– Hold the tool arm in this position and retighten the clamp-
ing lever 14.
The clamping force of the clamping lever must securely
hold the position of the tool arm at any bevel angle.
Standard 33.9° Bevel Angle
– Standard angle 33.9°:
Pull adjustment knob 32 completely outward and turn it by
90°. Now tilt the tool arm via the handle 5 until the tool arm
can be heard to engage.
Adjusting the Handle (see figure L)
For a more convenient hand position, the handle 5 can be
turned to 4 different positions.
– Loosen clamp 3.
– Grasp and pull tongue 4 outward, then turn handle 5 until
it engages in the desired position.
– Let go of tongue 4 again and lock clamp 3.

Starting Operation

 Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
Switching On (see figure M)
– To start the machine, press the On/Off switch 25 and keep
it pressed.
Note: For safety reasons, the On/Off switch 25 cannot be
locked; it must remain pressed during the entire operation.
The locking lever 41 will only disengage the retracting blade
guard 8 after pressing button 6, so that the tool arm can be
lowered.
– For sawing, you must press button 6 in addition to actuat-
ing the On/Off switch.
To save energy, only switch the power tool on when using it.
Switching Off
– To switch off the machine, release the On/Off switch 25.

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 machine parts. Remove any mounted
auxiliary stops or adjust them accordingly.
Protect the saw blade against impact and shock. Do not sub-
ject the saw blade to lateral pressure.
Do not saw warped/bent workpieces. The workpiece must al-
ways have a straight edge to face against the fence.
Long workpieces must be underlaid or supported at their free
end.
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.

Replacing Insert Plates (see figure O)
The red insert plates 10 can become worn after prolonged
use of the machine.
Replace defective insert plates.
– Bring the power tool into the working position.
– Unscrew the screws 56 using the provided cross-head
screwdriver and remove the old insert plates.
– Insert the new insert plates.
– Set the bevel angle to 47° (leftward).
– Push locking lever 41 and completely lower the tool arm.
– Position the insert plate approx. 2 mm away from the saw
blade. Make sure that the saw blade does not come in con-
tact with the insert plates throughout the complete possi-
ble ripping length.
– Refasten the insert plate with the screws.
– Repeat the work steps for the other insert plate in the same
manner.
Sawing
Sawing without Slide Movement (Cutting Off) (see figure P)
– For cuts without slide movement (small workpieces), loos-
en the locking screw 29 in case it is tightened. Slide the
tool arm to the stop in the direction of the fence 18 and
retighten the locking screw 29.
– Firmly clamp the workpiece as appropriate for its dimen-
sions.
– Set the desired mitre angle.
– Switch on the machine.
– Press button 6 and guide the tool arm slowly downward
with handle 5.
– 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 23 (wide workpieces), loos-
en the locking screw 29 in case it is tightened.
– Firmly clamp the workpiece as appropriate for its dimen-
sions.
– Set the desired mitre angle.
– Pull the tool arm away from the fence 18 far enough so that
the saw blade is in front of the workpiece.
