7. Raise saw blade fully.
8. Install blade guard on the riving kni-
fe.

Note:
The blade guard should be tilted slightly
downward on the operator side after
being correctly installed on the riving
knife.

Note:
If you are working with a dust collector,
you should now connect the dust ex-
traction port (60) on the saw blade en-
closure to the dust collector.

Mains connection

B
Danger! High voltage
Operate saw in dry environment on-
ly.
Operate saw only on a power source
matching the following requirements
(see also 'Technical Data'):
– Outlets properly installed,
earthed, and tested.
– three-phase outlets with neutral
wire installed;
– Mains voltage and system fre-
quency conform to the voltage
and frequency shown on the ma-
chine's rating label.
– Protection against electric shock
by a residual current device
(RCD) of 30 mA sensivity.
– Fuse protection of 16 A maximum
against short circuits.
– System impedance Z
max.
house service connection: see
separate supplementary sheet.

Note:
Contact your Electricity Board or a qua-
lified electrician if you are not sure if
your house service connection meets
these requirements.
Make sure that the mains cable is

out of the way so that it does not in-
terfere with the work and cannot be
damaged.
 Protect mains cable from heat, ag-
gressive liquids and sharp edges.
 Use only rubber-insulated extension
cables with sufficient cross sections
(see 'Technical Data').
 Do not pull on mains cord to unplug.
B
Changing the direction of ro-
tation! 
(only possible for version with
DC motor)
Depending on the wiring of the elec-
trical connection the saw blade may
rotate the wrong way. This can lead
to the workpiece being hurled away
when attempting to make a cut. The
direction of rotation must therefore
be checked every time the saw is
connected to another outlet. In case
of an incorrect direction of rotation,
the wiring of the outlet must be
changed by a qualified electrician:
1. After the saw and all of its safety
devices have been assembled, con-
nect it to the mains supply.
2. Raise saw blade fully.
3. Start saw and switch OFF immedia-
tely.
4. Check the saw blade's direction of
rotation from the left-hand side of
the saw. The saw blade must rotate
clockwise.
5. If the saw blade rotates anticlockwi-
se, unplug the power cable at the
saw.
6. Have the electric supply changed
by a qualified electrician!

Operation

A
at the
Risk of injury!
This saw may only be operated by
one person at a time. Other persons
shall stay only at a distance to the
saw for the purpose of feeding or re-
moving stock.
Before starting work, check to see
that the following are in proper wor-
king order:
– mains cable and plug;
– ON/OFF switch;
– riving knife;
– blade guard; and
– feeding aids (push stick, push block
and handle).
Use personal protection gear:
– dust mask;
– ear protection; and
– safety goggles.
Assume proper operating position:
– in front of the saw on the operator
side;
– in front of the saw;
– to the left of the line of cut; and
– if work is being carried out by two
persons, with the other person re-
maining at an adequate distance to
the saw.
If the type of work requires it, use
the following:
