7.5 Adjusting the blade guide (Fig. 29-31)
Whenever you change the blade you must reset both
the support bearings (30 + 31) and the guide bearings
(32 + 29).
Undo the fasteners (13) and open the left side
cover (12).
7.5.1. Upper support bearing (Fig. 29-31)
Undo the screw (33).
Move the support bearing (30) so that it is
almost touching the blade (25). There should be
a gap of approx. 0.5 mm.
Re-tighten the screw (33).
7.5.2. Setting the lower support bearing (31)
(Figure 29/31)
Disassemble the saw table (15).
Disassemble the support bearing cover (39).
Adjust in the same way that the upper support
bearing was adjusted.
The blade (25) is only supported by the support
bearings (30 + 31) during cutting. When idle the
blade should not touch the ball bearings.
7.5.3. Setting the upper guide bearings (28)
(Figure 29-31)
Undo the screw (35).
Move the upper blade guide (11) so that there is a
gap of approx. 1 mm between the front edge of
the guide bearings (28) and the gullet of the blade
in front.
Re-tighten the screw (37).
CAUTION! The blade will be rendered useless if
the teeth touch the guide bearings while the
blade is running.
Undo the screws (37)
Move the two guide bearings (28) towards the
blade so that there is a gap of approx. 0.5 mm
between the guide bearings (28) and the blade
(25). (The blade must not jam.)
Re-tighten the screws (35).
Turn the upper blade pulley (8) several times in
a clockwise direction.
Check the setting of the guide bearings (28)
again and re-adjust if necessary.
7.5.4. Setting the lower guide bearings (29)
(Figure 30)
Disassemble the saw table (15) (see 7.2).
Undo the screw (40)
Move the mount (49) of the guide bearings (29)
so that there is a gap of approx. 1 mm between
the front edge of the guide bearings (29) and the
gullet of the blade in front.
Re-tighten the screw (40).

IMPORTANT! The blade will be rendered
useless if the teeth touch the guide bearings
while the blade is running.
Undo the screws (38)
Move the guide bearings (29) towards the blade
so that there is a gap of max. 0.5 mm between
the guide bearings (29) and the blade (25). (The
blade must not jam.)
Re-tighten the screws (38).
Turn the lower blade pulley (7) several times in
clockwise direction.
Check the setting of the guide bearings (29)
again and re-adjust if necessary.
7.6 Adjusting the upper blade guide (11)
(Fig. 1/32)
Undo the fixing handle (20).
Lower the blade guide (11) as close as possible
to the workpiece to be cut (the gap should be
approx. 2-3 mm).
Re-tighten the fixing handle (20).
Check the setting before each cut and re-adjust
if necessary.
7.7 Adjusting the saw table (15) to 90°
(Fig. 26,33)
Move the upper blade guide (11) to the top.
Undo the fixing handle (18).
Set the angle (d) between the blade (25) and the
table (15).
Tilt the saw table (15) by turning it so that the
angle between it and the blade (25) is precisely
90°.
Re-tighten the fixing handle (18).
Undo the screw (52) of the pointer of the dial
scale (16), set the pointer to exactly 0° and
tighten the screw (52) again.
No bracket included.
7.8 Selecting the blade
The blade supplied with the bandsaw is designed for
all-purpose use. When you select a blade you should
have regard to the following criteria:
Use a narrow blade to cut tighter radii than you
can with a wider blade.
Wide blades are used to saw straight cuts. This
is particularly important in cutting wood because
the blade has a tendency to follow the grain of
the wood and thereby deviate easily from the
cutting line.
Finely toothed blades provide smoother cuts but
are slower than coarse blades.
Important: Never use warped or lacerated blades!
