6.2 Mount saw
For a safe stand, the saw has to be fixed on a
stable base.
Mount on frame:
The frame (17), which is already prepared for
holding the saw, provides the optimum working
height and stand safety.
Caution!
Attach the frame to the saw the correct way round:
If the operator – in the working position – stands in
front of the saw, the height-adjustable foot (20) of
the frame must be located at the front right.
The assembly instructions for the frame can be
found on on the penultimate page of this
operating manual.
Fasten to work bench:
1. Drill four holes in the supporting surface.
2. Put fixing bolts through the base plate and
secure with nuts.
6.3 Installing the Saw Table
1. Guide saw table (14) over the saw belt and
place on the saw table guide.
2. Fasten saw table to the saw table guide with
four screws (22) and washers - do not tighten,
align the saw table first (See chapter 6.4).
6.4 Aligning the Saw Table
The saw table needs to be aligned in two planes
– laterally so that the belt runs accurately in the
middle of the table insert;
– at right angles to the band saw blade.
Saw table lateral alignment
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.
1. Align saw table (14) such that the saw belt is
located in the middle of the table insert (15).
2. Tighten the four fastening screws (22).
Aligning the saw table at right angles to the
band saw blade
1. Position the blade guide (39) at the very top.
(For details see chapter 9.1).
2. Check saw belt tension. (For details see
chapter 8.2).
3. Release both clamping levers (21).
4. Turn the setting knob (23) to adjust the saw
table (14) horizontally - turn to the stop.
5. Retighten both clamping levers (21).
6. Use a bracket to check whether the saw table
is perpendicular to the band saw blade.
If the saw table is not perpendicular to the band
saw blade, please adjust the end stop screw (24)
as follows:
1. Release both clamping levers (21).
2. Use a hexagon key to turn the end stop screw
(24) through the hole (13) in the saw table
anticlockwise.
3. Use a bracket to align the saw table
perpendicular to the band saw blade and
retighten both clamping levers (21).
4. Use a hexagon key to turn the end stop screw
(24) through the hole (13) in the saw table
clockwise until the end stop screw (24)
touches the saw housing.
6.5 Mount carry handles
Tighten the two carrying handles (9) using the
screws supplied.
6.6 Installing the fence guide extrusion
 Fasten fence guide extrusion (25) to the saw
table using four wing nuts and washers.
6.7 Fit fence guide extrusion
The rip fence (26) can be fitted both on the left or
the right of the band saw blade. If the rip fence
should be moved from side to the other, the profile
rails (28) should be placed on the other side.
Clamping the rip fence
1. Lock rip fence in the rear table edge.
2. Place the rip fence at the front on the fence
guide extrusion (25).
3. Fasten rip fence by pushing the clamping lever
(29) down.
Attach profile rails to the other side
1. Unscrew knurled screws (27).
2. Remove profile rails (28) together with the
fastening screws.
3. Insert profile rails (28) together with the
fastening screws from the other side.
4. Screw on knurled nuts (27) and tighten.
6.8 Fit table widener/extension
The table widener/extension (31) can be fitted
both to the right and the back of the saw table (14).
1. Unscrew stop screws (30) on the guide rails of
the table widener/extension.
2. Push guide rails fully into the holders under the
saw table.
3. Retighten the stop screws (30) in the guide
rails.
4. Slide table widener/extension to the desired
position and fasten with the knurled screws.
6.9 Transport
Position upper blade guide (39) at the very bottom.
(For details see chapter 9.1).
Remove projecting accessories.
Do not lift or transport the saw at the safety
installations.
Transport the saw with the help of another person.
Tilt the saw on the transport handles (9) and then
move on the transport rollers (19).

7. Machine Details

Note:
In this chapter the essential operating elements of
the machine are introduced.
The proper use of the machine is described in
chapter "Operation". Read this chapter before
using the saw for the first time.
ON/OFF Switch
 Switching on = Press green switch (2).
 Switching off = Press red switch (3).
Restart protection: An under-voltage relay is
triggered if the electricity fails. 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
Use the turn-lock fastener (5) to open and close
the housing door.
Opening the upper/lower housing door:
1. Rotate the turn-lock fastener (5) several
revolutions in an anti-clockwise manner.
The housing door opens slightly. This
activates the door interlock which switches the
motor off.
Danger from exposed band saw
blades and wheels!
If the motor does not switch off immediately
after opening the door or if the door opens
immediately, the door locking mechanism or
the locking system is defective. Shut down the
saw and return it to the Service Centre in your
country for repair.
2. Rotate turn-lock fastener (5) further
anticlockwise.
The housing door opens wide.
Closing the upper/lower housing door:
 Press housing door and rotate turn-lock fastener
(5) clockwise until the housing door shuts
cleanly.
Setting knob for band saw blade tension
If necessary, the tension of the band saw blade
can be corrected using the setting knob (32). (For
details see chapter 8.2).
Quick release lever
The quick release lever (34) can be used to
release the band saw blade, e.g. to replace the
blade.
Setting knob for angle of the upper band saw
roller (setting the run of the saw blade)
With the setting knob (43) the angle of the upper
band saw blade roller can be changed if required.
By adjusting the angle, the band saw blade is
aligned such that it runs in the middle of the plastic
tyres of the band saw blade rollers. (For details see
chapter 10.2).
Speed adjustment
By turning over the drive belt, the band saw blade
can be operated with two speed levels (see
"technical specifications"). (For details see chapter
9.2).
Setting knob for drive belt tension
The setting knob (40) can be used, if necessary, to
correct the tension of the drive belt. (For details
see chapter 9.2).
Saw table tilt
After releasing both clamping levers (21) the saw
table (14) can be tilted smoothly up to 45° against
the band saw blade by turning the setting knob
(23).
Rip fence
The rip fence (26) is clamped to the front and is
also held in place with the hold-down clamp on the
back of the saw table. The rip fence can be used
on both sides of the blade. (For details see chapter
6.7).
Mitre fence
The mitre fence (35) is inserted into the groove in
the saw table from the front.
For mitre cuts the mitre fence turns to 60° in both
directions.
For 45° and 90° mitres positive stops are provided.
To adjust an angle: Release the clamping handle
(36) by turning it anticlockwise.
Risk of injury!
The clamping handle (36) must be tight when
sawing with mitre fence.
The attachment profile can be moved or removed
by loosening the knurled nuts.
Store mire fence (35) in the holder (18) when not
in use.

8. Initial Operation

Danger!
Start the saw only after the following
preparations have been completed:
– the saw is securely mounted;
– the saw table is installed and aligned;
– Drive belt tension checked;
– the safety devices checked.
Connect the saw to the mains supply only
after all of the above preparations are
completed! Otherwise there is a risk of an
unintentional starting of the saw, which may
cause serious personal injury.
8.1 Connect chip extraction
Danger!
Some types of sawdust (e.g. from oak, beech
and ash) can cause cancer if inhaled: Only
work in a closed room with a dust collector
(air speed at the extraction outlets of the saw
>= 20 m/s).
Caution!
Operation without a dust collector is only
possible:
– outdoors;
– for short use (up to max. 30 minutes);
– with dust respirator.
