External Dust Extraction (see figure H)
– Connect a vacuum hose to the chip ejector 10.
The vacuum cleaner must be suitable for the material being
worked.
When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum cleaner.
Changing the Saw Blade (see figures J1– J4)
 Before any work on the machine itself, pull the mains
plug.
 When mounting the saw blade, wear protective gloves.
Danger of injury when touching the saw blade.
Select the suitable saw blade for the material to be cut.
Use only saw blades whose maximum permitted speed is
higher than the no-load speed of the power tool.
Use only saw blades that correspond with the characteristic
data given in these operation instructions and that are tested
and marked in accordance with EN 847-1.
Removing the Saw Blade
– Remove the blade guard 3 and the laser unit 41 from the
riving knife 4.
– Loosen the screws of insert plate 5 with Allen key 13 and
remove the insert plate from the saw table.
– Turn crank 18 clockwise to the stop, so that the saw blade
28 is in the highest possible position above the saw table.
– Adjust a saw blade bevel angle of 45°. (see "Adjusting Bev-
el Angles", page 37)
– Turn the hex socket screw 57 with the hex key 13 provided
while at the same time pressing the spindle lock 56 until it
engages.
– Keep the spindle lock 56 pressed and unscrew the Allen
screw 57 in anticlockwise direction.
– Remove the exterior clamping flange 58.
– Remove the saw blade 28.
Mounting the Saw Blade
If required, clean all parts to be mounted prior to assembly.
– Place the new saw blade onto the interior clamping flange
59.
Note: Do not use saw blades that are too small. The clearance
between saw blade and riving knife must not exceed 5 mm
(max.).
 When mounting the saw blade, pay attention that the
cutting direction of the teeth (direction of arrow on
saw blade) corresponds with the direction of the arrow
on the blade guard and the lower saw blade cover!
– Mount the exterior clamping flange 58 and Allen screw 57.
Press the spindle lock 56 until it engages and tighten the
hexagon bolt in clockwise direction.
– Mount the insert plate 5 into the saw table.
– Mount laser unit 41 and blade guard 3 to the riving knife 4.
(see "Mounting the Laser Unit and the Blade Guard",
page 34)
– Check if the cutting line of the the saw blade is properly in-
dicated by the laser beam (see "Adjusting the Laser",
page 34).
The laser beam can be misadjusted when assembling the
laser unit 41 and the blade guard 3.

Operation
 Before any work on the machine itself, pull the mains
plug.
Transport and Working Position of the Saw Blade
Transport Position
– Turn crank 18 anticlockwise, until blade guard 3 faces
against the saw table 7.
Working Position
– Turn the crank 18 clockwise, until the teeth of the saw
blade 28 are positioned above the workpiece.
Increasing the Size of the Saw Table
Long workpieces must be underlaid or supported at their free
end.
The table extension 27 is used to widen or extend the saw ta-
ble 7. It can be mounted either on the left or right side, or to
the rear of the saw table. (see "Mounting the Table Exten-
sion", page 35)
Additionally, the free end of the workpiece can be supported
(e.g., with the Bosch PTA 1000 roller stand) (see figure K).
The roller balls ensure appropriate movability of the work-
piece.
Adjusting Mitre Angles
(Universal Guide)
The mitre angle can be set in the range from 90° (left side) to
90° (right side).
Adjusting Standard Mitre Angles (see figure L1)
For swift and precise setting of commonly used mitre angles,
the universal guide engages at the following standard angles:
Left
90° 75° 67,5° 60° 45°
0° 15° 22,5° 30° 45°
– Loosen wing bolt 33, if tightened.
– Turn angle stop 35 until the desired mitre angle engages.
– Tighten wing bolt 33 again.
Adjusting Any Mitre Angle (see figure L2)
– Loosen wing bolt 33, if tightened.
– Press lever 32 toward the front in the direction of the ar-
row and turn angle stop 35 until the mark on guide rail 31
indicates the desired mitre angle on the scale.
– Tighten wing bolt 33 again.
