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 reac-
tions and/or lead to respiratory infections of the
user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in con-
nection with wood-treatment additives (chro-
mate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– Use dust extraction whenever possible.
– 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.
Integrated Dust Extraction
(see figure C)
For basic dust collection, use the dust bag
34
provided.
– Press the clip of the dust bag
34
together
and slide the dust bag over the saw dust
ejector
22
. The clip must engage into the
groove of the saw dust ejector.
During sawing, the dust bag must never come in-
to contact with the movable machine parts.
Always empty the dust bag in good time.
External Dust Extraction
For dust extraction, a vacuum hose (size
Ø 36 mm) can also be connected to the dust
ejector.
– Connect the vacuum hose with the sawdust
ejector
22
.
The vacuum cleaner must be suitable for the ma-
terial being worked.
When vacuuming dry dust that is especially det-
rimental to health or carcinogenic, use a special
vacuum cleaner.
Changing the Tool
(see figure D1
— D4)
f
Before any work on the machine itself, pull
the mains plug.
f
When mounting the saw blade, wear protec-
tive gloves.
Danger of injury when touching
the saw blade.
Use only saw blades whose maximum permitted
speed is higher than the no-load speed of the
power tool.
Use only saw blades that correspond with the
characteristic data given in these operation in-
structions and that are tested and marked in ac-
cordance with EN 847-1.
Removing the Saw Blade

35
and swing the re-
tracting blade guard

Mounting the Saw Blade
If required, clean all parts to be mounted prior
to assembly.
– Place the new saw blade onto the interior
clamping flange
41
.
f
When mounting the saw blade, pay atten-
tion that the cutting direction of the teeth
(arrow direction on the saw blade) corre-
sponds with the direction of the arrow on
the blade guard!
– Place on the clamping flange
39
and the Allen
screw
38
. Press the spindle lock
