− the saw band for its faultless condition
− that all doors are closed
− whether the pushstick is to hand
Do not use any deformed or damaged saw bands.

When the machine is not used open-air it must be
connected on both suction sockets with a splinter
extraction system (i.e. portable small dust extractor).

Start-up

Electric supply

Compare the voltage listed on the machine's type plate, e.g.
230 V, with the mains voltage and connect the machine to a
suited and and properly earthed electrical socket.
AC-motor
Use an electrical socket with a rated voltage of 230 V with a
fault-current circuit breaker (30 mA).
Main fuse: 10 A slow
Use an connecting or extension cable in compliance with IEC
60245 (H 07 RN-F) having a core cross-section of at least:
1.5 mm² for cable lengths up to 25 m
2.5 mm² for cable lengths over 25 m
ON/OFF switch
Do not use any device where the switch can not be
switched on and off. Damaged switches must be repaired
or replaced immediately by the customer service.
Switching on

1st variant: The driving belt is located on the front pulleys
lower speed 11 m/s (660 rpm).
2nd variant: The driving belt is located on the rear pulleys
higher speed 16 m/s (960 rpm).
Never locate the driving belt diagonally on the
pulleys.
5.
Swivel the motor the the right. The driving belt is
tensioned.
Make sure that the driving belt is not over-tensioned.
6. Retighten the hexagon socket screw (21).
Close the door (4).
Saw band selection
The saw band delivered by standard is suitable for wood and
most plastics.
Consider when selecting the saw band,
− that no edgeless or damaged saw bands are used.
− that the selection of the saw band and the number of
revolutions is suitable for the material to be cut.
Connect splinter extraction
In closed rooms work only with a splinter extraction
(air speeds at suction socket of the saw ≥ 20 m/sec.).
Sawing without splinter extraction only
for short-time service (up to 30 min.)
or with a protective mask
or open-air
If you do not connect splinter extractor sawdust will
concentrate which you have to remove regularly.
Connect sawdust extraction system or small dust
extractor with a suitable adapter to the sawdust suction socket.

Settings on the saw

Saw band tension
A too high stress can result in the break of the saw band.
A too less stress can result in the drive wheel sliding
through and then result in the stop of the saw band.
You can check the stress:
Put the saw band coping (12) completely upwards (see
„Adjustment of the saw coping" page 20) and press with the
finger in the middle between the saw table and the upper saw
coping transversally against the saw band
it shall only be possible to push the saw band in laterally by
1 – 2 mm.
With the adjusting wheel (1) the stress of the saw band
can be corrected.
