Position of the Operator (see figure N)
 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.

Minimum workpiece sizes (= all workpieces that can be
clamped left or right from the saw blade with the supplied ma-
terial clamp 29): 100 x 40 mm (length x width)
Cutting depth, max. (0°/0°): 70 mm
Replacing Insert Plates (see figure O)
The red insert plates 19 can become worn after prolonged
use of the machine.
Replace defective insert plates.
– Bring the power tool into the working position.
– Unscrew the screws 54 with a hex key (4 mm) and remove
the old insert plates.
– Insert the new right-hand insert plate.
– Screw the insert plate as far as possible to the right with
the screws 54 so that the saw blade does not come into
contact with the insert plate over the complete length of
the possible slide motion.
– Repeat the work steps in the same manner for the left-hand
insert plate.
Sawing
 Always tighten the locking knob 21 and the clamping
lever 43 firmly before sawing. Otherwise the saw blade
can become wedged in the workpiece.
Adjusting the Speed
The speed regulator 40 enables continuously variable adjust-
ment of the speed of the power tool even during operation.
Note: Always set the suitable speed for the workpiece materi-
al (see table below). This prevents overheating of the saw
teeth during sawing.

Sawing without Slide Movement (Cutting Off)
(see figure P)
– For cuts without slide movement (small workpieces), loos-
en the locking screw 35 in case it is tightened. Slide the
tool arm to the stop in the direction of the fence 14 and
retighten the locking screw 35.
– Set the desired mitre angle.
– Firmly clamp the workpiece as appropriate for its dimen-
sions.
– Switch on the machine.
– Press locking switch 9 and slowly guide the tool arm down-
ward by the handle 8.
– 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 with Slide Movement
– For cuts using the slide device 1 (wide workpieces), loosen
the locking screw 35 in case it is tightened.
– Set the desired mitre angle.
– Firmly clamp the workpiece as appropriate for its dimen-
sions.
– Pull the tool arm away from the fence 14 far enough so that
the saw blade is in front of the workpiece.
– Switch on the machine.
– Press locking switch 9 and slowly guide the tool arm down-
ward by the handle 8.
– Press the tool arm in the direction of the fence 14 and 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 Q)
The material stop 38 (accessory) can be used for easily saw-
ing workpieces to the same length.
The material stop can be mounted on either side of the saw ta-
ble extension 13.
– Loosen lock screw 55 and swing the material stop 38 over
clamping screw 56.
– Retighten lock screw 55.
– Adjust the saw table extension 13 to the desired length
(see "Extending the Saw Table", page 31).
Adjusting the Depth Stop (Sawing Grooves) (see figure R)
The depth stop must be adjusted when a trench gap is to be
sawed.
– Swivel the depth stop 34 outward.
– Press locking lever 9 and tilt the tool arm to the desired po-
sition.
– Turn adjusting screw 4, until the screw end touches depth
stop 34.
– Guide the tool arm slowly upward.
