A
Danger!
If the table insert is damaged, small
objects may get caught between the
table insert and the kerf plate and
block the saw blade. Replace dam
-
aged table inserts immediately!
Speed adjustment
By shifting the drive belt the band saw
can be operated at two speeds (see
“Technical specifications”):
− 408 m/min for hard wood, plastics
and non-ferrous metals (with special
band saw blade);
− 965 m/min for all kinds of wood.
A
Caution!
The drive belt must not run in a diago-
nal position; this will damage the belt
8.1 Band saw blade align-
ment
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 (68).
2. Setting knob (67):
− Turn setting knob (67) clockwise
if the band saw blade runs
towards the front of the saw.
− Turn setting knob (67) counter-
clockwise if the band saw blade
runs towards the rear of the saw.
3. Tighten locking nut (68).
8.2 Upper blade guide align-
ment
The upper blade guide consists of:
− a thrust bearing (supports 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 or tracking.

Note:
Periodically check all bearings for
wear, if necessary 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 (69) lock
screw (70).
3. Adjust thrust bearing position (dis-
tance 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 knurled nut (72).
2. Set guide bearings (73) with the
knurled thumb screws (71) against
the band saw blade.
3. Turn band saw wheel by hand in a
clockwise direction several times to
bring the guide bearings in correct
position – both guide bearings
should just touch the band saw
blade.
4. Retighten knurled nut (72) to lock
the knurled thumb screw (71).
8.3 Aligning the Lower Blade
Guide
The lower blade guide consists of:
− a thrust bearing (supports 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 track-
ing adjustment:

Note:
Periodically check thrust bearings
and guide bearings for wear, if neces
-
sary replace both guide bearings at the
same time.
Basic alignment
1. Open the lower housing door.
2. Slide hand guard into lower position
and open lower blade guard
(74).
3. Loosen the screw (75) for the lower
blade guide.
4. Adjust position of lower blade guide
until band saw blade is centred
between the guide bearings (76).
5. Tighten screw (75).
Adjusting the thrust bearing
1. Loosen the thrust bearing's lock
screw
(80).
2. Adjust thrust bearing position (81)
(distance thrust bearing - band saw
blade = 0.5 mm – if the band saw
blade is turned by hand, it shall not
touch the thrust bearing).
3. Tighten the thrust bearing lock
screw
(80).
Adjusting the guide bearings
1. Loosen the knurled nut (78).
