Noise/Vibration Information

Sound emission values determined according to
EN 60745-2-11.
Typically the A-weighted noise levels of the product are:
Sound pressure level 90 dB(A); Sound power level
101 dB(A). Uncertainty K =3 dB.

The vibration 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
applications of the tool. However if the tool is used for different
applications, with different accessories or insertion tools or is
poorly maintained, the vibration emission may differ. This may
significantly increase 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 acces-
sories, keep the hands warm, organisation of work patterns.
Assembly
Replacing/Inserting the Saw Blade
 When mounting the saw blade, wear protective gloves.
Danger of injury when touching the saw blade.
Selecting a Saw Blade
An overview of recommended saw blades can be found at the
end of these instructions. Use only T-shank saw blades. The saw
blade should not be longer than required for the intended cut.
Use a thin saw blade for narrow curve cuts.
Inserting/Replacing the Saw Blade (see figure A)
 Insert the saw blade 10 until it latches in the SDS saw
blade receptacle 8.
While inserting the saw blade, pay attention that the back
of the saw blade is positioned in the groove of the guide
roller 9.
 Check the tight seating of the saw blade. A loose saw
blade can fall out and lead to injuries.
Slide the cover of the saw blade holder 8 upwards in the

direction of the arrow and remove the saw blade 10.

Splinter Guard (see figure B)
The splinter guard 14 (accessory) can prevent fraying of the
surface while sawing wood. The splinter guard can be used
only at a cutting angle of 0°.
Press the splinter guard 14 from the bottom into the base
plate 6.

Operating Modes
Orbital Action Settings
The four orbital action settings allow for optimal adaptation of
cutting speed, cutting capacity and cutting pattern to the
material being sawed.
The orbital action can be adjusted with the adjusting lever 7,
even during operation.

The optimal orbital action setting for the respective applica-
tion can be determined through practical testing. The follow-
ing recommendations apply:
– Select a lower orbital action setting (or switch it off) for a
– For thin materials such as sheet metal, switch the orbital
– For hard materials such as steel, work with low orbital action.
– For soft materials and when sawing in the direction of the
Adjusting the Cutting Angle (see figure C)
The base plate 6 can be swivelled by 45° to the left or right for
mitre cuts.
Loosen the screw 15 with the Allen key 4 and slide the base
plate 6 slightly towards the saw blade 10.
For adjustment of precise mitre angles, the base plate has
adjustment notches on the left and right at 0° and 45°. Swivel
the base plate 6 to the desired position according to the scale
16. Other mitre angles can be adjusted using a protractor.
Afterwards, push the base plate 6 to the stop toward the
mains cable.
Tighten the screw 15 again.
The splinter guard 14 can not be inserted for mitre cuts.
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 car-
cinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials con-
taining 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.
