In the event of a voltage failure an undervoltage
relay will trip. This prevents the machine from
starting up when the power is restored. To restart,
the green switch button must be pressed.
Housing door turn-lock fastener
Open and close the housing door using the turn-
lock fastener (4) (13) .

Open the housing door:
1. Turn the upper turn-lock fastener (4) approx.
one turn in clockwise direction and turn the
lower turn-lock fastener (13) about one turn in
anti-clockwise direction.
The housing door opens slightly. This activates
the door interlock which switches the motor off.
Danger from exposed bandsaw blades
and wheels!
If after one turn the motor does not switch off
or the door immediately opens wide, the door
interlock or the closure system is defective.
Shut down the saw and return it to the
Service Centre in your country for repair.
2. Continue to turn the turn-lock fasteners.
The housing door opens wide.
Close the housing door:
 Push against the housing door and turn the
upper turn-lock fastener in anti-clockwise direc-
tion and the lower turn-lock fastener in clockwise
direction until the stop.
The housing door touches the housing com-
pletely.
Setting knob for band saw blade tension
With the setting knob (21) the band saw blade
tension is corrected, if necessary:
 Turning the setting knob clockwise increases the
blade tension.
 Turning the setting knob counter-clockwise
reduces the blade tension.
21
Setting knob for blade tracking adjustment
With the setting knob (20) the tilt of the upper
band saw wheel can be adjusted, if necessary.
This tracking adjustment is required to have the
blade run dead centre on the rubber tyres of the
band saw wheels:
 turning clockwise = blade moves to the rear
 Turning counter-clockwise = blade moves to the
front.
20
Setting knob for drive belt tension
With the setting knob (14) the drive belt tension is
corrected, if necessary:
 turning the setting knob anti-clockwise reduces
the blade tension;
 Turning the setting knob clockwise increases the
blade tension.

Saw table tilt
After loosening the lock screw (31) the saw table
(11) tilts steplessly through 20 against the blade.

Rip fence
The rip fence (10) is clamped at the front side.
The rip fence can be used on both sides of the
blade.

7.1 Aligning the Saw Table
The saw table needs to be aligned in two planes
 laterally, in order for the blade to run dead centre
through the table insert;
 at right angles to the band saw blade.
Saw table lateral alignment
1. Loosen the lock lever (32) and the hexagon
nut (33) .
32
Danger!
Risk of injury, even with the band saw blade
at standstill. To loosen and tighten the
fastening screws use a tool that allows for
keeping your hand at a sufficient distance
from the band saw blade.
2. Loosen the four fastening screws (34) .
34
3. Align saw table so that the blade runs through
the centre of the table insert's slot.
4. Tighten again the four fastening screws (34) .
5. Tighten the hexagon nut (33) only so much
that the saw table can still easily be tilted.
6. Tighten lock lever (32) .
Aligning the saw table at right angles to the
band saw blade
1. Raise upper blade guide fully ( see "opera-
tion").
2. Check band saw blade tension (see "Initial
operation").
3. Loosen the lock lever (32) .
4. Using a try square, set the table at right angles
to the blade and tighten the lock lever (32)
again.
5. Loosen the lock nut (35) and adjust the limit
stop screw (36) until it barely touches the saw
housing.
