking pin (c) (0°/ 45°)

• The stop rail (e) can be slid against the lateral stop.
To do so, loosen the knurled screws (f) and slide
the stop rail (e) into the desired position. Tighten
the knurled screws (f) again
• Attention! Do not slide the stop rail (e) too far in the
direction of the saw blade.
10.3 Performing longitudinal cuts (Fig. A)
Here, a workpiece is cut in its longitudinal direction.
• Position the longitudinal fence (5) on the left side
(if possible) of the saw band (Fig. A), in accord-
ance with the desired width.
• Lower the saw band guide (4) onto the workpiece.
• Switch on the saw.
• Press one edge of the workpiece against the lon-
gitudinal fence (5) whilst the flat side lies on the
saw bench (6).
• Slide the workpiece at an even feed rate along the
longitudinal fence (5) into the saw band (Fig. 15).
• Important: Long workpieces must be secured
against tipping at the end of the cutting process
(e.g. with reel-off stand, etc.)
Attention! When processing narrower workpieces it
is essential to use a push stick. The push stick (29)
must always be stored within reach, on the hook pro-
vided for this purpose on the side of the saw (Fig. 2).
10.4 Performing angled cuts (Fig. B+Fig. 6))
• In order to execute angled cuts parallel to the saw
band (Fig. B), it is possible to tilt the saw bench (6)
forwards from 0° - 45°.
• Release the locking handle (20) (Fig. 6).
• Tilt saw bench (6) forwards, until the desired angle
is set on the degree scale. (Fig. 6)
• Retighten the locking handle (20).(Fig. 6)
• Attention: With a tilted saw bench (6), the longitudi-
nal fence (5) must be positioned on the downward
facing side to the right of the saw band in the work-
ing direction (Fig. B) (if the workpiece width allows
this), in order to secure the workpiece against slip-
ping.
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 band guide (4)
must be positioned as close as possible to the
workpiece.
• The workpiece must always be guided with both
hands and kept flat against the band saw bench
(6), in order to prevent a jamming of the saw band.
• Forward feeding should always take place with an
even pressure, which is just sufficient for the saw
band to cut through the material with ease without
becoming blocked.
• Always use the longitudinal fence (5) for all cutting
processes that it can be used for.
• It is better to perform a cut in a single working
step than in multiple steps, which may require that
the workpiece be drawn back. However, if it is not
possible to avoid drawing the workpiece back then
the band saw must be switched off first, and the
workpiece only drawn back once the saw band has
come to a standstill.
• When sawing, the workpiece must always be guid-
ed by its longest side.
• Perform the cut as described under „Performing
longitudinal cuts".
