Mains Connection - Metabo BKS 400 Plus Operating Instructions Manual

8. Screw in or unscrew the 45-degree
set screw (48) until the mitre fence
stops at an angle setting of precise-
ly 45°. The 45-degree line on the
angle scale must point to the zero
line on the nonius scale (49).
9. Tighten the 45-degree set screw
(48).
6.4 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 (51)
and one hexagon nut (50) 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
48
– The surfaces of the table extension
49
and saw table must both be in the
same plane.
Swinging the table extension down
1. Unscrew and remove the hexagon
head screws (51) 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
illustrated. Set the table extension
supports down on the lower cross-
struts of the saw table.

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.
– Use only rubber-insulated extension
cables with sufficient cross sections
50
(see 'Technical Data').
– Do not pull on mains cord to unplug.
B
High voltage!
Operate saw in dry environment only.
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.
ENGLISH
– 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.

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 max-
imum 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! (only possible for version with
DC motor)
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.
3
Note:
The humming noise after switch-off
arises due to the electronic motor brake
response. It is not a machine fault!
3. Check the saw blade's direction of
rotation from the left-hand side of
the saw. The saw blade must rota-
te clockwise.
