Note: Check the power tool for possible damage.
Before further use of the machine, check that all protective
devices are fully functional. Any lightly damaged parts must
be carefully checked to ensure flawless operation of the tool.
All parts must be properly mounted and all conditions fulfilled
that ensure faultless operation.
Damaged protective devices and parts must be immediately
replaced by an authorised service centre.
Mounting the Locking Knob (see figure A)
– Screw the locking knob 13 into the corresponding drill
hole above the lever 14.
 Always tighten the locking knob 13 firmly before saw-
ing. Otherwise the saw blade can become wedged in the
workpiece.
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 B1–B2)
– Fasten the power tool with suitable screw fasteners to the
working surface. The mounting holes 18 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.

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.

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)
– Mount extraction adapter 27 firmly onto chip ejector 37.
– Press the clamp of dust bag 1 together and mount the dust
bag over extraction adapter 27.
The clip must engage in the groove of the vacuuming
adapter.
– Release the dust-bag clamp again.
During sawing, the dust bag and the extraction adapter may
never come in contact with moving tool components.
Always empty the dust bag in good time.
External Dust Extraction
For dust extraction, you can also connect the extraction
adapter 27 to a vacuum hose (Ø 32 mm).
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 D1–D3)
 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.
– Loosen the screws 39 and 38 with the provided cross-
head screwdriver 30.
Do not completely unscrew the screws.
– Push the locking lever 4 and swing the retracting blade
guard 8 to the rear to the stop.
Hold the retracting blade guard in this position.
