•
work step.
6.1

Setting up the machine

Place the machine on a firm, level
•
floor.
To align the table surface horizontal-
•
ly, compensate for unevenness or
slippery floor surfaces using suitable
materials. Then check that the ma-
chine is stable.
The area around the circular saw
•
should be free of obstacles and trip-
ping hazards.
Ensure there is sufficient space to
•
handle larger workpieces.
For maximum upright stability the saw
can be bolted to the floor:
1. Place the fully assembled saw at a
suitable site and mark the bore
holes on the floor.
2. Move saw aside and drill the holes.
3. Align saw with the holes and bolt to
the floor.
A
Risk of injury by inhaling
wood dust!
Always connect a dust collector to
the saw if operating the saw in
closed rooms.
6.2 Table extension
3
Note:
The table extension supports must be
firmly screwed to the saw table.
Screwing on the table extension
1. Stick the angled ends of the sup-
ports into the slots in the cross-struts
on the rear of the saw and push
them outwards.
2. Screw the supports to the struts us-
ing one hexagon head screw (48)
and one hexagon nut (47) for each
as illustrated.

Tightening the screwed connections
Check all screwed connections of the
saw. Tighten the screwed connections
hand-tight using a suitable tool.
When tightening the screws, bear in
mind the following:
– The machine must be secure and
horizontal after the screws have
been tightened.
Aligning the table extension
– The surfaces of the table extension
and saw table must both be in the
same plane.
Swinging the table extension down
1. Unscrew and remove the hexagon
head screws (48) on both ends of
the supports. Store the screws and
nuts.
2. Slide the lower ends of the supports
towards each other.
3. Unhook the supports and carefully
swing the table extension down as il-
lustrated. Set the table extension
supports down on the lower cross-
struts of the saw table.
6.3

Mains connection

Mains cable:
– 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.
– Connect the machine to the power
supply using a suitable plug connec-
tion.
– Use only rubber-insulated extension
cables with sufficient cross sections
(see 'Technical Data').
47
– Do not pull on mains cord to unplug.
B
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 must be properly installed,
earthed and tested.
– Outlets must have neutral wires for
3-phase DC.
– The supply voltage and frequency
must match the data given on the
machine's nameplate.
– Protection against electric shock by
a residual current device (RCD) of
30 mA sensitivity.
– Use a max. 16A mains fuse (short-
circuit protection device) for short-
circuit protection.
– Unplug the power plug from the out-
let to disconnect it from the power
supply.

Note:
Please contact your Electricity Board or
qualified electrician if you are unsure of
whether your house supply fulfils these
requirements.

Note:
Due to the high start-up current of the
motor during switch-on mains voltage
fluctuations may occur - these can be
recognised through, e.g., temporarily
flickering lights. In this case the mains
connection point has a higher im-
pendance than the recommended maxi-
mum value (see 'Technical Data').
Please contact your Electricity Board or
qualified electrician to have the connec-
tion point inspected.
A
Changing the direction of rota-
tion!
Depending on the phase sequence it
is possible that the motor will turn in
the wrong direction. This can lead to
the piece of wood being hurled away
when an attempt is made to make a
cut. Therefore the rotational direc-
tion must be checked every time the
machine is connected to a different
outlet.
Checking the direction of rotation:
1. Install machine ready for work and
connect it to the mains.
2. Start machine and immediately turn
OFF again.
