Noise/Vibration Information
Sound emission values determined according to
EN 60745-2-5.
Typically the A-weighted noise levels of the product are:
Sound pressure level 92 dB(A); Sound power level
103 dB(A). Uncertainty K =3 dB.
Wear hearing protection!
Vibration total values a
h
(triax vector sum) and uncertainty K
determined according to EN 60745:
Cutting wood: a
h
=3.0 m/s

, K=1.5 m/s

,
Cutting metal: a
h
=5.0 m/s

, K=1.5 m/s

.
The vibration level given in this information sheet has been meas-
ured 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 differ-
ent 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 sig-
nificantly 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.

Mounting/Replacing the Saw Blade

Before any work on the machine itself, pull the
mains plug.

When mounting the saw blade, wear protec-
tive gloves. Danger of injury when touching the saw
blade.

Only use saw blades that correspond with the
characteristic data given in the operating
instructions.

Do not under any circumstances use grinding
discs as the cutting tool.
Removal of the Saw Blade
(see figure A)
For changing the cutting tool, it is best to place the machine
on the face side of the motor housing.
• Press the spindle lock button
5 and keep it pressed.

The spindle lock button 5 may be actuated
only when the saw spindle is at a standstill.
Otherwise, the power tool can be damaged.
• With the Hex key 18 , unscrew the clamping bolt 19 turn-
ing in rotation direction

.
• Tilt back the retracting blade guard 12 and hold firmly.
• Remove the clamping flange 20 and the saw blade 21
from the saw spindle 23 .
Mounting the Saw Blade (see figure A)
For changing the cutting tool, it is best to place the machine
on the face side of the motor housing.
• Clean the saw blade
21 and all clamping parts to be
assembled.
• Tilt back the retracting blade guard 12 and hold firmly.
• Place the saw blade 21 on to the mounting flange 22 .
The cutting direction of the teeth (direction or arrow on
saw blade) and the direction-of-rotation arrow on the
blade guard 16 must correspond.
• Mount the clamping flange 20 and screw in the clamping
bolt 19 turning in rotation direction

. Observe correct
mounting position of mounting flange 22 and clamping
flange 20 .
• Press the spindle lock button 5 and keep it pressed.
• With the Hex key 18 , tighten the clamping bolt 19 turning
in rotation direction

. The tightening torque is between
6–9 Nm, which corresponds to hand tight plus ¼ turn.
