– Swivel the tool arm by the handle (5) into the required
position.
– Turn the adjusting screw (23) until the end of the screw
touches the depth stop (22).
– Slowly guide the tool arm 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.
Replacing insert plates (see figure R)
The insert plate (10) can become worn after long use of the
power tool.
Replace a defective insert plate.
– Bring the power tool into the work position.
– Unscrew the screws (60) using a commercially available
cross-headed screwdriver and remove the old insert
plate (10).
– Insert the new insert plate and screw the screws (60) in
tight again.
Working on 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
Note: To test the laser function, the power tool must be con-
nected to the power supply.
While adjusting the laser (e.g. when moving the tool
u
arm), never activate the on/off switch. Starting the
power tool accidentally can lead to injuries.
– Bring the power tool into the work position.
– Turn the saw table (29) to the 0° detent (15). The lever
must be felt to engage in the detent.
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.
Bosch Power Tools
Checking (see figure S1)
– Draw a straight cutting line on the workpiece.
– Slowly guide the tool arm downwards using the
handle (5).
– 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
tool arm back up.
– Clamp the workpiece.
– Turn on the laser beam using the switch (36).
The laser beam must be flush with the cutting line on the
workpiece along its entire length, even if the tool arm is
guided downwards.
Setting (see figure S2)
– Turn the set screw (61) with a suitable screwdriver until
the laser beam is parallel to the entire length of the cut-
ting line on the workpiece.
One rotation anticlockwise moves the laser beam from left to
right; one rotation clockwise moves the laser beam from
right to left.
Checking and Adjusting the Basic Settings
To ensure precise cuts, the basic settings of the power tool
must be checked and adjusted as necessary after intensive
use.
Crown moulding
Experience and suitable special tools are required for this.
A Bosch after-sales service point will handle this work
quickly and reliably.
Setting the standard 0° bevel angle
– Bring the power tool into the work position.
– Turn the saw table (29) to the 0° detent (15). The lever
must be felt to engage in the detent.
– Pull the lock button (13) up.
– Turn the adjustment knob (21) slightly to the left and
swivel the tool arm from the right to the 0° position until
you hear it click into place in the 0° position.
– Push the lock button (13) back down.
Checking (see figure T1)
– Position the set square (62) with the 90° angle flush with
the saw blade (49) between the saw table (29) and the
saw blade on the saw table (29).
The leg of the set square must be flush with the saw blade
(49) along its entire length.
Setting (see figure T2)
– Loosen the lock nut of the stop screw (63) using a com-
mercially available box-ended or open-ended spanner.
– Turn the stop screw (63) as far in or out as needed until
the leg of the set square (62) is flush with the saw blade
along its entire length. – Push the lock button (13) back down.
– Then re-tighten the lock nut of the stop screw (63).
If the angle indicator (55) is not aligned with the 0° mark on
the scale (56) following adjustment, loosen the screw (65)
using a commercially available cross-headed screwdriver
