– 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.

– If no dust collector is used chips will
accumulate, which need to be removed
periodically.
Connect duct collector or industrial vacuum
cleaner with appropriate adapter to the chip
extraction nozzles (16).
8.2 Tighten band saw blade
Danger!
Too much tension can cause the band saw
blade to break. Too little tension can cause the
driven band saw wheel to slip and the band
saw blade to stop.
1. Quick release lever (34) must be in the "Tight
band saw blade" position.
2. Move upper blade guide (39) to the very top.
(For details see chapter 9.1).
3. Check band saw blade tension: Check setting
on the display for the band saw blade tension
(33). The scale indicates the correct
adjustment depending on the band saw blade
width.
4. Correct tension if necessary:
– Turning the setting knob (32) clockwise
increases the tension.
– Turning the setting knob (32) anticlockwise
reduces the tension.
8.3 Connection to Power Mains
Danger! High voltage
Operate the saw in only in a dry
environment.
Operate the saw only on a power source
matching the following requirements (see
also "Technical Specifications"):
– Mains voltage and system frequency must
conform to the voltage and frequency
shown on the machine´s rating label;
– Protection with an FI switch with an
residual current of 30 mA;
– outlets properly installed, earthed and
tested;
– three-phase outlets with neutral wire
installed;
Note:
Check with your local Electricity Board or your
electrician if in doubt whether your house service
connection meets the requirements.
Make sure the power supply cable is out of
the way, so that it does not interfere with
the work and does not pose a tripping
hazard or will get damaged.
Protect the power supply cable from heat,
aggressive liquids and sharp edges.
Only use rubber cables with a sufficient
cross section (3 x 1.5 mm2 as extension
cables, for design with three-phase motor: 5
x 1.5 mm2).
Do not pull on the power supply cable to
unplug.
Change in direction of rotation (only
for design with three-phase motor):
Depending on phase sequence the band saw
blade may turn in the wrong direction. This
can cause the work piece being tossed away
when attempting to cut. Therefore, always
check direction of rotation after every
connection to the power supply.
In the case of wrong direction of rotation, the
connection must be changed by an
electrician!
1. When the saw is assembled and all safety
devices are installed, connect it to the power
supply.
2. Start saw briefly and turn OFF immediately
again.
3. Note direction of rotation of the band saw
blade: The band saw blade must move
from top to bottom in the cutting area.
4. If the band saw blade turns in the wrong
direction, unplug the power supply cable at the
saw.
5. Have the electrical connection changed by a
qualified electrician!
Danger!
To reduce the risk of personal injury as much
as possible, the following safety
recommendations should be observed when
operating the saw.
Use personal protection gear:
– dust respirator;
– ear protection;
– safety goggles.
Cut only one work piece at a time.
Always hold the work piece down on the
table.
Do not jam any work pieces.
Do not try to slow the band saw blade down
or stop it by pushing the work piece against
the saw blade from the side.
If the type of work requires, use the
following:
– Push stick – if the distance to the stop
profile – band saw blade <=120 mm;
– work support – for long stock, which
would otherwise fall off the table on
completion of the cut;
– dust collector;
– an appropriate jig when cutting round
stock, to keep it from turning;
– a suitable guide for firm support when
cutting thin stock laid on edge.
Before starting work, check to see that the
following are in proper working order:
– Band saw blade;
– upper and lower blade guard.
Replace damaged parts immediately.
Assume correct work position (the band
saw blade's teeth must point towards the
operator).
Never cut several work pieces at the same
time – and also no bundles containing
several individual pieces. Risk of personal
injury if individual pieces are caught by the
saw blade uncontrolled.
Entangelement hazard!
Do not wear loose clothing, jewellery, or
gloves, which may get caught and wound
up by revolving machine parts.
Contain long hair with a hairnet.
Never cut stock to which ropes, cords,
strings, cables or wires are attached or
which contain such materials.
9.1 Set height of the blade guide
The height of the upper blade guide (39) must be
set:
– before each sawing procedure, to adjust to the
height of the work piece (the upper blade
guide (39) must be approx. 3 mm above the
work piece during cutting);
– after adjustments of band saw blade or saw
table (e.g. band saw blade change, tensioning
of the band saw blade, saw table alignment).
Danger!
Before adjusting the upper blade guide and
saw table tilt:
– switch machine OFF;
– wait until the band saw blade has come to
a complete stop.
1. Release lock nut (38).
2. Turn setting knob (37) so that the upper blade
guide (39) is approx. 3 mm above the work

9.2 Set band saw speed
1. Unplug power cable;
2. Open the lower housing door.
3. Loosen drive belt by turning the setting knob
(40) clockwise.
4. Place drive belts on the corresponding puller
on the drive wheel (lower blade roller) and on
the corresponding motor pulley – Note sticker
on the inside of the lower housing door.
Caution!
The drive belt must run either on the two front
or the two rear pulleys. Never place drive belt
diagonally because otherwise it sill be
damaged!
– Drive belt on front pulleys
= low speed, high torque (for hard wood,
plastics and non-ferrous metals (with
corresponding blade).
– Drive belt on back pulleys
= high speed, low torque (for all woods).
5. Retighten drive belt by turning the setting knob
(40) anticlockwise (it must be possible to push
the drive belt down about 10 mm in the middle
between the rollers).
6. Close the lower housing door.
