cess without touching the depth stop when moving the
glide arm.
– Firmly clamp the workpiece as appropriate for its dimen-
sions.
– Set the desired mitre and/or bevel angle if required.
– Switch the power tool on (see "Switching On (see figure
L)", page 23).
– Slowly guide the glide arm (27) downwards using the
handle (1).
– 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 (27) upwards.
Sawing with Slide Movement (see figure Q)
Maintain a firm grip on the handle before switching
u
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.
– Unlocking the glide arm(27) (see "Unlocking the Glide
Arm (see figure B1)", page 21).
Check whether the complete glide mechanism is ready to
be used by sliding the glide arm (27) back and forth.
– Firmly clamp the workpiece as appropriate for its dimen-
sions.
– Set the desired mitre and/or bevel angle if required.
– Pull the glide arm (27) away from the fence (6) by the
handle (1) until the saw blade is in front of the workpiece.
– Switch the power tool on (see "Switching On (see figure
L)", page 23).
– Slowly guide the glide arm (27) downwards using the
handle (1).
– Now push the glide arm (27) towards the fence (6) and
saw through the workpiece with uniform feed.
– Switch off the power tool and wait until the saw blade has
come to a complete stop.
– Slowly guide the glide arm (27) upwards.
Sawing Workpieces of the Same Length (see figure R)
The length stop (35) (accessory) can be used for easily saw-
ing workpieces to the same length.
The length stop can be mounted on either side of the saw
table extension (7).
– Loosen the locking screw (34) and move the length stop
(35) over the clamping screw (61).
– Retighten the locking screw (34).
– Set the saw table extension (7) to the required length
(see "Extending the Saw Table (see figure C)", page 22).
Adjusting the Depth Stop (Sawing the Groove) (see
figure S)
The depth stop needs to be adjusted if you wish to saw a
groove or use a spacer.
– Swivel the depth stop (29) outwards.
Bosch Power Tools
– Use the handle (1) to swivel the glide arm (27) into the
required position.
– Turn the adjusting screw (28) until the end of the screw
touches the depth stop (29).
– Slowly guide the glide arm (27) upwards.
Special workpieces
When sawing curved or round workpieces, these must be es-
pecially secured against slipping. At the cutting line, there
should be no gap between the workpiece, fence and saw
table.
If necessary, you will need to manufacture special fixtures.
Working on mouldings (base or crown
mouldings)
Mouldings can be sawn in two different ways:
Positioning of Base moulding
workpiece
– Placed against
the fence
– Lying flat on the
saw table
Furthermore, you can cut with or without the slide move-
ment depending on the width of the moulding.
Always check the set mitre and/or bevel angle first by mak-
ing trial cuts in scrap wood.
Adjusting the Laser
To ensure precise cuts, the laser beams must be checked
and adjusted as necessary after intensive use.
Experience and suitable special tools are required for this.
A Bosch after-sales service point will handle this work
quickly and reliably.
Note: To test the laser function, the power tool must be con-
nected to the power supply.
Never press the on/off switch while adjusting the
u
laser (e.g. when moving the glide arm). Accidental
starting of the power tool can lead to injuries.
– Bring the power tool into the work position.
– Turn the saw table (37) to the 0° detent (14). The lever
(12) must be felt to engage in the detent.
Checking (see figure T1)
– Draw a straight cutting line on the workpiece.
– Slowly guide the glide arm (27) downwards using the
handle (1).
– Position the workpiece so that the teeth of the saw blade
line up with the cutting line.
– Hold the workpiece in this position and slowly guide the
glide arm upwards.
– Clamp the workpiece.
– Switch on the laser beams with the switch (59).
