9.3 Adjust the band saw blade (6)
(Fig. 11)
ATTENTION
Before it is possible to implement the band saw blade
setting, the band saw blade must be tensioned correctly.
1. Open the housing doors (11) by loosening the Allen
screws (11b). Use a 5 mm Allen key (D).
2. Turn the top band wheel (23) clockwise slowly. The
band saw blade (6) must run in the centre on the run-
ning surfaces (24) of the top band wheel (23).
If this is not the case, correct the angle of the top band
wheel (23).
3. To do this, open the wing nuts (12a).
– If the band saw blade (6) runs more towards the
rear edge of the band wheel (23), then the adjust-
ment handle (12) must be rotated anti-clockwise.
– If the band saw blade (6) runs more towards the
front edge of the band wheel (23), then the adjust-
ment handle (12) must be rotated clockwise.
4. After setting the top band wheel (23), check the posi-
tion of the band saw blade (6) on the bottom band
wheel (25).
5. Turn the bottom band wheel (25) slowly by hand to
check the position of the band saw blade (6).
6. The band saw blade (6) should be positioned in the
centre on the running surfaces (24) of the bottom
band wheel (25). If this is not the case, the angle of
the top band wheel (23) must be adjusted again.
7. To ensure that the adjustment of the top band wheel
(23) influences the position of the band saw blade (6)
on the bottom band wheel (25), turn the bottom band
wheel (25) several times.
8. Retighten the wing nut (12a).
9. Once the adjustment is complete, close the housing
doors (11) again and secure them with the Allen
screws (11b). Use a 5 mm Allen key (D).
9.4 Adjusting the band saw blade
guide (Fig. 1, 11, 12, 13, 14, 15)
• The support bearings (27) must be readjusted before
initial start-up and after every band saw blade change.
• The rear and lateral band saw blade guide is adjusted
using eccentric support bearings (27a, 27c, 27e, 27g).
These eccentric support bearings (27a, 27c, 27e, 27g)
enable precise fine adjustment of the position and
alignment of the band saw blade (6) to improve the
accuracy and performance of the product.
1. Open the housing doors (11) by loosening the Allen
screws (11b). Use a 5 mm Allen key (D).
9.4.1 Rear upper support bearing (27a)
(Fig. 12)
The rear upper support bearing (27a) absorbs the feed
pressure of the workpiece.
1. Loosen the grub screw (27b) of the upper support
bearing (27a). Use the 3 mm Allen key (B).
2. Turn the rear upper support bearing (27a) until it just
no longer touches the band saw blade (6) (max. dis-
tance 0.5 mm).
Ensure that the rear upper support bearing (27a) is
centred in relation to the band saw blade (6).
3. Retighten the grub screw (27b) of the rear upper sup-
port bearing (27a). Use the 3 mm Allen key (B).
9.4.2
The rear lower support bearing (27e) absorbs the feed
pressure of the workpiece.
1. Loosen the grub screw (27f) of the rear lower support
bearing (27e). Use the 3 mm Allen key (B).
2. Turn the rear lower support bearing (E) until it just no
longer touches the band saw blade (6) (max. distance
0.5 mm).
Ensure that the rear lower support bearing (27e) is
centred in relation to the band saw blade (6).
3. Retighten the grub screw (27f) of the rear lower sup-
port bearing (27e). Use the 3 mm Allen key (B).
9.4.3
Ensure that the top retainer (28) is in a horizontal position
and the top support bearing (27) is centred in relation to
the band saw blade (6).
1. Loosen the screw (28a) of the top retainer (28) and
align the top retainer (28) with the band saw blade (6).
Use a Phillips screwdriver or the open-end spanner
WAF 8/10 (A).
9.4.4
The lateral support bearings (27c, 27g) serve to stabilise
and align the band saw blade (6) during operation. They
help to ensure that the band saw blade (6) remains in the
correct position and track during the cutting process.
1. Loosen the grub screws (27d) of the upper lateral sup-
port bearings (27c).
Use the 3 mm Allen key (B).
2. Turn the upper lateral support bearings (27c) until
they just no longer touch the band saw blade (6)
(max. distance 0.5 mm).
Ensure that the upper lateral support bearings (27c)
are centred in relation to the band saw blade (6) and
parallel to each other.
3. Retighten the grub screws (27d) of the upper lateral
support bearings (27c).
Use the 3 mm Allen key (B).
9.4.5
To adjust the lower lateral support bearings (27g), it may
be necessary to tilt the saw table (8) to 45°. (See 10.4)
1. Loosen the grub screws (27h) of the lower lateral sup-
port bearings (27g).
Use the 3 mm Allen key (B).
2. Turn the lower lateral support bearings (27g) until they
just no longer touch the band saw blade (6) (max. dis-
tance 0.5 mm).
Ensure that the lower lateral support bearings (27g)
are centred in relation to the band saw blade (6) and
parallel to each other.
