– Pull the clamping lever (24) upwards until the clamping
wedge is positioned between the two articulated parts at
the bottom of the glide arm.
– This locks the glide arm (27), which is pushed all the way
back.

– Pull the glide arm (27) all the way forward.
– The glide mechanism is now completely extended.
– Pull the clamping lever (24) upwards until the clamping
wedge is positioned between the two articulated parts at

Moving the fence
(see figures D–E)
When sawing mitre and/or bevel angles, you have to pull the left-hand or right-hand adjustable fence (5) outwards depending
on the cutting direction, or remove it completely.

Adjusting the Damping of the Glide Arm (see figure F)
The glide mechanism of the glide arm (27) is preset at the
factory and is not damped when the power tool is delivered.
The damping of the glide mechanism can be adjusted using
the damper (52):
Hard – for more controlled work movements;
Soft – for fast saw cuts.
– For softer damping, loosen the two set screws (53) using
the hex key (4 mm) (16)
– or
– tighten the two set screws (53) for harder damping.
Clamping the Workpiece (see figure G)
To ensure maximum safety while working, the workpiece
must always be firmly clamped.
Do not saw workpieces that are too small to clamp firmly.
– Press the workpiece firmly against the fence (6).
– Insert the supplied screw clamp (18) into one of the holes
(54) intended for this purpose.
– Loosen the wing bolt (55) and adapt the screw clamp to
the workpiece. Tighten the wing bolt again.
– Firmly clamp the workpiece by turning the threaded rod
(56).

Preparing for Operation
Extending the Saw Table (see figure C)
The free end of long workpieces must have something
placed underneath it or be supported.
The saw table can be extended left and right using the saw
table extensions (7).
– Push the clamping lever (50) inwards.
– Pull out the saw table extension (7) to the required length
– To lock the saw table extension in place, push the clamp-
– Loosen the locking screw (51).
– Pull the left-hand adjustable fence (5) all the way out.
– Loosen the locking screw (51).
– Pull the left-hand adjustable fence (5) all the way out.
– Lift the adjustable fence upwards and out of the way.
– Remove the locking screw (51).
– Loosen the locking screw (51).
– Pull the right-hand adjustable fence (5) all the way out.
– Lift the adjustable fence upwards and out of the way.
Adjusting the horizontal mitre angle
To ensure precise cuts, the basic settings of the power tool
must be checked and adjusted as necessary after intensive
use (see "Checking and Adjusting the Basic Settings",
page 26).

Setting Standard Mitre Angles (see figure H)
For quick and precise setting of commonly used mitre
angles, detents (14) are provided on the saw table:
45°; 31.6°; 22.5°; 15°
– Loosen the locking knob (11) if it is tightened.
– Pull the lever (12) and rotate the saw table (37) left or
– Release the lever again. The lever must be felt to engage
