7.1

Sawing

1. Choose and install a table insert
extrusion suitable for the type of cut
to be performed:
 table insert extrusion with a
narrow slot for standard cross
cuts only;
 table insert extrusion with bev-
elled slot for bevel cuts also.
2. Adjust the band saw blade speed.
3. If necessary, adjust the table tilt.
A
Risk of kickback (work piece is
caught by the band saw blade and
thrown against the operator)!
Do not jam any work pieces.
4. Select rip fence and table tilt for the
type of cutting operation to be car-
ried out.
A
Hazard due to jamming of the
tool!
When cutting with the ripping fence
and inclined workpiece, the ripping
fence has to be mounted at the side
of the workpiece inclined down-
wards.
5. Set upper blade guide 3 mm above
the work piece.
Note: 
3
Always make a trial cut in a piece
of scrap to verify settings; correct if nec-
essary before cutting the work piece.
6. Place work piece on the saw table.
7. Plug in.
8. Start saw.
9. Cut work piece in a single pass.
10. Switch off if no further cutting is to be
done immediately afterwards.

8. Care and Maintenance

Danger! 
A
Prior to all servicing:
1. Switch machine OFF;
2. Wait until the saw has come to a
complete stop.
3. Unplug power cable;
 Check to see that all safety devices
are operational again after each ser-
vice.
 Replace defective parts, especially
of safety devices, only with genuine
replacement parts. Parts not tested
and approved by the manufacturer
can cause unforeseen damage.
 Repair and maintenance work other
than described in this section should
only be carried out by qualified spe-
cialists.
8.1 Changing the Band Saw
Blade
Danger! 
A
Risk of injury, even with the
band saw blade at standstill. Wear
gloves when changing blades. 
Use only suitable band saw blades
(see "Technical Specifications").
1. Loosen the four thumb screws (71)
and remove the fence guide extru-
sion (72).

2. Open both housing doors.
3. Swing the lower blade guard open.
4. Set the upper blade guide (73) to its
lowest position.
5. Loosen quick release lever (74) until
the band saw blade has slackened.
6. To remove the band saw blade,
guide it through
 the slot in the saw table (75),
 the blade guard on the upper
blade guide (76),
 the blade cover on the saw
housing (77) and
 the blade guides.

ber tyres of the band saw wheels.
9. Tighten quick release lever until
blade does no longer slip off the
band saw wheels.
10. Close lower blade guard .
Danger! 

Close housing doors only
when the lower blade guard is in its
closed position.
11. Close both housing doors.
12. Then:
 tension band saw blade (see

 align band saw blade (see
"Care and Maintenance");
 align blade guides (see "Care

 let saw test run for at least one
minute;
 stop saw, unplug and recheck
settings.
8.2 Aligning the Band Saw
Blade
If the band saw blade does not run in the
centre of the rubber tyres, the tracking
needs to be corrected by adjusting the tilt
of the upper band saw wheel:
1. Loosen lock nut (78).
2. Turn setting knob (79):
 Turn setting knob (79) clock-
wise if the band saw blade
runs towards the front of the
saw.
 Turn setting knob (79) coun-
ter-clockwise if the band saw
blade runs towards the rear of
the saw.

3. Tighten lock nut (78).
8.3 Aligning the Upper Blade
Guide
