table extension

(11)

– Push the clamping lever

(10)

downwards.

– Pull out the saw table extension

(11)

to the required

length.

– To lock the saw table extension, pull the clamping lever

Setting the mitre angle (see figure E)

The mitre angle can be set between 0° and 45°.
Important settings are marked with corresponding markings
on the angle guide

(6)

. The 0° and 45° positions are secured

by the respective end stop.
– Loosen the clamping handle

(13)

of the angle guide

(6)

– Turn the angle guide

(6)

until the angle indicator

(33)

in-

dicates the desired mitre angle on the scale

(34)

– Retighten the clamping handle

(13)

Marking the Cutting Line (see figure F)

A laser beam shows you the cutting line of the saw blade.
This allows for exact positioning of the workpiece for sawing,
without having to open the retracting blade guard.
– To activate this, turn on the laser beam using the

switch

(19)

– Align your mark on the workpiece with the right-hand

edge of the laser line.

Note:

Before sawing, check whether the cutting line is still

indicated correctly. The laser beam can be misplaced due to
vibrations from intensive use, for example.

To ensure maximum safety while working, the workpiece
must always be firmly clamped. Do not saw workpieces that
are too small to clamp firmly.
The free end of long and heavy workpieces must have some-

Dust/chip extraction (see figure H)

The dust from materials such as lead paint, minerals and
metal can be harmful to human health. Touching or breath-
ing in this dust can trigger allergic reactions and/or cause
respiratory illnesses in the user or in people in the near vicin-
ity.
Certain kinds of metal dust are hazardous, especially in com-
bination with alloys such as zinc, aluminium or chrome. Ma-
terials containing asbestos may only be machined by special-
ists.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in
the country of use must be observed.
The saw blade

(31)

can become blocked by dust, chips or

workpiece fragments in the recess of the saw table

(25)

– Switch the power tool off and pull the mains plug out of

the socket.

– Wait until the saw blade has come to a complete stop.
