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.
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 17 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)
In exceptional cases, when it is not possible to mount the ma-
chine onto a level and stable work surface, it can be set up us-
ing the tilt protector.
Without the use of the tilt protector, the machine does
not stand safely and can tip over, especially when saw-
ing at maximum mitre/bevel angles.
– Screw the tilt protector 23 in or out until the machine is po-
sitioned level on the working surface.
Dust/Chip Extraction
Dust 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 dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment addi-
tives (chromate, wood preservative). Materials containing as-
bestos 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. Dust 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 (see figure B)
For dust extraction, a vacuum hose (size Ø 35 mm) can also
be connected to the chip ejector 34.
– Connect the vacuum hose with the chip ejector 34.
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. This prevents
overheating of the saw teeth during sawing.
Mounting with Hex Socket Screw (see figures C1–C3)
Removing the Saw Blade:
– Bring the power tool into the working position.
– Push the locking lever 13, swing the retracting blade guard
15 backward to the stop and let go of the locking lever.
Hold the retracting blade guard in this position.
– Turn the hex socket screw 45 with the hex key (6 mm) 37
and at the same time press the spindle lock 44 until it en-
gages.
– Hold the spindle lock 44 pressed and unscrew the hex
socket screw 45 in clockwise direction (left-hand thread!).
– Remove the clamping flange 46.
– Remove the saw blade 47.
– Slowly guide the retracting blade guard downward again.
Mounting the Saw Blade:
If required, clean all parts to be mounted prior to assembly.
– Push the locking lever 13, swing the retracting blade guard
15 backward to the stop and let go of the locking lever.
Hold the retracting blade guard in this position.
– Place the new saw blade onto the interior clamping flange
48.
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!
