Note:
Always make a trial cut in a piece of scrap to verify
settings; correct if necessary before cutting the
work piece.
5. Place work piece on the saw table.
6. Start saw.
7. Cut work piece in a single pass.
8. Switch off if no further cutting is to be done
immediately afterwards.
9. If work should not be continued immediately:
reduce saw blade tension and attach a note at
the device that the saw blade needs to be set
again prior to the next sawing process (see
chapter "Tensioning the Band Saw Blade")
9. Care and Maintenance
Danger!
Prior to all servicing:
1. switch machine OFF;
2. Wait until the saw has come to a complete
stop.
3. Unplug power cable;
Check to see that all safety devices are
operational again after each service.
Replace defective parts, especially of safety
devices, only with genuine replacement parts.
Parts not tested and approved by the
manufacturer can cause unforeseen damage.
Repair and maintenance work other than
described in this section should only be carried
out by qualified specialists.
Danger!
With a damaged table insert there is a risk of
small parts getting stuck between table insert
and saw band, blocking the saw band.
Replace damaged table inserts immediately!
Speed adjustment
By turning over the drive belt, the band saw blade
can be operated with two speed levels (see
"technical specifications"):
430 m/min for wood and plastics
1020 m/min for all kinds of wood.
430 m/min
1020 m/min
Caution!
The drive belt must not run in a diagonal
position; this will damage the belt
9.1 Aligning the Band Saw Blade
If the band saw blade does not run in the centre of
the rubber tyres, the tracking needs to be
corrected by adjusting the tilt of the upper band
saw wheel:
1. Loosen lock nut (42).
2. Turn setting knob (20):
Turn setting knob (20) clockwise if the band
saw blade runs towards the front of the saw.
Turn setting knob (20) counter-clockwise if
the band saw blade runs towards the rear of
the saw.

3. Tighten lock nut (42) again.
9.2 Aligning the Upper Blade Guide
The upper blade guide consists of:
a thrust bearing (supporting the band saw blade
from the rear),
two guide bearings (providing lateral support).
All bearings need to be readjusted after every
band saw blade change and/or tracking
adjustment.
Note:
Periodically check all bearings for wear, if neces-
sary replace both guide bearings at the same
time.
Adjusting the thrust bearing
1. If necessary, align and tighten the band saw
blade.
2. Loosen the thrust bearing`s (43) lock screw
(44) .
44
3. Adjust thrust bearing position (distance thrust
bearing - band saw blade = 0.5 mm – if the
band saw blade is turned by hand, it must not
touch the thrust bearing).
4. Tighten the thrust bearing lock screw.
Adjusting the guide bearings
1. Loosen the knurled nut (46) .
2. Set guide bearings (47) with the knurled
thumb screws (45) against the saw blade.
3. Turn band saw wheel by hand in a clockwise
direction several times to bring the guide bear-
ings in correct position – both guide bearings
should just touch the band saw blade.
4. Retighten knurled nut (46) to lock the knurled
thumb screw (45) .
9.3 Aligning the Lower Blade Guide
The lower blade guide consists of:
a thrust bearing (supporting the band saw blade
from the rear),
two guide bearings (providing lateral support).
These parts need to be readjusted after every
band saw blade change or tracking adjustment:
Note:
Periodically check thrust bearings and guide bear-
ings for wear, if necessary replace both guide
bearings at the same time.
Basic alignment
1. Open the lower housing door.
2. Push the contact protection into the lower
position and open the saw belt cover (48).
3. Loosen the screw (49) for lower blade guide.
4. Adjust the position of lower blade guide until
band saw blade is centred between the guide
bearings (50) .
5. Tighten screw (49) .
48
Adjusting the thrust bearing
1. Loosen the screw (53) for thrust bearing.
2. Align thrust bearing (54)(distance from thrust
bearing belt = 0.5 mm – when the saw belt is
moved by hand it must not touch the thrust
bearing).
3. Retighten the screw (53) for thrust bearing.
43
Adjusting the guide bearings
1. Loosen the knurled nut (51) .
2. Set guide bearings (50) with the knurled
thumb screws (52) against the band saw
45
blade.
3. Turn band saw wheel by hand in a clockwise
direction several times to bring the guide bear-
ings in correct position – both guide bearings
should just touch the band saw blade.
46
4. Retighten knurled nut (51) to lock the knurled
thumb screw .
5. Close the lower saw blade guard (48) .
6. Close the lower housing door.
9.4 Replacing the Band Saw Tyre
Periodically check band saw tyres for wear.
Replace only in pairs:
47
1. Remove band saw blade (see "Care and
Maintenance");
2. Lift band saw tyre with a small screwdriver,
then pull off the band saw wheel.
