Noise/Vibration Information

Measured sound values determined according to EN 60745.
Typically the A-weighted noise levels of the product are:
Sound pressure level 93 dB(A); Sound power level
104 dB(A). Uncertainty K =3 dB.
Wear hearing protection!
Vibration total values a (triax vector sum) and uncertainty K

The vibration emission level given in this information sheet has
been measured in accordance with a standardised test given in
EN 60745 and may be used to compare one tool with another.
It may be used for a preliminary assessment of exposure.
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 signif-
icantly reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator
from the effects of vibration such as: maintain the tool and the
accessories, keep hands warm, organise work patterns.

Assembly
Replacing/Inserting the Saw Blade
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.
When changing the saw blade, take care that the saw
blade holder is free of material residue, e.g. wood or
metal shavings.
Bosch Power Tools
Selecting a Saw Blade
An overview of recommended saw blades can be found at the
beginning of these operating instructions. Use only saw
blades with ½" universal shank. The saw blade should not be
longer than required for the intended cut.
Use a thin saw blade for narrow curve cuts.
Inserting the Saw Blade (see figure A)
Press the SDS clamping lever 5 forward and guide the saw

,
blade 1 behind the clamping plate 12 into the saw blade hold-
2 2
, K=1.5 m/s .
er 3. Release the SDS clamping lever 5.
Check the tight seating by pulling on the saw blade.
A loose saw blade can fall out and cause injury.
For certain work, the saw blade 1 can also be turned through
180° (with the teeth pointed upwards) and re-inserted again.
Removing the Saw Blade
Before removing, allow the saw blade to cool down.
Danger of injury when touching the hot saw blade.
Press the SDS clamping lever 5 forward and pull out the saw
blade 1. Release the SDS clamping lever 5.
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 infec-
tions 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 containing asbestos may only be worked by
specialists.
– 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
materials to be worked.
Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Operation
Operating Modes
Before any work on the machine itself, pull the mains
plug.
Pivoting and Retractable Footplate
(see figure B–C)
Due to its movability, the adjustable footplate 2 adapts to the
required angular position of the surface.
Depending on the application and the saw blade being used,
the footplate 2 can be moved variably in length direction.
Loosen the screws 13 with Allen key 9 and move the footplate
2 to the requested position. Tighten the screws 13 again and
check if the footplate 2 is tightly seated.
