9.4. Tensioning the saw band (Fig. 1a)
ATTENTION! If the saw is at a standstill for an extend-
ed 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 (22). The correct tension of the
saw band can be determined by pressing the finger
laterally against the saw band, roughly centrally be-
tween the two saw band rollers (2+8). The Bandsaw
blade (22) 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.
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.
9.5 Adjusting the saw band (Fig. 1a+1b)
ATTENTION! Before it is possible to implement the
saw band setting, the saw band must be tensioned
correctly.
• Open the side covers (11) by undoing the top (13)
and bottom (10) cover locks. First unlock the top
cover lock (13) with the help of the 6 mm Allen key
(28) by turning this counter-clockwise. Then unlock
the bottom cover lock (10) by unscrewing it coun-
ter-clockwise.
• Slowly turn the saw band roller (2) clockwise. The
Bandsaw blade (22) 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 (22) runs more towards the
rear edge of the saw band roller (2) then the set
screw (15) must be rotated anticlockwise.
• Open the locking screw for the top saw band roll-
er (14).
• Turn the bottom saw band roller (8) slowly by hand,
to check the position of the Bandsaw blade (22).
• If the Bandsaw blade (22) runs more towards the
front edge of the saw band roller (2) then the set
screw (15) must be rotated clockwise.
• After setting the top saw band roller (2), check the
position of the Bandsaw blade (22) on the bottom
saw band roller (8). The Bandsaw blade (22) should
also lie centrally on the saw band roller (8) 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 (8).
• Tighten the locking screw for the top saw band roll-
er (14).
• Once adjustment is complete, close the side cover
(11) again with the bottom (10) and top (13) cover
locks in reverse order.
9.6. Adjusting the saw band guide (Fig. 6-9)
Both the support bearing (36 + 42) and the guide pins
(37 + 46) must be readjusted after every saw band
change.
• Open the side covers (11) by undoing the top (13)
and bottom (10) cover locks. First unlock the top
cover lock (13) with the help of the 6 mm Allen key
(29) by turning this counterclockwise. Then unlock
the bottom cover lock (10) by unscrewing it coun-
terclockwise.
• Once adjustment is complete, close the side cover
(11) again with the bottom (10) and top (13) cover
locks in reverse order.
9.6.1. Top support bearing (36) ( Fig. 6)
• Undo Allen screw for top support bearing (35).
• Move support bearing (36) sufficiently far that it just
no longer touches the Bandsaw blade (22) (distance
max. 0.5 mm).
• Retighten the Allen screw for the top support bear-
ing (35).
9.6.2. Adjusting the bottom support bearing (42)
(Fig. 8)
• Disassemble the saw table as per 9.1 in the oppo-
site direction.
• Undo Allen screw for bottom support bearing (41).
• Move bottom support bearing (42) sufficiently far
that it just no longer touches the Bandsaw blade
(22) (distance max. 0.5 mm).
• Retighten Allen screw for bottom support bearing
(41).
9.6.3. Adjusting the top guide rollers (37)
(Fig. 6+7)
• Undo Allen screws for top retainer (40)
• Move top retainer (39), top guide rollers (37), until
the front edge of the guide rollers (37) is approx. 1
mm behind the tooth base of the saw band.
• Retighten Allen screws for top retainer (40).
