4.
Loosen setting knob (63) until the
band saw blade has slackened.
5.
To remove the band saw blade,
guide it through
 the slot in the saw table ,
 the blade guard on the upper
blade guide (64),
 the blade cover on the saw hous-
ing (65) and
 the blade guides.
6.
Fit a fresh band saw blade. Observe
correct position: the teeth point
towards the front (door) side of the
saw.
7.
Center band saw blade on the rub-
ber tyres of the band saw wheels.
8.
Tighten setting knob until blade does
no longer slip off the band saw
wheels.
9.
Close both housing doors.
10. Then:
 tension band saw blade (see "Ini-
tial operation");
 align band saw blade (see "Care
and Maintenance");
 align blade guides (see "Care and
maintenance");
 let saw test run for at least one
minute;
 stop saw, unplug and recheck
settings.
11. Finally reinstall the fence guide
extrusion for the rip fence.

Tensioning the Band Saw
Blade
Danger! 
A
Too much tension can cause
the band saw blade to break. Too lit-
tle tension can cause the driven band
saw wheel to slip and the band saw
blade to stop.
1.
Raise upper blade guide fully (see
"Operation").
22
2.
Check tension by pushing with a fin-
ger, halfway between table and
63
upper blade guide, against the side
of the blade. The blade should flex
not more than 3-5 mm.
3.
Correct tension if necessary:
 turning the setting knob (66)
counter-clockwise increases the
blade tension.
 turning the setting knob (66)
counter-clockwise reduces the
blade tension.

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 (67).
2.
Turn setting knob (68):
 Turn setting knob (68) clockwise
if the band saw blade runs
towards the front of the saw.
 Turn setting knob (68) counter-
clockwise if the band saw blade
runs towards the rear of the saw.
3.
Tighten lock nut (67).
9.4
Aligning the Upper Blade
Guide
The upper blade guide consists of:
 a thrust bearing (supporting the band
saw blade from the rear),
 two guide bearings (providing lateral
support).
All bearings need to be readjusted after
every band saw blade change and/or
tracking adjustment.
3
wear, if necessary replace both guide
bearings at the same time.
Adjusting the thrust bearing
1.
If necessary, align and tighten the
band saw blade.
2.
Loosen fixing screw (69) of the
upper blade guide.
3.
Align upper blade guide
4.
Tighten the upper blade guide's fix-
ing screw.
66
5.
Loosen the thrust bearing's (71) lock
screw (70).
71
6.
Adjust thrust bearing position (dis-
tance thrust bearing - band saw
blade = 0.5 mm – if the band saw
blade is turned by hand, it must not
touch the thrust bearing).
7.
Tighten the thrust bearing lock
screw.
Adjusting the guide bearings
1.
Loosen knurled nut (73).
2.
Set guide bearings (74) with the
knurled thumb screws (72) against
the band saw blade.
67
68
3.
Turn band saw wheel by hand in a
clockwise direction several times to
bring the guide bearings in correct
position – both guide bearings
should just touch the band saw
blade.
4.
Retigthen knurled nut (73) to lock
the knurled thumb screw (72).
