Fitting individual components

– Carefully remove all parts included in the delivery from
their packaging.
– Remove all packing material from the power tool and the
accessories provided.
Fitting the locking knob (see figure a)
– Screw the locking knob (12) into the corresponding hole
above the lever (13).
Always tighten the locking knob (12) firmly before
u
sawing. Otherwise the saw blade can become wedged in
the workpiece.

Stationary or flexible mounting

To ensure safe handling, the power tool must be
u
mounted on a flat, stable work surface (e.g. work
bench) before use.
Mounting on a work surface (see figure b1)
– Use suitable screw fasteners to secure the power tool to
the work surface. The holes (9) are used for this purpose.
or
– Firmly clamp the base of the power tool to the work sur-
face with commercially available screw clamps.
Mounting on a Bosch saw stand
(see figure b2)
(GTA 2500 W, GTA 2500 Compact, GTA 2600, GTA
3800)
With the height-adjustable legs, Bosch GTA saw stands
provide firm support for the power tool on any surface. The
workpiece supports of the saw stand are used for underlay-
ing long workpieces.
Read all the warnings and instructions included with
u
the saw stand. Failure to observe the warnings and fol-
low instructions may result in electric shock, fire and/or
serious injury.
Assemble the saw stand properly before mounting the
u
power tool. Correct assembly is important to prevent the
risk of collapsing.
– Mount the power tool on the saw stand in the transport
position.

Dust/Chip Extraction

The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reac-
Capacity tions and/or cause respiratory illnesses in the user or in
people in the near vicinity.
80−100 %
Certain dusts, such as oak or beech dust, are classified as
60−80 %
carcinogenic, especially in conjunction with wood treatment
40−60 %
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be machined by specialists.
20−40 %
– Use a dust extraction system that is suitable for the ma-
5−20 %
terial wherever possible.
0−5 %
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in
the country of use must be observed.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
The dust/chip extraction system can be blocked by dust,
chips or fragments of the workpiece.
– Switch the power tool off and remove the battery.
– Wait until the saw blade has come to a complete stop.
– Determine the cause of the blockage and eliminate it.
External Dust Extraction
You can also attach a dust extraction hose (35 mm dia-
meter) to the extraction adapter (26) for extraction.
– Connect the dust extraction hose to the extraction
adapter (26).
The dust extractor must be suitable for the material being
worked.
When extracting dry dust that is especially detrimental to
health or carcinogenic, use a special dust extractor.
Cleaning the dust extraction adapter
To ensure optimum extraction, the dust extraction adapter
(26) must be cleaned regularly.
– Pull the dust extraction adapter (26) off the chip ejector
(24) with a twisting motion.
– Remove workpiece fragments and chippings.
– Reattach the dust extraction adapter to the chip ejector
with a twisting motion until it engages above the chip
ejector holding ring.

Changing the Saw Blade

Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
Wear protective gloves when fitting the saw blade.
u
There is a risk of injury when touching the saw blade.
Only use saw blades that have a maximum permitted speed
higher than the no-load speed of the power tool.
