Stationary or Flexible Mounting
 To ensure safe handling, the machine must be mounted
on a level and stable surface (e. g., workbench) prior to
using.
Mounting to a Working Surface (see figures A1 – A2)
– Fasten the power tool with suitable screw fasteners to the
working surface. The mounting holes 26 serve for this pur-
pose.
or
– Clamp the power tool with commercially available screw
clamps by the feet to the working surface.
Mounting to a Bosch Saw Stand
With the height-adjustable legs, Bosch GTA saw stands pro-
vide firm support for the power tool on any surface. The work-
piece supports of the saw stand are used for underlaying long
workpieces.
 Read all safety warnings and instructions included with
the worktable. Failure to observe safety warnings and in-
structions can lead to electrical shock, fire and/or cause
serious injuries.
 Assemble the worktable properly before mounting the
power tool. Perfect assembly is important in order to pre-
vent the risk of collapsing.
– Mount the power tool in transport position on the saw
stand.
Flexible Mounting (not recommended!) (see figure A3)
If, in exceptional circumstances, it is not possible to mount
the power tool on a flat and stable work surface, you can im-
provise by setting it up with the tilt protector and leg exten-
sions.
 Without the leg extensions 45 and the tilt protector 23,
the power tool will not be stable and can tip over espe-
cially when sawing maximum mitre angles.
– Mount the leg extensions 45 using the enclosed screws in
the mounting holes 26.
– Screw the tilt protector 23 in or out until the machine is po-
sitioned level on the working surface.

Dust/Chip Extraction

Dusts from materials such as lead-containing coatings, some
wood types, minerals and metal can be harmful to one's
health. Touching or breathing-in the dusts can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dusts, such as oak or beech dust, are considered as
carcinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be worked by specialists.
– Always use dust extraction.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the mate-
rials to be worked.
 Prevent dust accumulation at the workplace. Dusts can
easily ignite.

The dust/chip extraction can be blocked by dust, chips or
workpiece fragments.
– Switch the machine off and pull the mains plug from the
socket outlet.
– Wait until the saw blade has come to a complete stop.
– Determine the cause of the blockage and correct it.
External Dust Extraction
For dust extraction, a vacuum hose (size Ø 35 mm) can also
be connected to the chip ejector 2.
– Connect the vacuum hose with the chip ejector 2.
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

 When mounting the saw blade, wear protective gloves.
Danger of injury when touching the saw blade.
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.
Use only saw blades recommended by the tool manufacturer
and suitable for sawing the materials to be cut.
Mounting with Hex Socket Screw (see figures B1–B4)
Removing the Saw Blade:
– Bring the power tool into the working position.
– Turn the hex socket screw 48 with the hex key (5 mm) 36
and at the same time press the spindle lock 47 until it en-
gages.
– Hold the spindle lock 47 pressed and unscrew the hex
socket screw 48 in clockwise direction (left-hand thread!).
– Remove the clamping flange 49.
– Press locking switch 9 and swing back the retracting blade
guard 11 to the stop.
– Hold the retracting blade guard in this position and remove
the saw blade 12.
– Slowly guide the retracting blade guard downward again.
Mounting the Saw Blade:
If required, clean all parts to be mounted prior to assembly.
– Press locking switch 9, swing back the retracting blade
guard 11 to the stop and hold it in this position.
– Place the new saw blade onto the interior clamping flange
50.
 When mounting the saw blade, pay attention that the
cutting direction of the teeth (arrow direction on the
saw blade) corresponds with the direction of the arrow
on the blade guard!
– Slowly guide the retracting blade guard downward again.
– Place on the clamping flange 49 and the hex socket screw
48. Press the spindle lock 47 until it engages and tighten
the screw turning in anticlockwise direction.
