Switching Off
– To switch off the machine, release the
On/Off switch 4.
Reduced starting current
The electronic reduced starting current limits
the power consumption when switching the tool
on and enables operation from a 13 ampere
fuse.
Note: When the machine runs at full speed im-
mediately after switching on, the reduced start-
ing current has failed. The power tool should be
sent immediately to an after-sales service (for
addresses, see section "After-sales Service and
Customer Assistance", page 48).

Working Advice

General Sawing Instructions
For all cuts, it must first be ensured that the
saw blade at no time can come in contact
with the fence, screw clamps or other ma-
chine parts. Remove possibly mounted aux-
iliary stops or adjust them accordingly.
Protect the saw blade against impact and shock.
Do not subject the saw blade to lateral pressure.
Do not saw warped/bent workpieces. The work-
piece must always have a straight edge to face
against the fence.
Long workpieces must be underlaid or support-
ed at their free end. To additionally extend the
saw table, an extension bar 17 (accessory) can
be mounted both on the left and right side of the
power tool.
Illuminating the Work Area (see figure J)
Provide for sufficient lighting of the direct work-
ing area.
– For this, switch on the lighting unit 45 with
the switch 30.

Marking the Cutting Line (see figure K)
A laser beam indicates the cutting line of the
saw blade. This allows for exact positioning of
the workpiece for sawing, without having to
open the retracting blade guard.
– For this, switch the laser beam on with the
switch 29.
– Align the cutting mark on your workpiece
with reference to the right-hand edge of the
laser line.
Note: Before sawing, check if the cutting line is
still indicated correctly (see "Adjusting the La-
ser", page 46). The laser beam, as an example,
can misadjust due to vibrations after intensive
use.
Position of the Operator (see figure L)
Do not stand in a line with the saw blade in
front of the machine. Always stand aside of
the saw blade. This protects your body
against possible kickback.
– Keep hands, fingers and arms away from the
rotating saw blade.
– Do not cross your arms when operating the
tool arm.
