Mounting to a Working Surface (see figures D1 – D2)
– Fasten the power tool with suitable screw fasteners to the
working surface. The mounting holes 13 serve for this pur-
pose.
– 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.

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-treat-
ment additives (chromate, wood preservative). Materials
containing 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
materials to be worked.
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.
Integrated Dust Extraction (see figure C)
For basic dust collection, use the dust bag 21 provided.
– Press the clip of the dust bag 21 together and slide the
dust bag over the saw dust ejector 25. The clip must en-
gage into the groove of the saw dust ejector.
During sawing, the dust bag must never come into contact
with the movable machine parts.
Always empty the dust bag in good time.
 Check and clean the dust bag each time after using.
 When sawing aluminium, remove the dust bag to avoid
the risk of fire.

External Dust Extraction
For dust extraction, a vacuum hose (size Ø 36 mm) can also
be connected to the chip ejector 25.
– Connect the vacuum hose with the chip ejector 25.
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 Tool (see figures E1–E3)
 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.
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.
Removing the Saw Blade
– Bring the power tool into the working position.
– Press lever 1 and swing back the retracting blade guard 4
to the stop.
Hold the retracting blade guard in this position.
– Loosen the screw 32 with the cross-head screwdriver 28
provided until the fastening element of the retracting blade
guard can also be swung to the rear to the stop.
– Turn the hex socket screw 34 with the hex key 28 provided
while at the same time pressing the spindle lock 33 until it
engages.
– Hold the spindle lock 33 pressed and unscrew the hex
socket screw 34 in clockwise direction (left-hand thread!).
– Remove the clamping flange 35.
– Remove the saw blade 36.
Mounting the Saw Blade
If required, clean all parts to be mounted prior to assembly.
– Place the new saw blade onto the tool spindle 37.
 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!
– Place on the clamping flange 35 and the hex socket screw
34. Press the spindle lock 33 until it engages and tighten
the screw turning in anticlockwise direction.
– Push the retracting blade guard 4 down toward the front
until cross-head screw 32 engages in the corresponding
recess.
For this, it is possible that you must counter-hold the tool
arm by the handle to achieve the pre-tension of the retract-
ing blade guard.
– Fasten the retracting blade guard 4 again (tighten screw
32).
– Press lever 1 and guide the retracting blade guard down
again.
