The specifications apply to a rated voltage [U] of 230 V. These spe-
cifications may vary at different voltages and in country-specific mod-
els.

Noise/vibration information

Noise emission values determined according to

EN 62841-2-11

.

Typically, the A-weighted noise level of the power tool is:
Sound pressure level 

89

 dB(A); sound power level

100

 dB(A). Uncertainty K=

5

 dB.

Wear hearing protection

Vibration total values a

h

 (triax vector sum) and uncertainty K

The vibration level and noise emission value given in these
instructions have been measured in accordance with a
standardised measuring procedure and may be used to com-

pare power tools. They may also be used for a preliminary
estimation of vibration and noise emissions.
The stated vibration level and noise emission value repres-
ent the main applications of the power tool. However, if the
power tool is used for other applications, with different ap-
plication tools or is poorly maintained, the vibration level
and noise emission value may differ. This may significantly
increase the vibration and noise emissions over the total
working period.
To estimate vibration and 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 significantly reduce vibration and noise emissions
over the total working period.
Implement additional safety measures to protect the oper-
ator from the effects of vibration, such as servicing the
power tool and application tools, keeping their hands warm,
and organising workflows correctly.

Assembly

u

Pull the plug out of the socket before carrying out any
work on the power tool.

Inserting/changing the saw blade

u

When fitting or changing the saw blade, wear protect-
ive gloves.

 Blades are sharp and can become hot when

used for prolonged periods of time.

u

While replacing the saw blade, ensure that the saw
blade receptacle is free of material residue, e.g. wood
or metal chips. Take care that there are no sheared-off
pieces of shank in the saw blade receptacle.

Selecting the saw blade

You will find an overview of recommended saw blades at the
end of these operating instructions. Only use saw blades
with a 1/2" universal shank. The saw blade should not be
longer than required for the intended cut.
The shank thickness of the saw blade has to be 0.8–1.8 mm.
Use a narrow saw blade when sawing tight curves.

Inserting the saw blade (see figure A)

Press the SDS lever 

(9)

 forward and guide the saw blade 

(1)

behind the clamping plate  into the saw blade receptacle 

(3)

.

Release the SDS lever 

(9)

.

u

Check that it is seated securely by pulling the saw
blade.

 A loose saw blade can fall out and lead to injuries.

For particular jobs, the saw blade 

(1)

 can also be flipped

180° (teeth point upwards) and refitted.

Removing the saw blade (see figure B)

u

Let the saw blade cool down before removing it.

 There

is a risk of injury when touching the hot saw blade.

Press the SDS lever 

(9)

 forward and pull out the saw

blade 

(1)

. Release the SDS lever
