Danger! Electrical Hazard
Operate saw in dry environment only.
Operate saw only on a power source match-
ing the following requirements (see also
"Technical specifications"):
-
Fuse protection by a residual current oper-
ated device (RCD) of 30 mA sensitivity;
-
Outlets properly grounded;
-
Outlets for 3-phase circuits with neutral
lead.
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 cable of sufficient
lead cross-section.
Do not pull on power supply cable to unplug.
B
Change of direction of rotation!
(only for machines with three-phase
motor)
Depending on phase sequence it is possible
that the saw blade turns in the wrong direc-
tion. This can lead to the workpiece being
thrown about when attempting to make a cut.
Always check direction of rotation after every
connection to another outlet or circuit.
With a
wrong direction of rotation the phase
inverter on the power supply cable's plug
must be set:
1. After the saw is assembled, with all guards and
safety devices operational, connect it to the
power supply.
2. Raise saw blade fully.
3. Start saw and switch off immediately.
4. Watch the blade's direction of rotation from the
left-hand side of the saw.
It must turn clock-
wise.
5. If the blade turns counter-clockwise, disconnect
power supply cable from the saws combination
switch/plug.
6. With a flat bit screwdriver push the plug's phase
inverter in and turn by 180
°
.
A
Caution!
Do not turn the phase inverter by
the contact pins!
