ATTENTION!
Before all maintenance, set-up and assembly work
on the band saw, unplug the mains plug.
Assembly tools
1 Open-ended spanner, size 10/13
1 Allen key, size 3
1 Allen key, size 4
1 Screwdriver
The saw table is not assembled for packaging rea-
sons.
9.1. Assembling the saw table (Fig. 2-4)
• Remove the wing nut (31), the locking handle (20),
the two washers and the clamping plate (32). (Fig.
2)
• Remove the two knurled nuts (33), the U-reinforce-
ment (34) and the two countersunk screws M6x16
from the saw table. (Fig. 3)
• Guide the saw table (7) over the Bandsaw blade
(21). Fasten it to the two screws on the machine
frame with the plate (32), the two washers, the
wing nut (31) and the locking handle (20). (Fig. 4)
• Fasten the U-reinforcement (34) to the front side
of the saw table with 2 countersunk screws M6x16
and 2 knurled nuts (33). (Fig.3)
9.2. Tensioning the saw band (Fig. 1a)
• ATTENTION! If the saw is at a standstill for an
extended period the saw band tension must be
relieved, i.e. before switching the saw on it is nec-
essary to check the saw blade tension.
• Turn the clamping screw (1) clockwise to tension
the Bandsaw blade (21). The correct tension of
the saw band can be determined by pressing the
finger laterally against the saw band, roughly cen-
trally between the two saw band rollers (2+8). The
Bandsaw blade (21) 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
overstretched.
• 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.
9.3 Adjusting the saw band (Fig. 1a+1b)
• ATTENTION! Before it is possible to implement
the saw band setting, the saw band must be ten-
sioned correctly.
• Open the side covers (11) by undoing the cov-
er locking mechanisms (10) with the help of the
screwdriver (29).
• Slowly turn the saw band roller (2) clockwise. The
Bandsaw blade (21) 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 (21) runs more towards the
rear edge of the saw band roller (2) then the set
screw (14) must be rotated anticlockwise.
• Open the locking screw for the top saw band roller
(13).
26 GB
• Turn the bottom saw band roller (8) slowly by hand,
to check the position of the Bandsaw blade (21).
• If the Bandsaw blade (21) runs more towards the
front edge of the saw band roller (2) then the set
screw (14) must be rotated clockwise.
• After setting the top saw band roller (2), check
the position of the Bandsaw blade (21) on the bot-
tom saw band roller (8). The Bandsaw blade (21)
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
roller (13).
• Once adjustment is complete, close the side cov-
ers (11) again and secure with the cover locking
mechanisms (10) with the help of the screwdriver
(29).
9.4. Adjusting the saw band guide (Fig. 5 - 8)
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 cov-
er locking mechanisms (10) with the help of the
screwdriver (29).
9.4.1. Top support bearing (36) ( Fig. 5)
• Undo Allen screw for top support bearing (35).
• Move support bearing (36) sufficiently far that it
just no longer touches the Bandsaw blade (21) (dis-
tance max. 0.5 mm).
• Retighten the Allen screw for the top support bear-
ing (35).
9.4.2. Adjusting the bottom support bearing (42)
(Fig. 7)
• Disassemble the saw table as per 9.1 in the op-
posite 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
(21) (distance max. 0.5 mm).
• Retighten Allen screw for bottom support bearing
(41).
9.4.3. Adjusting the top guide pins (37)
• Undo Allen screws for top retainer (40)
• Move top retainer (39), top guide pins (37), until the
front edge of the guide pins (37) is approx. 1 mm
behind the tooth base of the saw band.
• Retighten Allen screws for top retainer (40).
• ATTENTION! The saw band will be unusable if the
teeth touch the guide pins with the saw band run-
ning.
• Undo Allen screws for top guide pins (38).
• Slide the guide pins (37) in the direction of the
saw band!
Attention! The distance between the guide pins
(37) and Bandsaw blade (21) must not exceed 0.5
mm. (Saw band must not jam)
• Retighten Allen screws (38).
• Turn the top saw band roller (2) a few times in a
clockwise direction.
