6.3 Connection of a Dust
Collector
A
Danger!
Some types of wood dusts
(e.g. beech, oak, ash) may cause can-
cer when inhaled. Use a dust collec-
tor:
−
when using the saw in enclosed
spaces;
−
when using the saw over
extended periods (more than 1/2
hour per day);
−
when cutting oak, beech or ash.
The dust collector must comply with
the following requirements:
−
fitting the dust extraction port
diameter (43 mm);
−
air flow volume
≥
550 m
3
/h;
−
vacuum at the dust extraction
port of the saw
≥
740 Pa;
−
air speed at the dust extraction
port of the saw
≥
20 m/ s.
Observe and follow the dust collector's
operating instructions as well!
6.4 Adjusting the Riving
Knife
3
Note:
The riving knife is factory-set to
the lower position. An alignment before
initial operation is only necessary if the
riving knife's position has changed dur-
ing transport or the maximum depth of
cut is required.
1. Raise the upper saw table fully and
tighten the depth of cut lock screws.
2. Checking the riving knife:
−
Distance between the saw
blade's outer edge and the riving
knife must be 3 – 8 mm.
−
The riving knife must be in align-
ment with the saw blade.
A
Danger!
The riving knife is one of the
safety devices and must be correctly
installed for a safe operation.
Only if realignment of the riving knife is
necessary:
3. Loosen hexagon socket screws
(39) .
4. Adjust riving knife (40) to desired
position: Distance between the saw
blade's outer edge and the riving
knife must be 3 – 8 mm.
5. Tighten hexagon socket screws
(39) .

Note:
When the riving knife is set to its
upper position the rip fence can only be
placed over the blade guard when the
upper saw table is fully raised.
6.5 Connection to AC Power
B
Danger! High voltage
•
Operate this machine in dry sur-
roundings only.
•
Operate the machine only on a
power source meeting the follow-
ing requirements (see also "Tech-
nical specifications"):
−
mains voltage and system fre-
quency conform to the voltage
and frequency shown on the
machine´s rating label;
−
fuse protection by a residual
current operated device (RCD)
of 30 mA sensitivity;
−
outlets properly installed,
earthed, and tested.
•
Position power supply cable so it
does not interfere with the work
and is not damaged.
•
Protect power supply cable from
heat, aggressive liquids and
sharp edges.
•
Use only rubber-jacketed exten-
sion cables of sufficient lead
cross-section (3 x 1.5 mm
2
).
•
Do not pull on power supply
cable to unplug.
7.1 Safety Devices
Retractable blade guard
The retractable blade guard (41) pro-
tects against accidental contact with the
saw blade and from chips flying about.
The retractable blade guard must always
return automatically into its starting posi-
tion when the sawhead is lifted: When
the sawhead is in the starting position
the saw blade must be covered all
around.
Safety lock
The safety lock (42) locks the sawhead
in the upper position and prevents that
the retractable blade guard exposes the
saw blade.
The safety lock is released by pressing
on it. The sawhead can now be lowered;
when the sawhead is lowed the retracta-
ble blade guard is retracted, exposing
the saw blade.
After the cut is made - and the sawhead
is in its upper starting position - the
retractable blade guard is locked again
by the safety lock.
7.2 Setting Up
A
Danger!
Before the machine is set up:
1. turn machine OFF,
2. unplug,
3. wait until the machine has come
to a complete stop.
