2. To change the position of the parallel stop (6), slide
the parallel stop (6) with an opened clamping lever
(33) along the guide rail (7).
3. In order to fix the parallel stop (6) in the desired
position, press the clamping lever (33) down fully.
9.8 Fitting the handwheel for adjusting the cut-
ting speed (Fig. 2, 3, 15)
The speed of the band saw can be infinitely adjusted
using the hand wheel.
1. Slide the hand wheel for adjusting the cutting
speed (9) onto the shaft on the right side of the
machine.
2. Secure the handwheel for adjusting the cutting
speed (9) with a washer (43) and the locknut (42).
3. Tighten the nut (42).
9.9 Push rod retainer (Fig. 2, 17)
The push stick retainer (16) is pre-mounted on the
machine frame. If not in use, the push stick (52) must
always be stowed in the push stick retainer (16).
9.10 Changing the saw band (Fig. 1, 2, 7, 17, 18,
19, 20) m Attention: Pull out the mains plug!
Danger! Risk of injury even when the saw band
is at a standstill. Wear gloves when replacing the
saw band.
Only use suitable saw bands. The guide rail (7) can be
swivelled to the side to make replacing the saw band
easier.
1. Loosen the wing screws (35). But do not unscrew
them all the way. (Fig. 7)
2. Carefully pull the guide rail (7) out from the front
and swivel to the right. (Fig. 3, 7)
3. Open the housing door (2) by unfastening the two
door locks (3 and 8). (Fig. 1)
4. Swivel the door arrester (34) inwards in order to
hold the door open. (Fig. 7)
5. Set the saw band tension quick clamp lever (15) to
"-". (Fig. 2, 17)
6. Turn the adjusting knob for saw belt tension (1) an-
ti-clockwise until the saw band (26) is tensioned.
(Fig. 2, 17)
7. Open the saw band guard (4) by folding it down to
the right. (Fig. 7, 19)
8. Remove the saw band (26) by taking it off from the
saw band rollers and through the slot in the saw
table (24).
9. Install a new saw band (26) in reverse order, mak-
ing sure that the new saw band is centred on both
saw band rollers. The teeth of the saw band must
point downwards in the direction of the saw table.
10. Turn the adjusting knob for saw belt tension (1)
clockwise until the saw band (26) lightly tensioned.
11. Set the saw band tension quick clamp lever (15) to
"+". (Fig. 2, 17)
12. Turn the adjusting knob for saw belt tension (1) clock-
wise until the pointer of the scale is in the correct ten-
sion range. The tension range depends on the tech-
nical data of the saw band. Excessively high tension
leads to premature breakage of the saw band!
13. Fold the door arrester (34) up again. (Fig. 7)
14. Close the housing door (2) by locking the two door
locks (3 and 8) again.
9.11 Setting the run of the saw blade (Fig. 2, 20)
The saw band should run centrally on both band
wheels.
1. Loosen the wing screw (17). (Fig. 2)
2. The incline of the top band wheel can be adjusted
using the adjusting knob (28):
– Turn the adjusting knob (28) clockwise if the saw
band runs against the front of the saw. (Fig. 2)
– Turn the adjusting knob (28) anti-clockwise if the
saw band runs against the back of the saw.
3. Tighten the wing screw (17) after the adjustments
have been made. (Fig. 2)
m Attention! The band wheel must run over the cen-
tre of the band wheel after multiple turns. Visual in-
spection!
9.12 Adjusting the saw band guide (Fig. 2, 17)
You can adjust the top saw band guide (5) with the
help of the adjustment handle on the saw band guard
(27) from 0-205 mm in terms of workpiece height. The
smallest possible distance to the workpiece ensures
optimal belt guidance and safe working.
9.12.1
The counterpressure bearings (31) absorb the feeding
pressure of the workpiece.
Adjust the position of the counter-pressure bearings
(distance between counter-pressure bearing and saw
band = 0.5 mm - when moving the saw band by hand,
the saw band must not touch the support roller).
