Minimal workpiece sizes
(= all workpieces that can be clamped left or right from the
saw blade with the supplied material clamp 40):
128 x 40 mm (length x width)
Cutting depth, max.
Workpiece against fence (0°/0°): 75 mm
Workpiece against distance-stop
(moved toward the front) (0°/0°): 100 mm
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 53.
– 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.
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 54 with the provided Allen key (4 mm) 17
and remove the old insert plates.
– Insert the new right-hand insert plate.
– Screw the insert plate with the screws 54 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 Ceiling Strips)
Profile strips/mouldings can be sawn in two different ways:
– Placed against the fence

Always make trial cuts with the mitre angle setting first on
scrap wood.
