- Negative pressure at recommended air speed:
1500 PA
- Recommended air speed: 20 ms
• 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 ten-
sioned and once its guide has been adjusted. This
prevents grooves forming in the compression 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 sawband 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 cutting
round pieces.

10.1 Rip fence, Fig. 1+11
The rip fence (5) serves as a guide during longitudi-
nal cuts.
-1
• Clamp the longitudinal fence (5) in the desired posi-
tion by pressing the clamping lever (28).
10.2 Transverse cutting gauge, Fig. 20
• 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 lateral
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 accordance
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 (24) pro-
vided for this purpose on the side of the saw (Fig. 2).
10.4 Performing angled cuts, Fig. B+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)
