Note: Before sawing, check if the cutting line is still indicated
correctly (see "Adjusting the Laser", page 36). The laser
beam, as an example, can misadjust due to vibrations after in-
tensive use.
Permissible Workpiece Dimensions
Maximum workpiece sizes:
Mitre/Bevel Angle
Horizontal
0°
45°

Minimum workpiece sizes (= all workpieces that can be
clamped left or right from the saw blade with the supplied ma-
terial clamp 40):
128 x 40 mm (length x width)
Cutting Off
– Firmly clamp the workpiece as appropriate for its dimen-
sions.
– Adjust the requested mitre and/or bevel angle.
– Switch on the machine.
– Press lever 22 and slowly guide the tool arm downward by
handle 4.
– Saw through the workpiece applying uniform feed.
– Switch off the machine and wait until the saw blade has
come to a complete stop.
– Guide the tool arm slowly upward.
Sawing Workpieces of the Same Length (see figure P)
The material stop 27 can be used for easily sawing workpiec-
es to the same length.
The material stop can be mounted on either side of the saw ta-
ble extension 15.
– Loosen lock screw 28 and swing the material stop 27 over
clamping screw 55.
– Retighten lock screw 28.
– Adjust the saw table extension 15 to the desired length
(see "Extending the Saw Table", page 32).
Special Workpieces
When sawing curved or round workpieces, these must be es-
pecially secured against slipping. At the cutting line, no gap
may exist between workpiece, fence and saw table.
Provide for special fixtures, if required.

Position of the Operator (see figure O)
 Do not stand in a line with the saw blade in front of the
machine. Always stand aside of the saw blade. This pro-
tects 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.

Replacing Insert Plates (see figure Q)
The red insert plates 39 can become worn after prolonged
use of the machine.
Replace defective insert plates.
– Bring the power tool into the working position.
– Unscrew screws 56 with the provided hex key (4 mm) 17
and remove the old insert plates.
– Insert the new right-hand insert plate.
– Screw the insert plate with the screws 56 as far as possible
to the right, so that the saw blade does not come in contact
with the insert plate throughout the complete possible rip-
ping length.
– Repeat the work steps in the same manner for the left-hand
insert plate.
Sawing Profile Strips/Mouldings (Floor and Ceil-
ing Strips)
Profile strips/mouldings can be sawn in two different ways:
– Placed against the fence
– Lying flat on the saw table.
Always make trial cuts with the mitre angle setting first on
scrap wood.
