Machine description
Due to its perfected design, the machine offers a versatile
application for processing wood and plastics in the workshop.
The upper and lower bandwheel is protected by a fixed
guard and an articulated cover. Upon opening the cover,
the machine is switched off. Switching on again is only
possible with the cover closed. The non-cutting part of the
sawbelt above the table top is covered by a guard fixed to
the sawbelt guide, the latter being protected against inadvertant opening by the fixed guard of the upper band
wheel. The non-cutting part of the sawbelt under the table
top is protected by a fixed cover.
The swivelling range of the table from -20° to +47° allows
versatile cutting possibilities (e.g.)
• Longitudinal cuts
• Cross cuts
• Diagonal cuts
• Curved and irregular cuts
• Cuts for dovetails and tenons
• On-edge cuts of squared beams

with the machine.
Fig. 8
Release and remove the saw band. Insert a new saw band,
and tension it slightly. Turn the band wheel manually in
the cutting direction, and simultaneously perform the final
tension of the saw band. The tension depends on the
width of the saw band. Wide saw bands must be tensioned
more strongly than narrow ones. An excessive tension results in the premature rupture of the saw band.

of the device. A non-compliance may result in a damage
of the device.
Turn the handwheel clockwise, decrease the cutting
speed. Increase the cutting speed in the opposite direction within the following speed range:
Minimum speed 370 m/min.
For the processing of aluminium, brass, copper, duro-
plastics as well as hard synthetic materials.
Maximum speed 750 m/min.
For the processing of wood.
Saw band guide, Fig. 9
You can adjust the upper saw band guide up to a work
piece height of 160 mm ➂. The smallest possible distance to the work piece ensures the optimum band guide
and a safe working!
Counterpressure bearing, Fig. 10
The counterpressure bearings ➀ absorb the feed pressure
of the work piece.
Adjust the upper and lower counterpressure bearings in
such a manner that they slightly strike against the saw
band back.
Guiding rollers, Fig. 10
Adjust the upper and lower guiding rollers ➁ to the corresponding saw band width. The front edges of the guiding
rollers may at maximum extend until the tooth root surface of the saw band. If the guiding rollers slightly touch
the saw band, fix the position of the rollers with the
knurled screw.
The saw band must not choke up!
Working information:
The following recommendations are examples of the safe use
of band saws. See page K4.
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 working in
closed rooms. A suction device which conforms with
commercial regulations must be used for suction in
commercial areas.
• 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 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.
• For diagonal cuts, place the saw bench in the appropriate position and guide the workpiece on the fence.

GB11
• T o cut dove-tails and dove-tailed tenons or wedges swing
the saw bench to the plus or minus position. Insure safe
workpiece guidance.
• 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.
• Use the traverse cutting gauge special accessory for safety when making traverse cuts.
• To safely cut round plates, use the circular cutting unit
special accessory.
Maintenance
Perform resetting, measuring, and cleaning work
exclusively when the motor is turned off. Disconnect the mains plug, and wait until the rotating
tool stands still.
All protection and safety devices must be immediately rein-
stalled once the repair and maintenance work is completed.
The built-in ball bearings are maintenance-free.
Recommendations:
1. Slightly re-lubricate the slewing segments of the table
and the bend tensioning device.
2. Regularly clean the saw band. Wood leaves resin sediments. We recommend the deresinifying concentrate
Pharmol HEK, item no. 61009700 for the cleaning.
3. Regularly check the guiding rollers and the counterpressure bearings. If required, readjust or disassemble them, and grease or exchange the parts.
4. Exchange worn-out table inserts (item no.
73240034).
5. Ensure that the tabletop is always free of resin.
6. Regularly lubricate the bearings of the speed handwheel.
Electrical Connection
The installed electric motor
is connected and is ready to work.
The connection complies with the relevant VDE and DIN
regulations.
The customer-side mains supply and the used extension line
must meet these regulations.
Installations, repair, and maintenance work relating to the
electric installation may only be performed by specialists.
