Noise Information
Sound emission values determined according to
EN 62841-3-9.
Typically the A-weighted noise levels of the product are:
Sound pressure level 93 dB(A); Sound power level
106 dB(A). Uncertainty K =3 dB.
Wear hearing protection!
The noise emission value given in these instructions has been
measured in accordance with a standardised measuring pro-
cedure and may be used to compare power tools. It may also
be used for a preliminary estimation of noise emissions.
The noise emission value given represents the main applica-
tions of the power tool. However, if the power tool is used for
other applications, with different accessories or is poorly
maintained, the noise emission value may differ. This may sig-
nificantly increase noise emissions over the total working pe-
riod.
To estimate noise emissions accurately, the times when the
tool is switched off, or when it is running but not actually being
used, should also be taken into account. This may significant-
ly reduce noise emissions over the total working period.
Assembly
 Avoid unintentional starting of the machine. During as-
sembly and for all work on the machine, the power plug
must not be connected to the mains supply.
Delivery Scope
Before starting the operation of the machine for the first time,
check if all parts listed below have been supplied:
– Sliding mitre saw with mounted saw blade
– Material clamp 7
– Hex key 35
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 figure A)
– Fasten the power tool with suitable screw fasteners to the
working surface. The mounting holes 1 serve for this pur-
pose.

Mounting to a Bosch Saw Stand
With the height-adjustable legs, Bosch GTA saw stands pro-
mm 216
vide firm support for the power tool on any surface. The work-
mm 1.3–1.8
piece supports of the saw stand are used for underlaying long
mm 3.3
workpieces.
 Read all safety warnings and instructions included with
mm 30
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 B)
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 27 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
For dust extraction, a vacuum hose (size Ø 35 mm) can also
be connected to the chip ejector 13.
– Connect the vacuum hose with the chip ejector 13.
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.
