 When mounting the saw blade, pay attention that the
cutting direction of the teeth (arrow direction on the
saw blade) corresponds with the direction of the arrow
on the blade guard!
– Slowly guide the retracting blade guard downward again.
– Place on the clamping flange 47 and the screw 46.
Press the spindle lock 45 until it engages and tighten the
screw turning in anticlockwise direction.
Operation
 Before any work on the machine itself, pull the mains
plug.
Transport Safety (see figure E)
The transport safety-lock 38 enables easier handling of the
machine when transporting to various working locations.
Releasing the Machine (Working Position)
– Push the tool arm by the handle 8 down a little in order to
relieve the transport safety-lock 38.
– Pull the transport safety-lock 38 completely outward.
– Guide the tool arm slowly upward.
Securing the Machine (Transport Position)
– Loosen the locking screw 33 if tightened. Pull the tool arm
completely to the front and tighten the locking screw
again.
– Screw adjusting screw 4 completely upward.
– To lock the saw table 15, tighten the locking knob 20.
– Press locking switch 9 and slowly guide the tool arm down-
ward by the handle 8.
– Guide the tool arm downward until the transport safety-
lock 38 can be pushed completely inward.
Preparing for Operation
Extending the Saw Table (see figure F)
Long workpieces must be underlaid or supported at their free
end.
The saw table can be extended left and right with the saw-ta-
ble extensions 13.
– Push clamping lever 16 upward.
– Pull out the saw-table extension 13 to the desired length.
– To lock the saw-table extension, push clamping lever 16
down again.
Moving the Fence (see figure G)
When sawing bevel angles, the adjustable fence 27 must be
pulled outward or removed completely.
Mitre/Bevel Angle
Vertical Horizontal
–2°... 45° 0° – Loosen locking screw 28.
– Pull the adjustable fence 27
completely outward.

Mitre/Bevel Angle
Vertical Horizontal
45°... 47° 0° – Remove locking screw 28.
– Pull the adjustable fence 27
completely outward.
combined mitre/bevel – Remove the adjustable fence
angle cuts upward.
Clamping the Workpiece (see figure H)
To ensure optimum working safety, the workpiece must al-
ways be firmly clamped.
Do not saw workpieces that are too small to clamp.
– Press the workpiece firmly against the fence 14.
– Insert the material clamp 29 provided into one of the holes
36 intended for it.
– Adapt the threaded rod 49 of the screw clamp to the work-
piece height.
– Firmly tighten the threaded rod 49, thus fastening the
workpiece.
Adjusting Mitre Angles
To ensure precise cuts, the basic adjustment of the machine
must be checked and adjusted as necessary after intensive
use (see "Checking and Adjusting the Basic Adjustment",
page 18).
Adjusting Standard Mitre Angles (see figure I)
For quick and precise adjustment of commonly used mitre an-
gles, detents 24 have been provided for on the saw table:
Left
0°
45° 31.6° 22.5° 15° 15° 22.5° 31.6° 45° 60°
– Loosen the locking knob 20 in case it is tightened.
– Pull lever 21 and rotate the saw table 15 left or right to the
requested detent.
– Release the lever again. The lever must be felt to engage in
the detent.
Adjusting Any Mitre Angle (see figure J)
The mitre angle can be set in the range from 52° (left side) to
60° (right side).
– Loosen the locking knob 20 in case it is tightened.
– Pull lever 21 and at the same time push the locking bracket
19 until it engages in the groove intended for this. The saw
table can be moved freely now.
– Turn the saw table 15 left or right by the locking knob until
the angle indicator 23 indicates the requested mitre angle.
For mitre angles greater than 45°:
Pull the saw-table extension 13 completely outward (see
"Extending the Saw Table", page 16).
– Tighten the locking knob 20 again.
– To loosen the lever 21 again (for adjusting standard mitre
angles), pull the lever upward.
The locking bracket 19 snaps back to its original position
and lever 21 can re-engage into the detents 24.
