• Remove the parallel stop and the table width en-
largement in reverse order (Fig. 7-8).
• Open the saw band guard, top and bottom.
• Relieve the saw band tension with the clamping
screw (11), remove the band. Fig. 11
• Insert a new saw band.
Side correction (Fig. 11)
• The sawblade should run in the centre of the band
wheels.
• Turn the upper band wheel by hand in the cutting
direction, and make the side correction by means
of the handle (J).
• Attention! The saw band should run over the cen-
tre of the band wheel after multiple turns. Visual
inspection!
• Turn the band wheel by hand in the cutting direc-
tion while determining the final tension with the ten-
sion screw (11). The degree of tensioning depends
on the sawblade width. Wide sawblades must be
tensioned more than narrow ones.
• After successful setting firmly tighten the locknut
(N). Close the guard.
Attention: Too strong a tensioning will cause prema-
ture breaking.
• Fit the table width enlargement in reverse order.
(Fig. 7-7.4)
• After termination of the work, always relieve the
tension by releasing tension bolt (11).
8.8 Setting the number
(Fig.12+13+13.1)
Pull the mains plug!
• Open lower guard. The table top has to be tilted slightly.
• Release the belt with the tension handle (12).
• Put the belt into the desired position. (S1 or S2).
• Retension the belt with the tension handle (12).
• Close the lower guard.
Rpm range:
Rpm stage 1 360 m/min.
For processing hardwood, materials similar to hard-
wood and for fine cuts.
Rpm stage 2 720 m/min.
For processing softwoods and for less fine cuts.
8.9 Sawblade guiding (Fig. 14)
The sawblade guiding (4) is adjusted with the fixing
button (13).
The upper sawblade guiding can be set from 0 to 175
mm work piece height.
A clearance as small as possible to the work piece
ensures an optimum sawblade guiding and safe
working.
Back pressure bearings (Fig. 15+16)
The back pressure bearings (e) accept the feed pres-
sure of the work piece. Set the upper and lower back
pressure bearing in such a way that it slightly touches
the sawblade back. Tighten the screws (g). The dis-
tance should be 0.5 mm.

Upper guide rollers (Fig. 15)
Set the upper guide rollers (f) to the corresponding
sawblade width. The front edges of the guide roll-
ers must not exceed the tooth base of the sawblade.
When the guide rollers slightly touch the sawblade,
tighten the screws (g).
Lower guide rollers (Fig. 16)
Set the lower guide rollers (i) to the corresponding
sawblade width. The front edges of the guide roll-
ers must not exceed the tooth base of the sawblade.
When the guide rollers slightly touch the sawblade,
tighten the screws (h).
The sawblade must not jam!
Storing the push rod (Fig. 17)
In order to have the push rod (R) to hand at all times,
hang it on the device (j) intended for this, at the top
left side of your band saw.
8.10 Transverse cutting gauge (14)(optional) (Fig.
18)
• Slide lateral stop (o) into a groove (k) in the saw
bench.
• Release the grip screw (l).
• Turn the lateral stop (o) until the desired angular
dimension has been set. The arrow on the lateral
stop indicates the set angle.
• Retighten the grip screw (l).
• The stop rail (n) can be slid against the lateral
stop (o). To do so, loosen the knurled screws (m)
and slide the stop rail (n) into the desired position.
Tighten the knurled screws (m) again
• Attention! Do not slide the stop rail (n) too far in the
direction of the saw blade.
8.11 On/Off switch (Fig. 1)
• To turn the machine on, press the green button
„1" (10).
• To turn the machine off again, press the red but-
ton „0"(10).
• The band saw is equipped with an undervoltage
switch. With a power failure, the band saw must
be switched back on again.
Attention!
When working with the machine, all protective devic-
es and guards must be fitted.
The upper and lower bandwheel is protected by a
fixed guard and an articulated cover. When opening
the cover, the machine is switched off. Starting is
possible only with closed cover.
9. Transport
Caution: Pay attention to the weight of the machine
when lifting it and call upon the help of another person!
Use the transport equipment. Stand on the side of
the wheels. Pull the upper part of the machine to-
wards you so that the machine stands on the two
