If the saw band is tensioned in position B of the
quick-release lever (61) (release) with the tensioning
screw (1) and then with the quick-release lever (61),
the saw band may break.
• Turn the clamping screw (1) clockwise to tension the
Bandsaw blade (26). The correct tension of the saw
band can be determined by pressing the finger laterally
against the saw band, roughly centrally between the
two saw band rollers (2+9). The Bandsaw blade (26)
should only depress slightly (approx. 1 - 2 mm) here.
• The sufficiently tensioned saw band makes a metal-
lic sound when tapped.
• Relieve the saw band tension if it is not in use for
an extended time, so that it does not become over-
stretched. To do this, move the quick-release lever
(61) to position B (release).
m ATTENTION! With high tension, the saw band may
break. RISK OF INJURY! If the tension is too low, the
driven saw band roller (8) may spin, resulting in the saw
band coming to a standstill.
8.7 Adjusting the saw band (Fig. 1 + 1a)
m ATTENTION! Before it is possible to implement the
saw band setting, the saw band must be tensioned cor-
rectly.
• Open the side covers (13) by undoing the cover locking
mechanisms (12) with the help of the screwdriver (33).
• Slowly turn the saw band roller (2) clockwise. The
Bandsaw blade (26) should run centrally on the saw
band roller (2). If this is not the case, the angle of the
top saw band roller (2) must be corrected.
• If the Bandsaw blade (26) runs more towards the
rear edge of the saw band roller (2) then the set
screw (17) must be rotated anticlockwise.
• Open the locking screw for the top saw band roller
(16).
• Turn the bottom saw band roller (9) slowly by hand,
to check the position of the Bandsaw blade (26).
• If the Bandsaw blade (26) runs more towards the
front edge of the saw band roller (2) then the set
screw (17) must be rotated clockwise.
• After setting the top saw band roller (2), check the
position of the Bandsaw blade (26) on the bottom
saw band roller (8). The Bandsaw blade (26) should
also lie centrally on the saw band roller (9) here. If
this is not the case, the angle of the top saw band
roller (2) must be adjusted again.
• Turn the saw band roller a few times, until the ad-
justment of the top saw band roller (2) acts on the
saw band position on the bottom saw band roller (9).
• Tighten the locking screw for the top saw band roller
(16).
• Once adjustment is complete, close the side covers
(13) again and secure with the cover locking mecha-
nisms (12) with the help of the screwdriver (33).
8.8 Adjusting the saw band guide (Fig. 7 - 10)
Both the support bearing (46 + 52) and the guide pins (47
+ 56) must be readjusted after every saw band change.
• Open the side covers (13) by undoing the cover locking
mechanisms (12) with the help of the screwdriver (33).
8.8.1 Top support bearing (46) ( Fig. 7)
• Undo Allen screw for top support bearing (45).
• Move support bearing (46) sufficiently far that it just
no longer touches the Bandsaw blade (26) (distance
max. 0.5 mm).
• Retighten the Allen screw for the top support bear-
ing (45).
8.8.2 Adjusting the bottom support bearing (52)
(Fig. 9)
• Disassemble the saw table as per 8.1 in the opposite
direction.
• Undo Allen screw for bottom support bearing (51).
• Move bottom support bearing (52) sufficiently far
that it just no longer touches the Bandsaw blade (26)
(distance max. 0.5 mm).
• Retighten Allen screw for bottom support bearing (51).
8.8.3 Adjusting the top guide pins (47) (Fig. 7 + 8)
• Undo Allen screws for top retainer (50)
• Move top retainer (49), top guide pins (47), until the
front edge of the guide pins (47) is approx. 1 mm
behind the tooth base of the saw band.
• Retighten Allen screws for top retainer (50).
m ATTENTION! The saw band will be unusable if the
teeth touch the guide pins with the saw band running.
• Undo Allen screws for top guide pins (48).
• Slide the guide pins (47) in the direction of the saw
band!
m ATTENTION! The distance between the guide pins
(47) and Bandsaw blade (26) must not exceed 0.5 mm.
(Saw band must not jam)
• Retighten Allen screws (48).
• Turn the top saw band roller (2) a few times in a
clockwise direction.
• Check the setting of the top guide pins (47) again
and adjust if necessary.
• If necessary, adjust the top support bearing (46)
(8.8.1).
