8.6 Tensioning the saw band (Fig. 1)
m ATTENTION! If the saw is at a standstill for an ex-
tended period the saw band tension must be relieved,
i.e. before switching the saw on it is necessary to
check the saw blade tension.
• 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 fin-
ger laterally against the saw band, roughly centrally
between the two saw band rollers (2+9). The Band-
saw blade (26) should only depress slightly (approx.
1-2 mm) here.
• The sufficiently tensioned saw band makes a me-
tallic 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.
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 ten-
sioned correctly.
• Open the side covers (13) by undoing the cover
locking mechanisms (12) with the help of the screw-
driver (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 mech-
anisms (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 screw-
driver (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) (dis-
tance 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 op-
posite 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).
8.8.4 Adjusting the bottom guide pins (56) (Fig. 9+10)
• Disassemble saw table (7)
• Undo screw for bottom retainer (53) (Allen key, size
5)
• Move bottom retainer (57), bottom guide pins (56),
until the front edge of the bottom guide pins (56) is
approx. 1 mm behind the tooth base of the saw band.
• Retighten screw for bottom retainer (53).
m ATTENTION! The saw band will be unusable if the
teeth touch the guide pins with the saw band running.
• Undo Allen screws for bottom guide pins (55).
• Slide the two bottom guide pins (56) sufficiently far
in the direction of the saw band that the distance
between the guide pins (56) and Bandsaw blade
(26) is max. 0.5 mm. (Saw band must not jam)
• Retighten Allen screws for bottom guide pins (55).
• Turn the bottom saw band roller (9) a few times in a
clockwise direction.
