Practical advice
General sawing instructions
u
Always tighten the locking knob (11) and the clamp-
ing handle (13) firmly before sawing. Otherwise the
saw blade can become wedged in the workpiece.
u
Always tighten the locking knob (11) and the clamp-
ing lever firmly before sawing. Otherwise the saw
blade can become wedged in the workpiece.
u
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.
Only saw materials which are permitted within the scope of
the intended use.
Do not saw warped/bent workpieces. The workpiece must
always have a straight edge to face against the fence.
The free end of long and heavy workpieces must have some-
thing placed underneath it or be supported.
Make sure that the retracting blade guard operates properly
and that it can move freely. The retracting blade guard must
open when the tool arm is guided downwards. When the tool
arm is guided upwards, the retracting blade guard must
close again over the saw blade and lock in the uppermost po-
sition of the tool arm.
Position of the operator (see figure M)
u
Do not stand in line with the saw blade in front of the
power tool. Always stand to the side of the saw blade.
This protects your body against possible kickback.
– Keep hands, fingers and arms away from the rotating saw
blade.
– Do not reach one hand across the other when in front of
the tool arm.
Replacing the Insert Plates (see figure P)
The red insert plates (9) can become worn after prolonged
use of the power tool.
Replace defective insert plates.
– Bring the power tool into the work position.
– Loosen the screws
(53) using the hex key (4 mm) (30)
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 (53) so that the saw blade does not come into
contact with the insert plate over the entire length of the
possible slide motion.
– Repeat the work steps in the same manner for the left-
hand insert plate.

Sawing
Sawing without slide movement (cutting off) (see
figure N)
– Slide the glide arm (23) all the way back and secure it in
this position.
Make sure that the depth stop
(25) is pressed all the way
in and that the adjusting screw (24) fits through the re-
cess without touching the depth stop when moving the
glide arm.
– Firmly clamp the workpiece as appropriate for its dimen-
sions.
– Set the required mitre and/or bevel angle as necessary.
– Switch on the power tool.
– Slowly guide the glide arm
(23) downwards using the
handle (3) .
– Saw through the workpiece applying uniform feed.
– Switch off the power tool and wait until the saw blade has
come to a complete stop.
– Slowly guide the glide arm (23) upwards.
Sawing with Slide Movement (see figure O)
u
Maintain a firm grip on the handle before switching
the power tool on and during the entire sawing pro-
cess. Ensure that the movement of the glide arm is
controlled during sawing.
The glide arm is very easy to
move and a moment of inattention could result in serious
injury.
– Unlock the glide arm (23) .
Check if the complete glide mechanism is operative by
sliding the glide arm
(23) back and forth.
– Firmly clamp the workpiece as appropriate for its dimen-
sions.
– Set the required mitre and/or bevel angle as necessary.
– Pull the glide arm
(23) away from the fence (8) by the
handle (3) until the saw blade is in front of the workpiece.
– Switch on the power tool.
– Slowly guide the glide arm
(23) downwards using the
handle (3) .
– Now push the glide arm (23) towards the fence (8) and
saw through the workpiece with uniform feed.
