Noise/Vibration Information
Sound emission values determined according to
EN 61029-1, EN 61029-2-9.
Typically the A-weighted noise levels of the product are:
Sound pressure level 92 dB(A); Sound power level
105 dB(A). Uncertainty K =3 dB.
Wear hearing protection!
Vibration total values a (triax vector sum) and uncertainty K
h
determined according to EN 61029:
2 2
a =2.5 m/s , K=1.5 m/s .
h
The vibration emission level given in this information sheet
has been measured in accordance with a standardised test
given in EN 61029 and may be used to compare one tool with
another. It may be used for a preliminary assessment of expo-
sure.
The declared vibration emission level represents the main ap-
plications of the tool. However if the tool is used for different
applications, with different accessories or poorly maintained,
the vibration emission may differ. This may significantly in-
crease the exposure level over the total working period.
An estimation of the level of exposure to vibration should also
take into account the times when the tool is switched off or
when it is running but not actually doing the job. This may sig-
nificantly reduce the exposure level over the total working pe-
riod.
Identify additional safety measures to protect the operator
from the effects of vibration such as: maintain the tool and the
accessories, keep the hands warm, organisation of work pat-
terns.

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 39
– Hex key 38
– Hex key 58
– SDS bolt 31
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 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.
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 24 in or out until the machine is po-
sitioned level on the working surface.
